PREAMBLE - -The purpose of this License is to make a manual, textbook, or other -written document "free" in the sense of freedom: to assure everyone -the effective freedom to copy and redistribute it, with or without -modifying it, either commercially or noncommercially. Secondarily, -this License preserves for the author and publisher a way to get -credit for their work, while not being considered responsible for -modifications made by others. - -This License is a kind of "copyleft", which means that derivative -works of the document must themselves be free in the same sense. It -complements the GNU General Public License, which is a copyleft -license designed for free software. - -We have designed this License in order to use it for manuals for free -software, because free software needs free documentation: a free -program should come with manuals providing the same freedoms that the -software does. But this License is not limited to software manuals; -it can be used for any textual work, regardless of subject matter or -whether it is published as a printed book. We recommend this License -principally for works whose purpose is instruction or reference. - - -1. APPLICABILITY AND DEFINITIONS - -This License applies to any manual or other work that contains a -notice placed by the copyright holder saying it can be distributed -under the terms of this License. The "Document", below, refers to any -such manual or work. Any member of the public is a licensee, and is -addressed as "you". - -A "Modified Version" of the Document means any work containing the -Document or a portion of it, either copied verbatim, or with -modifications and/or translated into another language. - -A "Secondary Section" is a named appendix or a front-matter section of -the Document that deals exclusively with the relationship of the -publishers or authors of the Document to the Document's overall subject -(or to related matters) and contains nothing that could fall directly -within that overall subject. (For example, if the Document is in part a -textbook of mathematics, a Secondary Section may not explain any -mathematics.) The relationship could be a matter of historical -connection with the subject or with related matters, or of legal, -commercial, philosophical, ethical or political position regarding -them. - -The "Invariant Sections" are certain Secondary Sections whose titles -are designated, as being those of Invariant Sections, in the notice -that says that the Document is released under this License. - -The "Cover Texts" are certain short passages of text that are listed, -as Front-Cover Texts or Back-Cover Texts, in the notice that says that -the Document is released under this License. - -A "Transparent" copy of the Document means a machine-readable copy, -represented in a format whose specification is available to the -general public, whose contents can be viewed and edited directly and -straightforwardly with generic text editors or (for images composed of -pixels) generic paint programs or (for drawings) some widely available -drawing editor, and that is suitable for input to text formatters or -for automatic translation to a variety of formats suitable for input -to text formatters. A copy made in an otherwise Transparent file -format whose markup has been designed to thwart or discourage -subsequent modification by readers is not Transparent. A copy that is -not "Transparent" is called "Opaque". - -Examples of suitable formats for Transparent copies include plain -ASCII without markup, Texinfo input format, LaTeX input format, SGML -or XML using a publicly available DTD, and standard-conforming simple -HTML designed for human modification. Opaque formats include -PostScript, PDF, proprietary formats that can be read and edited only -by proprietary word processors, SGML or XML for which the DTD and/or -processing tools are not generally available, and the -machine-generated HTML produced by some word processors for output -purposes only. - -The "Title Page" means, for a printed book, the title page itself, -plus such following pages as are needed to hold, legibly, the material -this License requires to appear in the title page. For works in -formats which do not have any title page as such, "Title Page" means -the text near the most prominent appearance of the work's title, -preceding the beginning of the body of the text. - - -2. VERBATIM COPYING - -You may copy and distribute the Document in any medium, either -commercially or noncommercially, provided that this License, the -copyright notices, and the license notice saying this License applies -to the Document are reproduced in all copies, and that you add no other -conditions whatsoever to those of this License. You may not use -technical measures to obstruct or control the reading or further -copying of the copies you make or distribute. However, you may accept -compensation in exchange for copies. If you distribute a large enough -number of copies you must also follow the conditions in section 3. - -You may also lend copies, under the same conditions stated above, and -you may publicly display copies. - - -3. COPYING IN QUANTITY - -If you publish printed copies of the Document numbering more than 100, -and the Document's license notice requires Cover Texts, you must enclose -the copies in covers that carry, clearly and legibly, all these Cover -Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on -the back cover. Both covers must also clearly and legibly identify -you as the publisher of these copies. The front cover must present -the full title with all words of the title equally prominent and -visible. You may add other material on the covers in addition. -Copying with changes limited to the covers, as long as they preserve -the title of the Document and satisfy these conditions, can be treated -as verbatim copying in other respects. - -If the required texts for either cover are too voluminous to fit -legibly, you should put the first ones listed (as many as fit -reasonably) on the actual cover, and continue the rest onto adjacent -pages. - -If you publish or distribute Opaque copies of the Document numbering -more than 100, you must either include a machine-readable Transparent -copy along with each Opaque copy, or state in or with each Opaque copy -a publicly-accessible computer-network location containing a complete -Transparent copy of the Document, free of added material, which the -general network-using public has access to download anonymously at no -charge using public-standard network protocols. If you use the latter -option, you must take reasonably prudent steps, when you begin -distribution of Opaque copies in quantity, to ensure that this -Transparent copy will remain thus accessible at the stated location -until at least one year after the last time you distribute an Opaque -copy (directly or through your agents or retailers) of that edition to -the public. - -It is requested, but not required, that you contact the authors of the -Document well before redistributing any large number of copies, to give -them a chance to provide you with an updated version of the Document. - - -4. MODIFICATIONS - -You may copy and distribute a Modified Version of the Document under -the conditions of sections 2 and 3 above, provided that you release -the Modified Version under precisely this License, with the Modified -Version filling the role of the Document, thus licensing distribution -and modification of the Modified Version to whoever possesses a copy -of it. In addition, you must do these things in the Modified Version: - -A. Use in the Title Page (and on the covers, if any) a title distinct - from that of the Document, and from those of previous versions - (which should, if there were any, be listed in the History section - of the Document). You may use the same title as a previous version - if the original publisher of that version gives permission. -B. List on the Title Page, as authors, one or more persons or entities - responsible for authorship of the modifications in the Modified - Version, together with at least five of the principal authors of the - Document (all of its principal authors, if it has less than five). -C. State on the Title page the name of the publisher of the - Modified Version, as the publisher. -D. Preserve all the copyright notices of the Document. -E. Add an appropriate copyright notice for your modifications - adjacent to the other copyright notices. -F. Include, immediately after the copyright notices, a license notice - giving the public permission to use the Modified Version under the - terms of this License, in the form shown in the Addendum below. -G. Preserve in that license notice the full lists of Invariant Sections - and required Cover Texts given in the Document's license notice. -H. Include an unaltered copy of this License. -I. Preserve the section entitled "History", and its title, and add to - it an item stating at least the title, year, new authors, and - publisher of the Modified Version as given on the Title Page. If - there is no section entitled "History" in the Document, create one - stating the title, year, authors, and publisher of the Document as - given on its Title Page, then add an item describing the Modified - Version as stated in the previous sentence. -J. Preserve the network location, if any, given in the Document for - public access to a Transparent copy of the Document, and likewise - the network locations given in the Document for previous versions - it was based on. These may be placed in the "History" section. - You may omit a network location for a work that was published at - least four years before the Document itself, or if the original - publisher of the version it refers to gives permission. -K. In any section entitled "Acknowledgements" or "Dedications", - preserve the section's title, and preserve in the section all the - substance and tone of each of the contributor acknowledgements - and/or dedications given therein. -L. Preserve all the Invariant Sections of the Document, - unaltered in their text and in their titles. Section numbers - or the equivalent are not considered part of the section titles. -M. Delete any section entitled "Endorsements". Such a section - may not be included in the Modified Version. -N. Do not retitle any existing section as "Endorsements" - or to conflict in title with any Invariant Section. - -If the Modified Version includes new front-matter sections or -appendices that qualify as Secondary Sections and contain no material -copied from the Document, you may at your option designate some or all -of these sections as invariant. To do this, add their titles to the -list of Invariant Sections in the Modified Version's license notice. -These titles must be distinct from any other section titles. - -You may add a section entitled "Endorsements", provided it contains -nothing but endorsements of your Modified Version by various -parties--for example, statements of peer review or that the text has -been approved by an organization as the authoritative definition of a -standard. - -You may add a passage of up to five words as a Front-Cover Text, and a -passage of up to 25 words as a Back-Cover Text, to the end of the list -of Cover Texts in the Modified Version. Only one passage of -Front-Cover Text and one of Back-Cover Text may be added by (or -through arrangements made by) any one entity. If the Document already -includes a cover text for the same cover, previously added by you or -by arrangement made by the same entity you are acting on behalf of, -you may not add another; but you may replace the old one, on explicit -permission from the previous publisher that added the old one. - -The author(s) and publisher(s) of the Document do not by this License -give permission to use their names for publicity for or to assert or -imply endorsement of any Modified Version. - - -5. COMBINING DOCUMENTS - -You may combine the Document with other documents released under this -License, under the terms defined in section 4 above for modified -versions, provided that you include in the combination all of the -Invariant Sections of all of the original documents, unmodified, and -list them all as Invariant Sections of your combined work in its -license notice. - -The combined work need only contain one copy of this License, and -multiple identical Invariant Sections may be replaced with a single -copy. If there are multiple Invariant Sections with the same name but -different contents, make the title of each such section unique by -adding at the end of it, in parentheses, the name of the original -author or publisher of that section if known, or else a unique number. -Make the same adjustment to the section titles in the list of -Invariant Sections in the license notice of the combined work. - -In the combination, you must combine any sections entitled "History" -in the various original documents, forming one section entitled -"History"; likewise combine any sections entitled "Acknowledgements", -and any sections entitled "Dedications". You must delete all sections -entitled "Endorsements." - - -6. COLLECTIONS OF DOCUMENTS - -You may make a collection consisting of the Document and other documents -released under this License, and replace the individual copies of this -License in the various documents with a single copy that is included in -the collection, provided that you follow the rules of this License for -verbatim copying of each of the documents in all other respects. - -You may extract a single document from such a collection, and distribute -it individually under this License, provided you insert a copy of this -License into the extracted document, and follow this License in all -other respects regarding verbatim copying of that document. - - -7. AGGREGATION WITH INDEPENDENT WORKS - -A compilation of the Document or its derivatives with other separate -and independent documents or works, in or on a volume of a storage or -distribution medium, does not as a whole count as a Modified Version -of the Document, provided no compilation copyright is claimed for the -compilation. Such a compilation is called an "aggregate", and this -License does not apply to the other self-contained works thus compiled -with the Document, on account of their being thus compiled, if they -are not themselves derivative works of the Document. - -If the Cover Text requirement of section 3 is applicable to these -copies of the Document, then if the Document is less than one quarter -of the entire aggregate, the Document's Cover Texts may be placed on -covers that surround only the Document within the aggregate. -Otherwise they must appear on covers around the whole aggregate. - - -8. TRANSLATION - -Translation is considered a kind of modification, so you may -distribute translations of the Document under the terms of section 4. -Replacing Invariant Sections with translations requires special -permission from their copyright holders, but you may include -translations of some or all Invariant Sections in addition to the -original versions of these Invariant Sections. You may include a -translation of this License provided that you also include the -original English version of this License. In case of a disagreement -between the translation and the original English version of this -License, the original English version will prevail. - - -9. TERMINATION - -You may not copy, modify, sublicense, or distribute the Document except -as expressly provided for under this License. Any other attempt to -copy, modify, sublicense or distribute the Document is void, and will -automatically terminate your rights under this License. However, -parties who have received copies, or rights, from you under this -License will not have their licenses terminated so long as such -parties remain in full compliance. - - -10. FUTURE REVISIONS OF THIS LICENSE - -The Free Software Foundation may publish new, revised versions -of the GNU Free Documentation License from time to time. Such new -versions will be similar in spirit to the present version, but may -differ in detail to address new problems or concerns. See -http://www.gnu.org/copyleft/. - -Each version of the License is given a distinguishing version number. -If the Document specifies that a particular numbered version of this -License "or any later version" applies to it, you have the option of -following the terms and conditions either of that specified version or -of any later version that has been published (not as a draft) by the -Free Software Foundation. If the Document does not specify a version -number of this License, you may choose any version ever published (not -as a draft) by the Free Software Foundation. - - -ADDENDUM: How to use this License for your documents - -To use this License in a document you have written, include a copy of -the License in the document and put the following copyright and -license notices just after the title page: - - Copyright (c) YEAR YOUR NAME. - Permission is granted to copy, distribute and/or modify this document - under the terms of the GNU Free Documentation License, Version 1.1 - or any later version published by the Free Software Foundation; - with the Invariant Sections being LIST THEIR TITLES, with the - Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. - A copy of the license is included in the section entitled "GNU - Free Documentation License". - -If you have no Invariant Sections, write "with no Invariant Sections" -instead of saying which ones are invariant. If you have no -Front-Cover Texts, write "no Front-Cover Texts" instead of -"Front-Cover Texts being LIST"; likewise for Back-Cover Texts. - -If your document contains nontrivial examples of program code, we -recommend releasing these examples in parallel under your choice of -free software license, such as the GNU General Public License, -to permit their use in free software. diff --git a/dvb-spec/dvbapi/Makefile b/dvb-spec/dvbapi/Makefile index e741df6da..0ab91ee69 100644 --- a/dvb-spec/dvbapi/Makefile +++ b/dvb-spec/dvbapi/Makefile @@ -1,31 +1,153 @@ -all: dvbapi.ps dvbapi.pdf +SHELL=/bin/bash -TEXS= dvbapi.tex devices.tex video.tex audio.tex ca.tex net.tex frontend.tex \ - demux.tex kdapi.tex examples.tex intro.tex title.tex dvbstb.ps +SGMLS = \ + dvbapi.sgml \ + intro.xml \ + frontend.xml \ + isdbt.xml \ + demux.xml \ + video.xml \ + audio.xml \ + ca.xml \ + net.xml \ + kdapi.xml \ + examples.xml \ + fdl-appendix.xml \ + entities.xml \ -dvbapi.pdf: dvbapi.dvi - dvipdf $< $@ +PDFPICS = \ + dvbstb.pdf \ -dvbapi.ps: dvbapi.dvi - dvips -f $< -o $@ +GIFPICS = \ + dvbstb.png \ -dvbapi.dvi: dvbapi.bbl $(TEXS) - -latex dvbapi - -latex dvbapi +# Some Jade warnings for authors. +WARN = +#WARN = -w all -w duplicate -w net -dvbapi.bbl: $(TEXS) - -latex dvbapi - -bibtex dvbapi - -makeindex dvbapi +# Stylesheet customization. + # docbook/db2 syntax +CUSTOM_HTML = --dsl custom.dsl\#html +CUSTOM_PRINT = --dsl custom.dsl\#print + # xmlto syntax +CUSTOM_HTML_XMLTO = -m custom.xsl +CUSTOM_PRINT_XMLTO = -m custom.xsl -html: dvbapi.dvi - latex2html -address "LinuxTV DVB API" -long_titles 4 -split 3 dvbapi.tex +all: html-single -%.ps: %.fig - ./fig2pstex $< +html: html-build.stamp -clean: - rm -f dvbapi.dvi - rm -f *.aux *.bbl *.blg *.idx *.ilg *.ind *.log *.out *.toc - rm -f *.pdf *.pst *.ps +html-single: html-single-build.stamp + +pdf: pdf-build.stamp + +man: man-build.stamp + +man_install: man-build.stamp + install -d /usr/local/man/man2 + install -b man/* /usr/local/man/man2 + +.PHONY: links + +$(SGMLS): links +$(PDFPICS): links +$(GIFPICS): links + +links:: + ln -sf ../../linux/Documentation/DocBook/dvb/* . + ln -sf ../../linux/Documentation/DocBook/v4l/fdl-appendix.xml . + +entities.xml: Makefile $(SGMLS) + echo "<!-- Generated file!

Secondarily, -this License preserves for the author and publisher a way to get -credit for their work, while not being considered responsible for -modifications made by others. - -This License is a kind of ``copyleft'', which means that derivative -works of the document must themselves be free in the same sense. It -complements the GNU General Public License, which is a copyleft -license designed for free software. - -We have designed this License in order to use it for manuals for free -software, because free software needs free documentation: a free -program should come with manuals providing the same freedoms that the -software does. But this License is not limited to software manuals; -it can be used for any textual work, regardless of subject matter or -whether it is published as a printed book. We recommend this License -principally for works whose purpose is instruction or reference. - -\section{Applicability and Definitions} - -This License applies to any manual or other work that contains a -notice placed by the copyright holder saying it can be distributed -under the terms of this License. The ``Document'', below, refers to any -such manual or work. Any member of the public is a licensee, and is -addressed as ``you''. - -A ``Modified Version'' of the Document means any work containing the -Document or a portion of it, either copied verbatim, or with -modifications and/or translated into another language. - -A ``Secondary Section'' is a named appendix or a front-matter section of -the Document that deals exclusively with the relationship of the -publishers or authors of the Document to the Document's overall subject -(or to related matters) and contains nothing that could fall directly -within that overall subject. (For example, if the Document is in part a -textbook of mathematics, a Secondary Section may not explain any -mathematics.) The relationship could be a matter of historical -connection with the subject or with related matters, or of legal, -commercial, philosophical, ethical or political position regarding -them. - -The ``Invariant Sections'' are certain Secondary Sections whose titles -are designated, as being those of Invariant Sections, in the notice -that says that the Document is released under this License. - -The ``Cover Texts'' are certain short passages of text that are listed, -as Front-Cover Texts or Back-Cover Texts, in the notice that says that -the Document is released under this License. - -A ``Transparent'' copy of the Document means a machine-readable copy, -represented in a format whose specification is available to the -general public, whose contents can be viewed and edited directly and -straightforwardly with generic text editors or (for images composed of -pixels) generic paint programs or (for drawings) some widely available -drawing editor, and that is suitable for input to text formatters or -for automatic translation to a variety of formats suitable for input -to text formatters. A copy made in an otherwise Transparent file -format whose markup has been designed to thwart or discourage -subsequent modification by readers is not Transparent. A copy that is -not ``Transparent'' is called ``Opaque''. - -Examples of suitable formats for Transparent copies include plain -ASCII without markup, Texinfo input format, \LaTeX~input format, SGML -or XML using a publicly available DTD, and standard-conforming simple -HTML designed for human modification. Opaque formats include -PostScript, PDF, proprietary formats that can be read and edited only -by proprietary word processors, SGML or XML for which the DTD and/or -processing tools are not generally available, and the -machine-generated HTML produced by some word processors for output -purposes only. - -The ``Title Page'' means, for a printed book, the title page itself, -plus such following pages as are needed to hold, legibly, the material -this License requires to appear in the title page. For works in -formats which do not have any title page as such, ``Title Page'' means -the text near the most prominent appearance of the work's title, -preceding the beginning of the body of the text. - - -\section{Verbatim Copying} - -You may copy and distribute the Document in any medium, either -commercially or noncommercially, provided that this License, the -copyright notices, and the license notice saying this License applies -to the Document are reproduced in all copies, and that you add no other -conditions whatsoever to those of this License. You may not use -technical measures to obstruct or control the reading or further -copying of the copies you make or distribute. However, you may accept -compensation in exchange for copies. If you distribute a large enough -number of copies you must also follow the conditions in section 3. - -You may also lend copies, under the same conditions stated above, and -you may publicly display copies. - - -\section{Copying in Quantity} - -If you publish printed copies of the Document numbering more than 100, -and the Document's license notice requires Cover Texts, you must enclose -the copies in covers that carry, clearly and legibly, all these Cover -Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on -the back cover. Both covers must also clearly and legibly identify -you as the publisher of these copies. The front cover must present -the full title with all words of the title equally prominent and -visible. You may add other material on the covers in addition. -Copying with changes limited to the covers, as long as they preserve -the title of the Document and satisfy these conditions, can be treated -as verbatim copying in other respects. - -If the required texts for either cover are too voluminous to fit -legibly, you should put the first ones listed (as many as fit -reasonably) on the actual cover, and continue the rest onto adjacent -pages. - -If you publish or distribute Opaque copies of the Document numbering -more than 100, you must either include a machine-readable Transparent -copy along with each Opaque copy, or state in or with each Opaque copy -a publicly-accessible computer-network location containing a complete -Transparent copy of the Document, free of added material, which the -general network-using public has access to download anonymously at no -charge using public-standard network protocols. If you use the latter -option, you must take reasonably prudent steps, when you begin -distribution of Opaque copies in quantity, to ensure that this -Transparent copy will remain thus accessible at the stated location -until at least one year after the last time you distribute an Opaque -copy (directly or through your agents or retailers) of that edition to -the public. - -It is requested, but not required, that you contact the authors of the -Document well before redistributing any large number of copies, to give -them a chance to provide you with an updated version of the Document. - - -\section{Modifications} - -You may copy and distribute a Modified Version of the Document under -the conditions of sections 2 and 3 above, provided that you release -the Modified Version under precisely this License, with the Modified -Version filling the role of the Document, thus licensing distribution -and modification of the Modified Version to whoever possesses a copy -of it. In addition, you must do these things in the Modified Version: - -\begin{itemize} - -\item Use in the Title Page (and on the covers, if any) a title distinct - from that of the Document, and from those of previous versions - (which should, if there were any, be listed in the History section - of the Document). You may use the same title as a previous version - if the original publisher of that version gives permission. -\item List on the Title Page, as authors, one or more persons or entities - responsible for authorship of the modifications in the Modified - Version, together with at least five of the principal authors of the - Document (all of its principal authors, if it has less than five). -\item State on the Title page the name of the publisher of the - Modified Version, as the publisher. -\item Preserve all the copyright notices of the Document. -\item Add an appropriate copyright notice for your modifications - adjacent to the other copyright notices. -\item Include, immediately after the copyright notices, a license notice - giving the public permission to use the Modified Version under the - terms of this License, in the form shown in the Addendum below. -\item Preserve in that license notice the full lists of Invariant Sections - and required Cover Texts given in the Document's license notice. -\item Include an unaltered copy of this License. -\item Preserve the section entitled ``History'', and its title, and add to - it an item stating at least the title, year, new authors, and - publisher of the Modified Version as given on the Title Page. If - there is no section entitled ``History'' in the Document, create one - stating the title, year, authors, and publisher of the Document as - given on its Title Page, then add an item describing the Modified - Version as stated in the previous sentence. -\item Preserve the network location, if any, given in the Document for - public access to a Transparent copy of the Document, and likewise - the network locations given in the Document for previous versions - it was based on. These may be placed in the ``History'' section. - You may omit a network location for a work that was published at - least four years before the Document itself, or if the original - publisher of the version it refers to gives permission. -\item In any section entitled ``Acknowledgements'' or ``Dedications'', - preserve the section's title, and preserve in the section all the - substance and tone of each of the contributor acknowledgements - and/or dedications given therein. -\item Preserve all the Invariant Sections of the Document, - unaltered in their text and in their titles. Section numbers - or the equivalent are not considered part of the section titles. -\item Delete any section entitled ``Endorsements''. Such a section - may not be included in the Modified Version. -\item Do not retitle any existing section as ``Endorsements'' - or to conflict in title with any Invariant Section. - -\end{itemize} - -If the Modified Version includes new front-matter sections or -appendices that qualify as Secondary Sections and contain no material -copied from the Document, you may at your option designate some or all -of these sections as invariant. To do this, add their titles to the -list of Invariant Sections in the Modified Version's license notice. -These titles must be distinct from any other section titles. - -You may add a section entitled ``Endorsements'', provided it contains -nothing but endorsements of your Modified Version by various -parties -- for example, statements of peer review or that the text has -been approved by an organization as the authoritative definition of a -standard. - -You may add a passage of up to five words as a Front-Cover Text, and a -passage of up to 25 words as a Back-Cover Text, to the end of the list -of Cover Texts in the Modified Version. Only one passage of -Front-Cover Text and one of Back-Cover Text may be added by (or -through arrangements made by) any one entity. If the Document already -includes a cover text for the same cover, previously added by you or -by arrangement made by the same entity you are acting on behalf of, -you may not add another; but you may replace the old one, on explicit -permission from the previous publisher that added the old one. - -The author(s) and publisher(s) of the Document do not by this License -give permission to use their names for publicity for or to assert or -imply endorsement of any Modified Version. - - -\section{Combining Documents} - -You may combine the Document with other documents released under this -License, under the terms defined in section 4 above for modified -versions, provided that you include in the combination all of the -Invariant Sections of all of the original documents, unmodified, and -list them all as Invariant Sections of your combined work in its -license notice. - -The combined work need only contain one copy of this License, and -multiple identical Invariant Sections may be replaced with a single -copy. If there are multiple Invariant Sections with the same name but -different contents, make the title of each such section unique by -adding at the end of it, in parentheses, the name of the original -author or publisher of that section if known, or else a unique number. -Make the same adjustment to the section titles in the list of -Invariant Sections in the license notice of the combined work. - -In the combination, you must combine any sections entitled ``History'' -in the various original documents, forming one section entitled -``History''; likewise combine any sections entitled ``Acknowledgements'', -and any sections entitled ``Dedications''. You must delete all sections -entitled ``Endorsements.'' - - -\section{Collections of Documents} - -You may make a collection consisting of the Document and other documents -released under this License, and replace the individual copies of this -License in the various documents with a single copy that is included in -the collection, provided that you follow the rules of this License for -verbatim copying of each of the documents in all other respects. - -You may extract a single document from such a collection, and distribute -it individually under this License, provided you insert a copy of this -License into the extracted document, and follow this License in all -other respects regarding verbatim copying of that document. - - - -\section{Aggregation With Independent Works} - -A compilation of the Document or its derivatives with other separate -and independent documents or works, in or on a volume of a storage or -distribution medium, does not as a whole count as a Modified Version -of the Document, provided no compilation copyright is claimed for the -compilation. Such a compilation is called an ``aggregate'', and this -License does not apply to the other self-contained works thus compiled -with the Document, on account of their being thus compiled, if they -are not themselves derivative works of the Document. - -If the Cover Text requirement of section 3 is applicable to these -copies of the Document, then if the Document is less than one quarter -of the entire aggregate, the Document's Cover Texts may be placed on -covers that surround only the Document within the aggregate. -Otherwise they must appear on covers around the whole aggregate. - - -\section{Translation} - -Translation is considered a kind of modification, so you may -distribute translations of the Document under the terms of section 4. -Replacing Invariant Sections with translations requires special -permission from their copyright holders, but you may include -translations of some or all Invariant Sections in addition to the -original versions of these Invariant Sections. You may include a -translation of this License provided that you also include the -original English version of this License. In case of a disagreement -between the translation and the original English version of this -License, the original English version will prevail. - - -\section{Termination} - -You may not copy, modify, sublicense, or distribute the Document except -as expressly provided for under this License. Any other attempt to -copy, modify, sublicense or distribute the Document is void, and will -automatically terminate your rights under this License. However, -parties who have received copies, or rights, from you under this -License will not have their licenses terminated so long as such -parties remain in full compliance. - - -\section{Future Revisions of This License} - -The Free Software Foundation may publish new, revised versions -of the GNU Free Documentation License from time to time. Such new -versions will be similar in spirit to the present version, but may -differ in detail to address new problems or concerns. See -http://www.gnu.org/copyleft/. - -Each version of the License is given a distinguishing version number. -If the Document specifies that a particular numbered version of this -License "or any later version" applies to it, you have the option of -following the terms and conditions either of that specified version or -of any later version that has been published (not as a draft) by the -Free Software Foundation. If the Document does not specify a version -number of this License, you may choose any version ever published (not -as a draft) by the Free Software Foundation. - -\section*{ADDENDUM: How to use this License for your documents} - -To use this License in a document you have written, include a copy of -the License in the document and put the following copyright and -license notices just after the title page: - -\begin{quote} - - Copyright \copyright\ YEAR YOUR NAME. - Permission is granted to copy, distribute and/or modify this document - under the terms of the GNU Free Documentation License, Version 1.1 - or any later version published by the Free Software Foundation; - with the Invariant Sections being LIST THEIR TITLES, with the - Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. - A copy of the license is included in the section entitled ``GNU - Free Documentation License''. - -\end{quote} - -If you have no Invariant Sections, write ``with no Invariant Sections'' -instead of saying which ones are invariant. If you have no -Front-Cover Texts, write ``no Front-Cover Texts'' instead of -``Front-Cover Texts being LIST''; likewise for Back-Cover Texts. - -If your document contains nontrivial examples of program code, we -recommend releasing these examples in parallel under your choice of -free software license, such as the GNU General Public License, -to permit their use in free software. - diff --git a/dvb-spec/dvbapi/fig2pstex b/dvb-spec/dvbapi/fig2pstex deleted file mode 100755 index bf62eb7ec..000000000 --- a/dvb-spec/dvbapi/fig2pstex +++ /dev/null @@ -1,6 +0,0 @@ -#!/bin/sh -f=`basename $1 .fig` -fig2dev -L pstex $f.fig $f.ps -fig2dev -L pstex_t -p $f.ps $f.fig $f.pst2 -./getbb $f.pst2 $f.ps > $f.pst -rm $f.pst2

-Various DVB standards documents are available from -\texttt{http://www.dvb.org/} and/or \texttt{http://www.etsi.org/}. - -It is also necessary to know how to access unix/linux devices and how -to use ioctl calls.

The frontend down-converts and demodulates -this signal into an MPEG transport stream (TS). In case of a satellite -frontend, this includes a facility for satellite equipment control (SEC), -which allows control of LNB polarization, multi feed switches or -dish rotors. - -\item Conditional Access (CA) hardware like CI adapters and smartcard slots - -The complete TS is passed through the CA hardware. Programs to which -the user has access (controlled by the smart card) are decoded in real -time and re-inserted into the TS. - -\item Demultiplexer which filters the incoming DVB stream - -The demultiplexer splits the TS into its components like audio and video -streams. Besides usually several of such audio and video streams it also -contains data streams with information about the programs offered in this -or other streams of the same provider. - -\item MPEG2 audio and video decoder - -The main targets of the demultiplexer are the MPEG2 audio and video -decoders. After decoding they pass on the uncompressed audio -and video to the computer screen or (through a PAL/NTSC encoder) to -a TV set. -\end{itemize} - -Figure \ref{fig:dvbstb} shows a crude schematic of the control and data flow -between those components. - -On a DVB PCI card not all of these have to be present since some -functionality can be provided by the main CPU of the PC (e.g. MPEG picture -and sound decoding) or is not needed (e.g. for data-only uses like -``internet over satellite''). -Also not every card or STB provides conditional access hardware. - -\section{Linux DVB Devices} - -The Linux DVB API lets you control these hardware components -through currently six Unix-style character devices for -video, audio, frontend, demux, CA and IP-over-DVB networking. -The video and audio devices control the MPEG2 decoder hardware, -the frontend device the tuner and the DVB demodulator. -The demux device gives you control over the PES and section filters -of the hardware. If the hardware does not support filtering these filters -can be implemented in software. -Finally, the CA device controls all the conditional access capabilities -of the hardware. It can depend on the individual security requirements -of the platform, if and how many of the CA functions are made available -to the application through this device. - -\smallskip -All devices can be found in the \texttt{/dev} tree under -\texttt{/dev/dvb}. The individual devices are called -\begin{itemize} -\item \texttt{/dev/dvb/adapterN/audioM}, -\item \texttt{/dev/dvb/adapterN/videoM}, -\item \texttt{/dev/dvb/adapterN/frontendM}, -\item \texttt{/dev/dvb/adapterN/netM}, -\item \texttt{/dev/dvb/adapterN/demuxM}, -\item \texttt{/dev/dvb/adapterN/caM}, -\end{itemize} -where N enumerates the DVB PCI cards in a system starting from~0, -and M enumerates the devices of each type within each adapter, starting -from~0, too. -We will omit the ``\texttt{/dev/dvb/adapterN/}'' in the further dicussion of -these devices.

OVERVIEW AND LICENSING/DISCLAIMER + + +This driver kit contains Linux drivers for the WIS GO7007SB multi-format +video encoder. Only kernel version 2.6.x is supported. The video stream +is available through the Video4Linux2 API and the audio stream is available +through the ALSA API (or the OSS emulation layer of the ALSA system). + +The files in kernel/ and hotplug/ are licensed under the GNU General Public +License Version 2 from the Free Software Foundation. A copy of the license +is included in the file COPYING. + +The example applications in apps/ and C header files in include/ are +licensed under a permissive license included in the source files which +allows copying, modification and redistribution for any purpose without +attribution. + +The firmware files included in the firmware/ directory may be freely +redistributed only in conjunction with this document; but modification, +tampering and reverse engineering are prohibited. + +MICRONAS USA, INC., MAKES NO WARRANTIES TO ANY PERSON OR ENTITY WITH +RESPECT TO THE SOFTWARE OR ANY DERIVATIVES THEREOF OR ANY SERVICES OR +LICENSES AND DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION +WARRANTIES OF MERCHANTABILITY, SUPPORT, AND FITNESS FOR A PARTICULAR +PURPOSE AND NON-INFRINGEMENT. + + + 1. SYSTEM REQUIREMENTS + + +This driver requires Linux kernel 2.6. Kernel 2.4 is not supported. Using +kernel 2.6.10 or later is recommended, as earlier kernels are known to have +unstable USB 2.0 support. + +A fully built kernel source tree must be available. Typically this will be +linked from "/lib/modules/<KERNEL VERSION>/build" for convenience. If this +link does not exist, an extra parameter will need to be passed to the +`make` command. + +All vendor-built kernels should already be configured properly. However, +for custom-built kernels, the following options need to be enabled in the +kernel as built-in or modules: + + CONFIG_HOTPLUG - Support for hot-pluggable devices + CONFIG_MODULES - Enable loadable module support + CONFIG_KMOD - Automatic kernel module loading + CONFIG_FW_LOADER - Hotplug firmware loading support + CONFIG_I2C - I2C support + CONFIG_VIDEO_DEV - Video For Linux + CONFIG_SOUND - Sound card support + CONFIG_SND - Advanced Linux Sound Architecture + CONFIG_USB - Support for Host-side USB + CONFIG_USB_DEVICEFS - USB device filesystem + CONFIG_USB_EHCI_HCD - EHCI HCD (USB 2.0) support + +Additionally, to use the example application, the following options need to +be enabled in the ALSA section: + + CONFIG_SND_MIXER_OSS - OSS Mixer API + CONFIG_SND_PCM_OSS - OSS PCM (digital audio) API + +The hotplug scripts, along with the fxload utility, must also be installed. +These scripts can be obtained from <http://linux-hotplug.sourceforge.net/>. +Hotplugging is used for loading firmware into the Cypruss EZ-USB chip using +fxload and for loading firmware into the driver using the firmware agent. + + + 2. COMPILING AND INSTALLING THE DRIVER + + +Most users should be able to compile the driver by simply running: + + $ make + +in the top-level directory of the driver kit. First the kernel modules +will be built, followed by the example applications. + +If the build system is unable to locate the kernel source tree for the +currently-running kernel, or if the module should be built for a kernel +other than the currently-running kernel, an additional parameter will need +to be passed to make to specify the appropriate kernel source directory: + + $ make KERNELSRC=/usr/src/linux-2.6.10-custom3 + +Once the compile completes, the driver and firmware files should be +installed by running: + + $ make install + +The kernel modules will be placed in "/lib/modules/<KERNEL VERSION>/extra" +and the firmware files will be placed in the appropriate hotplug firmware +directory, usually /lib/firmware. In addition, USB maps and scripts will +be placed in /etc/hotplug/usb to enable fxload to initialize the EZ-USB +control chip when the device is connected. + + + 3. PAL/SECAM TUNER CONFIGURATION (TV402U-EU only) + + +The PAL model of the Plextor ConvertX TV402U may require additional +configuration to correctly select the appropriate TV frequency band and +audio subchannel. + +Users with a device other than the Plextor ConvertX TV402U-EU should skip +this section. + +The wide variety of PAL TV systems used in Europe requires that additional +information about the local TV standards be passed to the driver in order +to properly tune TV channels. The two necessary parameters are (a) the PAL +TV band, and (b) the audio subchannel format in use. + +In many cases, the appropriate TV band selection is passed to the driver +from applications. However, in some cases, the application only specifies +that the driver should use PAL but not the specific information about the +appropriate TV band. To work around this issue, the correct TV band may be +specified in the "force_band" parameter to the wis-sony-tuner module: + + TV band force_band + ------- ---------- + PAL B/G B + PAL I I + PAL D/K D + SECAM L L + +If the "force_band" parameter is specified, the driver will ignore any TV +band specified by applications and will always use the band provided in the +module parameter. + +The other parameter that can be specified is the audio subchannel format. +There are several stereo audio carrier systems in use, including NICAM and +three varieties of A2. To receive audio broadcast on one of these stereo +carriers, the "force_mpx_mode" parameter must be specified to the +wis-sony-tuner module. + + TV band Audio subcarrier force_mpx_mode + ------- ---------------- -------------- + PAL B/G Mono (default) 1 + PAL B/G A2 2 + PAL B/G NICAM 3 + PAL I Mono (default) 4 + PAL I NICAM 5 + PAL D/K Mono (default) 6 + PAL D/K A2 (1) 7 + PAL D/K A2 (2) 8 + PAL D/K A2 (3) 9 + PAL D/K NICAM 10 + SECAM L Mono (default) 11 + SECAM L NICAM 12 + +If the "force_mpx_mode" parameter is not specified, the correct mono-only +mode will be chosen based on the TV band. However, the tuner will not +receive stereo audio or bilingual broadcasts correctly. + +To pass the "force_band" or "force_mpx_mode" parameters to the +wis-sony-tuner module, the following line must be added to the modprobe +configuration file, which varies from one Linux distribution to another. + + options wis-sony-tuner force_band=B force_mpx_mode=2 + +The above example would force the tuner to the PAL B/G TV band and receive +stereo audio broadcasts on the A2 carrier. + +To verify that the configuration has been placed in the correct location, +execute: + + $ modprobe -c | grep wis-sony-tuner + +If the configuration line appears, then modprobe will pass the parameters +correctly the next time the wis-sony-tuner module is loaded into the +kernel. + + + 4. TESTING THE DRIVER + + +Because few Linux applications are able to correctly capture from +Video4Linux2 devices with only compressed formats supported, the new driver +should be tested with the "gorecord" application in the apps/ directory. + +First connect a video source to the device, such as a DVD player or VCR. +This will be captured to a file for testing the driver. If an input source +is unavailable, a test file can still be captured, but the video will be +black and the audio will be silent. + +This application will auto-detect the V4L2 and ALSA/OSS device names of the +hardware and will record video and audio to an AVI file for a specified +number of seconds. For example: + + $ apps/gorecord -duration 60 capture.avi + +If this application does not successfully record an AVI file, the error +messages produced by gorecord and recorded in the system log (usually in +/var/log/messages) should provide information to help resolve the problem. + +Supplying no parameters to gorecord will cause it to probe the available +devices and exit. Use the -help flag for usage information. + + + 5. USING THE DRIVER + + +The V4L2 device implemented by the driver provides a standard compressed +format API, within the following criteria: + + * Applications that only support the original Video4Linux1 API will not + be able to communicate with this driver at all. + + * No raw video modes are supported, so applications like xawtv that + expect only uncompressed video will not function. + + * Supported compression formats are: Motion-JPEG, MPEG1, MPEG2 and MPEG4. + + * MPEG video formats are delivered as Video Elementary Streams only. + Program Stream (PS), Transport Stream (TS) and Packetized Elementary + Stream (PES) formats are not supported. + + * Video parameters such as format and input port may not be changed while + the encoder is active. + + * The audio capture device only functions when the video encoder is + actively capturing video. Attempts to read from the audio device when + the encoder is inactive will result in an I/O error. + + * The native format of the audio device is 48Khz 2-channel 16-bit + little-endian PCM, delivered through the ALSA system. No audio + compression is implemented in the hardware. ALSA may convert to other + uncompressed formats on the fly. + +The include/ directory contains a C header file describing non-standard +features of the GO7007SB encoder, which are described below: + + + GO7007IOC_S_COMP_PARAMS, GO7007IOC_G_COMP_PARAMS + + These ioctls are used to negotiate general compression parameters. + + To query the current parameters, call the GO7007IOC_G_COMP_PARAMS ioctl + with a pointer to a struct go7007_comp_params.

The driver will return the current + parameters with any necessary changes to conform to the limitations of + the hardware or current compression mode. Any or all fields can be set + to zero to request a reasonable default value. If the driver is not + set to MPEG format, the EINVAL error code will be returned.

It can be tested using the gorecord +application in the apps/ directory of this SDK: + + $ apps/gorecord -vdevice /dev/video1 -noaudio test.avi + +Currently the frame resolution is fixed at 720x480 (NTSC) or 720x576 (PAL), +and the video standard must be specified to both the raw and the compressed +video devices (xawtv and gorecord, for example). + + +-------------------------------------------------------------------------- +RELEASE NOTES FOR WIS GO7007SB LINUX DRIVER +--------------------------------------------------------------------------- + +Last updated: 5 November 2005 + + - Release 0.9.7 includes new support for using udev to run fxload. The + install script should automatically detect whether the old hotplug + scripts or the new udev rules should be used. To force the use of + hotplug, run "make install USE_UDEV=n". To force the use of udev, run + "make install USE_UDEV=y". + + - Motion detection is supported but undocumented. Try the `modet` app + for a demonstration of how to use the facility. + + - Using USB2.0 devices such as the TV402U with USB1.1 HCDs or hubs can + cause buffer overruns and frame drops, even at low framerates, due to + inconsistency in the bitrate control mechanism. + + - On devices with an SAA7115, including the Plextor ConvertX, video height + values of 96, 128, 160, 192, 256, 320, and 384 do not work in NTSC mode. + All valid heights up to 512 work correctly in PAL mode. + + - The WIS Star Trek and PCI Voyager boards have no support yet for audio + or the TV tuner. diff --git a/linux/drivers/staging/go7007/s2250-board.c b/linux/drivers/staging/go7007/s2250-board.c new file mode 100644 index 000000000..f35f0776c --- /dev/null +++ b/linux/drivers/staging/go7007/s2250-board.c @@ -0,0 +1,620 @@ +/* + * Copyright (C) 2008 Sensoray Company Inc. + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License (Version 2) as + * published by the Free Software Foundation. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
