Take a look into the DiSEqC spec available at + http://www.eutelsat.org/ for the complete list of commands. + + The burst signal is used in old equipments and by cheap satellite A/B + switches. + + Voltage, burst and 22kHz tone have to be consistent to the values encoded in + the DiSEqC commands. + + The complete sequence to set up switch and LNB according to the DiSEqC spec + looks like this: + + - stop continous tone + - setup polarisation voltage + - wait at least 15ms. + - send your DiSEqC commands using the FE_DISEQC_SEND_MASTER_CMD ioctl + - wait another 15ms + - send burst + - wait 15ms + - start the 22kHz tone when you tune to a transponder in the high band + + You can copy'n'paste this code sniplets from szap.c or diseqc.c, both + test programs are distributed with the linuxtv DVB driver source. All + DiSEqC related ioctls are passed to the frontend device filedescriptor. + + Depending on the equipment setup, you may or may not have to repeat the + DiSEqC commands (only commands, not the whole sequence) for cascaded devices + and can pack committed/uncommitted switch messages. See the DiSEqC spec for + details. + + In an advanced program, you probably want to send this sequence using an + asynchonous thread.

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.

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 new file mode 100755 index 000000000..bf62eb7ec --- /dev/null +++ b/dvb-spec/dvbapi/fig2pstex @@ -0,0 +1,6 @@ +#!/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

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. The naming scheme for the devices is the same wheter devfs +is used or not. + +More details about the data structures and function calls of +all the devices are described in the following chapters. + +\section{API include files} + +For each of the DVB devices a corresponding include file +exists. The DVB API include files should be included +in application sources with a partial path like: + +\begin{verbatim} +#include <linux/dvb/frontend.h> +\end{verbatim} + +To enable applications to support different API version, an additional +include file \texttt{linux/dvb/version.h} exists, which defines the +constant \texttt{DVB\_API\_VERSION}.

It is not necessary to implement every function in the demux\_t struct, +however (for example, a demux interface might support Section filtering, but +not TS or PES filtering). The API client is expected to check the value of any +function pointer before calling the function: the value of NULL means ``function +not available''. + +Whenever the functions of the demux API modify shared data, the possibilities +of lost update and race condition problems should be addressed, e.g. by +protecting parts of code with mutexes.

The client can get the handle of a section feed API by calling the function +allocate\_section\_feed() in the demux API. + +On demux platforms that provide section filtering in hardware, the Section Feed API +implementation provides a software wrapper for the demux hardware.

If either one is non-zero, the section should be descrambled either in + hardware or using the functions descramble\_mac\_address() and + descramble\_section\_payload() of the demux API.
