The standards are published -by ETSI and are available without cost from www.etsi.org (registration required). The main standard is ETSI TS 102 323. - -In the UK a subset of the TV-Anytime specification is broadcast on the DTV service -under the trade name "FreeView Plus". This patch is written for the UK version but -should work with the full specification (untested). - -TV-Anytime data is contained in Content Reference Identifiers (CRIDs). The syntax -of a CRID is described in RFC 4078; it is a URI-compliant string of the form: - - crid://<DNS name>/<data> - -in which <DNS name> is a registered internet domain name (RFC 1034) and <data> is -a free-format string. The <DNS Name> section relates to the content provider (TV -channel or company), and the <data> section to the programme. - -CRIDs are transmitted in the EIT as Content Identifier Descriptors, with descriptor -ID 0x76. To save bandwith only the <data> section is sent, the <DNS Name> part is -taken from the Default Authority Descriptor in the SDT, and the crid:// is assumed. - -A programme may have up to two CRIDs in its EPG entry. One identifies the specific -item of content which is being broadcast, while the other identifies a series of -programmes which this item belongs to. In FreeView Plus these CRIDs have crid_type -values 0x31 and 0x32 respectively (TV-Anytime uses values 0x01 and 0x02). - -To give an example, the programme "Torchwood" broadcast on channel BBC2 at 21:00 on -2008-01-16 had item CRID '54BXLC' and series CRID 'KCJ00C'. When the same programme -was repeated the following day on channel BBC3, the item CRID remained the same but -the series CRID was 'KCJ12C'. Meanwhile the episode broadcast on BBC2 one week -later on 2008-01-24 had CRID '54BXLD' but the same series as the previous week. Hence it is possible for a PVR to record an entire series by using the series CRID, or to find an alternative broadcast for an individual item if there is a clash with -another recording. - |
