All, The issue of identification of television channels has been discussed in the ETSI TISPAN 14bis meeting of last week. The application of this identification is IPTV Presence: a presentity can publish which TV channel he is watching. The fact that ETSI TISPAN has requirements related to the identification of TV channels (e.g. tv:URI) is reflected in the recent update of our internet draft http://www.ietf.org/internet-drafts/draft-keesmaat-tvreg-01.txt. TISPAN WG1 (services) and WG2 (architecture) have defined the following requirements, relevant to our IETF APPS mailing list discussions on the tv:URI last October. ========== Start of TISPAN requirements ========== WI01044 (Draft TS 181 016): "Users' presence information may be related to, e.g., their connection status, location information, channel currently accessed or acceptable communication means. Presence information on channel currently accessed may be used by another user to instruct his set-top box with a single click to switch to the identified channel, or to instruct his set-top box to keep following identified channel changes. There may be significant delays in this following, depending on the update speed of the presence service. Any published presence information should only be disseminated other users that are authorised to receiving this presence information according to the presentity policies Users can also define a set of access rules to control access to their presence information. 6.2.1.1 It must be possible to define presence information related to the IPTV experience, e.g. channel currently accessed. The identification of the channel currently accessed shall be machine-readable. Language dependent information may also be made available to watchers." WI02048 (Draft TS 182 027): "The following specific IPTV attributes may also be supported: channel currently accessed, program currently watched, when available. content currently accessed. If the IPTV presence attribute "channel currently accessed" is supported, then the machine-readable part of the identification of the channel shall be globally unique. The term globally unique here means that there is no ambiguity in the identification of the channel if presentity and watcher (for terminology, see in ETSI 182 008) are with different network operators and/or in different countries." ========== End of TISPAN requirements ========== TISPAN WG4 (identifiers) has allocated a session in next TISPAN meeting dedicated to "Tv URI identifier and resolution". The meeting details for this session are as follows. Meeting: ETSI TISPAN 14ter Location: ETSI Headquarters, Sophia Antipolis Dates: 3-7 September 2007 WG4 session on tv:URI: Wednesday 5 September, 11:15-13:00 With this email, I would like to invite interested parties to participate and/or contribute to this WG4 session.
