15、E: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the st

16、andardization of radio and television receivers. The EBU is a professional association of broadcasting organizations whose work includes the co-ordination of its members activities in the technical, legal, programme-making and programme-exchange domains. The EBU has active members in about 60 countr

19、troduction The present document informs about the possibilities of an IPTV Terminal to make use of HbbTV features. Clause 4 of the present document contains requirements that are generic to any IPTV system when used in combination with HbbTV. Clause 5 contains requirements that are specific to parti

20、cular IPTV service discovery technologies. Clause 6 contains requirements that are specific to particular IPTV content delivery technologies. HbbTV terminals supporting the present document comply with the descriptions given in clause 4, and clauses of 5 and/or 6 depending on the technologies used f

21、or service discovery and content delivery. ETSI ETSI TS 103 555 V1.1.1 (2017-08)6 1 Scope The present document describes how IPTV Terminals can make use of HbbTV features. It does not, in any way, describe an IPTV delivery system itself. As such, technologies like fast channel change, retransmission

22、 and forward error correction are out-of-scope. Instead it defines how several technologies may be used in combination with HbbTV in a form that can be referenced by markets or organizations that have made choices. Please note that the scope of the present document only includes channels that use ei

23、ther MPEG-2 Transport Stream or MPEG DASH in the way defined in clause 6.2. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

36、g Protocol SD - applicationDescriptor/serviceBound is not required to be false; - applicationDescriptor/controlCode can take the same values as in a regular DVB- C/S/T broadcast and is not limited to AUTOSTART. When a channel or service delivered through MPEG DASH starts being presented, the termina

37、l shall apply clause 6.2.2.2 of ETSI TS 102 796 1, “Behaviour when selecting a broadcast service“ using the applicable XML AIT information. When an application signalling event stops being applicable and/or a new application signalling event becomes applicable, the terminal shall apply clause 6.2.2.

38、3 of ETSI TS 102 796 1, “Behaviour while a broadcast service is selected“ using the applicable XML AIT information (if any). The requirement in that clause to “include a mechanism to start and stop digital teletext applications“ shall also apply for TV channels or services delivered by MPEG DASH. NO

39、TE 2: Terminals may support recording and/or timeshift of content delivered by some content delivery protocols but not others. Support for recording of DASH is indicated by the recording element in the XML capabilities including a DASH attribute with value true as defined in clause 9.3.3 of the OIPF

40、 DAE specification 6. 6.3 Other Transport Protocols for Delivery of Linear Channels In the case other IP based transport protocols (such as RTSP) are used for the distribution of linear broadcast streams based on MPEG-2 transport stream, an integration with Hybrid Broadcast Broadband TV shall be don

41、e as follows: The rules of clause 4 of the present document are applied. The channelType of the video broadcast object is set to “undefined“. A channel change is supported via onid/tsid/sid or via the channel name (data to be retrieved during the channel set-up or via the service discovery mechanism

42、). 7 Content protection (informative) The protection, by technical means, of IPTV content is outside the scope of the present document except as follows: Protected content delivered in an MPEG-2 transport stream may be decrypted using a DVB Common Interface module as defined in ETSI TS 103 205 3. Su

43、pport for this will be indicated in the XML capabilities using the element as defined in clause 10.2.4 and clause 9.3.10 of the OIPF DAE specification 6. Content delivered in MPEG DASH may be protected using MPEG common encryption as defined in the DVB DASH specification 7.
