Foreword This Technical Specification (TS
33、) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate
34、 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 standardization of radio and television receivers. The EBU is a profes
35、sional 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 countries in the European broadcasting area; its headquarters is in Geneva

European Broadcasting Union CH-1218 GRAND SACONNEX (Geneva) Switzerland Tel: +41 22 717 21 11 Fax: +41 22 717 24 81 The Digital Video Broadcasting Project (DVB) is an industry-led consortium of broadcasters, manufacturers, network operators, software developers, regulatory bodies, content owners a
37、nd others committed to designing global standards for the delivery of digital television and data services. DVB fosters market driven solutions that meet the needs and economic circumstances of broadcast industry stakeholders and consumers. DVB standards cover all aspects of digital television from
38、transmission through interfacing, conditional access and interactivity for digital video, audio and data. The consortium came together in 1993 to provide global standardisation, interoperability and future proof specifications. Introduction The present document addresses the use of video and audio c
39、oding in DVB services delivered over IP protocols. It specifies the use of H.264/AVC video and SVC video as specified in ITU-T Recommendation H.264 1 and ISO/IEC 14496-10 2, VC-1 video as specified in SMPTE 421M 10, MPEG-4 AAC/HE AAC/HE AAC v2 audio as specified in ISO/IEC 14496-3 3, MPEG Surround a
40、udio as specified in ISO/IEC 23003-1 20, Extended AMR-WB (AMR-WB+) audio as specified in TS 126 290 8 and AC-3 and Enhanced AC-3 audio as specified in TS 102 366 13. The present document adopts a “toolbox“ approach for the general case of DVB applications delivered directly over IP. A common generic
41、 toolbox is used by all DVB services, where each DVB application can select the most appropriate tool from within that toolbox. Annex B of the present document specifies application-specific constraints on the use of the toolbox for the particular case of DVB IP Datacast services. Clauses 4 to 6 of
42、the present document provide the Digital Video Broadcasting (DVB) specifications for the systems, video, and audio layer, respectively. For information, some of the key features are summarized below, but clauses 4 to 6 should be consulted for all normative specifications: ETSI ETSI TS 102 005 V1.4.1

46、 at level ML as specified in 10 or else any combination of those. Capability B IP-IRDs that are capable of decoding bitstreams conforming to H.264/AVC Scalable Baseline profile at Level 1.2 are also capable of decoding bitstreams conforming to H.264/AVC Baseline profile at Level 1.2 with constraint_

Capability C IP-IRDs are capable of decoding either bitstreams conforming to H.264/AVC Baseline profile at Level 2 with constraint_set1_flag being equal to 1 as specified in 1 or else bitstreams conforming to H.264/AVC Scalable Baseline profile at Level 2 as specified in
48、1 or else bitstreams conforming to VC-1 Advanced Profile at level L0 as specified in 10 or else any combination of those. Capability C IP-IRDs that are capable of decoding bitstreams conforming to H.264/AVC Scalable Baseline profile at Level 2 are also capable of decoding bitstreams conforming to H.
