Foreword This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Norm
19、alisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE 1: 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 tri
20、partite 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 professional association of broadcasting organizations whose work includes the co-ordination of its members activities in the techni
21、cal, 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.

22、ka Project 147 was established in 1987, with funding from the European Commission, to develop a system for the broadcasting of audio and data to fixed, portable or mobile receivers. Their work resulted in the publication of European Standard, EN 300 401 1, for DAB (see note) which now has worldwide
23、acceptance. The members of the Eureka Project 147 are drawn from broadcasting organizations and telecommunication providers together with companies from the professional and consumer electronics industry.

24、I TS 102 428 V1.2.1 (2009-04)61 Scope The present document specifies the user application for DMB video services carried via DAB. It also includes profile definitions for the application. The user application is delivered using the MSC stream data mode (EN 300 401 1) including additional error prote
25、ction (TS 102 427 2). The present document defines the components of the DMB video services; the content compression, the synchronization mechanism and multiplexing mechanism. The components of the DMB service are the video object, the audio object, and the auxiliary media objects. All the objects a
26、re packetized and synchronized using MPEG-4 SL (ISO/IEC 14496-1 4). The present document also specifies the mechanism for the multiplexing of the multimedia data using MPEG-2 TS (ISO/IEC 14496-1 4). For efficiency, some appropriate restrictions to MPEG-4 SL and MPEG-2 TS are specified. 2 References

45、ce Locator 4 Architecture The DMB video service user application described in the present document is delivered through the MSC stream data mode (EN 300 4011). In order to maintain extremely low bit error rates, the service uses the additional error protection mechanism described in TS 102 427 2. Th
46、e DMB video service is composed of three layers; content compression layer, synchronization layer, and transport layer. In the content compression layer, DMB specifies a specific compression method for the video content, a specific compression method for the audio content and a specific scene descri
47、ption for interactive content. To synchronize the audio and video content, both temporally and spatially, MPEG-4 SL is employed in the synchronization layer. In the transport layer, MPEG-2 TS with some appropriate restrictions is employed for the multiplexing of the compressed audio and video conten
