Foreword This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit
35、 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 the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcas
36、t 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 professional association of broadcasting organizations whose work includes the co-ordination of its members activities
37、 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.

38、24 81 The Digital Video Broadcasting Project (DVB) is an industry-led consortium of broadcasters, manufacturers, network operators, software developers, regulatory bodies, content owners and others committed to designing global standards for the delivery of digital television and data services. DVB
39、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 transmission through interfacing, conditional access and interactivity for digital video, audio and data. The co
40、nsortium came together in 1993 to provide global standardisation, interoperability and future proof specifications. Introduction The present document provides specifications for the format of a file used to store DVB services, the “DVB File Format“. The specifications provided in the present documen
41、t provide for a file that can contain the full richness of experience that is offered by DVB compliant services. The file may be used to contain content received from a transmission, or it may contain content authored direct into the file which has been delivered by a mechanism out of the scope of t
42、he present document. The file format is derived from the ISO base media file format 30, and as such provides much commonality with many other similarly derived file formats, such as the MP4 file format 31 or the 3GP file format 15. Indeed, where appropriate, the file formats are interoperable to all
43、ow for the maximal mobility of content. ETSI ETSI TS 102 833 V1.2.1 (2011-03)8The format allows the storage of audio, video and other content in any of three main ways: encapsulated in a MPEG-2 Systems Transport Stream 27, stored as a reception hint track; encapsulated in an RTP stream, stored as a
44、reception hint track; and stored directly as media tracks. In addition, optional mechanisms are described that allow for the conversion of content between reception hint tracks and media tracks. To provide useful descriptive information to the user of what is contained within the file, a small amoun
45、t of mandatory descriptive metadata is included in the file. This allows any device to get a description of the content, even if it is not able to display the content. Additional metadata can be provided either in the extensible mandatory format, or in formats specific to certain DVB specifications.
46、 Content contained in files that follow the present document may be protected by CPCM 14. This allows the DVB File Format to be used for the storage and retrieval of CPCM protected content. ETSI ETSI TS 102 833 V1.2.1 (2011-03)91 Scope The present document specifies the File Format used to store and
47、 playback DVB services. The audio/video properties of the services that may be contained in this format are defined by specifications TS 101 154 3 for MPEG-2 Systems services, and TS 102 005 4 for RTP carried elementary stream services. The present document also specifies the storage of a range of a
48、dditional data relevant to the services. This includes: specification TS 102 825 14 when used to protect MPEG-2 Systems services; TV-Anytime Related metadata, as defined by TS 102 471 7, TS 102 323 5 and TS 102 539 10; any data that is carried with a transport stream as part of the service; and 3GPP
49、 Timed Text 16. Through the defined brands, the present document provides definitions of what may be contained in the file. However, the specification does not preclude any extensions from also being present, provided they do not conflict with the requirements of the present document. The present document does not require that the File Format be used internally by a device, and as such the specification can be viewed as an interoperability point. The use of the File Format is outside the scope of the present document. 2 References
