14、hird digit is incremented when editorial only changes have been incorporated in the document.The 3GPP transparent end-to-end packet-switched streaming service (PSS) specification consists of six 3GPP TSs: 3GPP TS 22.233 1, 3GPPTS 26.233 2, 3GPP TS 26.234 3, 3GPP TS 26.245 4, 3GPP TS 26.246 5 and the

15、 present document.The TS 22.233 contains the service requirements for the PSS. The TS 26.233 provides an overview of the PSS. The TS 26.234 provides the details of protocol and codecs used by the PSS. The TS 26.245 defines the Timed text format used by the PSS. The TS 26.246 defines the 3GPP SMIL la

16、nguage profile. The present document defines the 3GPP file format (3GP) used by the PPS and MMS services.The TS 26.244 (present document), TS 26.245 and TS 26.246 start with Release 6. Earlier releases of the 3GPP file format, the Timed text format and the 3GPP SMIL language profile can be found in

17、TS 26.234.IntroductionA file format contains data in a structured way. The 3GPP file format can contain timing, structure and media data for multimedia streams. It is used by MMS and PSS for timed visual and aural multimedia.1 ScopeThe present document defines the 3GPP file format (3GP) as an instan

18、ce of the ISO base media file format. The definition addresses 3GPP specific features such as codec registration and conformance within the MMS and PSS services.2 ReferencesThe following documents contain provisions which, through reference in this text, constitute provisions of the present document

19、. References are either specific (identified by date of publication, edition number, version number, etc.) or nonspecific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a

20、 GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.1 3GPP TS 22.233: Transparent End-to-End Packet-switched Streaming Service; Stage 1.2 3GPP TS 26.233: Transparent end-to-end packet switched streaming service
