Foreword

This Technical Specification has been produced by the 3 Generation Partnership Project (3GPP).
The contents of the present document are subject to continuing work within the TSG and may change following formal
TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an
identifying change of release date and an increase in version number as follows:
Version x.y.z
where:
x the first digit:
1 presented to TSG for information;
2 presented to TSG for approval;
3 or greater indicates TSG approved document under change control.
y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
updates, etc.
z the third 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 seven 3GPP TSs:
3GPP TS 22.233 [1], 3GPP TS 26.233 [2], 3GPP TS 26.234 [3], 3GPP TS 26.245 [4], 3GPP TS 26.246 [5], 3GPP TS
26.247 [49] and the 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 language profile. The 3GPP TS 26.247 defines Progressive
Download and Dynamic Adaptive Streaming over HTTP. 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 started with Release 6. Earlier releases of the 3GPP file
format, the Timed text format and the 3GPP SMIL language profile can be found in TS 26.234. The 3GPP TS 26.247
started with Release-10. Earlier releases of the Adaptive HTTP Streaming can be found in 3GPP TS 26.234.
Introduction
A 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, PSS and MBMS for timed visual and aural multimedia.

1 Scope
The present document defines the 3GPP file format (3GP) as an instance of the ISO base media file format. The
definition addresses 3GPP specific features such as codec registration and conformance within the MMS, PSS and
MBMS services.
