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.
