7.1 Media Transport for enclosures
This section defines the media transport formats for Syndicated Feed Reception.
Syndicated Feed Reception supports progressive reception and rendering of 3GP files received using HTTP and packet switched streaming (PSS) sessions. A UE including reception support for 3GP files as defined in 3GPP TS 26.234  should support Basic profile, Extended-presentation profile and Progressive-download profile as defined 3GPP TS 26.244 . The UE shall support the mime type parameters as defined in RFC 4281 and should support Annex A of 3GPP TS 26.244 ,
Syndicated Feed Reception supports RTP streaming sessions as defined in Packet Switched Streaming (PSS) with URIs as enclosures. A UE including a Packet Switched Streaming (PSS) client as defined in 3GPP TS 26.234  should accept Packet Switched Streaming RTSP URIs as enclosures.
The Syndicated Feed Reader may receive linked files over MBMS and OMA Push.
