A.1 MIME Types
26.2443GPP3GPP file format (3GP)Release 17Transparent end-to-end Packet-switched Streaming Service (PSS)TS
A.1.1 General
This registration is an update and replacement of RFC 3839. It applies to all files defined as using the ‘3GP’ file format and identified with a suitable brand in a 3GPP specification. The usual file suffix for all these files is ".3gp". The difference between the current registration and RFC 3839 is the inclusion of two optional parameters.
A.1.2 Files with audio but no visual content
The type "audio/3gpp" may be used for files containing audio but no visual presentation (neither video nor timed text, for example).
Type name: audio
Subtype name: 3gpp
Required parameters: none
Optional parameters:
codecs: is a single value or a comma-separated list that identifies the codec(s) needed for rendering the content contained (in tracks) of a file. The codecs parameter is defined in RFC 6381 [32]. The ISO file format name space and ISO syntax in clauses 3.3 and 3.4 of RFC 6381, respectively, shall be used together with additions defined in clause A.2.2 of the present document.
types: is a single value or a comma-separated list that identifies the MIME media types of the content contained (in items) in a file. It is defined in clause A.2.3 of the present document.
Encoding considerations: files are binary and should be transmitted in a suitable encoding without CR/LF conversion, 7-bit stripping etc.; base64 (RFC 4648 [35]) is a suitable encoding.
Security considerations: see the security considerations section in A.3 of the present document.
Interoperability considerations: The 3GPP organization has defined the specification, interoperability, and conformance. IMTC conducts interoperability testing.
Published specification: 3GPP TS 26.234, Release 5; 3GPP TS 26.244, Release 6 or later. 3GPP specifications are publicly accessible at the 3GPP web site, www.3gpp.org.
Applications which use this media type: Multi-media
Additional information: The type "audio/3gpp" may be used for files containing audio but no visual presentation. Files served under this type must not contain any visual material. (Note that timed text is visually presented and is considered to be visual material).
Magic number(s): None. However, the file-type box must occur first in the file, and must contain a 3GPP brand in its compatible brands list.
File extension(s): ‘3gp’ and ‘3gpp’ are both declared at http://www.nist.gov/nics/; 3gp is preferred
Macintosh File Type Code(s): ‘3gpp’
Intended usage: COMMON
Restrictions on usage: Note that this MIME type is used only for files; separate types are used for real-time transfer, such as for the RTP payload format for AMR audio (RFC 4867 [15]).

A.1.3 Any files
The type "video/3gpp" is valid for all files. It is valid to serve an audio-only file as "video/3gpp".
MIME media type name: video
MIME subtype name: 3gpp
Required parameters: none
Optional parameters:
codecs: is a single value or a comma-separated list that identifies the codec(s) needed for rendering the content contained (in tracks) of a file. The codecs parameter is defined in RFC 6381 [32].
