Abstract

   This document serves to register and document the standard MIME types

   associated with the 3GPP multimedia file format, which is part of the

   family based on the ISO Media File Format.

1.  Introduction

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",

   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this

   document are to be interpreted as described in BCP 14, RFC 2119

   [RFC2119].

   The third-generation partnership project (3GPP) for third-generation

   cellular telephony has defined a standard file format to contain

   audio/visual sequences which may be downloaded to cellular phones

   [3GPP].  At the time of writing, the 3GPP file format (3GP) can

   contain H.263 or MPEG-4 video, and AMR Narrow-band speech, AMR wide-

   band speech, or AAC audio, and 3GPP timed text.

   Within the file, as with all files in the 'ISO' family, there is an

   intrinsic file-type box, which identifies those specifications to

   which the file complies, and which players (possibly compliant with

   only one specification) are permitted by the content author to play

   the file.  This identification is through four-letter 'brands'.

Castagno & Singer           Standards Track                     [Page 1]

RFC 3839            MIME Type Registrations for 3GPP           July 2004

   Files identified by the MIME [MIME1] type defined here MUST contain a

   brand defined in a standard issued by 3GPP that can apply to 3GPP

   files, in their compatible brands list.

   The MIME types defined here are needed to correctly identify such

   files when they are served over HTTP, included in multi-part

   documents, or used in other places where MIME types are used.
