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
   [RFC 2119].

   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'.
