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'.
