<td width="100%"><pre>internet applications may reference specific codecs within the wave
and avi registries as follows:</pre>
<pre> * video/vnd.avi; codec=xxx identifies a specific video codec (i.e.,
xxx) within the avi registry.
* audio/vnd.wave; codec=yyy identifies a specific audio codec
(i.e., yyy) within the wave registry.</pre>
<pre>the following provides an authoritative reference for the
interpretation of the required "codec" parameter [rfc2361]. that is,
the current set of audio codecs that are registered within the wave
registry are enumerated in section a. section b enumerates the
current set of video codecs that have been registered to date within
the avi registry.
