<p>The &DESCRIPTION; element is intended to be a child of a Jingle &CONTENT; element as specified in <cite>XEP-0166</cite>.</p>
<p>The &DESCRIPTION; element MUST possess a 'media' attribute that specifies the media type, such as "audio" or "video", where the media type SHOULD be as registered at &ianamedia;.</p>
<p>The &DESCRIPTION; element MAY possess a 'bandwidth' attribute that specifies the "session bandwidth" as described in Section 6.2 of <cite>RFC 3550</cite>, measured in kilobits per second as described in Section 5.2 of <cite>RFC 4566</cite>.</p>
<p>The encodings SHOULD be provided in order of preference by placing the most-preferred payload type as the first &PAYLOADTYPE; child of the &DESCRIPTION; element and the least-preferred payload type as the last child.</p>
<p>The allowable attributes of the &PAYLOADTYPE; element are as follows:</p>

<p>The SDP media type for Jingle RTP is "audio" (see Section 8.2.1 of <cite>RFC 4566</cite>) for audio media, "video" (see Section 8.2.1 of <cite>RFC 4566</cite>) for video media, etc.</p>
<p>The SDP media type for Jingle RTP is "audio" (see Section 8.2.1 of <cite>RFC 4566</cite>) for audio media, "video" (see Section 8.2.1 of <cite>RFC 4566</cite>) for video media, etc. The media type is reflected in the Jingle 'media' attribute.</p>
<p>The Jingle 'bandwidth' attribute SHALL be mapped to an SDP b= line, where the SDP &lt;bwtype&gt; parameter MUST be "AS" and the SDP &lt;bandwidth&gt; parameter contains the value of the Jingle 'bandwidth' attribute.</p>
<p>If the payload type is static (payload-type IDs 0 through 95 inclusive), it MUST be mapped to a media field defined in <cite>RFC 4566</cite>. The generic format for the media field is as follows:</p>
