/**
 * The "proto" field describes the transport protocol used.
 * <p>
 * RFC4566 registers three values:
 * <ul>
 * <li><b>"RTP/AVP"</b> is a reference to RTP used under the RTP Profile for
 * Audio and Video Conferences with Minimal Control running over UDP/IP</li>
 * <li><b>"RTP/SAVP"</b> is a reference to the Secure Real-time Transport
 * Protocol</li>
 * <li><b>"udp"</b> indicates an unspecified protocol over UDP.</li>
 * </ul>
 * </p>
 * 
 * <p>
 * RFC4585 registers two values:
 * <li><b>"RTP/AVPF"</b> is an extension to the Audio-visual Profile (AVP) that
 * enables receivers to provide, statistically, more immediate feedback to the
 * senders and thus allows for short-term adaptation and efficient
 * feedback-based repair mechanisms to be implemented. This early feedback
 * profile (AVPF) maintains the AVP bandwidth constraints for RTCP and preserves
 * scalability to large groups.</li>
 * <li><b>"RTP/SAVPF"</b> refers to the AVPF profile on top of the Secure
 * Real-time Transport Protocol</li>
