In a video conference, both ends of the link need to act as RTP clients and RTP servers. On the client end, the conferencing application needs to receive the media stream from an RTP session, order the packets, and render it onto the console. A conference with both audio and video would require two RTP sessions, one to handle each media type. On the server end, a media stream might need to be captured with a video camera, and the audio and video components would each be transmitted on a RTP session. If the video needed to be encoded in multiple formats for different receiver applications, several RTP sessions might be used.
