Video on Demand (VOD) Support

such as pay-per-view, or download content to a delivery device for future viewing. Delivery devices include computers, digital video recorders, personal video recorders, portable media players, mobile phones, and any system that can receive on-demand audio-visual content over a network.

The Integrated SBC supports different methods for delivering VOD packets over the Internet.

One method assumes that all flows of real-time streaming protocol (RTSP), real-time transport protocol (RTP), real-time control protocol (RTCP), and forward error correction (FEC) are delivered over one TCP connection that is initiated by the client side.

This method includes the following features:

•The TCP connection is always initiated by the client side.

•The local address and port number on the client or user side are specifically assigned by the signaling border element (SBE).

•The local address and port number on the back bone or server side are “any,” based on the media flow being supported by IPv6 No NAPT TCP with latching.

Another method assumes that all flows of RTSP are delivered over TCP connections that are initiated by the client side. Each flow of RTP for video, RTCP for video, and RTP for FEC is delivered over each

corresponding user datagram protocol (UDP) connection. In addition, when RTCP for FEC is used, it is delivered over a separate UDP connection.

This method includes the following features:

•The RTCP port number is always RTP port +1. This is done by the SBE instructing the DBE to set the Real-time Transport Protocol (RTP) Specific Behavior (rsb) property of the Gate Management package to rsb=ON at assignment of the RTCP port number.

•The SBE assigns the RTP and FEC port numbers because the media flow support is IPv6 No NAPT.
