ABSTRACT:
In an interactive video-on-demand system, real-time programs are encoded as a transport stream including a plurality of transport stream packets. Some of the transport stream packets include timing signals indicating the real time of the program. The transport stream packets are formatted into transport cells for transport over an asynchronous transfer mode network from a source to a destination. The cells are transported at a transport rate which is determined by a network clock. The transport rate is chosen to deliver the transport stream faster than the real time of the program. While transporting the transport stream, it is determined if the transport stream is being transported ahead of the real time of the program. In this case, idle cells are injected into the transport stream to have the program arrive at the destination in the real time of the program.
