Abstract:
1. A method for communicating variable bit rate information, comprising the steps of: receiving at a receiving device a composite data stream transmitted across a link at a constant bit rate not less than a highest peak rate of a set of variable bit rate elementary data streams that comprise composite data stream; delaying processing at the receiving device of the composite data stream by a delay interval; and processing the composite data stream at the receiving device after said delay interval to synchronize packet decoding at the receiving device with a current system time, the processing occurring at a rate independent of the constant bit rate and including the steps of: recovering from the composite data stream clock references; de-multiplexing the composite data stream into constituent elementary data streams; determining if any elementary data stream has a packet with a time stamp matching the current system time, and if so, determining whether the packet has a packet decode stamp matching the current system time, and if so, then decoding the packet; determining if the packet has a presentation time stamp matching the current system time, and if so, rendering the packet.
