Abstract: A highly flexible and scalable architecture implements TDM bridge and related functions for network to telecom interface applications like voice over Internet. A very small packet size minimizes packetization delay so that VOIP can be realized without expensive echo cancellation. High density enables processing 4K simultaneous voice channels in real time on a single, compact circuit board.

Abstract: A highly flexible and scalable architecture implements a wide variety of protocol bridging, including ATM SARing (segmentation and reassembly) operations and related functions with single call granularity for network to telecom interface applications such as voice over Internet. A very small packet size minimizes packetization delay so that VOIP can be realized without expensive echo cancellation.

Abstract: An apparatus for video clock and framing signal extraction by transport stream snooping parses MPEG2 Transport Packet headers from a transmission transport stream and partially decodes the headers to identify those corresponding to a specified packet identification (PID). From the specified headers a program clock is decoded and compared with a recovered program clock generated by a local clock oscillator and a local clock counter. The comparison is used to finely tune the recovered program clock frequency. Also from the heads video framing information is decoded, and such framing information and the recovered program clock are used to generate a video reference signal.
