  • MPEG-2 multiplexer for ATM network adaptation
    Patent number: 6038232
    Abstract: A moving picture expert group (MPEG)-2 transport stream (TS) multiplexer for an asynchronous transfer mode (ATM) network adaptation. The MPEG-2 multiplexer for ATM network adaption includes media and timer processor, TS packet multiplex controller, buffer, and ATM network adaptation processor. The media and timer processor is initialized by an external clock and reset signal, receives signals DATA, WRITE and each module selection signal CHPSEL from an external processor to store the header of each TS packet, generates a TS packet by receiving data from a video/audio encoder, and thereby drives a timer with the clock signals. The TS packet multiplex controller multiplexes each TS packet provided from the media and timer processor or outputs an input/output controlling signal to multiplex. The buffer buffers TS-PDU transmitted from the TS packet multiplex controller.
