1. A system for decompressing video data streams and for providing continuous video data output, the system comprising:

  • an input switch coupled to a plurality of compressed video data input lines, the switch capable of selecting input lines and capable of controlling the video data flow rate of the selected input lines;

    a plurality of decompression modules coupled to the input switch for decompressing compressed video data received from the input switch and storing decompressed video data;

    an output switch coupled to the decompression modules, the output switch coupling only one of the decompression modules to an output bus at any time; and

    a controller coupled to the input switch, the decompression modules, and the output switch for selecting which decompression module will receive video data at a first predefined rate, the decompression module receiving video data at the first predefined rate also being coupled to the output bus by the output switch.
