  • Method for transmitting compressed video data and apparatus for performing the same
    Patent number: 5805826
    Abstract: An apparatus for transmitting compressed video data includes a data interfacing circuit, a data connecting circuit, a decompression unit, and a CPU. The data interfacing circuit receives and stores compressed video data, generates a first control signal in response to receipt of the compressed video data, identifies an address bus and a data bus used for transmitting the compressed video data and then generates a hold permission signal in response to receipt of a hold request signal. The data interfacing circuit also provides output of the compressed video data in response to receipt of an address control signal. The decompression unit generates a data request signal to request input of said compressed video data. The decompression unit receives the compressed video data from the data interfacing circuit and decompresses the compressed video data to generate a motion picture in response to receipt of a data permission signal.
