ABSTRACT:
A digital video display system which includes a digital data output unit, such as a computer system, and a display unit coupled to receive digital data from the digital data output unit. In order to reduce the amount of data transferred on a signal line connecting the digital data output unit and the display unit, the digital data is transferred as a video drawing command. After the display unit receives this video drawing command, a drawing processing circuit within the display unit generates digital video data and a synchronizing signal based on the video drawing command. This digital video data is then stored, and subsequently converted to an analog video signal for display. Alternative embodiments are also provided which include audio processing, arrangements for simultaneously displaying multiple pictures, and arrangements for compression and decompression of the video data.
