  • Patent number: 5948091
    Abstract: A digital display device interface for a host system (12) and its display device (14) and peripherals. The interface has separate logical and physical levels, thereby making the interface independent of any hardware configuration or connector. The initialization logic level allows dynamic configuration of the system upon power up or initialization. The display data level (30) controls the video data sent for display in a continuous, full bandwidth data stream. The I/O data level (32) controls communications between peripheral devices (18a . . . 18x) connected to the display device (14) and the system (12).
