Method and system for multiplexing and demultiplexing video signals for graphic display monitors in computer systems

摘要

A computer graphics and display system is provided, comprising (i) a graphics system for outputting a first plurality of digital color signals; (ii) a first digital-to-analog converter (DAC) for converting the first plurality of digital color signals into a second plurality of analog color signals, the second plurality being less in number than the first plurality; (iii) a first analog-to-digital converter (ADC) for reconverting the second plurality of analog color signals back to the first plurality of digital color signals; and (iv) an LCD display device for receiving the reconverted first plurality of digital color signals. The first and second DACs and the first and second ADCs are implemented within the same integrated circuit (IC) chip. The first plurality of digital color signals comprises red, blue and green even pixels and red, blue and green odd pixels. Each color for both even and odd pixels is encoded onto a single pair of the first DACs by interleaving same color pixels onto the single pair.
