Abstract
The method and system of decompressing color video data for use in a video information communication system utilizes digitized run length and color information to represent the pixels in the scan lines of a video picture frame. The digitized signals are of a first digital word size, the run length portion of the digitized signal is of a second digital word size and the color portion of the digitized signal is of a third digital word size. The run length portion and the color portion are stored in an array in a memory to represent the pixels in the scan lines of the video picture frame. The memory consists of a pingpong A buffer memory and a pingpong B buffer memory, from which the run length and color information is transferred to a display drawing engine. The color portion of the digitized signal is converted into three digital color components of fourth, fifth, and sixth digital word sizes as a series of digitized signals representing individual pixels, which is then converted in a digital to analog converter to analog format for display on monitor.
