ABSTRACT OF THE DISCLOSURE The method and system of decompressing color video data for use in a video information communication system utilizes digitized run length and color informa- tion 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 digit- ized 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 three digital color components data are stored in an array in a memory to represent the pixels in the scan lines of the video picture frames and the color portion of the digitized signal is converted into three digital color components of fourth, fifth, and sixth digital word sizes. 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 which generates a series of converted digital color components representing individual pixels, which is then converted to analog form for display on a monitor.
