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 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 frame; 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.
