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.

A method of decompressing color video data in a video information communication system utilizing a plurality of digitized signals having a portion thereof representing run length and a portion of representing color of at least a portion of a plurality of pixels in a plurality of scan lines of a vide

A method of decompressing color video data in a video information communication system utilizing a plurality of digitized signals having a portion thereof representing run length and a portion of representing color of at least a portion of a plurality of pixels in a plurality of scan lines of a video picture frame, said digitized signals being of a first digital word size, said run length portion of said digitized signal being of a second digital word size, said color portion of said digitized signal being of a third digital word size, comprising the steps of: (a) storing said run length portion and said color portion as an array in a memory means of run length data and color component data representing said plurality of pixels in said plurality of scan line in said video picture frame; and (b) converting said color portion into three digital color component signals of fourth, fifth, and sixth digital word sizes, respectively; and (c) generating a color video display signal comprising said three color component data from said run length and associated color components for said scan lines of said picture frame for each pixel of said picture frame, by mapping the pixels represented in said run length according to the associated color components for said run length from a starting pixel for said run length to the end pixel of said run length, to the end of the portion of each scan line to be mapped, and interpolating a smooth color transition from one of the group consisting of an intermediate decision point and one said starting pixel to one of the group consisting of an intermediate decision point and one said end pixel.
