Abstract
A video compression/decompression procedure that provides a reliable, low bit video bit stream with some color features over relatively low bandwidth wireless networks. The procedure provides some pleasing color features in a video bit stream without needing a large bandwidth network like those needed for example for a MPEG 4 bit stream. The procedure provides the color features by using a bi-level Y luminance component and a number of UV chrominance combinations. The bi-level Y-component outlines the features of the image, while the UV-combinations describe the basic color information of the image.
