摘要：Method, system and computer program, for improving compressed imagechroma information. In one aspect of the invention, a kind of color video frequency imagefor red color component resolution ratio refers to the blue component color videofrequency image higher than resolution ratio. On the other hand including the use oflower or higher quantization parameter, for one or more chrominance channels (QP) andbrightness. It is to indicate that video image is conducive to image and encodes usinglogarithm on the other hand. On the other hand,Video image is indicated using more thantwo chrominance channel.
