CA 2111021
In an encoding and decoding method of color signal components of picture signals having a plurality of resolutions, an encoding system and a decoding system can be obtained color pictures with higher definition, so that color different signals in a format of the macroblock of 4:4:4 are encoded by a circuit 102. These color difference signals with the highest definition are down-sampled by a down sampling circuit 103 and then encoded by a circuit 101. These color difference signals with intermediate definition are further down-sampled by a down sampling circuit 104 to produce the color difference signals with the lowest definition. These color difference signals in a format of the macroblock of 4:2:0 are supplied to and encoded by a circuit 100. Data output from the circuits 100, 101, and 102 are composed by a combining circuit 105 and transmitted.
