Abstract
Provided are a color video scalability encoding and decoding method and a device thereof. The color video scalability encoding method includes encoding a chrominance image block of an enhancement layer by using lower layer information. In the encoding a chrominance image block, a color coded block pattern value is generated according to a pattern of quantization coefficients of a residual chrominance Image block chrominance image block generated using the lower layer information.
