摘要:
A multiplexing method for multiplexing a bit stream in a multiplexing apparatus. The method includes encoding, in an encoding unit in the multiplexing apparatus, a chroma component of image data using a chroma quantization parameter calculated on the basis of a luma quantization parameter weighted by an addition operation that adds a weight parameter and generating the bit stream. The method further includes multiplexing, in an multiplexing unit in the multiplexing apparatus, the bit stream and generating a system stream.
