Abstract:
A packetizing method for packetizing a bit stream in a packetizing apparatus. The packetizing 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 packetizing, in a packetizing unit in the packetizing apparatus, the bit stream and generating a packetized stream.
