Abstract
Video signals are encoded and decoded using a set of quantization tables that is generated from a base matrix and a scale matrix, which are both explicitly encoded into the encoded video bitstream. The sets of quantization tables may be changed as often as needed as long as the new base and scale matrices are explicitly encoding into the bitstream.
