Motion palette coding for video compression

Video encoding relies on the reduction of both spatial and temporal redundancies to achieve low bit rates. The total channel bandwidth is generally divided between motion and residue information. The overall bit rate can be controlled by changing the quantization setting of the residue coder, but no simple control mechanism exists for the motion coder. This paper introduces a method of encoding motion vectors, which provides a simple mechanism of controlling the motion side information bit rate. By being able to control both the motion and residue information bit rates: the coder is capable of dividing the available bandwidth between the two channels in an optimal way. This results in a more efficient coding system.
