Motion vector quantizing selection system

An image processing system that processes image data between a source of the image data and a port connectable to a transmission link for transmission of said image data to a remote location, said image data including a current block which is a block of image data currently under consideration, the current block occupying a position in a current frame of image data, and said image data including a previous frame which is the frame of image data immediately prior to the current frame, said image processing system comprising:

• source means for generating video image data in frame by frame sequence, said source means including means to generate a current frame and a previous frame;
• a memory connectable to said source means to receive said video image data therefrom in said frame by frame sequence, each frame of said frame by frame sequence being comprised of a plurality of blocks, said memory being operable to hold at least a current block and at least a portion of said previous frame;
• means connected to receive said video image data and operable for selecting a motion previous block which best matches the current block from the blocks of said previous frame;
• means connected to receive said motion previous block and said current block and operable for determining a motion residual between said current block and said motion previous block;
• means connected to receive said motion previous block and said motion residual and operable for determining a motion residual distance measurement based at least in part based on said motion residual;
• means connected to receive said video image data and to select a conditional previous block which is a block that occupies a position in said previous frame that corresponds to the position the current block;
• means connected to receive said current block and said conditional previous block and operable for determining a conditional update residual between said current block and said conditional previous block;
• means connected to receive said conditional update residual, said motion previous block and said conditional previous block, said means being operable for determining a conditional update distance measurement based at least in part on said conditional update residual;
• means connected to receive said current block and said motion previous block and operable for determining a current block distance measurement based at least in part on pixel values of said current block;
• a vector quantizer for performing vector quantization of video image data supplied to and for generating a vector quantized signal reflective of said current frame;
• means connected to receive said video image data and said conditional previous block, said means being operable for determining and providing conditional update indicating bits to indicate that said conditional previous block is acceptable for purposes of decoding at a remote location;
• arbiter means connected to receive said current block, said motion residual, said conditional update indicating bits, said arbiter being operable for selecting and supplying to said vector quantizer one of (1) said current block, (2) said motion residual, or (3) said conditional update indicating bits;
• and
• a port connected to the vector quantizer to receive and to supply to a remote decoder said vector quantized signals reflective of said current frame.
