Macroblock Coding
+------+------+-------+--------+-----+----+----+--------+ | ADDR | TYPE | QUANT | VECTOR | CBP | b0 | b1 | ... B5 | +------+------+-------+--------+-----+----+----+--------+- ADDR .... address of block in image
- TYPE .... identifies type of macroblock (intra-frame, inter frame, bi-directional inter frame)
- QUANT ... quantization value to vary quantization
- VECTOR... motion vector
- CBP...... Coded Block Pattern – this is bit mask indicating for which blocks coefficients are present.
- the blocks (4 Y, 1 Cr, 1 Cb)
