Abstract:
1. A method for representing a motion for two blocks, comprising the steps of: (A) exchanging a group with a memory, said group comprising a parameter and up to two of a plurality of motion vectors, said parameter having (i) a first value which indicates that both of said blocks use an intra prediction (ii) a second value which indicates that both of said blocks use a list 0 prediction, (iii) a third value which indicates that both of said blocks use a list 1 prediction and (iv) a fourth value which indicates that both of said blocks use a bidirectional prediction in which a first of said blocks uses both of said two motion vectors and a second of said blocks uses both of said two motion vector and (2) said exchanging includes at least one of reading from said memory and writing to said memory; and (B) representing said motion for said two blocks with said group, wherein said two blocks comprise two 4×4 blocks within a single 8×8 quadrant of a macroblock coded using a macroblock adaptive field/frame coding.
