ABSTRACT:
A hybrid coder, for performing interframe video encoding which combines the advantages of both the interfield and the interframe codings for low bit-rate video transmission; the pel elements of a differential block from a subtracter is rearranged; the complexity of a present input block and the horizontal motion vector thereof are estimated; and, then, one of the differential block and the rearranged block is subjected to a two-dimensional transform according to the complexity and the horizontal motion vector.
