Paper Abstract

2D-signal processing techniques for interframe hybrid coders with motion compensating prediction are investigated. "Equivalent" 2D-filters and "equivalent" coder structures are proposed to improve the subjective quality of moving pictures encoded at about 64 to m x 384 kbit/s (m = 1, 2, ..., 5). An optimum predictor is derived and it is concluded that this solution is quite close to the concept of equivalent filters. The complete coding scheme is described.
