Abstract
A mode decision method for the motion-compensated three-branch HD-MAC system is described. The conventional mode decision method consists of a priori and a posteriori decisions. The correctness of the mode decision has a considerable influence on the picture quality at HD-MAC receivers. The conventional scheme, however, does not provide a good decision result. Thus, a new method by which the modes of blocks ca be determined more correctly is proposed. This method is based on frame-exchange and motion-compensated interpolation. The performance of this method is shown to be better than that of the conventional ones. >
