Abstract : Multi-frame motion-compensated prediction can achieve high prediction gain performance with additional frame buffer memory requirement. For mobile-telephony applications which uses mobile processor, reducing the memory requirement is very important. In this paper, we propose an efficient memory management control scheme which reduces memory requirement for storing references at the decoder side. Our proposed technique is a frame-based memory management scheme which discards the reference frames that are least important in terms of prediction gain performance. The optimal solution for this problem requires checking all the penalty increases for all the combination of discarded reference frames, and therefore we propose a greedy search that checks a subset of reference frame combinations.
