Une approche d'un système de décodage MPEG avec une capacité de mémoire réduite sera présentée. Cette méthode repose sur la technique simple du DPCM unidimensionnel pour recompresser le macrobloc (Mo) reconstruit avant d'être stocké dans la mémoire de trame. Les résultats de la simulation suggèrent que la qualité de l'image est subjectivement acceptable lorsque l'on utilise environ la moitié de la taille de mémoire requise par celle d'un décodeur conventionnel. La dégradation du rapport signal sur bruit introduite par cette méthode de compression variait de 0.1 dB à 0.7 dB pour les séquences de test standard MPEG MP@ML à 4 Mbps. Cette technique peut être mise en œuvre pour obtenir un décodeur MPEG rentable.

Abstract: An approach to an MPEG decoding system with reduced memory capacity will be presented. This method relies on the simple technique of one-dimensional DPCM to recompress reconstructed Macro Block (MB) prior to being stored on frame memory. Simulation results suggest that image quality is subjectively acceptable when using approximately one-half of the memory size required by that of conventional decoder. The degradation in the signal-to-noise ratio introduced by this compression method ranged from 0.1 dB to 0.7 dB for MPEG MP@ML standard test sequences at 4 Mbps. This technique can be implemented to achieve a cost effective MPEG decoder.
