Cet article présente une technique d'estimation de mouvement (ME) efficace en mémoire pour la compression vidéo haute résolution. L’objectif principal est de réduire l’accès à la mémoire externe, notamment pour les ressources mémoire locales limitées. La réduction de l'accès à la mémoire peut permettre d'économiser avec succès la fameuse consommation d'énergie. La clé pour réduire les accès à la mémoire est basée sur un algorithme à polarisation centrale dans le sens où l'algorithme à polarisation centrale effectue la recherche de vecteur de mouvement (MV) avec le minimum de données de recherche. Tout en considérant la réutilisabilité des données, les approches proposées à double fenêtrage (DSW) utilisent le fenêtrage secondaire comme option selon les nécessités de recherche. Ce faisant, le chargement des fenêtres de recherche peut être allégé et donc réduire la bande passante de la mémoire externe requise. Les techniques proposées peuvent économiser jusqu'à 81 % de la bande passante de la mémoire externe et ne nécessitent que 135 Mo/s, alors que la dégradation de la qualité est inférieure à 0.2 dB pour les clips HDTV 720p codés à 8 Mbits/s.

Abstract: This paper presents a memory-efficient motion estimation (ME) technique for high-resolution video compression. The main objective is to reduce the external memory access, especially for limited local memory resource. The reduction of memory access can successfully save the notorious power consumption. The key to reduce the memory accesses is based on center-biased algorithm in that the center-biased algorithm performs the motion vector (MV) searching with the minimum search data. While considering the data reusability, the proposed dual-search-windowing (DSW) approaches use the secondary windowing as an option per searching necessity. By doing so, the loading of search windows can be alleviated and hence reduce the required external memory bandwidth. The proposed techniques can save up to 81% of external memory bandwidth and require only 135 MBytes/sec, while the quality degradation is less than 0.2 dB for 720 p HDTV clips coded at 8 Mbits/sec.
