Title
(EN) VIDEO MEMORY MANAGEMENT FOR MPEG VIDEO DECODE AND DISPLAY SYSTEM
(FR) GESTION DE MEMOIRE VIDEO POUR SYSTEME DE DECODAGE ET D'AFFICHAGE VIDEO
Abstract
(EN)
A system and method for decoding and displaying a video bitstream representing video images and displaying the video images. The present invention discloses a split memory manager design which is particularly adapted to display MPEG-2 format video images. In addition, the present invention discloses a novel way of managing the video memory used in a video decode and display system. Finally, an intraframe video data compression system and method is disclosed to complement the disclosed video decoding and displaying system.
(FR)
Système et procédé qui permettent de décoder et d'afficher un train de bits vidéo représentant et affichant des images vidéo. L'invention concerne notamment un concept de gestionnaire partagé de mémoire, qui convient notamment pour afficher les images vidéo en format MPEG-2. Elle concerne également une nouvelle façon de gérer la mémoire vidéo utilisée dans un système de décodage et d'affichage vidéo, ainsi qu'un système et un procédé de compression de données vidéo intratrame qui complètent le système de décodage et d'affichage de l'invention.
