CA 2237690

A compressed video playback system which eliminates playback mode transition artifacts. Transitions between various playback modes are effected in such a manner that transition artifacts are eliminated by delaying playback mode transitions until appropriate frames of data are detected for propagation to the compressed video decoder. In addition, compressed video data retrieval methods are improved for supporting multispeed playback modes in both forward and reverse directions in an optimal manner.

Système de reproduction de données vidéo comprimées qui élimine les artéfacts de transition entre les différents modes de reproduction. Ces transitions sont effectuées de manière à éliminer les artéfacts en retardant les transitions entre les modes de reproduction jusqu'au moment où les trames appropriées de données sont détectées pour être transmises au décodeur de données vidéo comprimées. En outre, les procédés de recherche des données vidéo comprimées sont améliorés de façon à comporter des modes optimaux de reproduction à plusieurs vitesses, à la fois en lecture avant et en lecture arrière.
