MPEG-2/MPEG-4/H.264

Les extensions de la norme MPEG-2 pour inclure le H.264 comme type de flux élémentaire (ES) complémentaire d’un flux de transport (TS) MPEG-2 rendent accessible et attractif le H.264 pour les diffuseurs et les opérateurs de réseau. La transition constitue un défi pour les équipementiers qui créent des variantes du H.264, car malgré le fait que le H.264 assure une compression deux fois plus efficace que le format MPEG-2, la complexité de traitement est elle aussi deux fois supérieure. Tektronix peut contribuer à l’utilisation d’une solution H.264 de bout en bout, avec 3 phases principales : conception, déploiement et gestion.

La technologie de flux de transport MPEG-2 continue à bien fonctionner dans de nombreuses applications, y compris les codeurs de compression H.264 ou MPEG-4 nouvelle génération. La vérification de la conception et le débogage et l’analyse peuvent impliquer le test du flux de transport MPEG-2 ainsi que l’évaluation des données du flux élémentaire.
