Nous présentons un format vidéo MPEG étendu pour une mise à l'échelle dynamique de tension (DVS) efficace. La technique DVS a fait l'objet de nombreuses recherches, mais la variation du temps d'exécution d'une tâche périodique (c'est-à-dire le décodage MPEG) reste un défi à relever. Contrairement aux travaux précédents, nous nous concentrons sur les données (flux vidéo) plutôt que sur le code d'exécution pour surmonter cette limitation. Le format vidéo proposé fournit les coûts de décodage des images pour aider à prédire avec précision leurs temps d'exécution sur les machines clientes. Les résultats expérimentaux montrent que le format étendu n'augmente la taille des données que de moins de 1 % en ajoutant environ 10 bits représentant le coût de décodage de chaque trame. De plus, une technique DVS ajustée au format proposé atteint 90 % d'efficacité par rapport au cas Oracle, tout en gardant le temps d'exécution de la technique négligeable.

Abstract: We present an extended MPEG video format for efficient Dynamic Voltage Scaling (DVS). DVS technique has been widely researched, but the execution time variation of a periodic task (i.e. MPEG decoding) is still a challenge to be tackled. Unlike previous works, we focus on the data (video stream) rather than the execution code to overcome such limitation. The proposed video format provides the decoding costs of frames to help the precise prediction of their execution times at client machines. The experimental results show that the extended format only increases the data size less than 1% by adding about 10 bits representing the decoding cost of each frame. Also, a DVS technique adjusted for the proposed format achieves 90% of efficiency compared to the oracle case, while keeping the run time overhead of the technique negligible.
