International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California<br>Compressed video is necessary for a variety of telemetry requirements. A large number of competing video compression algorithms exist. This paper compares the ability of these algorithms to meet criteria which are of interest for telemetry applications. Included are: quality, compression, noise susceptibility, motion performance and latency. The algorithms are divided into those which employ inter-frame compression and those which employ intra-frame com

The increasing density offered by Field Programmable Gate Arrays(FPGA), coupled with their short design cycle, has made them a popular choice for implementing a wide range of algorithms and complete systems. In this thesis the implementation of video compression algorithms on FPGAs is studied. Two areas are specifically focused on; the integration of a video encoder into a complete system and the power consumption of FPGA based video encoders. Two FPGA based video compression systems are described, one which targets surveillance applications and one which targets video conferencing application

We show how the use of a small amount of buffering and GOP grouping can significantly reduce the effect of the short-term variation. By introducing a number of bandwidth renegotiation techniques, which can be applied to MPEG video streams in general, we are able to reduce the effect of long-term variation. These techniques include those that need the a priori knowledge of frame sizes as well as one that can renegotiate dynamically. A costing algorithm has also been introduce

CE MEMOIRE TRAITE DE L'INTEGRATION DES TECHNIQUES DE CODAGE VIDEO PAR MAILLAGES DANS DES SCHEMAS DE CODAGE ET DE LA MISE EN ADEQUATION DE CES ALGORITHMES AVEC UNE ARCHITECTURE MULTI-PROCESSEURS PENTIUM. L'AUGMENTATION CROISSANTE DES CAPACITES DES RESEAUX S'AVERE INSUFFISANTE, FACE A LA MULTIPLICATION DES DONNEES MISES EN CIRCULATION. DE CE FAIT, POUR L'ENSEMBLE DES MEDIA ET EN PARTICULIER POUR LA VIDEO, LES TRES BAS DEBITS RESTENT TOUJOURS UN OBJECTIF MAJEUR. AFIN D'ATTEINDRE CEUX-CI, LES ALGORITHMES DE CODAGE D'IMAGES ET DE VIDEO BASES MAILLAGES SEMBLENT PERTINENTS. CEPENDANT UNE SOLUTION DE

Abstract:
Le codage de sources distribuées est une technique permettant de compresser plusieurs sources corrélées sans aucune coopération entre les encodeurs, et sans perte de débit si leur décodage s'effectue conjointement. Fort de ce principe, le codage de vidéo distribué exploite la corrélation entre les images successives d'une vidéo, en simplifiant au maximum l'encodeur et en laissant le décodeur exploiter la corrélation. Parmi les contributions de cette thèse, nous nous intéressons dans une première partie au codage asymétrique de sources binaires dont la distribution n'est pas uniforme, puis au c
