Title (EN) METHOD AND DEVICE FOR GLOBAL BITRATE CONTROL OF A PLURALITY OF ENCODERS
(FR) PROCEDE ET DISPOSITIF DE REGULATION DU DEBIT BINAIRE GLOBAL D'UNE PLURALITE DE CODEURS
Abstract:
(EN) Control method for distributing, under the control of a control unit (100), a constant global bitrate among several, simultaneously operating encoders (10a, 10b, ..., 10i, ..., 10n) in order that a quality which is substantially equivalent for each of these encoders is obtained at any instant, irrespective of the complexity of the pictures determined for each encoder by circuits (30a, 30b, ..., 30n). Application: encoding in accordance with the MPEG2 standard.
(FR) Cette invention concerne un procédé de régulation permettant de répartir, sous la commande d'une unité de commande (100), un débit binaire global constant parmi plusieurs codeurs fonctionnant simultanément (10a, 10b, ...,10i, ...,10n) de façon à obtenir, à tout instant, une qualité sensiblement équivalente associée à chacun des codeurs, quelle que soit la complexité des images déterminée pour chacun des codeurs par des circuits (30a, 30b, .. , 30n). Application: codage selon la norme MPEG2.
