Patent

CA 2656453

The invention relates to a method for determining operating parameters, such as compression rate and/or protection rate, for a multimedia data transmission channel, characterised in that it includes at least one step consisting in determining several sensitivity values for pairs of source fixed flow values and the desired compression rate, a step consisting in comparing the different values obtained for one operating point of the fixed channel and a step consisting in selecting the optimal sensitivity value, said sensitivity value being defined taking account of the desired source flow and the compression rate.

Procédé permettant de déterminer des paramètres de fonctionnement, tels que le taux de compression et/ou le taux de protection pour un canal de transmission de données multimédia caractérisé en ce qu'il comporte au moins une étape au cours de laquelle on détermine plusieurs valeurs de sensibilité pour des couples de valeurs débit fixé de la source, taux de compression souhaité, et une étape où l'on compare entre elles les différentes valeurs obtenues pour un point de fonctionnement du canal fixé, une étape où l'on sélectionne la valeur de sensibilité optimale, la valeur de sensibilité étant définie en tenant compte du débit de source souhaité et du taux de compression.
