Title
(EN) METHOD AND SYSTEM FOR CONTROLLING A PROCESSING OF VIDEO DATA
(FR) PROCEDE ET SYSTEME DE CONTROLE DU TRAITEMENT DE DONNEES VIDEO
Abstract
(EN) A method and system for controlling a processing of video data such that said video data may be transmitted over a connection in a communication network, where said connection employs a plurality of protocol layers. The processing of video data for transmission is performed at a first layer. A value or values of one or more transmission condition parameters indicative of transmission conditions in the network are acquired, where these transmission condition parameters are specific for a second layer provided lower than said first layer. Then one or more values of one or more video control parameters usable at said first layer are derived from said value of said at least one transmission condition parameter and the processing of video data is performed in accordance with the derived one or more values.
(FR) L'invention concerne un procédé et un système de contrôle du traitement de données vidéo, de manière à ce que lesdites données vidéo soient transmises via une connexion dans un réseau de communication, où ladite connexion utilise plusieurs couches de protocoles. Le traitement des données vidéo destinées à être transmises est réalisé au niveau d'une première couche. Une valeur ou des valeurs d'un ou plusieurs paramètres de conditions de transmission(s) indiquant les conditions de transmission au réseau sont acquises, lorsque ces paramètres de conditions de transmission sont spécifiques à une seconde couche inférieure à ladite première couche. Ensuite, une ou plusieurs valeur(s) d'un ou plusieurs paramètre(s) de conditions de transmission utilisables au niveau de la première couche sont dérivées de ladite valeur d'au moins un paramètre de conditions de transmission et le traitement de données vidéo est réalisé conformément à cette ou à ces valeurs dérivées.
