A method and apparatus for dynamic quality adjustment of digital media based on changing streaming constraints is provided. A digital media server sends a digital media stream according to a set of streaming constraints to a requesting client. A client sends a request (400) over a control network to the digital media server indicating information of a particular type is no longer desired. In response to receiving the signal, the video server ceases transmission of that particular type of information (430) to the signaling client, thus relaxing streaming constraints (440). when a viewer signals that a particular type of information is not desired, that particular type of information is not transmitted to the client, which thereby reduces the streaming constraints on a video streaming service, and improved quality digital media information (450) may be sent to any client using the freed-up portion of the bandwidth previously allocated to the signaling client.
L'invention porte sur un procédé et un appareil d'affinement dynamique de la qualité de supports numériques reposant sur la modification des contraintes de flux. A cet effet, un serveur de supports numériques transmet à un client participant un flux d'informations de support numérique obéissant à des contraintes de flux; un client envoie sur un réseau de commande un message (400) adressé au serveur de supports numériques précisant qu'il ne désire plus une information d'un type particulier. En réponse, le serveur vidéo cesse de transmettre audit client ledit type d'information (430), ce qui réduit les contraintes de flux (440). Ainsi lorsqu'un téléspectateur signale ne pas vouloir recevoir un type donné d'information, elle ne lui est pas transmise ce qui diminue les contraintes de flux du service vidéo de transmission et on peut alors transmettre au client une information de support numérique de meilleure qualité en utilisant la partie libérée de largeur de bande préalablement attribuée au client participant.
