Abstract

L'invention concerne un dispositif de jeu (10) qui peut transmettre des données AV de jeu à un terminal de réception (20) en réglant de manière adaptative le protocole de communication. Le réglage du protocole est effectué en fonction de l'état de la scène dans les données AV et l'environnement de propagation comme notamment le taux d'erreur de transmission. Par exemple, l'utilisation d'un UDP pour une scène de jeu nécessitant un caractère temps réel élevé et d'un TCP pour une scène de jeu nécessitant un caractère temps réel bas, permet de transférer de façon efficace les données AV au terminal de réception (20) sans nuire à la caractéristique de jeu.
