Abstract
La présente invention concerne un procédé d'adaptation dynamique du codage avec pertes d'un flux audio et/ou vidéo (112) transmis par un premier dispositif (101) vers un dispositif distant (102), ledit procédé comprenant les étapes suivantes: le dispositif distant (102) reçoit et décode ledit flux (112), dit flux entrant, et transmet un flux sortant (111) comportant au moins un indicateur relatif à un état dudit dispositif distant (102) qui est modifié par l'exécution du décodage du flux entrant (112) ; le premier dispositif (101) reçoit le flux sortant (111), en extrait ledit au moins un indicateur, et adapte le codage du flux entrant (112) en fonction dudit au moins un indicateur extrait. Le procédé s'applique notamment aux vidéoconférences opérées à partir de terminaux autonomes en énergie aux fins de préserver la durée de fonctionnement de ces terminaux
