For example, a user started watching 720p video, after the connection deteriorated for a few seconds, the server will switch the video quality from 720p to 480p, if the connection is still bad enough and cannot handle 480p, the quality will deteriorate to 240 and finally up to 144 rub.

Abstract

L'invention se rapporte au domaine de la transmission d'images, et notamment au domaine de la transmission d'images vidéo sur le réseau Internet. Ce procédé d'adaptation de transmission d'image vidéo à la qualité de connexion au réseau Internet est caractérisé en ce que la transmission vers l'utilisateur du réseau Internet de l'image vidéo s'adapte automatiquement sans participation de l'utilisateur à l'état de connexion d'un utilisateur donné au réseau Internet dans des cas de coupure (interférences) et/ou de diminution (augmentation) des capacités de transmission de la connexion au réseau Internet; le procédé se distingue en ce que l'adaptation de l'image vidéo à l'état de connexion au réseau se fait en diminuant (augmentant) la taille de la trame de l'image vidéo à transmettre lors de la coupure (interférences) et/ou de la diminution (augmentation) des capacités de transmission de la connexion au réseau Internet; la diminution de la taille de la trame de l'image vidéo à transmettre se fait jusqu'à la transmission du son uniquement et la coupure complète de la transmission.
