CA 2756299

A computer-implemented system and method are described for performing video compression. For example, a method according to one embodiment comprises: encoding a plurality of video frames or portions thereof according to a first encoding format; transmitting the plurality of encoded video frames or portions to a client device; receiving feedback information from the client device, the feedback information usable to determine whether data contained in the video frames or portions has not been successfully received and/or decoded; in response to detecting that a video frame or portion thereof has not been successfully received and/or decoded, encoding a video frame or portion thereof according to a second encoding format; and transmitting the video frames or portions thereof to the client device.

L'invention concerne un système informatisé et un procédé de mise en oeuvre d'une compression vidéo. Par exemple, un procédé, selon un mode de réalisation de l'invention, consiste à: coder une pluralité de trames vidéo ou des parties de celles-ci selon un premier format de codage; transmettre la pluralité de trames vidéo ou des parties de celles-ci codées à un dispositif client; recevoir du dispositif client des informations en retour utilisables pour déterminer si des données contenues dans les trames vidéo ou des parties de celles-ci n'ont pas été correctement reçues et/ou décodées; s'il est détecté qu'une trame vidéo ou une partie de celle-ci n'a pas été correctement reçue et/ou décodée, coder alors une nouvelle trame vidéo ou une partie de celle-ci selon un second format de codage; et transmettre les trames vidéo ou des parties de celles-ci au dispositif client.
