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, the first encoding format being optimized for transmission to a client device over a current communication channel; transmitting the plurality of encoded video frames or portions to the client device over the communication channel; concurrently encoding the first plurality of video frames according to a second encoding format, the second encoding format having a relatively higher-quality compressed video and/or a lower compression ratio than the first encoding format; storing the first plurality of video frames encoded in the second encoding format on a storage device; and making the first plurality of video frames encoded in the second encoding format available to the client device and other client devices for playback of the video stream.
Linvention 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 optimisé pour la transmission vers un dispositif client sur un canal de communication courant; transmettre la pluralité de trames vidéo ou des parties de celles-ci codées au dispositif client sur ledit canal de communication; coder simultanément la première pluralité de trames vidéo selon un second format de codage présentant une qualité de compression vidéo relativement supérieure et/ou un taux de compression inférieur à ceux du premier format de codage; stocker dans un dispositif de stockage la première pluralité de trames vidéo codées selon le second format de codage et la mettre à la disposition du dispositif client ou d'autres dispositifs clients pour permettre la lecture du flux vidéo.
