Title (EN) VIDEO CONFERENCING SUBSCRIPTION USING MULTIPLE BIT RATE STREAMS
(FR) ABONNEMENT À UNE VISIOCONFÉRENCE AU MOYEN DE MULTIPLES DÉBITS BINAIRES
Abstract:
(EN) Subscriptions in a video conference may be provided using multiple bit rate streams. A video conference server may receive video streams from each client in a video conference and may receive subscription requests from each client. The subscription requests may include requests to see video streams from specific other clients at a given resolution and/or frame rate. The video conference server may match up the received video streams with the subscription requests in order to send the subscribing clients their desired video streams. The server may also be able to request different versions of video streams from participants (e.g. different resolutions) and/or alter the video streams in order to better comply with the subscription request.
(FR) Selon l'invention, des abonnements à une visioconférence peuvent être attribués au moyen de multiples débits binaires. Un serveur de visioconférence peut recevoir des flux vidéo en provenance de chaque client dans une visioconférence et peut recevoir des demandes d'abonnement en provenance de chaque client. Les demandes d'abonnement peuvent comprendre des demandes pour voir des flux vidéo en provenance d'autres clients spécifiques à une résolution et/ou un taux de trame donné. Le serveur de visioconférence peut apparier les flux vidéo reçus et les demandes d'abonnement afin d'envoyer aux clients abonnés les flux vidéo désirés. Le serveur peut également demander différentes versions de flux vidéo en provenance des participants (par exemple, différentes résolutions) et/ou altérer les flux vidéo afin de répondre au mieux à la demande d'abonnement.
