Title
(EN) INCREASING VIDEO BIT RATES WHILE MAINTAINING VIDEO QUALITY
(FR) AUGMENTATION DE DÉBITS BINAIRES VIDÉO AVEC MAINTIEN DE QUALITÉ VIDÉO
Abstract
(EN)
Systems, methods, and software technology for optimizing the streaming video to end points while maintaining low latency. In an implementation, a streaming service receives video data for distribution to a plurality of end points. For each end point, the service streams the video data at a given bit rate to the end point. While the video is being streamed, the service sends test data to the end point at an additional bit rate. The service also increases the additional bit rate of the test data until a threshold decline in quality of the video data occurs or until a total bit rate of the video data and the test data reaches a next available bit rate for the video data. The service conditionally switches from the given bit rate to the next available bit rate if the total bit rate has reached the next available bit rate.

L'invention concerne des systèmes, des procédés et une technologie logicielle pour optimiser la diffusion en continu de vidéos vers des points d'extrémité tout en maintenant une faible latence. Dans un mode de réalisation, un service de diffusion en continu reçoit des données vidéo en vue d'une distribution à une pluralité de points d'extrémité. Pour chaque point d'extrémité, le service diffuse les données vidéo à un débit binaire donné vers le point d'extrémité. Pendant que la vidéo est diffusée en continu, le service envoie des données de test au point d'extrémité à un débit binaire supplémentaire. Le service augmente également le débit binaire supplémentaire des données de test jusqu'à ce qu'un déclin seuil de la qualité des données vidéo se produise ou jusqu'à ce qu'un débit binaire total des données vidéo et des données de test atteigne un débit binaire disponible suivant pour les données vidéo. Le service passe de manière conditionnelle du débit binaire donné au débit binaire disponible suivant si le débit binaire total a atteint le débit binaire disponible suivant.
