Dans cet article, la méthode de contrôle du débit vidéo basée sur la qualité et les données transférées pour les services de conférence Web est proposée, visant à réduire les données transférées en supprimant la qualité excessive. Dans les services de conférence Web, le débit vidéo est généralement contrôlé en fonction des conditions du réseau (par exemple, gigue et taux de perte de paquets) pour améliorer la qualité des utilisateurs. Cependant, dans un tel contrôle, le débit binaire est excessivement élevé lorsque les conditions du réseau sont suffisamment élevées (par exemple, débit élevé et faible gigue), ce qui entraîne une augmentation du volume de données transférées. L'augmentation du volume de données transférées entraîne une augmentation des coûts opérationnels, tels que les coûts de réseau pour les fournisseurs de services. Pour résoudre ce problème, nous avons développé une méthode permettant de contrôler le débit vidéo de chaque utilisateur afin d'obtenir la qualité requise déterminée par le fournisseur de services. Cette méthode est implémentée dans un système de conférence Web réel et évaluée dans diverses conditions. Il a été démontré que le débit pouvait être contrôlé en fonction de la qualité requise afin de réduire le volume de données transférées.

Abstract: In this paper, the quality and transferred data based video bitrate control method for web-conferencing services is proposed, aiming to reduce transferred data by suppressing excessive quality. In web-conferencing services, the video bitrate is generally controlled in accordance with the network conditions (e.g., jitter and packet loss rate) to improve users' quality. However, in such a control, the bitrate is excessively high when the network conditions is sufficiently high (e.g., high throughput and low jitter), which causes an increased transferred data volume. The increased volume of data transferred leads to increased operational costs, such as network costs for service providers. To solve this problem, we developed a method to control the video bitrate of each user to achieve the required quality determined by the service provider. This method is implemented in an actual web-conferencing system and evaluated under various conditions. It was shown that the bitrate could be controlled in accordance with the required quality to reduce the transferred data volume.
