Dalam kertas kerja ini, kaedah kawalan kadar bit video berasaskan kualiti dan data yang dipindahkan untuk perkhidmatan persidangan web dicadangkan, bertujuan untuk mengurangkan data yang dipindahkan dengan menekan kualiti yang berlebihan. Dalam perkhidmatan persidangan web, kadar bit video secara amnya dikawal mengikut keadaan rangkaian (cth, jitter dan kadar kehilangan paket) untuk meningkatkan kualiti pengguna. Walau bagaimanapun, dalam kawalan sedemikian, kadar bit adalah terlalu tinggi apabila keadaan rangkaian cukup tinggi (cth, daya pemprosesan tinggi dan jitter rendah), yang menyebabkan volum data dipindahkan meningkat. Peningkatan volum data yang dipindahkan membawa kepada peningkatan kos operasi, seperti kos rangkaian untuk penyedia perkhidmatan. Untuk menyelesaikan masalah ini, kami membangunkan kaedah untuk mengawal kadar bit video setiap pengguna untuk mencapai kualiti yang diperlukan yang ditentukan oleh pembekal perkhidmatan. Kaedah ini dilaksanakan dalam sistem persidangan web sebenar dan dinilai dalam pelbagai keadaan. Telah ditunjukkan bahawa kadar bit boleh dikawal mengikut kualiti yang diperlukan untuk mengurangkan volum data yang dipindahkan.

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.
