Tech Paper 2022: This paper proposes an ultra-low bitrate video conferencing system using flexible avatar-based access patterns to save bandwidth, improve quality, and protect privacy.
Abstract
The demand for remote work and online entertainment is surging annually, placing heightened challenge on bandwidth usage and experience quality of applications such as video conferencing. Video codecs in traditional video conferencing systems typically utilize a block-based hybrid coding architecture, which often have sub-optimal rate distortion performance and computational resource consumption in these scenarios. In addition, in low bit rate scenarios due to low bandwidth networks, traditional codecs may lead to a disastrous experience.
