Patent number: 11641447Abstract: A new real-time video communication device improves the clarity of shared screen by automatically adjusting the key frame's quantization parameter values. The adjustment depends on the underlying network's connection condition. When the connection bandwidth deteriorates, the key frame's quantization parameter value is further decreased on the value output from a standard H.264 encoder to derive a desirable quantization parameter value and thus achieve a desirable user experience of the shared screen. Moreover, the new real-time video communication device adjusts the frame rate of the shared screen based on the present quantization parameter value to achieve a more desirable user experience of the screen sharing.Type: GrantFiled: April 25, 2022Date of Patent: May 2, 2023Assignee: Agora Lab, Inc.Inventors: Jiang Li, Zheyuan Zhang
