视频通信系统以及基于长参考帧的视频传输方法
By employing long reference frame technology in video communication systems, the control unit buffers IDR frames and sends long reference frames, thus solving the problems of computational resource and bandwidth consumption at the sending end, ensuring stable image quality, and improving the stability of video communication systems.

AI Technical Summary
In existing technologies, when the receiving end joins the conference for the first time or when there is severe packet loss and the video cannot be recovered, the sending end consumes high computing resources and has a large uplink bandwidth usage, resulting in a decrease in image quality and affecting the communication quality of other participants.
By employing long reference frame technology, the control unit caches the most recently encoded IDR frame and sends a long reference frame to replace the IDR frame when a request is received from the receiver, thereby reducing the computational load and uplink bandwidth pressure on the transmitter and ensuring stable image quality.
It effectively reduces the computational load on the sending end and the uplink network bandwidth pressure, maintains stable image quality, reduces the probability of congestion and packet loss, and improves the stability of the video communication system.
