Abstract

The invention discloses a processing method for error correction requests from video client-sides in a video conference system. The processing method includes the following steps: allocating a weighted value for each video client-side; determining two or more threshold values according to the number of the video client-sides and the allocated weighted values; determining a plurality of response time periods; and receiving the error correction requests from the video client-sides, determining threshold value ranges where the video client-sides are located, and processing the error correction requests from the video client-sides according to the response time periods corresponding to the determined threshold value ranges. The processing method for the error correction requests can also be applied to a video server used for processing the error correction requests, and the video conference system provided with the video server.

Description

technical field [0001] The present invention relates to the field of video communication, in particular to a method for communicating in a video conference system including a video server and a video client, as well as the corresponding video server and video conference system. Background technique [0002] Videoconferencing enables remote parties to meet face-to-face using audio and video signals. A video conferencing system may include one or more video conferencing endpoints and a video server. Participants in a video conference interact with participants in other locations through a video conference endpoint. A video conference endpoint may be a video terminal on a network capable of real-time, two-way audio / video / data communication with other video terminals and / or video servers. Of course, video conferencing endpoints may provide voice only, voice and video, or voice, data and video communications, and so on. Videoconferencing endpoints typically include a display u...
