Video conference control system and control method

Abstract

The invention discloses a video conference control system and method. The method comprises the following steps: terminals initiating a conference, and arranging configuration information of each participating terminal in the conference; a video conference manager receiving the configuration information and forwarding to a video conference scheduler after storage; the video conference scheduler establishing connection with each terminal according to the configuration information; the terminals obtaining audio data, according to a sound energy attenuation model and a maximum likelihood estimation method, constructing a likelihood function, calculating an average optimal position by use of the likelihood function, positioning the position of a speaker through combining the average optimal position with historical data, controlling a camera to find a view of the positioned position, extracting attributes of obtained video streams, and uploading the video streams, the video stream attributes and audio streams which are obtained by the terminals to the video conference scheduler; and the video conference scheduler generating sequences sent to the video streams of the connected terminals according to the configuration information, the video streams, the video stream attributes and the audio streams.

Description

technical field [0001] The invention relates to a video conference control system and a control method thereof, belonging to the communication field. Background technique [0002] Video conferencing is a common means of communication in modern communication. Through video conferencing, participants can realize remote voice and video communication, which is very convenient and fast. [0003] The remote video conference control system enables people located in different places to communicate and collaborate remotely face to face, so that the participants have an enhanced meeting experience. The existing video conferencing control system usually includes multiple terminals, and a server that manages and controls these terminals. Multiple terminals are connected to the server and send their respective audio / video data to the server. The server performs audio processing according to the actual situation. / Mixing and processing of video data, and then send these data to each te...

Problems solved by technology

[0004] However, there are some problems in the existing video conference control: firstly, the existing control system usually adopts the form of manually switching pictures to highlight the speaker, and there are problems of manual operation error and delay due to manual switching; In some control systems, each initiation of a conference requires the user to configure a complex terminal configuration information table, such as setting the type of participants, basic information of the terminal, etc., which makes the initiation of the conference too cumbersome
