Embodiment Construction

[0028] In the present invention, multiple pictures are synthesized into one video stream, and the video stream is multi-picture video (including a special case of single picture), and the multi-picture video is displayed on the display. The terminals participating in the communication can see the video of multiple call terminals at the same time, and can automatically identify the speaking end according to the sound conditions of each terminal and display the speaking end in a special way, so as to improve the user's video experience, enhance the user's communication effect, and improve the use of the system value.

[0029] Such as figure 1 Shown, method of the present invention comprises the steps:

[0030] Step 110, the terminal participating in the communication establishes a connection with the MCU providing the multipoint communication service.

[0031] Wherein, one of ITU-TH.323, ITU-TH.320, and IETFSIP protocols can be used to establish a connection between the termin...

Abstract

The present invention relates to a video conference system, and particularly to a multi-picture-mixing method of video conference system and a device thereof. The method comprises the following steps in turn: a. establishing connection between the video conference terminals and a multi-point control unit, transmitting the local audio and video flow and sound condition to the multi-point control unit; b. determining which terminal is a speaking terminal by the multi-point control unit according to sound information, combining the picture of speaking terminal with the pictures of other terminals to one output video flow, and executing special displaying for the picture of speaking terminal; c. transmitting the mixed output video flow to each terminal of video conference by the multi-point control unit; and d. displaying the received output video flow on the display by each terminal of video conference. The invention settles the problem that the sub-screen of each terminal can not determine and display the speaking end in the prior video conference system. The using of conference participators is facilitated and the actual operation effect of system is improved.

Description

technical field [0001] The invention relates to a video conferencing system, in particular to a multi-picture mixing method and device for the video conferencing system. Background technique [0002] A video conferencing system is a multimedia communication system that supports voice, video, and data communications, and generally includes a video conferencing terminal, a Multipoint Control Unit (MCU for short), and other audio and video acquisition and output devices. [0003] The video conferencing systems currently on the market generally conform to the ITU-TH.320 (International Telecommunication Union Telecommunication Standard H.320) or ITU-TH.323 standard, and there are also systems conforming to the IETFSIP (Internet Engineering Task Force Session Initiation Protocol) standard. [0004] The basic functions of each part in a common video conferencing system are as follows: [0005] A video conference terminal is a device used by a user. The terminal contains audio and...
