Problems solved by technology

Therefore, simply relying on the existing remote camera control function of the multi-point video terminal itself is far from meeting the needs of the new generation of video conferencing. There is an urgent need for a method that can use the existing remote camera control function to realize the above multiple autonomous control functions on the MCU. Methods

Embodiment Construction

[0087] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0088] In this embodiment, it is stipulated that the chairperson of the meeting is the chairman and enters the video screen, the other screens in the video screen except the chairman screen are the selected audience, and all the participants who do not enter the screen are the general audience. In the single split screen mode, what the general audience sees is the screen of the chairman terminal, and what the chairman sees is the screen of the selected audience terminal; in the multi-split mode, what all participants see is the chairman terminal and the selected audience terminal screen.

[0089] According to the multimedia communication standard based on packet switching (ITU-T H.323 Annex Q) and the remote camera control protocol (ITU-TH.281), the MCU...

Abstract

In currently-used video terminals, only few products can support the remote video camera control function or the function of requesting speak under single-view working mode, and can only support one of said two functions. The invention make conference terminals controls the remote video camera by using the control interface of the remote video camera or the keystroke in the remote controller such that by using the remote video camera control protocol, and on the MCU, such functions can be implemented: chairman selects listener or chairman selects next chairman or listener applies speaking or calling / hang up or switching view-splitting mode or controlling the remote video camera and switching picture between multi views under the multi views working mode.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a video conference autonomous control method based on a remote camera remote control function. Background technique [0002] The Multipoint Control Unit (MCU) is a key device that provides multipoint video conferencing services for many users not limited to one enterprise or institution on a broadband network. Dozens or even hundreds of independent multi-point video conferences can be held simultaneously on one MCU, and the users of these conferences may belong to different industries and different organizations. [0003] figure 1 Shown is a schematic diagram of the structure of the multipoint video conferencing system on the centralized control network of the multipoint control unit. MCU 101 is connected to video conference terminal 103 through IP network 102 . In a video conferencing system, terminals can be divided into categories accordin...
