Problems solved by technology

Although this dual-stream control system has a certain degree of flexibility, it is easy to cause disorder in the venue, especially when the user is not familiar with the system and frequently presses the remote control, it will directly lead to frequent execution of token application actions, making The system scheduling is chaotic, the execution efficiency is low, and it affects the auxiliary stream operation in the normal dual-stream operation
[0005] In some occasions, for example, the speakers of the conference have been arranged in order, and the speakers will speak in this order. If the above scheme is applied, the speaker needs to apply for a token, which increases the burden on the speaker and cannot be used as a speech. Human users provide a good experience

Embodiment Construction

[0049] In the present invention, in order to control the secondary stream operation, the terminal and the multipoint control unit (MCU) are numbered first, and then they are transmitted as part of the control information in the BAS (Bit Rate Allocation Signal) code. terminal number The value range is decimal . is the number of the local MCU (the MCU connected to the terminal), It is the number of the terminal, and the numbers of the MCU and the terminal are represented by 8-bit binary numbers. After the terminal joins the conference, it is initialized according to H.242, and then the local MCU assigns a number to it.

[0050] In the case of only one MCU in the video conferencing system, after numbering, follow the figure 1 The auxiliary stream operation process shown is for auxiliary stream transmission, including:

[0051] Step 101, the local MCU performs initialization, and sends an initialization message flowControlRelease Initialize(channelID, bitRate, terminalL...

Abstract

The invention relates to a method for forcibly controlling the auxiliary stream of a videotext net and a system thereof. The method comprises the following steps: step 1. a local MCU designates an executive termination according to the mark of the executive termination; step 2. the local MCU starts and activates the channel of the auxiliary stream; the local MCU and the executive termination carryout the auxiliary stream operation. The method of the invention can realize the stability of the auxiliary stream operation of the videotext net and improve the experience of attending a meeting fora spokesman.

Description

technical field [0001] The invention relates to the field of video network, in particular to a method and system for forcibly controlling auxiliary stream of video network. Background technique [0002] Video conferencing mainly realizes remote face-to-face communication in the form of voice and video, but with the increasingly widespread application of video system, people are no longer satisfied with just seeing remote video images, and hope to transmit more information, such as meeting Information such as charts, data, or documents used in time, and most of these information exist in the computer as data files. Therefore, in many occasions, video conferencing needs to establish collaborative work with data, such as remote conferences, distance education, remote office, etc., to enhance the sense of presence in the meeting and improve the efficiency of video conferencing. [0003] Initially, people realized the transmission of these information through T.120 data conferen...
