Problems solved by technology

If there is a problem with any pair, the system will not work normally; if the system is configured with channel backup function, in general, the faulty terminal or MCU will have abnormal images; Can result in terminal dropouts, complete failure of voice and video
[0003] At present, there is a need for a technical solution for automatic speed regulation of the entire network of the broadband dedicated line conference TV system to solve the problems of terminal dropouts, voice and image failures

Embodiment Construction

[0035] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0036] First, in order to better illustrate the patented method, several basic concepts are defined first.

[0037] Channel rate: n*E1 (n=1, 2, 3, 4) transmission rate between the terminal and the MCU or between the MCU and the MCU, the channel rate detected by the terminal is consistent with the channel rate detected by the MCU; Channel cross configuration and rate confirmation are performed through the channel backup module.

[0038] Typical networking such as figure 1 As shown, between MCU and MCU, between MCU and terminal, and between terminal and terminal are generally connected by 4 pairs of wires. The rate of each pair of E1 wires is 2M, and the maximum communication speed can be 8M. At this time, the whole network can only ensure the normal communication through automatic speed up and down.

[0039] Channel backup: multiple pairs ...

Abstract

The invention discloses a method for backing up signal channels of a wideband private line meeting television system and a method for allocating signal channels. The invention comprises the following steps that: the minimum value(S) of the speed and the allocation speed of presently available signal channels is worked out, if the S value is equal to the S' value of the present communication speed, the number(k) of presently used available signal channels are counted, and the k is an integer; if the k is less than the S, whether the main signal channel is cut is detected, if yes, all signal channels are re-allocated. Due to the application of the invention, the consistence of the communication speed and the signal channel allocation between two points is realized, the continuous communication of signaling and voice is ensured, the image can be recovered as soon as possible, and the whole process is fast and accurate, thereby greatly improving the stability of the wideband private line meeting television system.

Description

technical field [0001] The invention relates to a video conference system, and more specifically relates to a channel backup method and a channel allocation method of a broadband dedicated line video conference system. Background technique [0002] In the broadband dedicated line conference TV system, the connection between the MCU (Multipoint Control Unit) and the terminal is shown in figure 1 , including between MCU and MCU, between MCU and terminal, and between terminal and terminal. Two pairs of E1 special line connections are required, generally 1-4 pairs of E1 dedicated lines to carry 2M-8M dedicated line broadband conference video communications. Assuming that there are x terminals and y cascading ports in the system, and the network is built with 8M bandwidth, then there are 4*(x+y) pairs of E1 dedicated lines in the whole system. If there is a problem with any pair, the system will not work normally; if the system is configured with channel backup function, under ...
