Embodiment Construction

[0040] The core idea of ​​the time slot processing device and the method for implementing dynamic cascading of lines provided by the present invention is to provide multiple pairs of cascading ports by multiplexing time slots on the lines.

[0041] Fig. 2 is a schematic diagram of the working principle of the time slot processing device of the present invention. MCU1 22 and MCU2 24 are connected through E1 line, time slot processing device 10 is connected with MCU1 22 and MCU2 24, selects the free time slot from the E1 line, separates the free time slot, and combines the free time slot into a data channel , so that MCU1 22 and MCU2 24 communicate through the data channel formed by free time slots.

[0042] Fig. 3 is a structural diagram of the time slot processing device of the present invention. The time slot processing device 10 includes a time slot selection device 12, a time slot separation device 14, a time slot combination device 16 and a data transmission device 18, an...

Abstract

The invention provides a system and method for realizing line dynamic catenation, the system at least includes the first multi-point control unit, the second multi-point control unit and the time slot process device, the time slot process device is used to select idle time slot, separate idle time slot, and combines the idle time slot into data channel, and transmits data through data channel. The line uses the time slot multiplexing mode, it provides the multi-point control unit to several pairs of catenation ports, and the method includes: selects the idle time slot in the time slot of line; separates the idle time slot; allocates the separated time slot to catenation port; uses the catenation port to transmit data.

Description

technical field [0001] The invention relates to the field of multimedia conferencing television, in particular to a system and method for realizing dynamic cascading of lines. Background technique [0002] In the practical application of video conferencing, for the vast majority of users who use E1 (a line with a transmission rate of 2M) line cascading between two MCUs (Multi-point Control Units), when it is necessary to hold a cross- During the cascading conference of two MCUs, one E1 line cascading port of each MCU will be occupied regardless of the rate of the cascading conference being held. However, in the prior art, the 32 time slots of the E1 line can only be used uniformly, and the other time slots cannot be used if one is occupied, thus causing a waste of line resources. [0003] A specific example is shown in Figure 1a. When a 128K cascade conference is held between MCU1 and MCU2, the entire 2M bandwidth of E1 needs to be occupied. The bandwidth usage is shown in...
