Embodiment Construction
[0031] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0032] Embodiments of the present invention provide a multi-point control unit cascade system, such as figure 2 As shown, it includes multiple MCUs and a business management center (not shown in the figure) that manages the multiple MCUs. The cascading mode between these MCUs is mesh cascading. There is a bidirectional cascading channel between every two MCUs in the system. That is, MCU1, MCU2, MCU3, MCU4, and MCU5 are all connected to each other. Among them, a plurality of conference sites such as T31 to T3m are hung under MCU3 (m is an integer greater than 1), and a conference site T51 is hung under MCU5.
[0033] The business management center in the system is a functional entity that manages MCUs. It can be operated by users to manage on...
