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...

Abstract

The invention discloses a multipoint control unit (MCU) cascade system which comprises a plurality of MCU under the management of a service management center. The cascade manner among each MCU in the system is reticulate cascade. The invention discloses a communication method for the multipoint control unit (MCU) cascade system, the multipoint control unit (MCU) and a service management center simultaneously. In the embodiment of the invention, as a connection networking manner among each MCU in the cascade system is changed, minimum transmission paths though the MCU can be selected according to the connection situation of the MCU, thus being capable of effectively avoiding transmission delay and the reduction of video and audio quality caused by multiple transmitting of the MCU, reducing transmitting time of media streams on the whole and ensuring the broadcasting quality of the media streams.

Description

technical field [0001] The invention relates to the communication field, in particular to a multipoint control unit cascade system and a communication method thereof, a multipoint control unit and a service management center. Background technique [0002] With the continuous development of modern network technology and broadband construction, video conferencing systems have been widely used in work and life. In video conferencing applications, multi-point control unit (multi control unit) MCUs can be cascaded with each other. By holding a cascaded conference, terminal sites under different MCUs can be scheduled in the same conference, that is, there are such figure 1 Cascade networking. MCU2 and MCU4 are hung under MCU1, and MCU3 and MCU5 are hung under MCU2 and MCU4 respectively. T31 to T3m are sites mounted under MCU3, and T51 to T5n are sites mounted under MCU5 (m and n are both integers greater than 1). while using as figure 1 When the video system shown in the video...
