摘要： The embodiments of the present invention disclose a method, a device, and a system for controlling multichannel cascade between two media control servers. The method comprises: receiving a service request message; choosing a target channel among all the channels multichannel-cascaded with an opposite cascaded media control server according to the service request message and a preset channel usage rule; and sending information about the determined target channel to the opposite cascaded media control server so as to enable the opposite cascaded media control server to carry out code stream switching according to the information about the target channel. The method disclosed in the embodiments of the present invention saves cascaded channels and improves the utilization of cascaded channels, thereby saving channel resources.
摘要翻译：本发明的实施例公开了一种用于控制两个媒体控制服务器之间的多声道级联的方法，装置和系统。该方法包括：接收服务请求消息; 根据服务请求消息和预设的信道使用规则，在与相对级联媒体控制服务器级联的所有信道中选择目标信道; 以及将关于所确定的目标信道的信息发送到相对的级联媒体控制服务器，以使相对级联的媒体控制服务器能够根据关于目标信道的信息执行码流切换。本发明实施例中公开的方法节省了级联信道，提高了级联信道的利用率，从而节省了信道资源。

摘要： A Multipoint Control Unit (MCU) cascaded system is provided, which includes a plurality of MCUs under the management of a service management center. The cascade manner between the MCUs in the system is a reticulated cascade. A communications method for an MCU cascaded system, an MCU, and a service management center are also provided. In the embodiments of the present invention, because the connection and networking mode of MCUs in a cascaded system is changed, a transmission path passing the least MCUs can be selected according to a connection situation between the MCUs. Therefore, transmission delay and decrease of video and audio quality due to multiple forwarding by MCUs can be effectively avoided, and thus the media stream transmission time is reduced, and the play quality of the media stream is guaranteed in an overall manner.
