Description
Technical Field
The utility model relates to a video conference field especially relates to a multiple spot video conferencing system.
Background
The MCU is an important component of a video conference system, and when a video conference is held in more than two meeting places, the MCU must perform tandem, distribution, and switching of signals of the multiple meeting places, and control the conference. The MCU is just like a switch, is a processing point for the connection and exchange of signals such as audio, video, data, signaling and the like of each video conference terminal device, and is cascaded with other MCUs. After the information stream of each video conference terminal is synchronously separated by the MCU, various information such as audio, video, data, signaling and the like are extracted, the same information of each terminal is sent to the corresponding information processing module, and the processing of the corresponding information is completed, for example: mixing or switching of audio, mixing or switching of video information, broadcasting and routing of data information, timing and signaling control, etc. Finally, the processed audio, video, data and signaling are recombined and sent to each corresponding meeting place. The traditional video conference adopts E1 networking and MCU cascading mode, and adopts three-level cascading, namely, a first-level headquarter, a second-level province company and a third-level city company mode. With the continuous enhancement of the degree of entrepreneurization, the work communication among all levels is more frequent, and higher requirements are put forward on a video conference system. The existing video conference system is to be promoted and mainly embodied in the following aspects: firstly, the configuration of a conference terminal cannot meet the requirement of holding multiple conferences simultaneously; secondly, the networking mode is inconvenient, and the utilization rate of equipment resources is low; thirdly, effective communication between systems cannot be realized. Meanwhile, the price of the MCU is expensive, and the price is more expensive as the number of the MCU is more; the MCU is complex to install, a plurality of interfaces are provided, the MCU needs to be installed one by one, and non-technical personnel often plug wrong wires; MCU dilatation is difficult, and every MCU all has fixed point, and the later stage dilatation is very inconvenient.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's not enough, provide a multipoint video conference system.
The purpose of the utility model is realized through the following technical scheme:
a multipoint video conference system comprises an MCU resource pool, conference terminals and an MCU management terminal, wherein the MCU resource pool is respectively connected with the conference terminals and the MCU management terminal; the MCU resource pool controls and transmits the data of the conference terminal, and the MCU resource pool is supervised by the MCU management terminal.
Further, the conference terminal comprises a first-level conference terminal, a second-level conference terminal and a third-level conference terminal; the first-level conference terminal, the second-level conference terminal and the third-level conference terminal respectively comprise a camera, a microphone, a display screen, a loudspeaker and a core codec; the core codec is connected with the camera, the microphone, the display screen and the loudspeaker respectively, and is connected with the MCU resource pool and used for coding images and sounds input by the camera and the microphone and then sending the coded images and sounds to the MCU resource pool through a network, and meanwhile, decoding data transmitted from the network and then restoring the decoded data to the display screen and the loudspeaker.
Further, the MCU resource pool includes a plurality of MCUs, and the shared resources are formed by virtualizing ports of the MCUs.
Furthermore, all MCUs in the MCU resource pool have respective ID addresses, and each MCU is connected through the Ethernet, so that the cloud of the MCU resource pool is realized.
Furthermore, each MCU in the MCU resource pool has three states of available state, unavailable state and failure unavailable state; when the system calculates resources, each MCU is used for calculating the resources indiscriminately; if the MCU is unavailable, the system does not use the MCU computing resource; if the state of the MCU is failure unavailable, the system still uses the MCU to calculate resources.
Furthermore, the MCU management terminal is used for managing the MCU resource pool, and when a conference is held or reserved, the MCU in the MCU resource pool can be manually allocated, and the MCU in use can be switched when the conference is held.
The utility model has the advantages that: the system can meet the requirements of in-line use of the video conference system, ensure the high-efficiency, stable and reliable operation of the video conference system, ensure the quality and effect of each conference, save the existing resources, reduce the expenditure and avoid the waste.
