Video command/session system without MCU and method

Abstract

The invention aims to provide a video command / session system without a micro-programmed control unit (MCU) and a method applied in the fields of production scheduling, emergency command and the like of industries of electric power, petrifaction, army and the like. The system is based on a soft switch architecture and comprises a plurality of Internet contact center (ICC) video command terminals, a device vector table (DVT) desktop video communication terminal, a model view controller (MVC) mobile video acquisition and communication terminal, a forward voice channel (FVC) fixed video acquisition and communication terminal and a video disk recorder (VDR) video server. The session initiation protocol (SIP) adopted among the components of the system is used as a call control protocol. In a video command or video session, the audio is mixed by an intelligent sound mixing module of the ICC, and the mixed audio is transmitted to the related terminals; and the video is pushed to a plurality of DVTs by the ICC to watch, and the DVTs and the low level ICC can also actively apply for calling the video of a certain channel. The video is automatically distributed by a receiving end so as to realize a video command / session without the MCU or a multicast mode.

Description

Technical field [0001] The present invention relates to the technical field of video and voice communication, in particular to an MCU-free distributed video stream processing method in a video command / conference system, and an application for organically combining video conferencing and video surveillance that supports the combination of multiple video Push and single video application The mode also involves a mobile video capture and communication terminal, and an integrated desktop terminal that integrates a conference terminal and a PC display. Background technique [0002] With the development trend of industry users to improve their management level and enhance their awareness of safe production, how to reduce operating costs, improve work efficiency, strengthen the connection between various departments in different places, ensure that the superior has a clear understanding of the lower-level working environment and working conditions, and improve the emergency situation Pr...

AI Technical Summary

Problems solved by technology

The high price of the MCU itself, including the replacement or cascading of MCUs due to expansion, means high investment for users, and also means that the video conferencing system based on the MCU system has poor network scalability and can only be expanded within the range of MCU port configuration.

[0007] From the perspective of user operation, the existing mode is cumbersome to operate. Before the meeting starts, conference operators who are familiar with the system software and hardware are required to set up the system accordingly, including editing conference members and configuring transmission network parameters. The venue personnel cooperate to debug the conference terminal of the sub-venue

Such a specialized use mode makes it impossible for users to use services at any time like familiar telephone dialing.

[0008] To sum up, the inherent defects of the existing model have caused industry users to use the existing system to fail to meet user needs when faced with their individual needs such as production scheduling, emergency rescue command, and remote consultation. Inconvenient to use
