Problems solved by technology

[0003] like figure 1 As shown, the existing interactive system includes a plurality of remote terminals, which are used to collect, process, transmit and receive audio and video signals. The received audio and video signal data is often directly transmitted to another remote terminal through the switch. Due to the large amount of data, the transmission delay is too long, so that each terminal cannot be synchronized with the video signals of other terminals, which cannot meet the real-time interaction of various remote systems. requirements

Abstract

The invention relates to a real-time interaction technology for an interaction system, in particular to a multi-party remote interaction system. The system comprises a plurality of remote terminals used for acquiring, processing, transmitting and receiving audio/video signals; each terminal comprises a switch used for being in network connection with each terminal to perform data exchange; and a microprocessor unit is connected in series in front of the switch and is used for compressing the audio/video signals. The microprocessor unit is arranged before the switch of the current each terminal, compresses the audio/video signals acquired by other equipment and transmits the audio/video signals to other remote terminals, the microprocessor unit performs high compression processing on the audio/video signals by adopting a Kalman algorithm, and exchange data quantity among remote terminals is reduced; therefore, real-time interactive efficiency among the plurality of terminals is improved.

Description

technical field [0001] The invention relates to a real-time interactive technology of an interactive system, in particular to a multi-party remote interactive system. Background technique [0002] With the development of science and technology, remote interactive systems have appeared in recent years, which are used in network chat, network education, teleconferencing and other fields. [0003] Such as figure 1 As shown, the existing interactive system includes a plurality of remote terminals, which are used to collect, process, transmit and receive audio and video signals. The received audio and video signal data is often directly transmitted to another remote terminal through the switch. Due to the large amount of data, the transmission delay is too long, so that each terminal cannot be synchronized with the video signals of other terminals, which cannot meet the real-time interaction of various remote systems. requirements. Contents of the invention [0004] The purp...
