Abstract

The invention discloses a video communication system, a device and a caption display method thereof. The system or the device comprises a voice picking module, an image picking module, and a voice recognition module and a video encoder module which are mutually connected, when video communication is set up, the voice recognition module and the voice picking module are connected and transmit a received speech signal after being converted into a text signal to the video encoder module, the video encoder module is connected with the image picking module, and the text signal and the video signal received by the image picking module are transmitted after being superimposed and encoded by the video encoder module,. By adopting the video communication system, the device and the caption display method thereof, a user can directly decode a displayed image and word information corresponding to voice by encoding and sending the voice signal after being recognized into the text signal and being directly superimposed onto the video signal, therefore, the method is simple, and the real-time is high.

Description

technical field [0001] The invention relates to a video communication system, a device and a subtitle display method thereof, in particular to a video communication system, a device and a display method suitable for a video conference. Background technique [0002] With the development of VoIP, DSP processing, network bandwidth and other technologies, contemporary people have been able to conveniently make calls in different places through video conferencing systems, and see the other party's voice and smile through images. A traditional video conferencing system usually includes a video terminal, a transmission network and a multipoint control unit MCU. The video terminal is used to receive local audio and video input, encode the audio and video stream, and then send it to the remote end through the transmission network. It is also used to receive and decode the audio and video stream from the remote end, and then pass The local speaker and monitor restore the sound and im...
