It is sent to controlling terminal.After controlling terminal receives the audio data in the local meeting-place that recording terminal is sent, it is sent to remote site
It plays.After controlling terminal receives the video data in local meeting-place, output is sent to local decoding terminal all the way, by decoding terminal solution
It is shown after code in local meeting-place；Output is sent to remote site all the way, shows in remote site.
More than, the acquisition of the video data and acquisition of audio data is synchronous carries out, controlling terminal is continuous by local meeting-place
Video data and continuous audio data, which are transmitted into remote site, plays display.
Specifically, above-mentioned controlling terminal receives local meeting-place video data, the reception recording terminal hair that camera shooting terminal is sent
The audio data sent, and the video data in local meeting-place and audio data are transmitted to remote site.Above-mentioned controlling terminal
Receive the video data of remote site and the audio data of remote site, and by the video data of remote site and remote site
Audio data is sent to decoding terminal；Above-mentioned decoding terminal receives the video data of remote site and the audio number of remote site
According in the output of local meeting-place after decoding.Above-mentioned decoding terminal receives the video data in the local meeting-place forwarded by controlling terminal, solution
It is exported after code in local meeting-place.
The video data of conference system of the invention, local meeting-place acquisition was both shown in local meeting-place, also in remote site
Display；The audio data of local meeting-place acquisition is only played in remote site, but remote site is sent to the sound that local meeting-place plays
Frequency according to the audio signal that can interfere local meeting-place recording terminal acquisition sound quality, in order to solve this technical problem, this implementation
In example technical solution, the remote site audio data received is sent to camera shooting terminal by above-mentioned controlling terminal, by camera shooting terminal
It is forwarded to intelligent console；Above-mentioned intelligent console receives the local meeting-place audio data that recording terminal one is sent, while receiving by taking the photograph
As the remote site audio data that terminal forwards, above-mentioned intelligent console is to the local meeting-place audio data and remote site received
Audio data, filter out the remote site being mixed in local meeting-place audio data and be sent to the audio data that local meeting-place plays
Noise and echo, export completely without noise, the audio data having no reply to auditory localization.On the other hand, controlling terminal pair
It transmits to the audio data of remote site and also carries out same impurity elimination processing, filter out and be mixed in local meeting-place audio data
Remote site be sent to noise and the echo of the audio data that local meeting-place plays, output completely without noise, having no reply is used for
It is sent to the audio data of remote site, can be further improved the picture effect and acoustical quality of conference system with this.
In addition, being started by controlling terminal in the present embodiment technical solution or waking up camera shooting terminal, and camera shooting terminal should control
The request of terminal and the video data for acquiring local meeting-place；Controlling terminal starts by camera shooting terminal, closes or wakes up intelligence
Holder.
