[0005] The present invention proposes a cost-effective audio-visual linkage microphone main unit in view of the fact that the automatic switching device between the panoramic position of the venue and the close-up position of the speaker in the video conference is very expensive in the prior art. By detecting the audio-visual linkage microphone main unit Connect the switch state of the microphone to emit infrared signals to control the video conferencing host to switch between the panoramic position and the close-up position of the speaker

Embodiment 1
[0031] like figure 1 As shown, the present invention provides an audio-visual linkage microphone host 11, comprising: 2 audio input terminals, 1 audio output terminal and 1 infrared control output terminal; the audio input terminal is connected with a microphone 12, and the audio output terminal The end is used to connect the audio system 13, and the infrared control output end is connected with an infrared emitting device 14, and the infrared emitting device 14 is connected to the infrared receiving unit infrared wirelessly of the video conferencing host 15; when the audio-visual linkage microphone host 11 detects a certain audio input When the switch of the connected microphone 12 is turned on, the infrared emitting device 14 transmits an infrared signal to the video conferencing host 15, and the video conferencing host 15 receives the infrared signal and switches to the close-up bit picture corresponding to the microphone 12 to play. When the audio-visual linkage microphone...

A video and audio linkage microphone host provided by the present invention comprises two audio input ends, an audio output end and an infrared control output end, the audio input ends are connected with microphones, and the audio output end is used to connect a sound console or a sound device. The infrared control output end is connected with an infrared emission device, and the infrared emission device is in infrared wireless connection with an infrared reception unit of a video conference host. When the video and audio linkage microphone host detects that a switch of the microphone connected with one audio input end is turned on, the infrared emission device emits an infrared signal to the video conference host, and the video conference host receives the infrared signal to switch to a feature position picture corresponding to the microphone to play. The video and audio linkage microphone host is cheap in price, and can control the video conference host to automatically switch between a meeting place panoramic position and a spokesman feature position by matching the infrared emission device.
Description
technical field [0001] The invention relates to the technical field of video conferencing, in particular to an audio-video linkage microphone host. Background technique [0002] As an efficient remote communication tool, video conferencing can bring together various participants in different places through the network to realize multi-modal communication such as audio and video communication, data interaction, remote sharing and assistance. As a result, videoconferencing is gaining popularity in government agencies. At present, domestic government agencies have basically built a complete multi-level video conferencing network from the national and ministerial level to the township level, and 60% of the meetings between agencies at all levels are resolved by remote video conferences. [0003] Since it is a video conference, discussions and interactions are involved in the meeting. While conveying the spirit of the meeting to the lower levels, the higher-level authorities a...
