The peripherals of the network video conferencing system mainly include audio equipment and video equipment. Video conference external equipment purchase, audio external equipment mainly includes audio playback equipment and audio capture equipment, audio playback equipment is relatively simple, generally use amplifier or speaker only, and audio capture equipment is more complex, audio capture equipment can Is it a headset, gooseneck microphone, omnidirectional microphone, or even a mixing console? There are so many types of audio capture devices. How do we debug it?

First debug the audio capture device, we only need to do three aspects. The first is to determine that the audio capture device can collect the sound. Now many video conferencing systems have a progress bar with a microphone volume, we can progress through the sound Changes in the bar to observe whether the sound can enter the microphone inside, so as to determine whether the microphone is receiving normal, if the sound reception is not normal, we can see if it is muted, or there is no access to the microphone access hole;

On the other hand, we also need to debug echo cancellation. Echoes can affect the audio effects of video conferences. Therefore, video conferencing systems generally provide echo cancellers, but some video conferencing systems do not provide echo cancellation, such as some software video conferencing systems. The effect of echo cancellation is poor, so we must also have a microphone with an echo suppressor. When we test the echo, we need to open the external speaker on the other side and then talk to see whether our voice will be heard. If we don't hear it, the echo will be suppressed. Otherwise, the echo suppression will be invalid.

Video external devices also include video playback devices and audio capture devices. Video playback devices are mainly monitors, televisions, or projectors. These devices use the VGA interface or the HDMI (high-definition) interface for playback.
