Summary Of Frequently Asked Questions In Video Conferencing

Summary of frequently asked questions in video conferencing

With the gradual application of video conferencing from the professional field to the consumer domain, users are becoming more and more popular. However, due to the strong professionalism, most users are not very familiar with the video communication products, and therefore, for some practical problems are often helpless. Given the convenience of the application, if users can solve some small problems themselves, it will save a lot of manpower and material resources. Here are some simple questions and solutions for reference.

Problem 1: unable to collect local images or unable to view other participants' images.

In the actual application process, it is a common problem for users to be unable to capture local images or to view images of other participants. In the case of not being able to capture local images, the user must first check whether the camera is connected and the video input device is selected correctly. This kind of problem is mostly caused by the carelessness of the installer. Secondly, for the desktop software conference terminal, the user should pay attention to check whether the system is occupied by other programs. Which leads to no use.

For the phenomenon of "unable to view the images of other participants", users can start from the following three aspects: the main control mode, to see whether the images of other participants are video broadcasting; check whether the other side of the network is a firewall, if so, to see if the firewall port is open; check the other side. The uplink bandwidth or the speed of local downlink bandwidth depends on the speed of the network.

Problem 2: video images are not coherent.

In the application process, if the video image is not consistent, it will seriously affect the effect of the meeting, so it should be solved in time. Generally speaking, users should first check whether their bandwidth is satisfied, especially for high-definition video conferencing applications, after all, the current network environment of many users can not meet the demand for high-definition. Secondly, users should check whether the network has delay, packet loss and other phenomena, which is one of the important reasons for video image incoherence. In addition to the impact of the network environment, the problem of the system itself is also an important incentive. For system problems, users can adjust the size of the image (using a smaller resolution), bit stream, frame number to solve.

Problem 3: there is a big murmur or echo when you can't hear the other person's voice and communicate with you.

Users can check from five aspects: check whether the sound bar on the lower left has waveforms; check whether the sound card driver and the main volume of the sound card are muted or set to a minimum. This is mainly for desktop software terminals; check the mixer, efficiency, speakers. Whether it works normally; check whether there is firewall and whether the port of firewall is open. For the murmur or echo phenomenon in voice communication, the user can solve it by selecting the echo cancellation option in the system. In software products, if the camera is equipped with a microphone, users should pay attention to selecting the correct voice input. It is worth noting that users should try to turn off the microphone or cancel the right to speak in the use of the process can effectively reduce noise.
