What should I do if I watch a black screen, if there is no video and video is not synchronized?

When you watch videos through smart TVs or TV boxes (hereafter collectively referred to as smart TVs), have you ever encountered such problems: TVs have images but can't hear sounds, can hear sounds but there are no images, video and audio are not synchronized, TV The picture of Karton... This time, Xiao Bian explained to you what these problems are caused by, and what methods should be adopted to solve them.



The cause of abnormal video images and sound

The picture or sound of the TV is abnormal, and most of them are caused by problems in the video decoding of the smart TV. We can compare the video file to a puzzle that is disrupted. The smart TV is responsible for restoring the puzzle within a specified time. This reduction process is called decoding. There is a steady stream of fragmented pieces of video that you need to watch online. You need TV to quickly restore. If the TV is not "smart" (system is defective) or the action is "slow" (hardware performance is insufficient), there will be jigsaw errors and incomplete puzzles. The picture and sound are not normal.

So how can we solve this problem? In fact, there are two video decoding methods: hard decoding and soft decoding. When the hard decoding capability is insufficient, we can switch the decoding mode to soft decoding to improve compatibility. You can also replace a video software of the same type from the sofa butler. If you have problems with HDP live broadcast on your TV, it may be normal to use micro live streaming. It may be perfect that his TV is compatible with a small micro live broadcast instead of HDP live streaming. Downloading other applications from the sofa butler is very simple, the following focuses on how to switch to video software decoding.

Switch decoding modes directly when playing videos

Some software switches the decoding mode very conveniently, can press the menu key while playing the video, then switch directly in the pop-up window. Such as HDP live, pudding video and push a single video and the like.


Select change decoding method in playback settings

There are also some video software, you need to find the playback settings in the software settings, select the decoding mode in the playback settings, and then change the decoding method you need. Such as TV cats and VST micro-audio.



Which of the above methods are not used?

If your network is normal, switching decoding methods and changing the video software can not solve the problem of video and audio out of synch, screen stabbing, big fat insects suggest you spend two or three hundred, start (change) a mainstream TV box to solve you The problem is that Huawei and Xiaomi are great TV box brands. Of course, if you face these problems there are other good ways, welcome to share your experience in the comments for everyone!
