What do you need to pay attention to when choosing an online set-top box? Xiao Bian today summed up a few network set-top boxes to buy experience to share! In fact, the most important use of the network set-top box is to watch video-type programs, so having a strong network video playback capability is the most important, such as the Taijie box WEBOX these, in the video playback experience to do quite well. In addition, when choosing a network STB, it is best to avoid common problems: crashes, flashbacks, Caton, third-party compatibility issues, and more. Network set-top boxes that can avoid these problems are a good choice.


2. Video Decoding Capability The most important function of the network set-top box during video playback. The video decoding capability is related to the network video playback speed, stability, and supported video formats. Only powerful video decoding capabilities can guarantee a good user experience. Some manufacturers themselves have experience in video software development. Therefore, they have better support for various video formats and video decoding. For example, billions of broadcasts, such as the quality of boxes made by such manufacturers is more assured.

4, system updates and maintenance of friends who have used Android phones may have heard of the firmware, I believe there are many friends update their firmware, Android system development is relatively fast, and is an open source system, prone to loopholes, so the general manufacturers will conduct Firmware upgrades fix some bugs, so it's important that the manufacturer regularly update and maintain the system.
To sum up, the above are some of the Internet set-top boxes to buy skills, of course, what to buy specific needs or need to start from the individual needs. I will recommend the Internet TV set-top boxes for both internal and external use. Interested friends can refer to the following

Why do you like to use ferrite magnets? Because it does not rust, does not oxidize, does not corrode and is absolutely environmentally friendly.
Why don't ferrite magnets rust?
The chemical name of ferrite magnet is iron tetroxide. The main components are: Fe3O4. It is already an oxide of iron, so it is very difficult to be oxidized again. Other magnets (the main component is iron) are made of magnetized metal iron or other elements. Like other iron and steel, they can be oxidized and rusted, and the oxidized part will lose their magnetism.
What are the advantages (advantages) of ferrite magnets
1. Low cost, low price. Raw material cost is cheap.
2. Good temperature stability. It can be used in temperatures of -40 degrees Celsius and +350 degrees Celsius.
3. It is just mentioned that it does not rust.
4. The demagnetization curve is approximately a straight line.
5. Light weight, density is (4.6-5.1) X103kg/M3
6. The anisotropy constant of the magnetic crystal is large.
7. Large coercivity Hc (between AlNiCo alloy material and rare earth cobalt permanent magnet material)
8. High resistivity.
