1, the network environment is decided
The network set-top box transmits signals through the network. Therefore, a reliable and stable network speed is a prerequisite. Current network set-top boxes require at least a total of 2-4 megabits of stable Internet speed to be used smoothly. If they are less than 2 megabytes, it is difficult to obtain a smooth viewing experience.
In China, the stability of the network provided by different network service providers is also different. Among them, the stability of the telecommunication network is the best, followed by Unicom, Railcom, and Mobile, followed by Great Wall Broadband. If the family has only 2 megabits of network speed, you can choose to use the Action Plan set-top box; if you have more than 4 megabytes of bandwidth (non-Great Wall,) you can choose the Android system products, such a box is too much, no longer say.
2, functional requirements
If you only watch TV live broadcasts and video on demand functions, you may choose to use Dyomaete, Yidian, or Yigerui to meet the demand and have a cheap price. If you also want to experience a large game, high-definition local playback, etc., 300-400 yuan box is enough.
3, chip solution
Currently on the market mainstream Android chips for Quan Zhi, Hass, Rockchip, Crystal morning four. The chip plan includes the A31, A31S of the whole ambition; RK3166, RK3188 and RK3288 that will come to the forefront of Ruixin Micro; K3V2 of Hass; S805 of Jing Chen. Among them, QuanZhi's chips are known for their GPU capabilities and low cost. Rockchip's microchips are respected for their powerful CPU performance and relatively low cost. Hass chips have excellent decoding capabilities, but their cost is high. The chip Chen's comprehensive quality is high. There is no weakness, so the cost is the highest.
4, CPU
Like a computer, the CPU is an important standard for checking the performance of a box. System response speed, video decoding speed, program running speed, and other basic functions are all linked with CPU performance. Most of the boxes on the market today are equipped with quad-core chips.
5, wireless receiving capacity
It is common for several mobile phones and several computers to have wireless signals in the home. It is easy for so many signals to interfere with each other. Not only does the box run unstable, but it also delays the speed of the box. Therefore, many families only need to retreat to the box to access the Internet to ensure signal stability. Is there any way to stabilize the signal without the use of network cables? The answer is yes, as long as the box itself has good shielding performance and the Wi-Fi antenna signal is strong. There will be no problem.
6, video support
After the agreement is supported, the next step is to talk about format support. After all, anyone who does not want to work hard will not be able to put it out. In addition to the more common MP4, WMA, and AVI formats, FLV, RM, VOB, 3GP, RMVB, etc., are also the best ones to support. Everyone can see the video formats it supports on the box's packaging, and compare whoever supports it.
7, heat dissipation
The box as a household product is an important piece of electrical equipment. The opening may be a day without moving the nest, and the battery life is particularly important. When you select the machine, it has a lot of cooling holes. When the body is operating for a long time, it won't burn hot. The body is metal and not very hot. It's a very good design. Most of the current box product casings are plastic, PC materials, and some are pure aluminum metal, superior heat dissipation. Finally, look at the power. The higher the power, the more power it consumes and the easier it is to generate heat.
