Nowadays, many consumptions tend to be rational consumption. What we are paying more and more attention is actually its price/performance ratio. The network set-top box is no exception, and the decisive factor is the internal chip. Today, along with Xiaobian, walk into the world of network set-top box chips.
Different chip solutions have different functions, performances, and process levels. It directly affects the strength and weakness of a box. For example, if you like to listen to music, what kind of chip solution box to buy, what kind of chip plan to buy games, like to see local Video should buy a chip solution box, if you choose the wrong chip solution, then the purchased box can not meet your needs, it is a brick.

1, high-quality TV playback
2, rich video drama on demand resources
3, users free to install video software, play games and so on.

1, Quan Zhi A80
All-Chi A80 eight-core processor, 2GB DDR3 memory, 8GB Nand Flash. At the same time, it can be seen that two different power chips AXP806 and AXP809 are integrated on the motherboard, which seems to mean that the two sets of CPUs in the A80 are powered separately. In addition, there are AC100 audio chips. The interface of the motherboard can support Ethernet, USB3.0 OTG, USB2.0 Host, HDMI 1.4, Camera with up to 12 million pixels and many other extended applications.
2, Ruixin micro RK3288
The Rockchip RK3288 chip has an unprecedented performance improvement. At the same frequency, the A17 architecture has a performance improvement of about 50% compared to the A9 and A7. The latest Mali-T76x GPU has more performance than the popular Mali-450. Increased by 200% and available in H.265 encoding format, compatible with 4K quality. Compatible with HDMI1.4 HD interface, can't play 60 fps 4K movies, can only play 30fps 4K should be i video, can't upgrade HD interface to HDMI2. Interface, for high refresh rate 4K movie, RK3288 box can't bear this time Heavy duty.
3. Huawei HiSilicon 3796
Haisi quad core, H.265, 4K, Gigabit network card, USB3.0/SATA interface, DTS/AC3 hard solution, Blu-ray 3DISO, 7.1 generation source code output, Thunder remote control download, intelligent learning remote control, genuine mango TV.
4, Jing Chen S812
Crystal morning Amlogic S812 chip CPU uses Contex-A9, 2GHZ*4 core, Mail-450 6+2 core, DDR3-2G memory, divided into 8G and 16G storage 2 versions, supports 2.4G and 5G wireless, integrated AP function, support 3840*2160 resolution output, the operating system is directly upgraded to Android 4.4.

First, the main chip
Since more than 80% of domestic free film sources are in RM/RMVB format, the existing mature full HD (1080P, FULL HD) chips such as sigma design 8635 do not support RM/RMVB format, in fact, they are all in Europe and America. Designed by people, it is not suitable for China's national conditions. Quasi-HD (720P, 1080i) chips C2 and M-star each support RM/RMVB format, but they have not been tested by large-scale production, the problem is not exposed enough, and the price is too expensive, the whole machine must be 800+, already The price close to the HD machine is actually at the level of enthusiast users, and the market prospects are unknown.
Now mainstream RM players basically use AMLOGIC7228 chip, the resolution is up to 1024*576, the code rate is up to 1600K, slightly higher than DVD quality video (720×480 for NTSC and 720×576 for PAL). The price of the whole machine is below 250 yuan, which is already lower than the psychological threshold of mass consumption, so the market scale is gradually expanding.
Because AMLOGIC chip is widely used in digital photo frame, this makes the 7228 chip mature very fast and stable much better than similar chips, so you must be able to ask what chip it is when you purchase it, because other The chip rate supported by similar chips can only reach 400-1300K.
Industrial Computers and commercial computers have always been inextricably linked. They each have their own application areas, but they affect each other and promote each other, reflecting the progress of science and technology. At present, it is better to do Sanqi Tuoda in China and Advantech in Taiwan. Advantech has a higher reputation, but its price is higher. The industrial computer site can be embedded in the machine, cabinet or placed on the operation table, and it can be used as a man-machine display interface. It is used in telecommunications, electric power, multimedia, national defense, automation equipment, manufacturing and other fields. It is used as a man-machine interface, thin client, PLC and POS communication and control terminals. Digital hospitals are used as bedside service terminals and outpatient terminals to improve hospital service and management. Banks, shopping malls, hotels, railway stations, buses, subway stations, parks and other public places as media (advertisement) players or inquiry terminals. High-end residential quarters are used as home service terminals to implement intercom, message, cost inquiry, product order, home appliance management, temperature and humidity control, etc.
