Speaking of network set-top boxes, everyone must be familiar with them. But just like when you buy electronic products like mobile phones and TVs, you may not pay attention to their chips. The most important thing is to look at the appearance, functions, and several core CPUs. Some merchants also sneak a sneak peek and do not tell consumers the clear product parameters. Because of this, today we have a brief summary of the chip technology used in the network set-top boxes on the market today (mainly Quan Zhi, Rui Xin Wei, Hai Si, Jing Chen and Actions), the wrong place welcomes you to shoot bricks, but Be merciful!
Comparison of major chip technologies: (absolutely let you rise posture!)
Full ambition
Quanzhi chip, English name Allwinner, is headquartered in Zhuhai. All-in-one uses A10 on single-core products. Although it is not early to do single-core products, it has been widely used in sales and popularity because it has been tested by ARM. Following the single core, Quanzhi has introduced the A20/A20s dual-core, A31/A31s quad-core processor. A10 Because it is a single-core Coretex-A8 architecture chip, the process is 55nm, which is expected to be rare at the end of this year. The Quanzhi A20 is based on the ARM Cortex-A7 and Mali400MP2 GPU architecture and supports 2160p video decoding and H.264 1080P@30fps video encoding.
Among them, Quanzhi A31s is the first quad-core processor based on ARM Cortex-A7 core. With its excellent performance and ultra-low power consumption, it has quickly occupied the mainstream market. Although it is still 40nm process, it can support 4K video software decoding due to its relationship with SGX544MP2 GPU.

2. Ruixinwei
The development of Ruixinwei is earlier than that of Quanzhi. After all, people started from the era of repeater chips. Ruixinwei's headquarters is located in Fujian. Because it tasted the sweetness of the 2918 chip in the single-core era, it quickly followed up with the A9 dual-core RK3066 and the quad-core RK3188. The RK3188 uses a quad-core Cortex-A9 architecture and a 28nm LP process. It is very powerful and can perfectly support 4K video output. The official claims that its computing speed is 30% faster than the Cortex-A7 architecture, and is currently the mainstream chip technology in the network smart set-top box industry.

3. Hai Si
Haisi is the chip department of Huawei. Its research and development of semiconductors can be said to be the most nationalized mark of all chip companies in China. We can directly distinguish them from the naming. The Hisilicon chips that started at Hi are all sold externally, and the beginning of the K word is exclusively for Huawei. Among them, Hi3716 series is the most successful chip in Haisi set-top box, but Hisilicon chip is used in smart phones, video surveillance and TV boxes, and there is no docking tablet product.

4. Crystal morning
Jingchen English name is Amlogic. Many years ago, the digital photo frame specially designed for the gift market was mainly equipped with the crystal morning chip. Also the semiconductor company's Crystal Morning, headquartered in Santa Clara, Calif., has branches in Shanghai, Shenzhen, Beijing and Hong Kong. There are many types of products involved in Jingchen Semiconductor. Many multimedia devices such as tablet computers, digital TVs, set-top boxes, and digital photo frames are produced by the crystal morning Amlogic chip.
Among them, Amlogic8726-M3 is the first mass-produced single-core A9 chip in China. Its frequency defaults to 800MHz (some products will increase its frequency to 1GHz). It is powered by Mali-400 MP GPU and its performance is compared with the current mainstream dual-core quad-core. Naturally poor.
Amlogic8726-MX is a dual-core A9CPU with a default frequency of 1.5GHz. The GPU part is also a dual-core Mali400. It is worth mentioning that its GPU part supports 3D and low bit rate 1080P output, and also supports Flash hard decoding. The performance is smoother.
Amlogic's latest chip is completely different in name from the previous one, due to its Le 8nm process technology, based on the latest Cortex-A9 architecture. Their models are quad-core M801/M802 and dual-core M803/M805.

5. Actions
The time when Actions entered the box was late, but just in time for the explosion of the box, the development of the software had a certain foundation. Therefore, Actions did not take a lot of detours when developing the UI interface system, and all aspects were also more standard. The peripheral interface is also developed in strict accordance with the standard, so that it is faster to connect with the manufacturer.

Steel poles are commonly used to carry several types of electric power lines, distribution lines and lighting system. Distribution lines carry power from local substations to customers. They generally carry voltages from 4.6 to 33kV for distances up to 30 miles, and include transformers to step the voltage down from the primary voltage to the lower secondary voltage used by the customer. A service drop carries this lower voltage to the customer's premises.
