1. Crystal morning Amlogic series
Amlogic is a US-based chip design company. Its AML8726M single-core A9 processor was once popular in the domestic flat panel market. Due to the slowness of upgrading and other reasons, it was gradually overtaken by other solutions. . However, AML immediately turned to the box and smart TV market, but it has laid a world. In terms of box products alone, the famous boxes such as Xiaomi, Baidu, Tmall, Skyworth, and LeTV all use its chip solutions. 
The latest S905 is an improvement over the S802. The hardware performance cannot be improved because the A53 can only be regarded as a 64-bit version of the low-power A7 architecture. The orthodox high-performance A9 architecture is not dominant, let alone the GPU. There was also some shrinking, and the running points were not as high as the former. However, the S905 has improved the specifications of video codec and output support, not only supports H.265 decoding, but also has a larger bandwidth than HDMI 1.4, which enables 4K output at 60Hz, which is at the current leading level. The representative products currently using the S905 include the third generation of the millet box and the latest Lynx box. This program currently does not see products with large memory. Basically, it is equipped with 1GB of memory, which is a kind of regret.
2. Rockchip Micro Rockchips Series
Mentioned that Rising Star would have to mention his flagship chip RK3288, RK3288 itself is also the first processor designed for flat panel, based on quad-core A17 high-performance architecture, with 1.8GHz frequency, often with 2GB of memory, support 4K decoding and 4K Output, the interface itself is 1080P resolution, the program product runs around 3W6. This program itself is also based on high performance, there are also individual models with 4GB of large memory. 
3. Quan Zhi Allwinner Series
The original processor of Quan Zhi Technology was mainly designed for tablet PCs, but as the tablet market entered a downturn, its solutions began to look for other applications such as vehicle-mounted electronic devices (recorders), learning machines, and monitoring devices. Like the older A31s/A20, they all used tablet chips, but the follow-ups were all moved to box products. The Quanzhi program is still very popular in box products. One of the important reasons is video decoding. The early plans of Quan Zhi began to support 4K hard decoding and 3D video synthesis, which was far ahead of the competition. This coincided with the functional requirements of the TV box as the core of video applications. 
From the product road map of Quanzhi, we can see that it will continue to exert efforts on the box market. The H64 of the quad-core A53 architecture and the H5 of the 8-core A53 architecture are planned and will gradually replace the existing H8 and H3 solutions. . In general, one of the major advantages of the Quanzhi programme is that it is cheap and excellent decoding, but generally it is a pity that the ISO Blu-ray disc is not supported, and the interface itself has a low resolution.
4. Actions Actions
Established in 2001, Actions IC design company has been sticking to the domestic portable multimedia SOC market, but its product application has not been widely used since the MP4 era. In the flat-panel market, the action of the Actions's chips is also ATM7029 processor, but its performance is low, has been criticized, can only be used in part of the white brand products or the main long-term aircraft models above. Although the subsequent ATM7039 used the mainstream quad-core A9 architecture, it was too late to be available and did not have an advantage over its competitors. 
As for the earlier ATM7029 program, not much used on the box, its product fluency is very general, decoding and output have no advantage, almost can ignore this program, there is no new product to use it. Overall, the Actions program continues the trend of declining in the tablet field, and the outlook in the box area is also not optimistic.
5. Hassigili Series
HiSilicon Semiconductor Co., Ltd. was established in October 2004. The predecessor was Huawei Integrated Circuit Design Center established in 1991. At present, the vast majority of Huawei's mobile phones are Hass processors. The products using Hass processor have been sold at home and abroad, and have obviously more international influence than the above-mentioned domestic manufacturers.
After the rise of the network set-top box, Huawei's own "secret box" uses the mobile phone to control the K3V2, and the subsequent Huawei glory box uses the HiSilicon Hi3798 processor. Previously this site also tested a box equipped with Hass Hi3798C processor, the program is based on quad-core A9 architecture, 1.5GHz frequency, often with 2GB of memory, the interface is 1080p specifications, support for 4K decoding and 4K output, program product running About 2W2. 
Hass program products In addition to 4K video, USB3.0 and Gigabit network card these enhanced design, Hass's ExpressX image processing engine is also a great weapon, relying on a powerful internal information base, when dealing with image information can be tones, saturation Degrees, brightness, contrast and other details are optimized. In terms of sound, Dolby and DTS are not only authorized, but also through the optical or coaxial output 7.1 channel surround sound signals, audio and video are superb, it is worth recommending.
6. MediaTek MediaTek Series
MediaTek is not only playing a role in the low-end mobile phone market, but also continuously infiltrating into other areas. The box market will be able to see its presence. Currently, the mini box of millet box sales and Youku K1S are using the MTK MT8685 processor. 
This is a low price as a selling point of the program, based on the quad-core A7 architecture, the main frequency is only 1.3GHz, only supports 1080P decoding and 1080P output. Currently, the prices of related products are very cheap, and they tend to be very small in size. Overall, MediaTek has not invested much effort in the box field, and related products do not focus on high performance.
7. Morningstar MStar Series
Morningstar's MStar solution is not widely used in the TV box field, but its related products have to be mentioned in the box development process, mainly focusing on its MS9180 solution. Last year, the author used a series of products (from Kaibor) successively. People are impressed. 
From the performance point of view, MS9180 1.5GHz quad-core A9 processor, quad-core Mail 450 graphics core is not particularly good. But it has its own strengths. It supports true 4K point-to-point output for the first time. It can also directly play Blu-ray original files, supports HDMI input and output, supports Dolby/DTS decoding, USB 3.0 and Gigabit network cards, etc. This chip has a lot of gameplay. The related products even directly provide a hard disk drive and can directly read the data in the hard disk. At present, TV boxes using the Morningstar MStar program are mostly old and have fewer models.
to sum up:
The above solution providers currently use more network set-top boxes. Overall, several of them have relatively strong performance. Rockchip RK3288 (3368), Quanzhi A80, Morningstar MS9180, Hass Hi3798 solution are more worth recommending, of course, strong performance does not mean that the relevant products are easy to find, in fact, many new low-cost programs are often used more widely . When choosing a box, you can make decisions based on your own needs and budget. If your home TV is still at full HD resolution, then in fact many low-cost solutions can fully meet the demand. If you already use a 4K TV and pursue ultra-high-definition effects, Morningstar MS9180, Rockchip RK3368/RK3288 will obviously be more suitable. For consumers who are particularly critical of their image quality, they can choose products related to the Hass program.
Do you worry about buying a TV box? 7 large chip brand performance comprehensive analysis
With the popularity of smart TVs and home entertainment audio and video equipment, people have more and deeper understanding of the purchase of home appliances, from the choice of the previous home appliance brand, to the after-sales service during the mid-term use, and to the zero of the home appliances in the later period. Parts replacement is at your fingertips. Xiao Bian talks about the TV box chip solution for everyone today. The chip determines the video resolution capability and input quality. At present, the mainstream TV box chip manufacturers have the following 7: At present, AML is relatively mainstream and is a S802 solution. Its representative products include Baidu Shadow Stick 3S, Skyworth Q+ and Xiaomi II Box. The performance of this solution based on quad-core A9 architecture and eight-core Mali-450 GPU is good. , Ann Bunny can reach 3W+. Used on the box rather respected, 4K decoding support complies with the needs of television products, has always been with the well-known domestic box manufacturers have a good relationship of cooperation also follow this program. Its disadvantage is that it doesn't support H.265 decoding. Although it doesn't have much impact, it can't keep up with today's era. RK3368 is the latest platform of Rockchip, which is its first 64-bit CPU, and the first eight-core design, suitable for flat-panel and TV box products. Now that the corresponding tablet has not yet seen, but the box product has been preempted It was used in one step, and domestic high-end TV boxes such as the Taitek box WEBOX WE30 were using this chip solution. RK3368 is based on the eight-core A53 architecture, 1.5GHz frequency, often with 2GB/1GB of memory, supports 4K video, H.265 hard decoding and Blu-ray original file, can achieve HDMI2.0 60Hz output, the system platform for the latest Android 5.1 , The program product runs around 3W2. Since the overall balance is relatively balanced and there are no obvious shortcomings, this scheme is currently very popular in the market and there are a large number of related products. Quan Zhi’s current proposal for the box market is dominated by an eight-core H8 and a quad-core H3. The A80 is a high-performance processor originally developed by Quan Zhi for the tablet market. However, it was not used properly and it is now used on the box. The A80 processor is based on the quad-core A15+ quad-core A7 architecture. The GPU configuration is excellent, and security Bunny can break through the 5W mark. It supports 4K decoding and 4K output, the interface itself is 1080P specifications. Related products are equipped with more than 2GB of memory, individual models will even use 4GB of memory, appear in some of the main high-performance box products, but the brand is generally not very famous.
