Smart TV (parameter picture article) has become more like a mobile phone. The standard of purchase is no longer just to look at the screen size. More hardware performance and functions need to be considered. Otherwise, there is only one display like traditional TV. However, TV and computers and smart phones are very different in their use. The demand for hardware is also different - especially in the current 4K era. According to the characteristics of 4K smart TV, we will analyze how to correctly select the TV through the hardware parameters of the chip. First, CPU CPU As the functions of smart TV systems become more and more complex, applications become more and more abundant, and the requirements for chip computing performance are getting higher and higher. The performance of the chip depends on the number of CPU cores and the running frequency, which will affect the smoothness of the UI system and various applications and games. Today, smartphones are generally quad-core and eight-core, and TVs certainly cannot fall behind. The strongest chip in smart TV in 2015 was the MSD6A928 from MStar Morningstar, which uses a quad-core ARM Cortex-A17 design to run all existing applications smoothly. With superior 4K decoding capabilities. Considering that Cortex-A17 and Cortex-A53 have become mainstream, TVs using Cortex-A7 and Cortex-A9 are somewhat worrying. Although the UI fluency can be ensured by simplifying system functions, future smart applications may be Can't run smoothly. And because the screen resolution of 4K TV is 4 times that of 1080p, the performance requirements are also higher. A17 and A53 chips should be the first choice when purchasing. Second, GPU graphics processor The GPU is similar to the graphics card on a computer, except that the TV does not have a separate graphics card. The GPU and CPU are integrated on one chip. Many friends will have this experience: using a computer with a high configuration, running software or browsing the web is very fast, but it is very good when playing a game - the reason is that the performance of the graphics card is too bad, causing a bottleneck. The same is true for smart TVs. The GPU is primarily responsible for graphics rendering. This is especially important for games, and requires a strong GPU and CPU to provide a smooth gaming experience. At present, there are several GPU models in smart TVs, such as PowerVR SGX series and ARM Mali series. The aforementioned Mstar 6A928 chip integrates the MaliT760MP4 quad-core GPU, which basically meets the requirements of the Android platform. In addition to regular games, a powerful GPU can provide more gameplay. For example, LeTV X50 Air provides a 3D game function. With special settings, games that support OpenGL technology can be converted into 3D games. Currently, more than 300 games support this technology. Wearing 3D glasses, you can not only enjoy 3D movies on the X50 Air, but also play interesting 3D games - of course, if you have a powerful GPU, because the GPU rendering graphics workload will double in 3D mode. If the performance is not enough, it is easy to appear. Third, 4K decoding ability The core number and frequency mentioned above actually refer to the CPU part, which is equally important for smartphones and smart TVs. But the TV is used to watch video, so more need to consider the video decoding ability, especially the decoding ability of 4K video, this part is the difference between TV and mobile phone. The mainstream TV chip will integrate the decoding circuit and the CPU on the same chip to save cost and power consumption. A few years ago, when 4K TV was born, some models appeared. Although it provided a 4K LCD screen, it did not support the decoding of 4K video. It was called “fake 4Kâ€. We can’t make such a low level now when we buy 4K TV. error. But now also pay attention to whether the chip support for the 4K format is comprehensive. At present, 4K videos are mainly in H.264 and H.265 formats. The former has been available for more than ten years and is commonly used in 1080p full HD video. The latter is a new standard and is designed for 4K and 8K Ultra HD video. of. According to the data, the video file generated by H.265 encoding of the same quality video is half the size of H.264. This means that H.265 encoded 4K video not only takes up much less hard disk storage space than H.264, but also consumes very little bandwidth for online viewing of H.265 encoded 4K video. The aforementioned 4K TV dedicated chip: Mstar 6A928 supports 4K decoding in both H.264 and H.265 formats. TVs that only support H.264 will obviously be in awkward position after the emergence of a large number of 4K content in the future. It is also inconvenient after buying a home. If you want to watch H.265 format 4K video, you have to connect to a TV box or a computer. Fourth, RAM running memory Running the memory is relatively simple, mainly to see the size of the capacity, many old smart TV menus are very slow, often crash, one of the main reasons is that the memory is too small. Nowadays, Android 5.0 and above systems have higher and higher requirements for content. The 1GB memory mobile phone response is very slow, not to mention smart TV, so 2GB is the most basic requirement. However, some manufacturers use the flicker technique when propagating, for example, a TV memory is only 512MB, but it is 4Gb when propagating. This is playing a word game, because 1B = 8b (B is the abbreviation of Bite, b is the abbreviation of bit), we must pay attention to when buying.
