PConline talk in the field of smart phones, the processor has always been a major chip manufacturers compete. For Smart TVs, which is also a system running Android, does the main mobile phone chip maker still have such a strong position? In fact, on the contrary, in the smart TV market, it is true that the traditional TV chip is in the world, and some of them are brands that you rarely hear. Some people say that TV can do a good job on the screen, but it is now the era of smart TV.
Having contacted many mobile phones and smart TV conferences, we will find an interesting phenomenon carefully. On smart phones, major mobile phone manufacturers will undoubtedly promote the use of a certain brand of X-core high-performance processors because For many people, whether or not a well-known brand processor is used will be an important factor in whether or not to pay for it; on smart TVs, you will only see words like this: "64-bit quad-core Cortex-A53 processor ". As for the brand of the processor, it is almost never mentioned, which also makes many consumers do not know the specific conditions of the TV chip.
The application of mobile phone chips to television is not ideal
Commonly found on mobile phones are cell phone chips produced by Qualcomm, MediaTek, Samsung, and Hass. TVs generally use powerful TV decoding chips such as Morning Star, Jing Chen, and Rockchip. Nowadays, the vast majority of smart TVs use these unknown chips. Since they are also Android's smart systems, isn't it better to use powerful mobile phone processors on TVs? Some people think so, such as LeTV. After all, from the perspective of performance, traditional TV chips still lag behind mobile phone chips in performance.
Smart TV with 2015 flagship mobile phone processor
On December 22, 2015, LeTV officially released the fourth-generation super TV. What is most noticeable is that the chip it took is officially back in 2015 and the mobile phone chip is ready to return to the topic. It is regarded as pursuing the ultimate performance of smart TV. The top-end processor of the mobile phone plugs into the TV, and enhances the overall configuration of the TV. However, smart TVs focus on video playback capabilities, followed by performance. Compared with the choice of traditional TV chips and Qualcomm, traditional TV chips are unquestionable in video decoding capabilities. Although the performance is weaker than the average mobile phone processor, it is enough to meet the daily needs. The most important thing is that in this era of cost-cutting, the more The higher the cost of a well-known mobile phone processor, it is not a good choice.
Summary: In addition, due to different positioning, mobile phone chips used in television have two main problems: one is TV does not require baseband, in addition to WIFI, Bluetooth does not require other communication functions; second is 4K resolution support, as we all know, mobile phone Mainly as a communication tool, the video decoding capability is not so high. Until the second half of 2015, Sony introduced the world's first 4K screen mobile phone.
TV chip performance is not the only
Speaking of applications on smart TVs, here we give everyone a science app. Video decoding is divided into hard decoding and soft decoding. Soft decoding is just like on a computer. Purely using CPU's computing performance to handle video decoding work, the stronger the CPU performance is, the better the effect of video playback is. Hard decoding uses specialized hardware for video decoding. For example, a GPU for a graphics card can be used on a computer. In a mobile phone, a dedicated decoding circuit is generally added to the main chip. Soft decoding has advantages in compatibility and image effects, but high power consumption problems have not been solved, hard decoding power consumption is minimal, and the cost is extremely low (as opposed to the equivalent decoding capability of the CPU).
Mobile phones and smart TV chips are ARM structures
Mobile phones and TV chips are ARM-based chips, and the three methods of encapsulating CPUs, GPUs, and decoding circuits are commonly used. Because the CPU performance of the ARM architecture cannot be compared with the CPU of the desktop, even the fastest quad-core and eight-core ARM CPUs have very limited performance and cannot play high-definition high-definition video smoothly. At this time, the dedicated decoding circuit helps a lot.
Some mobile processor processors, integrated Adreno series GPU, it must be extra plug-in 4K solution DSP chip, will make the 4K playback is normal, external DSP chip is also solved after the solution does not support 4K playback The complexity of the circuit scheme and the inconvenience of increased costs are not necessary for the television experience.
MStar TV chip supports full 4K format hard decoding
While MStar, Crystal Morning and other TV chips are not as good as Qualcomm's processors in terms of performance, they are still more than enough to cope with daily usage needs. But most importantly, these chips incorporate a dedicated circuit that supports H.2654K hard decoding. No H.265 hard decoding to talk about 4K are naked rogue, this chip not only meets the needs of the CPU performance, hardware decoding has obvious advantages, the most important is the cost-effective enough, which also makes it impossible for Qualcomm to find.
Summary: The advantages of mobile chip solutions lie in the integration of baseband rather than decoding technology, which is the key for mobile phones, but not for smart TVs. Now that 4K TV has become mainstream, it cannot support full 4K format hard decoding, even if it is not a true 4K TV.
TV, mobile phone chip will eventually become one
As mentioned before, this smart TV cake, to say which chip makers are not jealous, is definitely false. In terms of performance, mainstream mobile phone chips have obvious advantages, but they have been dragged down by video decoding and the lack of cost-effectiveness. When 4K mobile phones appear, more and more manufacturers will gradually keep up, and major mobile phone chip makers will further strengthen their support for 4K decoding. By that time, entering the TV chip market will be in vain.
Traditional television chip makers are still enjoying a good time, but smart TVs have gradually highlighted the trend of stacking hardware performance. These traditional brand TV chips have already fallen behind in size in performance compared to mobile phone chips, when the performance of TV chips Already unable to exert enough hardware level, TV manufacturers will start looking for new partners. Looking at the other side, some mobile phone chips can decode mobile phone chips in H.264 (AVC) and H.265 (HEVC) format video, which means that mobile TV chips are gradually becoming more integrated.
The strongest performance TV chip is still inferior to the mainstream mobile phone chip in performance
Perhaps we have gradually discovered that even if the mainstream TV chips such as Morningstar (MStar) have inherent advantages in video decoding, the decline in performance has gradually become apparent. Without a processor with sufficient performance and stability, there are no solutions to the fundamental problems that can be solved, such as the stuck smart TV and the crash. The mainstream mobile phone chips have inherent advantages in processor performance. In the near future, there will certainly be a product that is perfectly compatible with both mobile phones and smart TVs.
Summary: Although the price/performance ratio is still important, the price war can only be played for a while. Consumers pay more attention to the experience. The pace of replacement of smart TVs is already accelerating. Like computers and mobile phones, hardware stacking and performance competition will be the only way to go. Under this premise, if mobile phone chip manufacturers solve the video decoding flaws, TV manufacturers are certainly willing to choose more powerful partners. Morningstar, Jingchen, Rockchip and other chip makers want to start thinking in times of peace, although currently occupy most of the market, sitting on the most powerful TV chip, but can not sit idly by someone else to grab business, really to the mobile phone, TV chip two When they are united, what kind of competitiveness should traditional TV chip manufacturers have? Cost-effective? Ha ha……
