Why is Qualcomm's chip no match for an unknown TV chip?

Some people say that since it is a chip used in mobile phones, it is not feasible to take advantage of the Snapdragon 810. The smart TV market is not much smaller than the mobile phone market, Qualcomm naturally will not have no sensation. Previously, Qualcomm had released TV chips Xiaolong 600 and Xiaolong 802. Naturally, there was no doubt about its performance. However, Xiaolong 802 was halted after 5 weeks, just because Xiaolong 802 was not as expected by Qualcomm. Regain the advantages of the TV market.

Hard decoding is more suitable for mobile phones and smart TVs

However, in terms of performance, Qualcomm has to say that it is second, naturally, no one can confidently call it first. But in video decoding, Qualcomm seems to have not really prepared for the smart TV market. Video decoding is divided into hard decoding and soft decoding. Soft decoding is just like on a computer. Pure computing performance is used to process video decoding. 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, and hard decoding power consumption is very small (this is very important for mobile phones and televisions), and the cost is extremely low (as opposed to the equivalent decoding Capability 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-stream high-definition video smoothly. At this time, the dedicated decoding circuit helps a lot.

Qualcomm's processor, integrated Adreno series GPU, which must be extra plug-in 4K solution DSP chip, will make the 4K playback normal, external DSP chip after the Xiaolong 600 does not support 4K playback The inconvenience of the circuit scheme is complicated and the cost is increased, which is 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 alone, 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.
