What does the soft and hard solution mean in the network TV box settings?

The question is from the znds forum.

Q: What is hard solution?

A: Hard decoding is to be completed by a special decoding chip in the machine, the quality depends on the technical ability of the manufacturer, some manufacturers have strong technical strength, compatibility and decoding effect is better, and some manufacturers have slightly poor technical strength, compatibility and decoding effect is not satisfactory.

Q: What is SoftSolution?

A: Soft decoding is to use CPU to decode, which requires strong CPU performance and processing power, but the compatibility of convection ** format is better, because the soft decoding library is developed by ourselves, and we can control the quality.

Q: Is it better to solve hard or soft solutions?

A: Generally speaking, the image quality of the hard decoding will be better, because the hard decoding has a special chip to decode with high efficiency, which will theoretically be better than the soft decoding, but due to the different technologies of different chip manufacturers, the hardware decoding may not be as compatible with the code stream as the soft decoding, so there will be some live broadcast sources that the hardware decoding cannot be ** but the soft decoding can.

Q: Why do I only have a hard solution but no soft solution?

A: Because your box only supports hard decoding, not soft decoding mode!

Q: Why does my device only have a hard decoder but no soft deco?

A:This is caused by the lack of decoding of your device's CPU performance (especially Xiaomi box),Taijie**The soft decoding needs to have a neon instruction to use,The application will check whether the device's CPU still has a neon instruction,If not, the soft decoding will not be displayed,So you can only see the hard decoding method。

The hardware is an external link device, and the software is a built-in system.

The software and hardware decoding of smart TVs refers to hardware decoding and software decoding respectively.

In everyday life, codecs are used in a wide range of applications. For example, in *** (MPEG-2), in VCD (MPEG-1), in various satellite and terrestrial television broadcasting systems. On the Internet, footage is usually compressed using a variety of different codecs, and in order to be able to view the footage correctly, users need to install codecs.

Expand the resources of this potato hail feed:Hardware code advantages:

It is more power-saving, suitable for long-term mobile devices and live broadcasts, and in the case of limited battery, it will be better to use hardware decoding. Reduce the CPU usage, and you can give the cup to other threads, which is conducive to improving the fluency.

Soft decoding advantages:

With better adaptability, software decoding mainly occupies the operation of CUP, soft decoding does not consider the hardware decoding support of the community, you can use the CPU, but the hand macro uses more CUP, which means that Senfan is very performance-consuming, very power-consuming, in the case of sufficient equipment power, or in the case of insufficient hardware decoding support of the device, it is better to use software decoding.

The soft and hard decoding of smart TV refers to the technology of decoding the ** signal,Soft decoding refers to the use of CPU to complete the decoding process,Hardware decoding is completed through a special hardware acceleration module (such as GPU、VPU, etc.) to complete the decoding process。

The difference between soft and hard decoding is the way of processing. Soft decoding needs to use the TV's own CPU for calculation,It consumes more resources and power sensitivity,And hard decoding can use the hardware module of the special Zhongzen to complete the decoding bridge training,More efficient、Power saving、Smooth。

The software and hardware decoding of smart TVs refers to hardware decoding and software decoding respectively.

It's the same thing as PC software and hardware desolation. Soft decoding, CPU decoding, high requirements for CPU, if the CPU is not strong, there will be jamming, but the compatibility is good; Hard decoding, display chip decoding, decoding speed is fast, but the compatibility is not as good as soft decoding.

Soft decoding is to use the software's own decoder to decode with good fluency Hard decoding is to use the set-top box's own hardware decoder to decode, but the network requirements are high, and the network may be stuck if the network is not good.

The soft solution means that it will not work at any time, and the hard solution is to crack it directly in one step.
