What is the difference between hard decoding and soft decoding?

What is the difference between hard decoding and soft decoding? In the past few years, smart projector products with built-in systems have emerged in an endless stream. For the household, commercial, educational, entertainment and other fields, the products launched by various manufacturers can be described as varied. In addition to the basic functions of projecting large screens, smart projection can be used independently as an entertainment and gaming device. Among them, audio-visual entertainment is particularly popular with consumers.

What is the difference between hard decoding and soft decoding? What is the role in the projector?

• The difference between soft decoding and hard decoding can literally be understood as one implemented by software driver and one implemented by hardware.

Hardware decoding: Hardware decoding is easy to understand from the literal meaning, that is, decoding the video through hardware, in which hardware decoding is performed by the GPU.

Software decoding: Software decoding is decoding through the CPU occupied by the software itself. The difference between decoding and soft decoding:

1. Hard decoding is implemented by GPU, usually hardware; Soft decoding is handled by CPU;
2. Video played by hard decoding is smoother; Soft decoding will increase CPU workload, increase power consumption, not smooth playback, or even crash.

Hard decoding requires relatively high system configuration of the projector. The network sources are getting clearer and the bit rate is getting higher and higher. So it should be said that supporting hard decoding should be the direction of micro projectors with built-in systems in the future. At the same time as more and more high-quality video resources appear, it also puts forward higher requirements for the performance of device decoding, as is the case with smart projectors, and with other products.
