The video decoding chip is the chip that completes the video decoding
We know that video recording is analog digital (PCM) and then digital
However, the amount of data after PCM is too large, and many redundant direct transmission wastes bandwidth
It is usually encoded (using redundancy) before transmission is decoded and displayed at the receiving end
Such as MPEG-1, 2, 4 encoding H.263H.264 encoding
The chip that completes the corresponding codec specification is called the video codec chip
For example, Philip Fujitsu HP has a corresponding chip
