What does the code rate mean?

The code rate is the data transfer time of the unit time to transfer the number of digits, generally we use the unit is Kbps is thousands per second. The popular point of understanding is that sampling rate, unit time the larger the sampling rate, the higher the precision, the processing of the file will be closer to the original document, that is, the more details of the screen more rich.

Generally speaking, the larger the rate of the code, the closer the file is to the original file, but the file volume and the rate is proportional, so almost all coding format attention is how to use the lowest rate of code to achieve the least distortion, around this core derived from the CBR (fixed code rate) and VBR (dynamic code rate), Are all articles in this area.

Some principles about the rate of code:

1, the rate and quality is proportional to the volume, but the size of the file is also proportional to the rate of the code.

2, the rate is not the larger the better, when the rate of more than a certain number of the picture of the quality is not too big impact.
