# What is rate distortion theory? - Compression Standard

### What is rate distortion theory?

- Distortion theory is about trade-offs between the rate and distortion.

- It is applied for compression schemes.

- An average number of bits are utilized to represent each sample value.

- If the rate of bits is decreased it is known as increase in distortion.

- If the rate of bits to represent each value is increased it is known decrease in distortion.
