Typically, a device that performs data Video compression is referred to as an encoder, and one that performs the reversal of the process as a decoder.
| FactSnippet No. 1,550,586 |
4.
The design of data Video compression schemes involves trade-offs among various factors, including the degree of Video compression, the amount of distortion introduced, and the computational resources required to compress and decompress the data.
