It typically uses a standardized [[video compression]] algorithm, most commonly based on [[discrete cosine transform]] (DCT) coding and [[motion compensation]]. A computer [[software]] or [[computer hardware|hardware]] component that compresses or decompresses a specific video coding format is a [[video codec]].

Some video coding formats are documented by a detailed [[technical specification]] document known as a '''video coding specification'''. Some such specifications are written and approved by [[standardization organization]]s as [[technical standard]]s, and are thus known as a '''video coding standard'''. There are [[de facto standard|''de facto'' standards]] and formal standards.
