Compression

Abstract

The Compression subgroup of the Task Force was set up to provide guidance for the longterm integration of compression into programme production. Its work led to the conclusion that there is no single member of a compression family that satisfies the requirements of a fully-networked digital production facility. The two compression families ultimately selected by the subgroup were MPEG and DV, each of which offers individual trade-offs in terms of coding flexibility, product implementation and system complexity. This article gives an overview of the factors which led to this choice.
