COSMIC: A compatible scheme for moving image coding

摘要

This paper describes a video coding algorithm submitted for consideration by ISO/MPEG in the phase of its work targeted at bit-rates up to about 10 Mbit/s. Distinguishing features of the submission were the attempt to meet a wide range of requirements, rather than concentrating solely on picture quality, and compatibility with the earlier MPEG draft standard. This was achieved with a hierarchical structure with splitting in the pel domain. The reasons for this approach are explained and the impact on implementation complexity is also covered.
