Standard: MPEG-5
Part: 2

Specification of a data stream structure defined by two component streams, a base stream decodable by a hardware decoder, and an enhancement stream suitable for software processing implementation with sustainable power consumption. The enhancement stream will provide new features such as compression capability extension to existing codecs, lower encoding and decoding complexity, for on demand and live streaming applications.

Edition - 1: Low Complexity Enhancement Video Coding

Publication Year: 0
Status: published
Motivations: There is a commercial need for a lightweight video codec that has better coding performance while also being low complexity. Such a coding technology would fit a niche where an existing video decoder with the addition of a small amount of additional technology could provide substantial improvements.
Objectives: The objective of this project is to develop a standard that leverages existing deployed MPEG video codecs in a manner that improves video compression efficiency while keeping the incremental technology complexity impact low. Target platforms for deployment would be a software codec or existing hardware codec with extra processing capability. Examples could be Set Top Boxes (STB), mobile devices and PC-based decoders. An additional benefit is the reduction in implementation complexity or a corresponding expansion in spatial resolution.
