MCTF and scalability extension of H.264/AVC

Abstract

The extension of H.264/AVC hybrid video coding towards motion-compensated temporal filtering (MCTF) and scalability is presented. Utilizing the lifting approach to implement MCTF, the motion compensation features of H.264/AVC can be re-used for the MCTF prediction step and extended in a straightforward way for the MCTF update step. The MCTF extension of H.264/AVC is also incorporated into a video codec that provides SNR, spatial, and (similar to hybrid video coding) temporal scalability. The paper provides a description of these techniques and presents experimental results that validate their efficiency.
