Optimized temporal scalability for H.264 based codecs and its applications to video conferencing

Abstract

In this paper, we describe and analyze a low complexity scalable video codec that extends our H.264-implementation DAVC. We can show that DSVC, our temporally scaled codec, attains an RD performance identical to the non-scaled version at comparable configuration. We achieve this by QP cascading, a method of assigning gradual refining quantization parameters… (More)
