Generalized Hybrid Intra and Wyner-Ziv Video Coding

Abstract

The hybrid Wyner-Ziv (WZ) and intra video coding system has many interesting features, like the possibility to perform real motion estimation, at the decoder, and low latency coding. In this letter, we present an improved system and we will generalize it to include the other types of WZ coding. Thus, we propose a new quantization and a new cyclic redundancy check checking technique and, most importantly, we propose many new coding modes to produce a more efficient system that exploits the strong features of each type. The resulting system can thus produce many types of hybrid frames and allows mode adaptive coding. The simulation results show an improvement of the rate-distortion efficiency and can largely outperform those of state of the art.
