Abstract :
Wyner-Ziv video coding presents a new paradigm which offers low-complexity video encoding. However, the Wyner-Ziv paradigm accumulates high complexity at the decoder side and this could involve difficulties for applications which have delay requisites. On the other hand, technological advances provide us with new hardware which supports parallel data processing. In this paper, a faster Wyner-Ziv video decoding scheme based on multicore processors is proposed. In this way, each frame is decoded by means of the collaboration between several processing units, achieving a time reduction up to 71% without significant rate-distortion drop penalty.
