Abstract :
Wyner-Ziv video coding paradigm provides a framework where most of complexity is moved from the encoder to the decoder. In this way, Wyner-Ziv coding support efficiently multimedia services for low complexity devices which have to capture, encode and send video. Aplications such as mobile phones, sensor, Personal Digital Assistant (PDA) could benefice to this paradigm. On contraty to tradicional video paradigms, the complexity of the decoder is quite high and it should be reduced. This work presents a parallel Wyner-Ziv decoding algorithm in aims to reduce its high complexity. The present approach efficiently distribute the burden of the complexity over the number of cores which are available in the architecture. By using this parallel approach, the decoding time is reduced around 73%. The proposed methods are scalable for any multicore architecture and adaptable for different Wyner-Ziv decoding schemes.
