摘要：
With the aim of providing low complexity encoders, Wyner-Ziv video coding provides a new paradigm where the complexity of the encoder is moved to the decoder. However, this high decoding complexity could involve a problem in some applications which have delay restrictions. Nowadays parallel computing is a growing field into the computation market. In particular, most of personal computers and hardware for video coding includes multicore processors, which allows a parallel execution by means of several independent cores in a same chip. As a consequence, several DVC parallel decoding approaches are beginning to appear. This work proposes a parallel DVC decoding scheme for multicore processors, which decodes each GOP in an independent and parallel way. This scheme achieves above 70% time reduction without any rate-distortion penalty.
