摘要

Wyner-Ziv视频编码提供了一种新的低复杂度视频编码范式。然而，Wyner-Ziv范式在解码器端积累了很高的复杂性，这可能会给有延迟要求的应用程序带来困难。另一方面，技术进步为我们提供了支持并行数据处理的新硬件。本文提出了一种基于多核处理器的更快的Wyner-Ziv视频解码方案。通过这种方式，每个帧通过多个处理单元之间的协作进行解码，实现了高达71%的时间减少，而没有明显的速率失真下降损失。

Wyner-Ziv frame parallel decoding based on multicore processors

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.
