面向3D高清的国家广电行业标准AVS+较大地提高了编码效率，但也增加了编码复杂度，并行编码技术是解决高复杂度编码器的有效方法。该文改变了传统视频编码的反馈环，提出一种新的视频并行编码框架，有效地实现了编码的并行化；并将该框架应用于AVS+实时编码器中，实现了一种基于AVS+实时编码的并行算法。实验结果表明，该算法充分发挥多核处理器的运算能力，在编码性能损失极小，编码延迟可控的条件下极大地提高了视频编码速率。

The national TV industry standard AVS+, which faces the demand of 3D and high definition, got a high progress in coding efficiency, but it also increases complexity. Parallel coding technique is an efficient solution to deal with high-complex encoder. A new parallel video coding framework is proposed by changing the traditional video coding back feed loop to realize efficient parallel coding. The framework is applied to the AVS+ real-time encoder, and implements a parallel video coding algorithm based on AVS+real-time coding. Experimental results demonstrate that, the algorithm makes full use of the computing ability of the multi-core processor, and improves the video coding rate significantly.
