Multi-core Parallel Video Coding Algorithm Based on AVS+Real-time Encoding

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.
