摘要
H.264标准是目前压缩比率最高的视频压缩标准,但其计算复杂度高,编码效率较低.本文研究了H.264的编码原理及关键技术,引入CPU和GPU并行的编码框架,能有效地提高H.264的编码速度.
H.264 is the latest video coding standard which has the highest compression ratio,but the computational complexity greatly increases and its encoding efficiency is very low.This paper introduces the encoding principle and key technology of the H.264,and proposes a CPU＋GPU parallel decoder which can accelerate the encoding and decoding process significantly
