摘要： 根据H.264 这一新的视频压缩标准的特点，利用Intel 的超线程技术以及OpenMp，可以使软件编码器进行线程级的并行运算，从而大大提高编码速度。该文对超线程技术、OpenMp 以及编码过程中不同级别的并行运算进行了分析。证明了利用OpenMP 对H.264 编码器进行并行处理优化，再加上具有超线程技术的处理器的支持，必将会大大提高编码器的性能。

Abstract: According to characters of the H.264 video encoder, this paper analyses frame-level, slice-level and block-level parallel algorithms, and also introduces the Intel hyper-threading technology and OpenMp. It proves that the performance of the encoder can be greatly improved by using OpenMP to optimize parallel process of H.264 encoder, and by the support of hyper threading processor
