摘要

本文提出了一种新的HEVC编码视频转码方法。该方法在不需要图像重建的情况下实现了非常快速的转码。它基于从比特流中去除精心选择的系数的原则。系数的移除是在比特流级别完成的，可以很容易地根据软件和硬件实现进行定制。该技术能够提供高达10%的比特率降低，图像质量降低约0.2-0.5dB。

Homogenous HEVC video transcoding by transform coefficient removal

In this paper, a novel method of transcoding of HEVC encoded video is presented. The novel approach enables a very fast transcoding without the need for the image reconstruction. It is based on the principle of removing of the carefully selected coefficients from the bitstream. The removal of coefficients is done on the bitstream level and can easily be tailored to software as well as hardware implementations. The technique is able to provide a bitrate reduction in the order of up to 10%, with the image quality decrease of about 0.2–0.5dB.
