在本文中，我们描述了正在开发的高效视频编码(HEVC)标准的加密可能性。列出了加密后保持HEVC兼容性的比特流元素，并描述了它们对视频适配的影响。从该列表中选择三个比特流元素，即帧内预测模式差、运动向量差符号和残差符号。这些元素提供了对视频信息的良好保护，并且由于其等概率熵编码特性而导致0.0%的Bjontegaard增量比特率增加。
In this paper, we describe encryption possibilities for the High Efficiency Video Coding (HEVC) standard under development. Bitstream elements which maintain HEVC compatibility after encryption are listed and their impact on video adaptation is described. From this list, three bitstream elements are selected, namely intra prediction mode difference, motion vector difference sign, and residual sign. These elements provide good protection of the video information and result in 0.0% Bjontegaard delta bitrate increase because of their equal probability entropy encoding property.
