论文摘要
视频通信能源消耗的全球意义使有关视频编码的能源需求的研究促进了一项重要的任务。为此，通常需要一个专用的设置来测量编码和解码系统的能量。但是，这样的测量是昂贵且复杂的。为此，本文使用HEVC的X265编码器实现了详尽的测量系列的结果，并分析了编码时间与编码能量之间的关系。最后，我们引入了一个简单的编码能量估计模型，该模型采用了轻型编码过程的编码时间来估算复杂编码配置的编码能量。当在所有预设上平均时，提出的模型达到平均估计误差为11.35％。当需要编码能量估计以开发新的节能视频压缩算法时，这项工作的结果很有用。
The global significance of energy consumption of video communication renders research on the energy need of video coding an important task. To do so, usually, a dedicated setup is needed that measures the energy of the encoding and decoding system. However, such measurements are costly and complex. To this end, this paper presents the results of an exhaustive measurement series using the x265 encoder implementation of HEVC and analyzes the relation between encoding time and encoding energy. Finally, we introduce a simple encoding energy estimation model which employs the encoding time of a lightweight encoding process to estimate the encoding energy of complex encoding configurations. The proposed model reaches a mean estimation error of 11.35% when averaged over all presets. The results from this work are useful when the encoding energy estimate is required to develop new energy-efficient video compression algorithms.
