论文摘要
本文提出了一种新颖的算法，旨在通过利用HEVC-二十座溶液的一般能量模型来最大程度地降低所需的解码能量。我们将能量模型纳入HEVC编码器中，以便它能够构建一个位，其解码过程比传统位流的解码过程所消耗的能量少。为了实现这一目标，我们建议将传统的利率限制进度方案扩展到解码能量率降低方法。为了在优化过程中获得快速编码的决策，我们在量化参数与Lagrange乘数之间得出了固定的关系以进行能量优化。我们的实验表明，此概念适用于框内编码的视频，对于本地播放以及在线流媒体方案，可以节省多达15％的解码能量，而牺牲比特率的增加幅度大致相同。
This paper presents a novel algorithm that aims at minimizing the required decoding energy by exploiting a general energy model for HEVC-decoder solutions. We incorporate the energy model into the HEVC encoder such that it is capable of constructing a bit stream whose decoding process consumes less energy than the decoding process of a conventional bit stream. To achieve this, we propose to extend the traditional Rate-Distortion-Optimization scheme to a Decoding-Energy-Rate-Distortion approach. To obtain fast encoding decisions in the optimization process, we derive a fixed relation between the quantization parameter and the Lagrange multiplier for energy optimization. Our experiments show that this concept is applicable for intraframe-coded videos and that for local playback as well as online streaming scenarios, up to 15% of the decoding energy can be saved at the expense of a bitrate increase of approximately the same magnitude.
