This paper presents an energy evaluation of the HEVC decoding process considering different encoding configurations in order to provide support for efficient encoding-for-decoding solutions. The analysis evaluates the energy impact of changing the configuration of four encoding tools in the HEVC decoding process. A set of six different configurations are used to encode/decode video sequences in order to evaluate the energy behavior of the HEVC decoding process. As results, we found that the energy saving behavior for each evaluated configuration on the decoding side is different from the encoder. Besides, the video sequence content is much more relevant for the decoder energy behavior than for the encoder. Finally, we show that the energy behavior of each evaluated configuration varies for different numbers of decoding events.
