JVET-Q0053 AHG13: Analysis of the Energy Demand and Time Complexity of Several Coding Tools in VTM-7.0 [M. Kränzler, C. J. Herglotz, A. Kaup (FAU)]

This contribution analyzes the influence of 9 coding tools on the decoding time and energy demand compared to the VTM-7.0 reference software. The analysis compares 2 tools with the All-Intra (AI) configuration and 7 tools with the Randomaccess (RA) configuration. It is reported that the overall decoding energy demand can both be increased and reduced by disabling a specific coding tool. For ALF, the decoding energy demand is reduced by approximately 7% with an increase of 4.36% in bit rate if the tool is switched off. For AMVR, the decoding energy demand is increased by 2.28% with a bit rate increase of 1.29%.
