摘要

High Efficiency Video Coding (HEVC) is the state-of-art-video coding standard which significantly improved the coding efficiency of a coded video signal with its preceding video coding standards. This paper presents technical aspects of HEVC thought objective and subjective performance analysis of different versions of HM software test models in different configurations in Main profile. We compared two models HM-16.12 and HM-16.6 through three fundamental parameters: signal-to-noise ratio, bit rate and time saving, while two test sequences in different resolutions are processed. Simulations results have shown that we have none, small or obvious differences in SNR values and bit rate, while encoding time saving is increased from 13,5% up to 48,3% depending on configurations and tested sequences. Beside objective results, subjective video assessments for all tested sequences and configurations are presented, too.
