| Abstract: |
This paper presents and discusses an objective performance evaluation of two lines of development for the next generation of video coding schemes: AV1 of the Alliance for Open Media (AOM) and JEM of the Joint Video Exploration Team (JVET). Their predecessors and finalized schemes, i.e., VP9 for AV1 and High-Efficiency Video Coding (HEVC) for JEM, serve as the reference for this evaluation process. The compression efficiency results indicate an improvement in terms of BD-rate of about 20% for AV1 and about 30% for JEM, respectively, relative to their predecessors. However, this analysis also reveals different trade-offs between encoder run time and compression efficiency. While the JEM encoder requires a factor of about 11 in run time relative to the HEVC reference implementation HM, the corresponding factor for the AV1 encoder is about 36x relative to VP9. When comparing the coding schemes among each other, the current version of AV1 performs worse than HM with a bit-rate overhead of about 9.5% while requiring almost twice the run time of the JEM encoder or 20x the run time of HM. |
