JVET-AM0325 AHG18: BD-PSNR as alternative evaluation metric for ultra-low latency test scenario [M. Sychev, K. Malyshev, S Ikonin, E. Alshina (Huawei)] [late]
This informational proposal provides an example of usage Bjontegaard (BD-PSNR) metric for ultra-low latency (ULL) test scenario investigated by AhG18 and test conditions proposed in JVET-AL0176. The BD-PSNR results comply with observed quality improvement for results obtained in ULL evaluation. Documents demonstrate the behavior of BD-PSNR and BD-rate for some corner cases.
Some test successfully passing video through the channel without freezes which leads to horizontal curves with similar value which is critical for BD-Rate calculation due to vertical integration, but BD-PSNR succeed in all of such cases. This allows to avoid “#VALUE” in excel tables and to obtain average single number of obtained results.
For further study in AHG – see notes under JVET-AM0109 and JVET-AM0202.
