... the proposed rate control with QP refinement (PRC with QP refinement). We analyzed the performances of these three rate control schemes with JM 9.3 fixed QP (FQP) as bench- mark, where each of the ... different bit rates with JM 9.3 for fixed QPs ranged from 20 to 44 (the QPs were kept unchanged for all the frames). For the other three rate control schemes, the QPs in the...

In each case, the κ statistic was statistically significant, thus the null hypothesis is rejected and one can conclude that the level of agreement is higher than what is expecte...
