Crosscheck of JVET-Y0105 (AHG10: An improved VVC rate control scheme)
Authors: Yifan Wang ByteDance Yang Wang
Abstract
This contribution reports the crosscheck results of JVET-Y0105 [1], which proposes some improvements based on the current R-lambda rate control algorithm. In JVET-Y0105, three methods are tested. Method 1 is the CTU-level bit allocation for skip and non-skip CTU. Method 2 is to set smooth window size based on the GOP size and Intra Period. In Method 3, the quality dependency factor (QDF) based rate control was extended to low frame rate. The simulation results match with those provided in JVET-Y0105.
