AHG10/AHG12: Enhanced reference picture structures for ECM and VTM
Authors: K. Andersson Ericsson Rickard Sjöberg Ericsson Ruoyang Yu Ericsson Lukasz Litwic Ericsson
Abstract
This contribution suggests a modified reference picture lists setting for ECM/VTM random access to store more pictures in the allowed Decoded Picture Buffer (DPB). The proposal also includes a change to the QP value for two pictures in the GOP. This is claimed to be almost identical to the settings proposed for VTM in JVET-Y0126 with the addition to order active entries in L0 and L1 such that pictures closer to the current picture in terms of POC are earlier in the lists.
