Authors: Han Huang Qualcomm Vadim Seregin Qualcomm Marta Karczewicz Qualcomm
Abstract
This contribution reports the test results of EE2 Test 2.1. In Test 2.1a, the number of active reference pictures in random access configurations is increased to the number of available reference pictures, and encoder fast algorithm is applied. It reports -0.21%, -0.25%, -0.32 BD-rate with 102% encoder time and 98% decoder time. In Test 2.1b, the block level reference picture reordering method is tested. It reports -0.10%, -0.10%, -0.08% BD-rate with 101% encoder time and 101% decoder time in random access, and -0.29%, -0.39%, -0.55% BD-rate with 103% encoder time and 107% decoder time in low delay B configurations. In Test 2.1c, the block level reference picture reordering method is tested with the increased number of active reference pictures. It reports -0.31%, -0.37%, -0.38% BD-rate with 102% encoder time and 101% decoder time in random access configurations.
