EE2-related: Low complexity sign prediction
Authors: Cheung Auyeung Tencent Xinwei Li Tencent Shan Liu Tencent
Abstract
Sign prediction is a part of ECM-1.0. It was found to be one of the hot spot in ECM-1.0. This contribution proposes a method to reduce the computation of sign prediction in ECM-1.0. Using ECM-1.0 as reference and the common test conditions in JVET-V2017, the BDR of the proposed method for AI/RA is x.xx%/y.yy% The encoder time for AI/RA is x.xx%/y.yy%,. The decoder time for AI/RA is x.xx%/y.yy%. Results for LB shall be added when available.

Sign prediction is a part of ECM-1.0. It was found to be one of the hot spots in ECM-1.0. This contribution proposes a method to reduce the computation of sign prediction in ECM-1.0. Using ECM-1.0 as reference and the common test conditions in JVET-V2017, the BDR of the proposed method for AI/RA/LB is x.xx%/y.yy%/0.04% The encoder time for AI/RA/LB is x.xx%/y.yy%/98%,. The decoder time for AI/RA/LB is x.xx%/y.yy%/97%.

This had a rather small reduction in run time, incurring a small loss. It did not seem worthwhile to consider at this stage of the exploration.
