Description of Core Experiment 5 (CE5): Arithmetic Coding Engine
Abstract
This Core Experiment (CE) covers two aspects related to the arithmetic coding engine of VVC. The first aspect addresses the effect on the compression efficiency of training parameters of the probability estimation stage of the proposed arithmetic coding engines. The parameters to be trained include the context model initialization values as present in the current VTM software as well as the so-called customized window sizes as present in some of the proposed entropy coding engines. The second aspect addresses the achievable throughput in software and hardware implementations.
JVET-L1025 Description of Core Experiment 5 (CE5): Arithmetic Coding Engine [H. Kirchhoffer, A. Said]
This CE was planned to study alternative arithmetic coding engines and customized window sizes.
It was commented that including the bypass bins in the throughput testing seemed unnecessary and complicates the model. The bypass processing is the same for all cases. It was agreed to remove that aspect.
