Abstract
With the growing demand for better compression efficiency, the JVET is studying on potential future video coding technologies that can significantly exceed the compression capability of the latest standard, Versatile Video Coding (VVC). In JVET, various methods improving the existing inter prediction modes in VVC have been being discussed and the extension of Geometry Partitioning Modes (GPM) is one of them. In this paper, we propose efficient signaling methods for the extended GPM modes in the Enhanced Compression Model (ECM), which is a reference software for the exploration activity beyond VVC, based on the experimental observation of the mode occurrence frequency. The experimental results show that the proposed methods give meaningful BD-rate gain compared to ECM.
