51‐3: Invited Paper: Optimization of XR Foveation with Coding Unit Rearrangement

Abstract

Foveation has two methods: single image mode and dual images mode. For the former, SOC transmits the compressed image consists of different low‐resolution blocks, some of which have very large differences after up‐scaling may cause flickering risks when displayed. For the latter, SOC processes the compressed periphery and foveated images sequentially, therefor DDIC uses large GRAM to cache these bitstreams, which will also introduce huge latency. In order to solve these problems existing in two modes, this paper presents a scheme to process the image or compressed bitstreams with coding unit rearrangement.
