A foveated image transmission and compensation method with a rendering compression is proposed to reduce the data transmission bandwidth and rendering effort, resulting in a power saving without causing visual artifacts. The method was implemented and tested on an FPGA-based headset tester equipped with a high-accuracy eye-tracking system. The foveation zone division was determined through a review of human factors experiments.

An anti-aliasing image reconstruction for foveated transmission in VR/AR microdisplays is presented, which can efficiently reduce transmission bandwidth by varying downsampling ratios across different image zones. Unique scale and slope parameters per position dynamically adjust the bilateral filter and bicubic interpolation in the optical coordinate system, enhancing detail preservation and minimizing aliasing artifacts.
51.3 - Invited Paper: Optimization of XR Foveation with Coding Unit Rearrangement (9:40 AM - 10:00 AM)

The authors introduce a scheme for decompressing received bitstreams with coding unit rearrangement for foveation display. This method effectively reduces flicker risk in single image mode. In dual image mode, this proposed scheme significantly optimizes GRAM size and latency in DDIC, enhancing overall display performance.
51.4 - Invited Paper: High-Refresh-Rate 8K+ Display System with 80% Bandwidth Savings (10:00 AM - 10:20 AM)

Sub-area control scanning technology aligns with human visual perception, significantly reducing data transmission by 80% without compromising clarity in the viewing area. A VR solution with this technology can achieve monocular 4K4K (binocular 8K) resolution, utilizing eye tracking for gaze-focused high-definition rendering while minimizing computing and bandwidth demands.
