Subjective and Objective VQA of Video Codecs for UHD Video Streaming

Year: 2024

Type: conference-paper

Abstract: In this work, we conduct a subjective video quality assessment (VQA) experiment to evaluate the performance of modern video codecs when displayed on a large (30sqm) ultra-high-definition (UHD) video wall. Our comparative study involves four encoding standards: Advanced Video Coding (AVC) / H.264, High-Efficiency Video Coding (HEVC) / H.265, Versatile Video Coding (VVC) / H.266, and AOMedia Video 1 (AV1). Moreover, the study includes the evaluation in terms of correlation performance of a set of widely used full-reference objective VQA metrics against the subjective scores. Our results showcase the perceptual superiority of the VVC over rival encoding standards, aligning with the objective quality assessment and relevant literature.
