Additional Tests for TV 3.0

TL;DR

This paper reports on additional subjective video quality tests for the TV 3.0 project, evaluating H.266/VVC and hybrid codecs at 4K resolution, with results comparable to previous experiments.

Contribution

It introduces new tests on 4K resolution using H.266/VVC and LCEVC codecs, maintaining consistent experimental protocols for comparability.

Findings

H.266/VVC at 4K shows specific quality metrics

Hybrid H.266/VVC+LCEVC codec performs effectively at 4K

Results are consistent with previous 720p to 4K tests

Abstract

In 2023 we have conducted extensive experiments on subjective video quality for the TV 3.0 project at University of Bras\'ilia. A full report on these tests is available at the F\'orum SBTVD website . These tests have evaluated the H.266/VVC codec and a hybrid codec formed by the H.266/VVC and the LCEVC (Low Complexity Enhancement Video Coding) with different resolutions, ranging from 720p to 4K. This report contains the results of additional tests performed for TV 3.0 performed at University of Bras\'ilia. This new experiment consists of two new Video Under Tests (VUTs), one with the H.266/VVC codec at 4K resolution, and the other with the H.266/VVC+LCEVC codec at 4K resolution. In this new test, both codecs have the same GOP size (120 frames) and use the same VVC encoder (MainConcept live encoder). This new experiment follows the same experimental protocol as the previous experiments, in order to be fully comparable to the reported results. This document details the results of the new experiments.
