Evaluation of Tile-based Parallelism in VVC Encoders for 360-degree Videos

Year: 2025

Type: conference-paper

Abstract: This work evaluates the parallelism potential and the coding efficiency of Tile-enabled encoding of 360-degree videos for the Versatile Video Coding (VVC) standard. Six 4K conventional videos and eight 360-degree videos were tested with various tile configurations. The results showed that increasing the number of tiles led to speedup gains, with a maximum speedup of 15.52. However, coding efficiency, measured by BD-Rate, generally increases as the number of tiles increases.The results suggest that while both video types benefit from tile configurations, optimal configurations provide better speed gains and less degradation in coding efficiency, particularly in 360-degree videos.
