TITAN: Tile Timing-Aware Balancing Algorithm for Speeding Up the 3D-HEVC Intra Coding

Abstract

This paper presents the Tile Timing-Aware balancing algorithm (TITAN) for speeding up the 3D-High Efficiency Video Coding (3D-HEVC) video encoding. The design of the TITAN algorithm is based on the premise that the encoding time of tiles partitioning of neighbor frames are similar. Therefore, based on the encoding time of the last-encoded frame, TITAN controls the tiles boundaries aiming to maximize the balance among tiles. Our software evaluation with TITAN implemented in 3D-HEVC Test Model 16.0 achieved an average of 6.2% higher speedup compared to the uniform-sized tiles. This is the first work in the literature proposing to speed up the 3D-HEVC video encoding by balancing the tiles workload.
