“…This problem is even worse when encoding a 3D video, requiring to process several views in parallel, rising the encoding effort due to the extra tools used for depth map coding [17]. Some works proposed depth map time-saving techniques for single-core systems [18][19][20][21][22][23]; however, their speedup gains do not allow real-time 3D video encoding. Our early works explored depth modeling mode one (DMM-1) parallelism under multicore [24] and GPU [25] architectures.…”

This paper analyzes the usage of tiles in 3D-High Efficiency Video Coding. We investigate the encoding impact of some tiles divisions using a Bjontegaard delta rate (BD-rate) on the common test conditions for 3D videos. This analysis demonstrated dividing the video into square tiles increases the encoding performance compared to non-square tiles (about 2.2%). In another analysis, we concluded the workload is highly unbalanced in the uniform distribution contributing to limit the speedup possibilities for the homogeneous multicore systems. Authors are not aware of any work focusing on balancing depth maps workload in tiles; therefore, we pointed out relevant studies and solutions for future projects in this open research area.
