Combining tile parallelism with slice partitioning in video coding
(2018)Tiles and slices provide different frame partitioning options. While they can both be used for video coding parallelization, tiles offer better scalability to the number of available processors, especially as far as video ... -
Evaluation of heterogeneous scheduling algorithms for wavefront and tile parallelism in video coding
(2019)Video is by far the “biggest” Big Data, stretching network and storage capacity to their limits. To handle the situation, video compression has been an active field of study for many years, producing output of huge commercial ... -
A Fast Heuristic for Tile Partitioning and Processor Assignment in Hevc
(2018)As the compression efficiency of HEVC comes at the cost of high complexity, especially in the encoder's side, improved parallelization techniques that will speedup the encoding process are essential. One of the parallelization ... -
Heuristics for tile parallelism in HEVC
(2017)HEVC has emerged as the new video coding standard promising increased compression ratios compared to its predecessors. This performance improvement comes at a high computational cost. For this reason, HEVC offers three ... -
On evaluating the impact of tile partitioning in AV1
(2018)The advent of 4K and 8K resolutions in cameras and TV sets, posed a challenge to Video on Demand (VoD) and live streaming industry since the network overhead compared to FullHD was multiplied. For this reason, new video ... -
On improving the speedup of slice and tile level parallelism in HEVC Using AVX2
(2017)HEVC has emerged as the new video coding standard promising improved compression ratios (for the same quality) by up to 50% compared to H.264/AVC. To achieve this performance HEVC requires increased computational overhead ... -
On the Evaluation of Coarse Grained Parallelism in AV1 Video Coding
(2018)Video compression is arguably one of the most time consuming tasks, especially at high resolutions. For this reason parallelization has been used at various levels: from coarse grained schemes that consider groups of blocks ...
