Avaliação do potencial máximo de speedup usando Tiles para compressão de vídeo paralela segundo o padrão HEVC

Abstract: Resumo-Este artigo apresenta uma análise da paralelização na compressão de vídeo de acordo com o padrão HEVC utilizando Tiles. Diferentes configurações de Tiles são avaliadas considerando duas variáveis principais: (1) speedup e (2) eficiência de compressão. Primeiro discutimos como as características do conteúdo podem influenciar na divisão da carga computacional utilizando a configuração de Tiles uniformes. Em seguida, vários vídeos são comprimidos utilizando diferentes configurações de Tiles para analisar o… Show more

“…In order to perform the workload prediction, the history of workload distribution is used. The authors of [11] conducted a study evaluating the maximum possible speedup achieved through dynamic tiling for a set of videos considering a set of tiling patterns. In order to perform this evaluation, the videos were encoded several times considering different parameters.…”

“…Most of literature works dealing with parallelism approaches of the HEVC encoder use Slices or Tiles to optimize the devices resources usage [6] [7], improve the user experience by either decreasing the coding efficiency loss caused by the use of Tiles [8] [9] or decreasing the framerate drops in video transmissions [10], or improve the parallelism by studying and better distributing the workload among the Tiles [11] [12] [13] [14]. Since the tiling tool is designed to enable parallel processing, we decided to follow in the direction of improving the speedup of using Tiles, therefore improving its main purpose.…”
