Abstract(s)
Este trabalho apresenta um estudo de streaming de vídeo, o qual pode utilizar técnicas de adaptação de qualidade implementado com protocolo HTTP. Existem diversas técnicas para codificar o vídeo para que se possa criar um streaming, entre elas existem MPEGDASH, HLS e o MMT, que são estudadas neste trabalho. Com uma particularidade do MPEGDASH que foi utilizado no estudo de caso. Este trabalho apresenta também uma visão do ATSC 3.0, padrão já utilizado na Coreia do Sul e que faz uso de alguns segmentos do MPEGDASH, denominado ROUTE/DASH. O estudo de caso apresenta resultados de comutação de banda, que possibilita a visualização da mudança de imagem codificada em MPEGDASH.
This paper studies video streaming, that can use techniques of adaptive streaming over HTTP. There are different video coding techniques that can be use on video streaming, among them there are MPEG-DASH, HLS and MMT, which are studied in this paper. However only MPEG-DASH is tested in this paper. This paper still presents a little about ATSC 3.0, standard already used South Korea, which also use some pieces of MPEG-DASH coding, that is named ROUTE/DASH. The test brings the results made by switching the bandwidth, which enable to see changes in image of the video coding with MPEG-DASH.
