Title
(PT) conceito de codificação que permite o processamento parelelo, desmultiplexador de transporte e fluxo de bites de vídeo
Abstract
(PT) conceito de codificação que permite o processamento paralelo, desmulti-plexador de transporte e fluxo de bites de vídeouma carga útil de sequência de bytes em bruto, que descreve uma imagem em peda-ços, subfluxos ou placas wpp e codificada usando a codificação aritmética binária adaptativa de contexto, está subdivi-dida ou cortada em tranches com a continuação da adaptação de probabilidade de codificação aritmética binária adaptativa de contexto para além dos limites da tranche. através desta medida, os iimites da tranche adicional-mente introduzidos dentro de pedaços, subfluxos ou placas wpp não reduzem a eficiên-cia da codificação entrópica destes elementos. por outro lado. porém, as tranches são mais pequenas do que os pedaços originais, subfluxos ou placas wpp e podem respe-tivamente ser transmitidas mais cedo, isto é, com menos atraso do que as entidades originais não cortadas, isto é, os pedaços, subfluxos ou placas wpp. de acordo com outro aspeto, que pode ser combinado com o primeiro aspeto, as unidades nal de marcador de subfluxo são utilizadas dentro da sequência de unidades nal de um fluxo de bites de vídeo para permitir um desmultiplexador de transporte para atribuir dados de pedaços dentro das unidades nal aos correspondentes subfluxos ou placas, de modo a poder, em paralelo, servir de descodificador multi-roscado com os corre-spondentes subfluxos ou placas.
