Abstract

resumo “indicação de uso de processamento paralelo de onda dianteira em codificação de vídeo” um codificador de vídeo gera um fluxo contínuo de dados que inclui um elemento de sintaxe que indica se uma imagem é codificada de acordo com qualquer um de um primeiro modo de codificação ou um segundo modo de codificação. no primeiro modo de codificação, a imagem é totalmente codificada utilizando processamento paralelo de onda dianteira (wpp). no segundo modo de codificação, cada mosaico da imagem é codificado sem usar wpp e a imagem pode ter um ou mais mosaicos. um decodificador de vídeo pode analisar o elemento de sintaxe do fluxo de bits. em resposta a determinação de que o elemento de sintaxe tem um valor particular, o decodificador de vídeo decodifica a imagem inteiramente usando wpp. em resposta à determinação de que o elemento de sintaxe não tem o valor particular, o decodificador de vídeo decodifica cada mosaico da imagem sem o uso de wpp.
