Abstract

processamento temporal para tecnologia de codificação de vídeo. um decodificador configurado para receber um primeiro vídeo de saída e um ou mais fluxos codificados adicionais, decodifica respectivos quadros dos um ou mais fluxos codificados adicionais para derivar respectivos conjuntos de residuais; e combinar os conjuntos de residuais com o primeiro vídeo de saída para gerar um vídeo de saída reconstruído. cada quadro é dividido em uma pluralidade de ladrilhos e cada ladrilho é dividido em uma pluralidade de blocos. para decodificar respectivos quadros, o decodificador é configurado para obter um conjunto preliminar de residuais dos um ou mais fluxos codificados adicionais, derivar um conjunto de predições temporais usando um armazenador temporal e combinar o conjunto de predições temporais com o conjunto preliminar de residuais. o decodificador é configurado para fornecer zeragem de valores do conjunto de predições temporais em um nível de quadro, em um nível de ladrilho e em um nível de bloco.
