Abstract
modulação por código de pulso em diferencial de bloco de domínio de coeficiente em codificação de vídeo. um decodificador de vídeo pode determinar, com base nos elementos de sintaxe em um fluxo de bits que compreende uma representação codificada dos dados de vídeo, amostras quantizadas residuais de um bloco dos dados de vídeo. adicionalmente, o decodificador de vídeo pode determinar valores residuais quantizados com base nas amostras quantizadas residuais. após determinar os valores residuais quantizados, o decodificador de vídeo pode quantizar inversamente os valores residuais quantizados. o decodificador de vídeo pode gerar valores preditos realizando-se intrapredição para o bloco usando amostras não filtradas das amostras limiares de bloco superior ou esquerdo. adicionalmente, o decodificador de vídeo pode reconstruir valores de amostra originais do bloco cm baseo nos valores residuais quantizados inversamente e nos valores de predição.
