Abstract
resumo desblocagem de vídeo em modo de codificação intra pcm (ipcm) e sem perda as técnicas para codificação de dados de vídeo incluem a codificação de uma pluralidade de blocos de dados de vídeo, onde pelo menos um bloco dentre a pluralidade de blocos de dados de vídeo é codificado utilizando um modo de codificação que é um dentre um modo de codificação de modulação de código intrapulso (ipcm) e um modo de codificação sem perda. em alguns exemplos, o modo de codificação sem perda pode utilizar predição. as técnicas incluem adicionalmente a designação de um valor de parâmetro de quantização (qp) não-zero para o pelo menos um bloco codificado utilizando o modo de codificação. as técnicas também incluem a realização da filtragem por desblocagem em um ou mais dentre a pluralidade de blocos de dados de vídeo com base no modo de codificação utilizado para codificar o pelo menos um bloco e o valor qp não-zero designado para o pelo menos um bloco.
