Abstract

atribuição de modulação de código de pulso de domínio residual quantizado com base em bloco para derivação de modo de intra-predição. as técnicas são descritas para melhorar a codificação de vídeo. por exemplo, um primeiro bloco de uma imagem incluída em um fluxo de bits de vídeo encodificado pode ser obtido. um segundo bloco da imagem pode ser determinado como sendo codificado (por exemplo, encodificado) usando um tipo de modo de modulação de código de pulso de domínio residual quantizado com base em bloco (bdpcm), como modo de bdpcm vertical ou modo de bdpcm horizontal. no evento o segundo bloco é codificado usando o modo de bdpcm vertical, um modo de intra-predição vertical pode ser determinado para uma lista de modo de intra-predição para o primeiro bloco. o modo de intra-predição vertical pode ser adicionado à lista de modo de intra-predição para o primeiro bloco. no evento o segundo bloco é codificado usando o modo de bdpcm horizontal, um modo de intra-predição horizontal pode ser determinado para a lista de modo de intra-predição para o primeiro bloco e o modo de intra-predição horizontal pode ser adicionado à lista de modo de intra-predição.
