Abstract

desabilitação da ocultação de dados de sinal na codificação de vídeo um codificador de vídeo pode determinar que a ocultação de dados de sinal é desabilitada para um bloco atual se o bloco atual é gerado usando a codificação com perda sem a aplicação de uma transformada aos dados residuais e o bloco atual é intra previsto usando um modo de intra-previsão no qual uma técnica de modulação de código de pulso diferencial residual (dpcm) é usada
