Abstract
1/1 resumo reposicionamento dos blocos residuais de previsão na codificação de vídeo técnicas são descritas para codificar dados residuais de um bloco residual de previsão ou em um modo de codificação com perda ou em um sem perda, no qual uma transformada é pulada ou ignorada. as técnicas desta revelação incluem determinar quando reposicionar, ex., girar ou lançar, dados residuais de um bloco residual antes de codificar os dados residuais do bloco residual. para ambos os modos de codificação com perda e sem perda, um dispositivo de codificação de vídeo determina quando reposicionar dados residuais de um bloco residual com base em um modo de previsão do bloco residual e um tamanho do bloco residual. em alguns exemplos, as técnicas desabilitam o reposicionamento para todos os blocos residuais no modo de inter-previsão e modo de previsão de cópia intra bloco, e determinam reposicionar os blocos residuais no modo de intra-previsão quando os blocos residuais tem tamanho de blocos que é menor que ou igual a um tamanho limite.
