Abstract
codificador, decodificador e métodos correspondentes para predição intra. dispositivos e métodos para predição intra são fornecidos. o método inclui: obter um valor de informações de indicação de um bloco atual. quando o valor das informações de indicação indicar que o modo de predição intra do bloco atual não está compreendido no conjunto de modos mais prováveis, derivar o modo de predição intra intrapredmodey[ xcb ][ ycb ] do bloco atual pelas seguintes etapas ordenadas: i. intrapredmodey[ xcb ][ ycb ] é definido igual a intra_luma_mpm_remainder[ xcb ][ ycb ], ii. o valor de intrapredmodey[ xcb ][ ycb ] é incrementado em 1. o método pode aumentar a eficiência para determinar o modo de predição intra do bloco atual.
