Abstract
método e aparelho para intrapredição. dispositivos e métodos para intrapredição de modo de intrapredição dc são fornecidos. o método inclui: obter um valor de um índice de linha de referência intrapredição de um bloco de transformada; obter amostras de predição do bloco de transformada com base em amostras de referência a partir de uma linha de referência. a linha de referência é indexada pelo valor do índice de linha de referência intrapredição. o método introduz uma harmonização de mrl e intrapredição não direcional (ou seja, dc). a harmonização consiste em alinhar as amostras de referência a partir de uma linha de referência, que é indexada pelo valor do índice de linha de referência de intrapredição.
