Abstract

intraprevisão é usada em padrões de codificação de vídeo de tecnologia de ponta, tal como avc. os modos de intraprevisão são codificados no fluxo contínuo de bit. componentes luma e croma podem ter, potencialmente, diferentes modos de previsão. para componentes croma, há 7 diferentes modos definidos em avc: vertical, horizontal, dc, direções diagonais e "igual a luma". estatística mostra que o modo "igual a luma" é frequentemente usado, mas, em avc, esse modo é codificado usando mais bits que outros modos durante a codificação de entropia, portanto, a eficiência da codificação diminui. desta maneira, uma atribuição de binarização/palavra código modificada para sinalização no modo intracroma pode ser utilizada para codificação de vídeo de alta eficiência (hevc), o padrão de codificação de vídeo da próxima geração.
