Abstract

Un dispositivo para decodificar datos de video incluye una memoria configurada para almacenar los datos de video y uno o más procesadores configurados para recibir un segmento de los datos de video, analizar un elemento de sintaxis de copia intra bloque (IBC) para determinar que un modo IBC está habilitado para el segmento, analizar un elemento de sintaxis de tipo de segmento asociado con el segmento para determinar que el segmento es un I segmento, y decodificar el segmento como un I segmento decodificando todos los bloques del segmento utilizando modos de codificación de intra-predicción.
