Abstract

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