Abstract

Se proporciona un método en una codificación de imagen y/o una decodificación de imagen, en el que se introducen entradas de cabecera de imagen para CCALF que define los datos CCALF comunes y todos los sectores pueden heredar esta información común. Se reduce la sobrecarga de señalización, en particular, la sobrecarga de la cabecera de sector (en términos de número de bits).
