Abstract

Se describe un método de decodificación de un flujo de bits de video o imagen implementado por un dispositivo de decodificación, en donde el flujo de bits incluye datos que representan una capa de codificación de video actual, el método comprende cuando se determina que la capa de codificación de video actual es la única capa en el flujo de bits, usando el identificador de una unidad NAL de la capa de codificación de video actual como el identificador de la capa de codificación de video actual.
