Abstract

Se describen ejemplos de métodos y aparatos de codificación de video y métodos y aparatos de decodificación de video. Un método ejemplar de procesamiento de video incluye realizar una conversión entre un video y un flujo de bits del video, en donde el flujo de bits incluye uno o más conjuntos de capas de salida que comprenden una o más capas de video de acuerdo con una regla de formato, en donde la regla de formato especifica que un mensaje de información de mejora complementaria, SEI, anidada no escalable, que incluye información con respecto al decodificador de referencia hipotética, HRD, es aplicable a todos los conjuntos de capas de salida que incluyen las mismas capas de video que el flujo de bits.
