Abstract

Se describen métodos y aparatos para el procesamiento de video, que incluyen codificación y decodificación. Un método de procesamiento de video de ejemplo incluye realizar una conversión entre un video y un flujo de bits del video de acuerdo con una regla de formato, en donde el flujo de bits incluye uno o más conjuntos de capas de salida (OLS), cada OLS que comprende una o más secuencias de video de capa codificada, y en donde la regla de formato especifica que un conjunto de parámetros de video indica, para cada uno de los uno o más OLS, un valor máximo permitido de un indicador de formato de croma y/o un valor máximo permitido de una profundidad de bits utilizada para representar píxeles del video.
