Abstract

Se describen ejemplos de métodos y aparatos de codificación de video y métodos y aparatos de decodificación de video. Un método de procesamiento de video ejemplar incluye realizar una conversión entre un video y un flujo de bits del video de acuerdo con una regla, en donde el flujo de bits incluye unidades de capa de abstracción de red (NAL) para múltiples capas de video de acuerdo con una regla; donde la regla define que un proceso de extracción de subflujo de bits para generar un flujo de bits de salida que comprende un conjunto de capas de salida (OLS) incluye una o más operaciones que se realizan selectivamente respondiendo a las siguientes condiciones: (1) una lista de valores de identificador de capa de encabezado de unidad NAL en OLS no incluye todos los valores de identificador de capa de encabezado de unidad NAL en todas las unidades NAL de capa de codificación de video (VCL) en el flujo de bits, y (2) el flujo de bits de salida que contiene una unidad NAL de información de mejora complementaria (SEI) que contiene un mensaje SEI de anidamiento escalable.
