Abstract

Un dispositivo de procesamiento de video está configurado para obtener, desde una corriente de bits, uno o más elementos de sintaxis que indican uno o más esquemas de partición para un conjunto de capas de salida; para cada esquema de partición respectivo de uno o más esquemas de partición, el esquema de partición respectivo especifica una división del conjunto de capas de salida en una o más particiones; cada capa en el conjunto de capas de salida pertenece exactamente a una partición en el esquema de partición respectivo; adicionalmente, el dispositivo de procesamiento de video obtiene, desde el mensaje de Información de Mejora Complementaria (SEI) o información de utilidad de video (VUI) en un conjunto de parámetros de video (VPS), parámetros de decodificador de referencia hipotética (HRD) para cada uno de uno o más esquemas de partición; para cada partición respectiva del esquema de partición respectivo, el dispositivo de procesamiento de video prueba, con base en los parámetros HRD para el esquema de partición respectivo, la partición respectiva para conformidad a una norma de codificación de video.
