Abstract

La presente invención se refiere un método y aparato de codificación/de codificación de imagen para señalar u VPS y un medio de grabación que almacena un flujo de bits. Un método de decodificación de imagen puede comprender obtener primera información que indica si cada conjunto de capa de salida (OLS) especificado por un conjunto de parámetro de video (VPS) incluye solamente una capa, obtener segunda información que indica el número de estructuras de sintaxis de parámetro de búfer de imagen decodificada (DPB) en el VPS, basado en la primera información, obtener las estructuras de sintaxis del parámetro DPB en el VPS basado en la segunda información, y gestionar un DPB basado en las estructuras de sintaxis del parámetro DPB.
