Abstract

Se proporciona un método de decodificación. El método incluye recibir un flujo de bits que comprende una imagen codificada y un mensaje de información de mejora suplementaria (SEI), en donde el mensaje de SEI incluye parámetros de búfer de imágenes codificadas (CPB) correspondientes a las operaciones del decodificador de referencia hipotético (HRD) basado en la unidad de decodificación (DU) en subcapas; y decodificar la imagen codificada del flujo de bits para obtener una imagen decodificada. También se proporciona un método de codificación correspondiente.
