Abstract

Un aparato configurado para codificar información de video que incluye una unidad de almacenamiento y un procesador en comunicación con la unidad de almacenamiento. La unidad de almacenamiento está configurada para almacenar información de video asociada con una capa base (BL) y una capa de mejora (EL), la BL tiene una imagen BL en una primera unidad de acceso, y la EL tiene una imagen EL en la primera unidad de acceso. La imagen BL puede estar asociada con un indicador. El procesador está configurado para determinar un valor del indicador asociado con la imagen BL, y realizar, con base en el valor del indicador, uno de los siguientes puntos: (1) eliminar una o más imágenes EL en un búfer de imagen decodificada (DPB) sin dar salida a dichas una o más imágenes EL antes de que la imagen EL se codifique, o (2) abstenerse de eliminar dichas una o más imágenes EL en el DPB sin dar salida a dichas una o más imágenes EL. El procesador puede codificar o decodificar la información de video.
