Abstract

Un dispositivo de computación puede obtener, a partir de un primer flujo de bits que incluye una representación codificada de los datos de video, un mensaje de Información de Mejora Complementaria (SEI) que incluye una indicación de un modo de extracción que se utilizó para producir el primer flujo de bits. Si el modo de extracción es el primer modo de extracción, el primer flujo de bits incluye una o más imágenes codificadas que no son necesarias para una correcta decodificación del conjunto de capas de salida objetivo. Si el modo de extracción es el segundo modo de extracción, el primer flujo de bits no incluye dichas una o más imágenes codificadas no necesarias para la correcta decodificación del conjunto de capas de salida objetivo.
