Abstract
Se divulga un mecanismo de codificación de video. El mecanismo incluye recibir un flujo de bits que comprende una imagen de actualización de decodificación gradual (GDR), una imagen de punto de recuperación que sigue de la imagen GDR en orden de decodificación y una cabecera asociada con la imagen GDR. La cabecera incluye un valor de bit menos significativo (LSB) de recuento de orden de imagen (POC) codificado antes de un valor POC de recuperación. Un POC para la imagen GDR se determina con base en el valor POC LSB. El valor POC de recuperación se determina con base en el POC para la imagen GDR. El valor POC de recuperación indica un POC para la imagen de punto de recuperación. El flujo de bits se decodifica de acuerdo con GDR con base en la imagen GDR y la imagen de punto de recuperación.
