Abstract

Se proporciona un método de decodificación de un flujo de bits de video codificado implementado por un decodificador de video. El método incluye el decodificador video que recibe el flujo de datos video codificado, el flujo de datos de video codificado que contiene una bandera gradual de la actualización de la decodificación (GDR) que corresponde a una secuencia video codificada (CVS); determinar, mediante el decodificador video, si una trama de GDR está presente en el CVS basado en un valor de la bandera de GDR; iniciar, mediante el decodificador video, la decodificación del CVS en la trama de GDR cuando el valor de la bandera de GDR indica que la trama de GDR está presente; y generar, mediante el decodificador de video, una imagen según el CVS como decodificado. También se divulga un método correspondiente de codificación implementado por un codificador de video.
