Abstract

La presente invencion se refiere a un metodo (200) y un sistema (100) para producir una reproduccion en modo de truco de un segmento de video que contiene una pluralidad de imagenes de prediccion. La invencion incluye los pasos de: (a) decodificar (212) una porcion de una imagen de prediccion de la pluralidad de imagenes de prediccion; y (b) actualizar (214) una porcion de informacion almacenada en una memoria con la porcion de la imagen de prediccion. En un arreglo, la invencion puede incluir ademas el paso de repetir los pasos (a) y (b) durante la reproduccion en modo de truco de manera que una porcion de cada una de un numero predeterminado de imagenes de prediccion subsiguientes puede ser decodificada y puede ser usada para actualizar una porcion subsiguiente de la informacion almacenada en la memoria. Ademas, el segmento de video puede ser un segmento de video MPEG que no contiene ninguna imagen intra y cada una de la pluralidad de imagenes de prediccion puede contener macrobloques intra.
