Abstract

Un método de la invencion provee varios modos de reproduccion a través de seleccion controlada de ubicaciones de respuesta. Se puede facilitar la seleccion dentro de una corriente de video o entre corrientes de video separadas derivadas para velocidades de reproduccion trucada seleccionadas. El método permite que las selecciones sean descodificadas y presentadas independientemente de selecciones de corriente previamente de video. El método comprende los pasos de: identificar (paso 200) un grupo de señales digitalmente codificadas (NP, TP1, -TP1, TP2, -TP2) en un medio de memoria (110) para cada uno de una pluralidad de programas de video (P1, P2, Pn) para la produccion de cada uno de dicha pluralidad de programas (P1, P2, Pn) a una pluralidad de velocidades de reproduccion; enlazar cada una de las señales codificadas en cada uno de los grupos entre sí en los puntos de salto predeterminados (120); reproducir (275) una de las señales codificadas en respuesta a la seleccion de un programa y una velocidad de reproduccion; saltar (pasos 500/600) a las diferentes señales codificadas para la reproduccion de acuerdo con los puntos de salto predeterminados (120), en respuesta a selecciones subsecuentes de diferentes velocidades de reproduccion; y descodificar (510) las señales reproducidas para la presentacion (1000) del programa seleccionado a las velocidades de reproduccion seleccionadas.
