Abstract

Un método de la invencion provee varios modos de reproduccion a través de seleccion controlados 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 vídeo. 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 (10) para cada uno de una pluralidad de programas de video (P1, P2, P + n) para la reproduccion de cada uno de dicha pluralidad de programas a una pluralidad de velocidades de reproduccion; reproducir una de las señales codificadas (NP, TP1, -TP1, TP2, -TP2) de la memoria (10) que responde a una seleccion de programa y a una velocidad de reproduccion; calcular una direccion (paso 375) para iniciar la reproduccion de una señal diferente de las señales codificadas (NP, TP1, -TP1, TP2, -TP2) que responde a una nueva velocidad de reproduccion; reproducir (paso 600) la señal diferente de las señales codificadas (NP, TP1, -TP1, TP2, -TP2) a partir de la direccion en la memoria (10); y, descodificar las señales reproducidas para presentar el programa seleccionado a la nueva velocidad de reproduccion seleccionada.
