Abstract

Una grabadora de casetes de vídeo digital (210), del consumidor, puede grabar una señal de television por adelantado (09) teniendo un formato de señal similar a MPEG. La naturaleza predictiva del formato de señal similar MPEG requiere que se generen datos del marco I adicionales (51, 61, 71) y se graben junto con una corriente de datos de velocidad de reproduccion normal (09) para facilitar la velocidad no normal, o la difusion de reproduccion trucada. Las corrientes de datos del marco I adicionales (521, 531, 541) se generan específicamente para cada velocidad de reproduccion y se escriben dentro de bandas grabada para facilitar la reproduccion a velocidades predeterminadas. Se describen varios métodos de la invencion para la derivacion de corrientes de datos de reproduccion trucada de resolucion completa y resolucion reducida. Se describe la generacion de corriente de datos de reproduccion trucada de la invencion para grabar en tiempo real mediante el aparato del consumidor y generar corriente de datos de reproduccion normal y trucada de tiempo no real para usarlos con medios digitales pregrabados.
