Abstract

Una grabadora de cinta de video digital que graba una señal de alta definnicion que tiene una estructura compatible con MPEG tal como una señla Grand Alliance propuesta. En el formato grabado un cuadro de television avanzada ocupa diez pistas grabadas. La reproduccion a velocidades diferentes de la velocidad grabada se denominan de "Representacion Trucada". La reproduccion en un modo de "Representacion Trucada" necesita una cabeza de reproduccion que atravieza una pluralidad de pistas grabadas. Sin embargo, ya que la señal de television avanzada está estructurada como grupos de imágenes que comprenden un cuadro codificado como intracuadro y una pluralidad de cuadros pronosticados, muchas de las pistas grabadas contienen datos que representan cuadros pronosticados. Por lo tanto una señal de television avanzada reproducida en "Representacion Trucada" puede representar una mezcla de segmentos de datos no relacionados. La operacion en "Representacion Trucada" puede facilitarse mediante la seleccion de velocidades de reproduccion y la localizacion de ubicaciones específicas dentro de cada pista a partir de las cuales pueden ser reproducidos los datos. Esas ubicaciones de cinta específicas son utilizadas durante la grabacion para colocar datos de imagen de television avanzada para la reproduccion durante la operacion de "Representacion Trucada". Los datos de imagen de Representacion Trucada". Los datos de imagen de "Representacion normal aunque no son utilizados. Las ubicaciones de pista específicas son seleccionadas para facilitar la operacion de "Representacion Trucada" a una pluralidad de velocidades en las direcciones de avance y retroceso. Ya que la señal de television avanzada comprende una pluralidad de cuadros pronosticados, la transicion de la "Representacion Trucada" a una reproduccion de velocidad normal requiere una funcion de control la cual es sensible, a la velocidad de reproduccion normal, de un cuadro codificado como intracuadro. Se describen varios métodos de transicion de imagen reproducida para seleccionar a y desde la reproduccion de "Representacion Trucada".
