Abstract
Las páginas de datos (305, 310, 315, 320, 325, 330, 335) de una guía de programas interactiva (IPG) para television se transmiten de cuerdo a una funcion de entremezclado que permite a los diferentes receptores de television recuperar segmentos particulares de las páginas de datos en base al día y hora de listados de programas que un observador desea ver. Una página de datos, que corresponde a una imagen de pantalla completa, se divide en segmentos (200) y se recupera por los receptores a través del tiempo. Los segmentos se entremezclan para proporcionar una separacion optima en la corriente de datos. La separacion optima corresponde al tamaño de la memoria intermedia de entrada del receptor y a la velocidad de procesamiento. las páginas pueden instalarse de manera secuencial (figura 3), o con las páginas numeradas pares separadas de las páginas numeradas impares (figura 5). Las páginas se dividen en un numero de subconjuntos (640, 680), y, dentro de las páginas de cada subconjunto, los segmentos se entremezclan de acuerdo a una funcion de entremezclado perfecta de tal manera que los pares de segmentos adyacentes respectivos se instalan en un orden que maximiza una mínima de sus distancias entre segmentos después del entremezclado. La distancia mínima entre segmentos de todos los subconjuntos se utiliza para determinar un tiempo de arribo entre segmentos característico, que debe ser lo suficientemente grande para corresponder a la capacidad de procesamiento del receptor. El tamaño de memoria intermedia de entrada requerido y la velocidad de procesamiento de los receptores se reduce, y todavía la velocidad de adquisicion de página de datos se incrementa para todos los observadores.
