Abstract

La presente invención se refiere a un controlador de banda de sistema de cable televisión que comprende un generador de datos para generar datos capaces de ser transmitidos a través de una trayectoria de transmisión, un transmisor para transmitir por lo menos un canal de televisión, un mezclador, un receptor superior de tipo en banda en una primera ubicación predeterminada para recibir por lo menos un canal de televisión y para recibir los datos transmitidos dentro de por lo menos un canal de televisión y un receptor superior de tipo fuera de banda en una segunda ubicación predeterminada para recibir por lo menos un canal de televisión y recibir los datos transmitidos al exterior de por lo menos un canal de televisión y mediante otro canal de transmisión transmitido por el sistema de cable, un aparato de control de datos generados caracterizado por contener un controlador conectado funcionablemente entre el generador de datos y el mezclador para recibir y analizar los datos recibidos por el generador de datos a fin de determinar si el dato va a ser transmitido al receptor superior de tipo en banda o receptor superior del tipo fuera de banda para controlar la trayectoria de transmisión a través de la cual se transmite el dato.The present invention relates to a television cable system band controller comprising a data generator for generating data capable of being transmitted through a transmission path, a transmitter for transmitting at least one television channel, a mixer , an upper band-type receiver at a first predetermined location to receive at least one television channel and to receive the data transmitted within at least one television channel and an upper out-of-band type receiver at a second location predetermined to receive at least one television channel and receive the data transmitted to the outside of at least one television channel and by means of another transmission channel transmitted by the cable system, a generated data control apparatus characterized by containing a controller operably connected between data generator and mixer to receive and analyze data received by the data generator in order to determine whether the data is to be transmitted to the upper band-type receiver or upper out-of-band type receiver to control the transmission path through which the data is transmitted.
