An interactive video system transmits a composite digital information signal consisting of a winnowed generic information signal and a local information signal manipulated to produce an output signal including both data code and object code. This output signal is formatted and transmitted via modulator cards at the system head end to decoders located at the individual users' television sets. Each card uses a dynamic gate array having a configuration sequence determined by a resident configuration EPROM which can be changed in the field. Data is fed to the configured array under the control of a control data EPROM also resident in the modulator card. A transmission modulator in the modulator card receives the data from the dynamic gate array for transmission via any selected medium to the user's location.

Systems and methods for continually updating and retrieving interactive video information

An interactive video guide system is provided in which nationally generic guide data, local guide data, and interactive video guide object code are transmitted to set-top decoder units located in customers' homes. Initially, nationally generic data or program information from a variety of sources is gathered together via modem at a central processing unit, and then manipulated, parsed and formatted into a national database compatible for use by a head end computer. This information is typically collected and updated on a daily basis. The manipulated nationally generic data is then transferred via modem to a transmitter for uplink to a selected telecommunications satellite. The satellite signal is then received by one or more local satellite CATV head end receivers which then forward a video base band signal carrying the nationally generic data to associated local head end computers. At the local head end computer, the nationally generic data is again manipulated, winnowed, parsed and processed to suit the requirements of the particular local market. Local guide data and interactive video guide object code may then be added to the nationally generic data and then the combined data and object code is transmitted over the CATV system to one or more decoder units in the consumers' homes.

System and method for communicating data and objective code for an

A method of transmitting data for video display in which a composite digital information signal is manipulated to produce an output signal including data code and object code, separately storing the data code and control data, processing the stored data in a dynamic gate array in response to the stored control data to provide a formatted signal that is transmitted to a receiver where the transmitted signal is decoded and passed to a video display in response to satisfaction of one or more predetermined conditions.
