Abstract

A system for providing interactive services in a subscription television system comprises a system network controller for controlling the interactive services having controller memory for storing subscriber terminal identification data, transaction identification data and transaction return data, and a processor, coupled to the controller memory, for generating a transaction having interactive transaction data and transaction identification data. The processor also correlates received transaction return data with at least said transaction identification data and calculates summary data therefrom. A first transmitter transmits the transaction to terminal apparatus, and a first receiver receives transaction return data from terminal apparatus. A video signal source transmits a video signal to the terminal apparatus. The terminal apparatus, which is coupled to the first transmitter and the video signal source, receives the video signal and the transaction identification data. The terminal apparatus particularly comprises data input circuitry for receiving transaction return data, terminal memory for storing the transaction return data associated with the transaction identification data, a terminal controller, coupled to the data input circuitry and the memory, and a data return transmitter for returning the associated transaction return data and the transaction identification data to the first receiver of the system network controller. The terminal controller determines completion of entry of transaction return data for a particularly identified transaction and, immediately after data entry completion, initiates return by the data return transmitter.
