Abstract

A system for remotely displaying screen data on televisions or the like transmits screen data over a plurality of commercial radio band carrier transmitters. A plurality of devices are provided, each being for use with a corresponding television in a home. Each device includes a band receiver and a decoder for receiving and decoding screen data. A display signal is then generated for viewing on the television or the like. Each device can include means for receiving responses from a user, for example responses to a program viewed. The device can also include a storage for storing both screen data and response data. This enables response data to be transmitted at a later time, and it can be collected by polling from a central computer. Similarly, screen data can be received and stored, for later viewing.
