Abstract (en)
[origin: WO9010988A1] A system (1) for remotely displaying screen data on televisions (3) or the like transmits screen data over a plurality of commercial radio band carrier transmitters (5). A plurality of devices (13) are provided, each being for use with a corresponding television in a home. Each device includes a band receiver (33) and a decoder (35) 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 (20) for receiving responses from a user, for example responses to a program viewed. The device can also include a storage (51) 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 (25). Similarly, screen data can be received and stored, for later viewing.
