Abstract (en)
[origin: WO9718675A1] A system for sending selected up-to-date information in a television signal from a sender (100) located at a network head-end for television station to a receiver (102) co-located with a television viewer. The television viewer subscribes to an information service by telephoning a customer service center (128) affiliated with the sender. The customer service center informs the sender of the subscription and the sender sends data packets of information individually targeted for the television viewer in the vertical blanking interval of the television signal. The television viewer's receiver accepts (114, 116) the data packets identified for it and on viewer command displays information included therein on the television screen (122). The data packets include information relating to news, sports results, financial market updates, television programming guides, and the like. Information is displayed to the viewer in a menu format, allowing for ease of use in controlling presentation of various types of information.
