The transmitter delivers a second set of digital data to the receiving device. In one embodiment of the present invention, the receiving device contain a timing device for automatically receiving the second set of digital data at predetermined times. In another embodiment, the transmitter transmits an alert signal indicating a transmission of the second set of digital data. The second set of digital data contains a first set of displayable data, a second set of displayable data, at least one non-displayable symbol, and at least one linking reference associated with the second set of displayable data.
