A system for use in an improved television set, audio stereo system, computing system, or other system capable of receiving, storing, transmitting, or processing an audio or visual signal, the system comprising:
a remote database;
means for receiving an initial audio or visual signal to which an additional digital information associated with the initial signal has been added, the additional information containing, in whole or in part, a first number which is uniquely assigned to the individual initial signal or copies thereof, wherein the first number represents an address to a location in the remote database wherein a pre-stored set of information associated with the initial signal is contained, and
means coupled to the system containing a processor responsive to basic operating instructions for enabling the reading of the additional information and enabling the real-time retrieving from the remote database of a subset of the pre-stored information via a communications link with the remote site; wherein the pre-stored set of information comprises a menu of options or commands. |
