发明名称 Method and apparatus for contemporaneous delivery of data
摘要 A method and system for the contemporaneous delivery of data from a first location to a user at a remote location utilizes standard broadcast facilities as the transmission medium. The data and an identifier uniquely associated with the data are encoded and transmitted along with a first standard broadcast signal. An enabling cue signal corresponding to the identifier is encoded and transmitted along with a second standard broadcast signal. The first broadcast signal is received and demodulated at the user location, the identifier is decoded and the encoded data is stored in a memory location uniquely associated with the identifier. The second standard broadcast signal is also received and demodulated at the user location and is decoded to provide the cue signal. The cue signal is compared with the received identifier and if the comparison is positive the stored encoded data is recalled from the memory, decoded and printed at the discretion of the user.
