Title: Broadcasting system linked with advertisement information
Inventor: SHIMOJI TATSUYA
IPC: H04N21/266
Filed: 2000-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a broadcasting system capable of effective advertising. SOLUTION: Contents are broadcasted from a transmitter 6, while being scrambled. Therefore, on the side of a receiver 2, these contents can not be viewed without a key for canceling scrambling, The receiver 2 accesses an advertisement server on the Internet or the like and requests advertisement information. The advertisement server 4 transmits the advertisement information to the receiver and transmits information showing the transmission of the advertisement information to the receiver 2 (advertisement acquisition information), to the transmitter 6. The transmitter 6 receives the advertisement acquisition information, specifies the user, to which the advertisement information is transmitted, on the basis of user information and transmits the key for canceling scrambling by broadcasting to the receiver of the relevant user as a destination. The receiver 2, which acquires the advertisement information, acquires the scramble key addressed to the receiver itself, cancels scrambling of the contents and is able to view the contents. Thus, the contents can be watched, in exchange for viewing of the advertisement information.
