A METHOD FOR INCREASING THE FUNCTIONALITY OF A MEDIA PLAYER/RECORDER DEVICE OR AN APPLICATION PROGRAM

摘要

A method for utilizing a title signal contained in data through a comparison of the title signal to a player signal stored in a player device is provided. The method includes the steps of: providing data (102) having the title signal; detecting (104, 206), at the player device, the title signal in the data; comparing (110, 214) the title signal to the player signal stored at the player device; and performing (114) an action based upon the comparison. The action is performed if the title signal matches (112) the player signal, and the action is to inform the device user of the match and the winning of a prize. In another preferred implementation, the title signal is a subsignal of a watermark signal encoded in the digital data, in which case the method further comprises the steps of: extracting the watermark signal from the digital data; and decoding the subsignal.
