摘要
A method of identifying a time-variable component (such as a song) of a broadcast signal, and thus identifying for example the tittle of the song or the performing artist of the song being broadcast. The required information is encoded on to the broadcast signal and is changed for example each time the song being transmitted is changed. The information is extracted from the received broadcast signal, and is then stored for later retrieval - for instance, a person hearing a song might press a storage button on a receiver which then stores the name of the song and the artist ready for recall subsequently by that person.
