Abstract
A music delivery arrangement permitting a subscriber to select from among a plurality of available music selections, particular selections that he wishes to hear at any time. The plurality of music selections are "played" at a central "jukebox" facility. They are frequency multiplexed onto one or more communication channels that are typically used to carry video information, such as cable television channel. The video channel information is distributed to individual subscribers either via unused channels of a cable television system, by direct broadcast at commercial television frequencies, by direct satellite transmission to a subscriber, or by some other means. The subscriber uses a converter box to demultiplex and thereby select a desired musical selection for demodulation. Demodulation can take place in the subscriber's FM broadcast receiver or in some other apparatus. Music selections are selected in a similar fashion to the manner in which particular channels of a cable television system are selected for video viewing. The music on the sub-channels is continuously played in such a way than any specific selection can be chosen at any time.
