| (54) | Music delivery system |
| (57) © A music delivery system permitting a subscriber to select from among a plurality
of available music selections, particular selections that the subscriber wishes to
hear at any time. The plurality of music selections are "played" at a central "jukebox"
facility (110). They are frequency multiplexed onto one or more communication channels
(114) that are typically used to carry video information, such as a 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. A subscriber uses a converter box to demultiplex and thereby select a
desired musical selection for demodulation. Demodulation can take place in the subscriber's
television 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. Each music selection is on an audio sub-channel of a video
channel. The music on the sub-channels is continuously played in such a way that any
specific selection can be chosen at any time. |
