MUSIC DELIVERY SYSTEM |
摘要 |
<p>MUSIC DELIVERY SYSTEM 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. They are frequency multiplexed onto one or more communication channels 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.</p> |
