1) The TV or another display device hooks directly to the “Juke Box,” which often takes the form of a set-top box, (though it can be a much larger unit, and could have a video screen built-into it.) Whatever network it's hooked up to, (the transmissions could come via satellite,) the Video Juke Box regularly receives, and often is automatically updated with, different music videos. The least played tracks are automatically deleted upon each transmission of new material.
(2) Small electronic devices like iPods that record and playback music. (Slang) TouchTunes Interactive Networks is an example.
Video Jukebox Network / The Box - There are some that like to call it the first interactive television network. https://en.wikipedia.org/wiki/WBXK
