CD-i member Geoff Lucas shared with us an unknown CD-i player which is a licensed 220 model, branded by AEI and Prodisc. It looks like this type of player was specifically aimed to serve as a CD-BGM player only (CD-BGM was a compatible CD-i format, offering background music in professional settings for several hours on a single disc). Wolverine Bates helps us: "the CD-i platform was utter nirvana if you worked for a company that subscribed to Muzak or AEI Music on disc and you were an easy-listening junkie, as home CD-i was descended from a platform (CD-BGM) meant for just that. And it remained 100$ compatible with it. Usually 37800 Hz ADPCM (type "B") audio, mono or stereo. That was an advantage (although a very minor one) it had over the other CD-based video game platforms of the day."
Patrick Selten found more clarification (and translates it): "It is used to play DMX music disc. A music service for ,what i think, companies for background music. DMX is offered as an on-premise business music service via DMX-Disc(R). The DMX-Disc service offers flexibility in situations where rooftop satellite dish installations are not possible, or where another building might lock the signal path from DMX Inc.'s satellite, through the use of on-premise equipment and custom DMX programmed CDs. DMX-Disc uses a compact disc interactive ("CD-I") player and a custom programmed library of CDs. These CDs are manufactured especially by DMX Inc. using a compression scheme which allows for over four hours of pre-recorded music to be played from one CD. Through the distribution and rotation of library CDs, a DMX-Disc customer is ensured of always having a fresh DMX playlist, mirroring the playlist from the DBS satellite feed."
