Note how the video resolution (480x234) and the screen size (7 inches)is the same as the specs of the embedded digeplayer. The top 2 players look like the one in the seat lower down in the ad about the embedded digeplayer (i.e. no buttons on the front).

Some of the other models could be based on the odyssey or kino platform as well. Who knows?
