Well, the wires in the left hand picture look like they lead TO a device, like a DVD player (as has been suggested), or may a signal amplifier, or (fill in blank here).
Have you tried tugging on it, looking around the corner, even plugging it in to see if anything close by lights up?
The right hand pictures shows two leads, one of which I cannot see any connectors due to the angle you shot the picture. The other lead appears to be a stereo audio jack, but this is only a guess, as I have never seen that exact type of connector before.
Again, you need to go on a hunt, and if just looking and tugging doesn't do anything, and you can't contact the PO, perhaps you will have to remove a wall panel or two...
