While watching a "recorded program" from my playlist via BBC iplayer through my sky puck the broadcast was interupted by a text message from an unrecognised sender that kicked out iplayer and put us back to the home screen with the message overlaid. Because I immediatley pressed the home button to get back to my program I don't know who the text message was from or what it was about. I had to then go back to my playlist to get back into the program. This has now happened twice, what is the likely cause?
