iPhone / iPad App "Watch On TV" Feature

I am interested in using the iPhone / iPad TIVO App to receive a TIVO stream at a remote location (away from the location where the TIVO Roamio unit is located) and then project / view the stream on a TV that is connected to the iPhone / iPad by an audio/video cable - Does the TIVO app support audio/video out ?? Some Apps do and some don't - What TV's does the iPhone / iPad App "Watch On TV" feature allow the user to use - Specifically, does the "Watch On TV" feature allow the user to view the stream on a TV that is connected to the mobile device by an audio/video cable or only to a TV that is hooked up to the local home TV network where the TIVO Roamio unit is located - Thank you in advance for your response - Howard
