Given two data feeds, find out if they capture the same information
The problem of finding the relationship between two scenes shot from two different angles is known as the correspondence problem and there is a lot of literature on how to approach it; I suggest you start by reviewing the research literature on methods for solving this.  In particular, I'd suggest that if you can consistently find a correspondence between the two images, you might conclude that they are from the same feed; and if you can't, you might conclude that they aren't.
