Thanks guys. Still a little confused though. Since it only has 1 HDMI cable going out, does that mean that there is some place where all the TV HDMI cables come together? There are 3 TVs (bedroom, living room, outside), so it seems like they must join up somewhere if this sends a signal to all 3 at the same time.
If that is the case, why have a 4 output box that takes up so much space?
Also, what 2 HDMI sources would be going into it right now? The only things I can think of are the cable and the antenna.
