How to control cable box in different room from TV -IR Blaster or other?

[Attic]

I'm trying to plan out some hardware and logical control for a home remodel.

I've got two rooms in this problem.

Room 1 is where all my Home Theatre equipment will be along with a TV.

Room 2 is where a second TV will go. I'd like to avoid having anything other than a Audio/Video cable to the TV in Room 2. ie) no cable box physically at this location.

Items i'm looking at is having a CAT6 run from Room 1 to Room 2 and having a cable box in Room 1 that will be dedicated to Room 2. Using a HDBaseT adapters to run the AV from that cable box to the TV in Room 2 over CAT6. Distance is 50-75ft.
-How would Room 2 control it's dedicated cable box physically at Room 1?

Is there something easier, or better for me here or something else I should have a gander at for having basically remote TV's able to grab AV from a central location? My main concern is remote control ability at Remote TV location. ie) I don't want TV in room 2 to be changing channels/settings for Room 1.

If you are only running 1 wire to the TV, I would highly recommend you get a HDMI matrix switch with at least 2 outputs (one for each TV) as well and put that in the closet with your other equipment. This way you can also have both TV's watch the same feed, share a blu-ray player, HTPC, AppleTV, etc., with both TV's, and or any combination there-in. Get as many input ports as you can afford on the matrix switch and connect most of your HDMI devices to that switch (you may want a 3 or 4 output switch if you have a HDMI receiver/pre-processor in the one room but they start getting pretty expensive for the added functionality you are adding).

You can use something like a IR repeater. Obviously hard-wired is typically the most reliable, but you can also go with something like a RF capable remote control (older Harmony 990/1000, RTI T3x, or similar universal remotes). A decent universal remote or two would be a good idea. Obviously some of the more expensive ones have features that would make it easier to deal with multiple remotes controling the same equipment (i.e. some of the more advanced ones will interact with a local computer or base station that keeps track of all the states of all the equipment but again, this is more of a convenience thing that you can mostly deal with standard help macros seen on most remotes).

To avoid things like controlling both boxes at once, most RF systems have an IR emitter that is on the end of a wire that can be taped across the front of the device you want it to control.
