distributions. Therefore, you local (theater room in the basement let's say) will be an IR to the receiver in the basement closet. All other TV's could use a UHF band to communicate to your DSS.
HDMI: If you choose to go this route (all video and audio in one cord) then run them in a hub and spoke to all your locations. Check this website for longer runs with HDMI over fiber or cat6

Here is what I would do for each room in my "new" home. Run Cat6 drops to multiple locations to EVERY room. Run RG6 quad shield to EVERY room. Fiber, if you like do the same thing. In your master bedroom for example, you would want to run RG6, Cat6 and HDMI in a 2" tube from where your TV is to be mounted in the master bed room to that point. That tube will run to the central location in your house where all wires terminate for your closet.
Tubing gives you future pulls for whatever OR to add more to that specific location. You can run speakers wires in tubes (smaller dimensions) for future runs as well. Tubes make everything so much easier to run later on.
If I were you and you were going to put a TV in every room then I would mount TV on the wall.
TV on the wall: Between your 2x4, mount a 2x6 between and nail that 2x6 to those 2x4. That gives you a location where your TV will be mounted or screwed into the wall. Not hitting sheet rock, but a 2x6. Give yourself PLENTY of space since down the road you MIGHt want to upgrade your smaller TV to a larger size. Plan accordingly and you can have a wonderful viewing experience even with surround sound in that room.
