converting my system need advise on distributing the video

I currently have an analog system throughout my house with 16 cameras. They are old 600tvl cameras and at the time seemed like a good idea, but I have put a few 3mp cameras at the office and the difference is night and day, so I want to switch.

My spouse enjoys the heck out of the cameras and so I used the rg6 video out from the dvr and split the video 6 ways with good results and now I can watch the cameras in any of those locations throughout the house.

Typically my wife will leave the security cameras on in the kitchen tv. or in the kids rooms if she is in there, now my house was wired for satellite tv so there was already rg6 run everywhere through the house, but the question is if I switch to all ip cameras and run some sort of blue iris system how can I get the video out of the computer and then distribute it to all of the tv's in the house.

I do have ethernet run to almost every tv, but runing a hdbaseT balun to 6 tv's will get mighty expensive.

would the dedicated dvr forum be a better place for this question?

of note I already have a blue iris system at my office and it works great, but I can only distribute the video to my iphone/ipad, not to different tv's. of course I don't have tv's all around my office like I do at home.

A bit pricey, but these work AWESOME:
