We are a 69 bed facility. Each TV has it's own DTA so the cable channels are able to be controlled independently (Bed A can watch channel 32, and bed B can watch channel 109). Spectrum supplies a Universal Remote that is "paired" to the cable box, and works off of a code search to program the TV functions (TV on/off, and TV volume).
The issue is within the TV functions (TV on/off, and TV volume). Bed "A" turns on his/her TV and it will turn on/off bed "B's" TV. Bed "B" could turn the volume up on their TV, and it will do the same for bed "A" etc.
There are probably 80% of the rooms effected by this issue.
Sounds to me like a simple case of IR from the remote controlling 2 TVs at the same time. The only way to solve this is to either do as Buzz said and try and move TVs around...or get a universal remote that uses RF to communicate with a base station..that then sends IR commands to the TV and the cable box via IR emitter. This will allow you to control how far the IR can go...stopping the cross controlling of devices.
The only time we have an issue with person in bed "A" changing bed "B's" channel is if the remote accidentally gets "paired" to the other person's cable box.
Since the introduction of these individual DTA's for each TV, "changing the TV channel" no longer exists. The "channel" is only changed through the DTA, leaving the TV set to HDMI input and just receiving the signal. If one was to physically push the "channel button" on the TV itself, it would simply display either static or "no signal" until the input is returned to HDMI.
This is normal and nothing to be concerned about. It actually makes your problem easier to deal with IMO.
There are also varying makes and models of TV's in every room (little to no uniformity at all). Some rooms have two 24" LG TVs. Some may have a 19" Magnavox and a 32" Emerson. Another may have and 48" Zenith, and a 19" RCA. There doesn't seem to be any rhyme nor reason to this. I could understand if two like brands and/or models were having issue, but it's all varied.
