Atrium Medical Center - Middletown, OH (about 30 miles North of Cincinnati, it's a new facility opened Dec 2007, their old facility used SD cable feed from TWC, and 20~25 inch'ish DV-CRT's )
They had Most Dayton+Cincinnati HD broadcast stations in HD, they are apparently using Off air pickup as digital/HD stations and SD multicast services not available in the area via cable or DBS LiL in area are present -- These are apparently being remodulated to VHF channels with PSIP stripped, in most cases being received using internal 8VSB or QAM demods(I couldn't tell which) on the sets ...
3 of the 4 Cincinnati/Dayton PBS HD digital affiliates(all run different HD schedules), and TBN digital as well as Dayton CW HD affiliate aren't present from what I saw, but the other 10 current Cincy/Dayton digital/HD broadcast stations are, including CW SD via Cincinnati CBS station which multicasts the SD CW channel, and including the Cincy MyTV HD affiliate and one Cincy PBS HD member station(unfortunetly currently the one that has the least PBS HD out of the 4 as they only have it when live PBS HD channel programming "coincides" with their analog's schedule. And, CBS, ABC, NBC, Fox HD affilates from both markets were also present ....
Although, in the patient rooms, only a SD 480i multicast "subchannel" is apparently available from the Dayton NBC digital affiliate .. I expect this is related for "some reason" to the following : this station has it's streams set up so the PID(packet identifiers) for the SD subchannel for MPEG2 "program number 3" has PMT PID at hex address 0x0030 (video ES PID 0x0031, primary audio ES PID 0x0034 as you would expect), but it remaps via PSIP to 2.2, whearas their HD service is MPEG2 "program number 4" with PID at 0x0040, but it remaps via PSIP to 2.1 ... Both of these HD+SD services("subchannels") are "tunable" on the waiting room sets I "channel surfed through", but only the SD subchannel (what most of us get OTA via PSIP on 2.2) is present from this station on the sets in the patient rooms ... (of course that's no biggie since the Cincinnati NBC HD affilite's HD is on the patient sets) ....
The cablenets they have are currently all SD, from D*, they're present on UHF, using the analog tuners in the sets ... For some reason, when I've been visiting a family member over the past week, a "Directv" banner was present on the ESPN2 channel(ESPN + ESPNC were fine), which was a bummer last saturday as Family member I was visisting wanted to watch the NASCAR Nationwide series race ...
Note that these services/channels are "labeled" in a channel banner that shows up on the sets as follows "CBS" ,Discovery channel"/etc/etc .... Channel 2~13, where the broadcast digital signals are (on the waiting room sets with minor channel numbers present as well, such as "5.1, 5.2" ... ) are shown on the channel banner/OSD info as "digital", channels 14~45 are shown in the channel banners as "analog" .....
All the sets are LG or Zenith LCD HDTV's (16x9 displays), all are wall mounted that I saw. all the patient rooms have 26" models, there are mostly 42" models in waiting rooms(may have seen a 50" or two as well), a couple of the latter I looked at were hooked up to LST-4100 "control boxes", also wall mounted.
the displays were "set" for 16x9 display, which worked fine for the 720p or 1080i broadcast sources, but with no pillarbars "added" for 4x3 material from the SD services this resulted in "stretched" SD(i.e. short fat people/etc) ... While one can adjust the display mode via a "menu" option on the set for proper AR to result from 4x3 sources(i.e. add in pillar boxes on the sides, or even "crop/zoom" mode for 16x9 letterboxed stuff "inside" a 4x3 signal), I noticed the sets reset back to 'full' or "16x9 mode" if power is cycled and there seemed to be no control of this from the patients' remotes, which means you see a lot of "stretched" SD except on sets which are not tuned to the 720p/1080i broadcast sources ...
Also noticed that while various SD multicast subchannels are "present" on the waiting room sets(and the dayton NBC HD affiliate's HD service("subchannel) as noted earlier) such as weatherPlus from the Cincinnati NBC HD affiliate, but not present/tunable on the sets in the patient rooms, If I recall correctly, except for the Cincinnati "CW" affilate which is a SD multicast on Cincinnati CBS HD affiliate's digital station. But, I didn't try to see if a "channel scan"/etc would fix this or if I could even access such a "scan option" from the "buttons" on the sets ...
Other than the display/AR formatting "issues" resulting in a lot of "short fat people" seen on screen for the 4x3 SD sources, I thought it was pretty cool they way they're doing it, and of course, keeping in mind the place has only been open for a couple of months .....
While I did notice a lot of sets tuned to 4x3 SD sources w/o anyone reaching up to press a couple of buttons on the set to "fix it" (well except for me

, I also noticed a lot of "HD watching" of the local broadcast affiliates, including The Cincinnati ABC affiliate which has HD local news, and the CBS Dayton affiliate which has Widescreen SD local news, which in this case turns out looking remarkably good(especially the studio shots) broadcast as upconverted to 1080i ....
More than anyone wanted to know probably, but again, except for the "stretched SD" all in all I thought it was pretty cool how they've made their "DTV transistion" ...
