View Full Version : Cable analog, off-air digital
AntAltMike 05-20-08, 09:56 PM A campground where I maintain the television distribution system offers DirecTV analog programming on cable STD channels 2-46 and integrates that with broadcast HDTV programming on UHF channels, which start at 470 MHz.
Unfortunately, not all TVs can be set up to simultaneously tune cable STD analog but broadcast, 8VSB HDTV. The customer just bought a big Toshiba for his conference center that cannot be programmed to do so, whereas he had previously bought a big LG TV for his general store that can integrate the two.
Is there any list here or elsewhere for TVs that can integrate NTSC cable analog with broadcast TV digital without the user having to go into the set-up menu to change from one to the other? Or can we start one here?
Scooper 05-20-08, 10:29 PM What about just using the existing CECBs as your digital tuner on one of the A/V inputs ?
Or maybe on the Antenna (if the CECB supports passthrough when off).
AntAltMike 05-20-08, 10:58 PM There are lots of ways to do it, but I am only interested in compiling a list of tuners that integrate the two channel plans. People at retirement homes are too dumb to switch inputs, and people using TVs in common viewing areas that they do not own will never be able to do anything any more complicated than to scroll channels up and down.

I would be surprised if there is such a list. Actually, LG is the only one I have seen do that. Every other one I have dealt with has you going into the menu..
Now, if some of your clients ever heard you talking about them that way... ;)
Rammitinski 05-21-08, 01:45 AM The earlier Sony digital sets used to do that - they integrated all the ATSC, NTSC and QAM channels into one. Don't know if they still do.
I'd ask over in the flat panel forums - I'm sure they could answer it for you.
nybbler 05-21-08, 10:19 AM I can only provide negative info -- the Sharp Aquos series cannot. It can remember both channel plans but you have to switch inputs.

Same goes for the Samsung LCD TV I own. I bought it new in December, so I would assume that all of Samsung's current models would work the same way.

Add my Hitachi plasma to the list. The Samsung DTB-H260F STB I own has a button on the remote to change from CATV to OTA. Nevermind, it doesn't do analog.
Desert Hawk 05-21-08, 06:02 PM On almost all tvs you will have to go into the menu to switch between cable and air. On cable mode the digital tuner will only respond to QAM. On air mode the digital tuner will only respond to 8VSB.
If you can find one of the old DirecTV Zenith DTV1080 boxes, it integrates OTA analog, cable analog, OTA ATSC and DirecTV MPEG-2. Doesn't need to be subbed to work with the OTA and cable. Probably can pick them up for next to nothing, now. Though if switching inputs is a difficult task for your clients, messing with an STB would be even worse.
AntAltMike 06-06-08, 08:10 PM I found another one. It is a 13 or 14" crt TV sporting the brand name: "Truteck" and assigned a model number CR130TT8.
It has the exact same menu as I found on a 26" CRT TV earlier this year, that MIGHT have been branded Sharp, but I'm not sure of that.
The tricky part is, there are four set-up autoprogram choices and the second and fourth choices are worded exactly the same, but picking the third autoprogram scan choice gets you analog cable channels, and then rescanning using the second autoprogram choice scans digital off-air only.

I see that this Truteck TV is made by Funai, and further investigation reveals that Funai is a leading OEM manufacturer of low-end TVs marketed under such familiar names as Philips, Magnavox, Sylvania, Durabrand, Emerson and Insignia, so I'll be checking the set-up menus on those products on store shelves to see if they have the set-up menu choices I desire. I see that Funai has negotiated the exclusive use of the names Philips/Magnavox effective September 1 of 2008, but that of course doesn't definitively settle the issue of whether their future TV products will have the capability of integrating analog cable TV with broadcast digital TV.
I use an older Directv box (RCA DTC210) that can be used strictly for OTA, but it also integrates analog cable, OTA analog, OTA digital, and MPEG-2 satellite without requiring any tuner changing. For example, when I had it hooked up for OTA and cable reception, using the channel-up button would look something like this:
Channel 2 (OTA analog)
Channel 2 (Analog cable)
Channel 2.1 (OTA digital)
Channel 2.2 (OTA digital)
Channel 2.3 (OTA digital)
etc.
All the tuner switching is done internally without any effort required by the end user. They don't have as good an ATSC tuner as newer CECB's and such, but if you are in an area where you don't need the latest tuner to lock in reception, then they are a good choice for what you are looking for. You can also routinely find them on Ebay (and sometimes CL, if you live in a big city) for around $20-40.
If you find one that comes with the RCA programmable remote, you can set it up so that it controls the TV and RCA seamlessly to make it as easy as possible for people who don't want the hassle of separate remotes.
