: ATSC Tuners In HDTVs (see Samsung Poll)
2009-08-12, 01:42 PM
I receive about 30 TV channels (OTA) I use the in-built ATSC tuner on my TV.
My problem is the EPG which only displays the current programme. I cannot scroll thru to see future programmes.The Canadian channels do not provide details of their programmes, but the U.S. channels do though.
I have a 42" Samsung Plasma TV. How do I get say 3 or up to a 7day EPG for the channels I receive. Do I have to download a firmware?

I don't think you can,I have the same tv and only get info on whats playing. My other tv has the bell 9200 and gets no info whats so ever.Does anyone one which tv's come with EPG on them?

New to the forum!! Most of the stuff you publish is over my head but my issue is pretty easy to explain. My flatscreen is set for TV main-source and I selected Antenna instead of Cable. I am attempting to get my channels 58.1, 22.1 and 32.1 but my TV does not seem to tune into these at all. A friend of mine has a Samsung flat-screen and it even shows signal strength.I got an auto-scan feature but it will not pick them up. Is it true that some Flatscreens do not have the ability to pick up these OTA HD signals?? All that work with a great antenna sitting on my roof and now this. Any advise???;)

You'll have to check if your TV model has an integrated ATSC (DTV) tuner. There are a few models only have NTSC (analog) tuners built-in.

Since I read your reply I have since then researched the FCC regulations: * By July 1, 2005 all televisions with screen sizes over 36 inches (91 cm) must include a built-in ATSC DTV tuner.
By March 1, 2006 all televisions with screen sizes over 25 inches (64 cm) must include a built-in ATSC DTV tuner.
I am pretty sure that my Seanix 32" unit was purchased somewhere in Spring 2005 so i have a suspicion that even with a detailed look at my menu, that I do not have the ATSC tuner.
Now what? Any chance I can interface a ATSC tuner between the antenna and the flatscreen? Are there any cheap alternatives, especially as most of us are hobbyist of some kind, building our own contreptions?
Any suggestions without having me purchase a new flatscreen would be great!
Goodnight. Excited to read some encouraging replies tomorrow.

seymour59, did you buy your Seanix TV in the U.S.? I thought it was a Canadian brand. The FCC is in the U.S., not Canada, so if it is a Canadian brand of TV those rules do not apply.
For your ATSC options I suggest reading the OTA FAQ to understand the basics of what to look for. You have plenty of options. :)

Indeed, Stampeder: I was wandering the aisles of a big-box store the other day and noticed a handful of budget brand 32-inch (and smaller) televisions that didn't have an integrated ATSC tuner.

CFCN (Calgary CTV), is in the process of getting their PSIP data generated correctly, but even now my Sammy has issues with Virtual Channel, Station time/date and other similar data. All my other ATSC tuners (mostly computer-cards) and ATSC-TV's at friends seems to work ok with the current set of data...
Shame that Samsung somehow is a bit too sensitive on PSIP...

Anyone know what is the significance of "channel strength" and "signal strength" in the parameters of a Sharp Acquos TV? WTFM says you can select one or the other. It does not explain why.
I found the actual answer to this question when reading up on some info on the HDHR:
Signal Strength (ss)
- raw power level as measured by the receiver
Signal Quality (snq)
- how clearly defined the digital data is
Based on that, I would assume your "channel strength" is the signal strength defined above, while "signal strength" is the quality defined above.
2009-09-03, 02:58 PM
Yep, I think that cements it: one is the raw signal strength, the other is the BER.

Try putting Bit Error Rate into a manual and explain that in a few simple words.... :)

I have a channel master converter box on my JVC tube type TV. This converter lets you do a channel scan and then move the location of the antenna with the rotor and then do an add channel scan. I can't seem to be able to find a LCD flat panel TV which will let me do the same kind of scan. I can't do a rescan each time I move the antenna. I am trying to get stations from Ottawa-Kingston-Watertown and Syracuse.

Most will allow manual adds (i.e. just punch in the physical channel and if it finds something, it will add)
and others also have range scans (my viewsonic does, for example) that you can set a range you want and it will scan for new channels.
To get that, though, I have to go to the extended menus of the viewsonic (not mentioned in the manual or anything)

Thanks for the reply. The sharp aquos model LC-42d85U can't get it to do that. How do you get into the extended menu? Realy want to use this expensive TV without a converter box as it is another remote to confuse the wife.

The menu often has different functions between TV's..
in the case of viewsonic, it gave extra functions for calibration, channel scanning, etc.
In the case of samsung, it just gives service info and values and such (no user useful options aside from documenting the defaults if you're making changes)
I'm not sure about your TV specifically, but googling around should help you find it somewhere.
Usually "service menu" or "extended menu" are what you're looking for

57 you are correct. I need a TV make and model which will let me scan Toronto but then let me move the rotor to say Rochester and do an ADD channel. Because if I were to do a SCAN of Rochester it will drop the previous channel list from Toronto. Thanks fiero1988gt

Fiero, if you check out this link it explains a work around for the Panasonic Vierra plasma to do what you are asking.

For sharp LCD's enter the physical channel. For example CBC Toronto is on UHF 20, so if it wasn't in your original scan, enter 20.1. If it finds it, it will remap to 5.1 and be saved in your channel list. I don't have the LC42D85U but mine is only 9 months old, so I'm sure it works the same way on yours. To tune your antenna, go to Menu-setup-antenna setup digital and select channel strength. Under channel number enter physical channel. If you get signal strength>35%, you should be able to add. The only time you will have a problem is if a channel is already remapped to the physical channel. Ex. ION is physical channel 23 and CW Buffalo is virtual 23.1. When you enter 23.1 on the tuner it will go to CW and not add ION. To avoid this, you may need to plan which ones you add and in what order.

What happens if you enter 23.0? Shouldn't this tell the TV to look at physical channel 23?

If you enter 23.0, goes to analog 23 and snow.
