ATSC Tuners in Satellite or Cable Receivers - Page 33 - Canadian TV, Computing and Home Theatre Forums

Hi everyone:

Haven't been here in years. It's nice to be back at such a friendly site.

Just wanted to ask a quick question about testing. We happen to have Rogers here, but we've been thinking about switching to OTA.

We have a couple of the Rogers (Cisco-labelled) Digital-to-analog converters. One has been authorized, the other, not yet-it's still in the box.

If I wanted to try out an OTA antenna, will the Rogers DAC work for basic tests, or is it not compatible/authorized for use with OTA signals?

If it does work, are there any kinds of limitations (I assume it would then work with ANY TV, not just the TV on which it was authorized)?

Thanks

Brainer

They are QAM, not ATSC tuners. They will not work. Your TV may have an internal ATSC tuner...

If you wish to discuss OTA, please start by reading the following "Welcome" post and follow the instructions there before posting in the OTA forum.

Sorry about that. Just noticed this now.

I would like to know if it is possible to use a 6100 as an HDTV OTA tuner only. It allows me to scan for digital channels in the setup menu, but will only scan fo 82W and 91W transponders after I put it into operaional mode. I have switched to Shaw Direct and do not have the dish for Bell set up anymore and the receiver keeps searching. I realise that this receiver would have had to be replaced due to the forthcoming MPEG-4 conversion as I received a letter from Bell advising me to trade it in. But it seems to me that I could still use it as an OTA tuner. Is there a way to keep it from searching for the satellites and just have it function as an HDTV tuner?

^^^From what I have read, Satellite receivers are programmed to not work OTA unless you subscribe to a satellite service.

You don't need a sub, just a signal on 91.
Then it will work as a OTA tuner.

DaveFormula · 2012-08-03, 09:43 AM

OK... But, since I don't have it hooked up to a dish I guess that it won't work. I no longer have a dish for Bell. I use Shaw Direct now.
Thanks for your response.

I'm not sure if this is the right thread for my question, but here goes. We have an Antennas Direct DB4e. We are wondering how to get the surround sound. We have an HD TV and a sound bar. The antenna is connected with a coax cable. How do you convert the coax to HDMI??

classicsat · 2012-08-07, 09:22 AM

If you mean from the antenna coax, you get an ATSC tuner with HDMI. That essentially replaces the tuner in your TV.

For digital audio coax (different than RF coax), you don't (that I know of), but connect that to the digital coax in on your surround processor. If it has optical in only, you can gt a coax to optical converter.

Last, would be to get a surround system that has the digital input from your TV.

roger1818 · 2012-08-07, 11:22 AM

cableredneck, since you are posting in the "ATSC Tuners in Satellite or Cable Receivers" I am assuming you are using a satellite receiver as your ATSC tuner. What model of box are you using? That will help us determine if it has a digital audio out.

cableredneck · 2012-08-07, 12:03 PM

The antenna coax cable is currently connected into the DVD input of our surround sound bar. This is because we have a satellite service as well, and all the other inputs are taken up by those connections. This is why we are wondering how to get the surround sound from the antenna. The antenna is connected into the antenna/cable input in our TV. There are two HDMI inputs that are free. The problem is the coax cable can't be input into the HDMI inputs. Is there a small device that will covert the coax to HDMI?? There is also a blu-ray player in our system that is connected to the sound bar.

Dave Loudin · 2012-08-07, 12:46 PM

To clear things up, the sourround sound is decoded by whatever device is your tuner for digital OTA. Remember that the received digital TV signal is just a stream of ones and zeros. The tuner is reponsible for separating the video, audio, and data portions of that stream. I know I'm a bit confused with how you describe where the coax is connected (both the sound bar and the TV.)

So, whatever device you use to pick OTA channels should be the tuner. At that device, you need either fiber or coax digital audio out or HDMI out that will be routed to the soundbar for final processing.

holl_ands · 2012-08-07, 03:20 PM

Please provide manufacturer name and model numbers for Sound Bar, HDTV and other components.

The antenna downlead coax cable connects to OTA TV input on HDTV, which decodes the video and
digital surround audio data streams. Many/most HDTV have a Digital Audio OUTPUT connector, usually
optical but might be SPDIF Coax. However, since the HDTV requires processing of the surround
to derive STEREO (L, R) for it's internal speakers, it may or may not supply STEREO instead of Dolby
Digital 5.1 SURROUND on its' Digital Audio OUTPUT connector, which would be connected to Sound Bar.

I've hooked up a CM 4228 antenna to the OTA input on my Bell 9242 Sat receiver. Does the receiver dumb down the HD signal? It appears to be lower quality than directly connecting the antenna to the TV (LG 42LS5700). I am using TV2 co-ax output. Would using the component video output give me HD? The TV only has one co-ax input so I may have to use an A/B switch.

Yep. Coax output is standard def only.

I don't know the capabilities of your receiver, but either a HDMI or component (not composite) interface offers the opportunity for a higher definition display. You'll have to find out if your receiver is even capable of HD output of a tuner signal.
