Milwaukee HDTV Technical Issues / more channels, more often
Wednesday Jun 17, 2009, 03:38:52 PM
May be a dumb question, but I'm going to ask it anyway.....

How does one manually tune digital channels on a DTV?  IOW, how do I look for a channel that the scan on the TV has not picked up?

Let's say a 'new' channel comes on the air as Ch 8-1 on RF39.  Short of telling the TV to rescan, can I just manually enter '39' and have it pop up?  (obviously, I wouldn't enter 8-1 as that is a faux channel number.)  If so, how does the TV know which tuner to use, NTSC, ATSC, or QAM?

I know I can enter random channel numbers and if there are still analog broadcasts on those channels they show up, but what about digital signals.

Quote from: Jimboy;52183All "Full Power" analog stations are required to pull the plug on June 12th. The transition doesn't affect low power analog stations....yet.

Ah, OK. Thanks for setting me straight.

??  Sounds like the 'deadline' was never really a deadline after all.  After all these months of telling everyone that after the date analog TV goes away, some stations will still be allowed to broadcast analog?  I was under the impression that it was a *requirement* that all broadcasting in analog cease on June 12th.  Apparently not.

Quote from: LoadStar;52033Yes, they broadcast in 720p of 1080i, but the source material they are broadcasting is most definitely not that resolution - it's just upconverted before broadcasting.
OK,  but what gives it away?  To my eyes anyway, both WITI and WISN and others are crisp and sharp - just not 16:9.

How are you guys defining "HD" in this case?  WTMJ is at 1080i, 16:9, certainly HD.  WISN is 720p, looks like 4:3 with sidebars.  I thought 720p was still considered HD - or is it the 4:3 that is bugging people?

Milwaukee HDTV Technical Issues / TWC and HD-Box Resolution Tip!
Wednesday Apr 22, 2009, 11:14:53 AM
Not sure I understand the rational for doing this.  I can see it perhaps making channel changes faster, but....

You pay big bucks for a high end TV that has a state-of-the-art processor to crunch the numbers and make whatever input is applied fill the screen, and then you offload that function to the cheap STB?  

I would think for best picture you would want the STB to do as little messing with the signal as possible.

But then again, I'm still watching TV on a 36" SD CRT.

General (Non-HDTV) Milwaukee TV / Analog interference..?
Monday Apr 06, 2009, 04:46:09 PM
May be leaky cables, may be the set itself.  If you disconnect the cable and put a 75 ohm dummy load on the connector, do any of the channels show through?

You may be able to help the situation by adding a booster amp to the cable, perhaps 10 - 15 dB.  As long as you do not start overloading the TV set's input you should be OK.  You would need to have this amplification ahead of wherever the OTA signal is leaking in.  

Adding the amp got rid of moderate ghosting on Ch12 for me in Brookfield.

Milwaukee HDTV Programming / TMJ4 Going HD... like in hours?

Statewide, we have a primary for State Superintendent of Public Instruction.

That's insane.  These stations plan for months to be shutting down the analog on Feb 17, and then a week before they are told not only do they not have to do so but they *can't*?   What happened to limited government?

Looked blue and yellow, not the normal blue and red.  Blue/red glasses didn't do much, at least not with my eyes.

Quote from: ArgMeMatey;50492Programming based on the ATSC standard tells a digital TV tuner or DTV converter box "When the couch potato enters 4.1 on the remote, show him UHF channel 28" and so on.  

Please correct me if I'm wrong... but the virtual to real channel is not fixed.  Milwaukee 4.1 translates to 28, but Poduncks 4.1 may translate to 37.  So the ATSC tuner has to 'learn' the correlations via a scan before it can tune the proper channel based on a virtual channel command.

Milwaukee HDTV Technical Issues / TWC w/o STB
Friday Jan 16, 2009, 02:10:14 PM
It sounds like, at least for now, a set top box is the practical way to go.  Just strikes me as a waste that the TV has built in ATSC, NTSC, and QAM tuners, and you end up basically just using it as a monitor.  

That and those TWC remote controls I've seen strike me as awful.

Milwaukee HDTV Technical Issues / TWC w/o STB
Friday Jan 09, 2009, 02:53:10 PM
Thanks ArgMeMatey.  I do have Road Runner also.  So if I went out tonight and bought a replacement for that old analog set and did nothing with my cable subscription, I would be able to receive everything I am currently receiving via the built in NTSC tuner and the 'local' digital content via the the built in QAM tuner.  Right?

Thanks Will.  Tru2way sounds like what I had previously seen referred to as the next generation cablecard.  Yes, that would be what I would be looking for.  I was under the impression that TW Milwaukee did support the original cable cards, just not the 2-way versions.  

Anyone know of any 46-52 inch HDTVs that support the cablecard/tru2way option?

Milwaukee HDTV Technical Issues / TWC w/o STB
Friday Jan 09, 2009, 01:39:14 PM
Hello.  I'm new to the forum, trying to get up to speed on DTV/HDTV issues before taking the plunge into a new HDTV and programming.

I currently have TWC standard tier analog service.  The analog TV does all the channel selection and I do not have any type of set top box.  I receive all the channels in the lineup just fine that way.  I *like* not having a STB.  

I understand that TWC uses QAM on the cable for digital content.  All new HDTVs list QAM tuners as standard.  Using the TV's built in QAM tuner, will I be able to receive all the default stations that TW include in the 'Digital package'?  

I would guess that if I added any DTV/HDTV content beyond the basic, that those new signals would be scrambled QAM and I *would* need a STB to get those. Correct?

If I have to, a cable card would be preferable to me rather than a STB.  But I have not seen any HDTVs advertised to have the ability to take a cable card.  Are there any out there?

Thanks,
Derf
