Wilmington, NC - HDTV - Page 52

post #1531 of 2194
For those interested, here's the e-mail reply I received from Wayne Estabrooks (Engineering Specialist) at UNC-TV concerning their new DT subchannel setup beginning on Sept. 25th:

Quote:


Mr. *****,

If you are referring to over-the-air (OTA) digital reception with an
antenna, we are expecting to go to full time HD on the 25th of
September. This will result in 2 less subchannels overall.
The subchannel lineup for OTA will only have three subchannels. They
will be UNC-TV -1, UNC-KD -2 and UNC-NC -3.

Cable carriage will be mostly unchanged.

The UNC-TV -1 subchannel will be primarily HD 24/7 and the KD and NC
channels will be SD. The UNC-TV -1 channel will be in the HD format
full time but there will be some SD programs or widescreen SD programs
in the schedule. I hope this answers your questions but if not, please
feel free to e-mail me at westabrooks(*at*)unctv(*dot*)org or call me. Please also let us know where you are located and which UNC-TV station(s) you receive.

From Dan Ullmer:



Our Dolby encoder failed the morning of September 8th creating major audio issues when the center channel was no longer mapping to left/right almost completely eliminating the Today Show anchor audio. It was a big problem and we had to bypass 5.1 encoding for now until we can get the issue resolved.

Wayne's still kicking around after retirement...

I hope they devote a lot of bandwidth to the HD channel...

Anyone notice video quality problems again with WILM HD? It seems awfully green lately...

How do their over-the-air vs cable/sat picture qualities compare?

--- CHAS

Can't necessarily answer that question, but a few pages back (in this forum), I provided some data on cable vs. OTA data rates, using TSreader, that one of our member analyzed a bit... sorry, don't have that post number handy...

I think it's pretty comparable though... (page 44, I looked it up...)

What's a "stat mux"?

The short definition is that statistical multiplexing is allocating more bits the more they're needed. So if an HD image is relatively static, it can take some bits from that and give it to the SD feed. Then when there's motion or other things in the HD that need the bits, it takes them back from the SD feed so the HD's picture quality doesn't degrade as badly.

I remember when I first saw a demo of this in Japan at Mitsubisihi. It was impressive until the soccer match really started to move and then the pixealtion was fierce!

i am hoping i can get some good advice from you guys here. i live off 17th st. extension in an apartment and was hoping i could get a recommendation on a good antenna to get to hook up to my converter box. I currently have a really old pair of rabbit ears and a really old bow tie (both are twin lead) connected to a dual adapter which is connected to my converter box. I can pick up wway, wect, wsfx, wunj, and tbn with excellent quality, as long as both the uhf and vhf antenna are in (I tried uhf only and the signal strength dropped tremendously. I was hoping to get wilm and the ion/my network station out of jacksonville. Any recommendations for an indoor antenna? Also, would it be possible to get any distant markets with an indoor antenna? Any help would be greatly appreciated.

I have been impressed with the Philips omni flat panel array from Walmart. It's about 35 bucks with a built in preamp. I live in the Holden Beach area and can get the CHS stations with the antenna in my 2nd story attic with 20 feet of RG 59. I would go with RG6. The 59 comes with the antenna.

On occasion we have picked up Jacksonville Stations with pre-amped rabbit ears from our studios on Front Street.

What was WWAY doing to the tower with the radar dome this past week? Saw a couple of guys up at the top, I think it was Thurs...?

Cool! I hope they are planning on using that radar again. I enjoyed being able to watch a live radar that would actually be updating with every sweep. Right now they are using the Noaa radar at all stations I can get. It is over 6 minutes old at times.

We have a MyNetwork TV station, and a PBS licensed to Jacksonville, and the nearest major network is ABC from New Bern. If you don't get the ABC down there now, you should when they flash cut to channel 12 for digital. They run an independent station with a lot of different shows called ENC TV too.

Oh. Well that's nothing new. It's just VBR (variable bitrate) instead of CBR (constant bit rate), where the VBR of each channel moves up-and-down as needed.

I thought ALL stations were doing VBR.

But does VBR share bandwidth between simultaneously broadcasting channels?

No. VBR is one piece of the puzzle of stat muxing. You can have VBR and no subchannels or stat muxing. FOX network uses VBR. That is why you have people who don't understand how it works complain that FOX only does 10 mbs when in reality, the bit rate varies from 10 to 16 mbs depending on the payload demand of the scene, but to some of these people they will not believe it since they don't understand the difference between VBR and CBR.

Marc,

We were putting up an antenna and pre-amp for our new 2 Ghz. Digital ENG system. Not only are the stations transmitting to the public in DTV, but our truck microwave units are going digital. Nextel wants some our 2 Ghz band so they are equipping all US broadcasters with DENG as part of the deal.

We were not working on the Wx radar as it OK (this minute!)

You guys are going to LOVE it! We switched to the BAS bandplan in June and what an upgrade it has been! We had our doubts at first, but seeing is believing. Get get shots from places we had problems with before and the interference issues we had are all but gone now.

Yes. If for example the HD channel's bitrate drops from 10 megabit/s downto 5 megabit/s, that allow the secondary HD channel to use the extra bits for itself.

The process is a little more complicated because the computer has to divide the 19 megabit/s bandwidth between two separate HD videos, but it's still basically just VBR..... a very-old and well-understood technology.

OK, this is a question I can't find the answer to, anywhere...

Can someone actually in the Wilmington market confirm or dispel that the Trinity LPTVer, W51CW, is now in digital?

It was on the list of stations participating in the early transition, but I find no evidence it actually went along on September 8th...

Both WECT and WWAY (Jeopardy and The Insider) are showing logos for HD programming, i.e. each show is saying they are in HD, yet both are actually being broadcast here as SD...

??

Still manual switching to HD at 9PM???

More than likely, they don't have the equipment that's necessary to record Syndicated HD.

Hey Ray, Billy,

Do you have plans to air syndicated in HD soon, or haven't heard? That Bonnie Hunt is in HD, Ofrah is in HD too I think I read...

Oprah is available for airing in HD, but Bonnie Hunt isn't.

By wife also was complaining about "The Insider" not being in HD but having the HD logo. Not something I watch so didn't really care but would be nice to know when that going to happen to keep her from asking.

Bump!

Anyone? Anyone?

i believe it is...i can pick it up on my coverter box, which if it was not digital, i would not be able to.

thanks for the antenna recommendation! it is working great! i can't get the jacksonville my network tv station but i can get wilm and the other wilmington stations no problem.

does anyone know what the deal is the with wmyw station from shallote? how do they stay in business when virtually no one can watch them?
post #1558 of 2194
Is W51CW multicasting? Most TBN stations I've seen do, just wondering if they are...

- Trip
post #1559 of 2194
No, we are not broadcasting ET/Insider in HD at this time. We have no means currently to record an HD program. We do have very near plans to retrieve the show via SD widescreen and shoot that out. It is not the same I know, but its all we can do at the time.
post #1560 of 2194
So... to expand on that a bit, you are saying that the only HD you can broadcast is a network feed? Which I assume is "prime time" stuff starting at either 8 or 9 PM?

If/when local broadcast (like news) goes HD, does that imply you'll have the equipment to record HD?
