Madison, WI - HDTV - Page 151

I'm currently watching the Grammies on WISC, as I can't view the capture that I am doing until later.

The low bitrate that they are using because of their SD stream really hurt the Grammy video. It didn't take long for the flashing lights to drive the encoder wild.

I'll have to start a capture of the OTA version to do some side-by-side captures.

WISC has 1 SD Stream along with their HD? It should look pretty good compared to WDJT in Milwaukee. 1 HD with 3 SD sub's YUK!.

I can imagine, since WPT was doing that same thing, until they gave up after all of the complaints and dropped the 1080i to 720p. Needless to say, I don't watch PBS programming via WPT.

CBS is using 1.5 Gbps (uncompressed video no less) fiber to get the Superbowl from Miami to NY. They then feed the O&Os and affiliates via a two stream 4:2:2 MPEG-2 80 Mbps sat transponder.

Why bother. A majority of the O&Os and affiliates are destroying the video with a crippling bitrate because they have one, or more, SD streams. Even at the full allowable ATSC bitrate, it is barely enough for 1080i full action sports.

Probably sucks to be a number watcher. But for those that watched the game, awesome game, decent enough half-time show, great picture. Pretty good deal for "free" TV. But then, you wouldn't know, you don't watch sports

The numbers reveal the quality of the HD you are going to see.

I did have the game on in order to catch the halftime show. After it was over, I turned it off. But, after the Saints were kept from getting a touchdown and there was a shot of one of the Colts players running, the picture was a massive macroblock.

After I was finished capturing Masterpiece Classic (not via WPT), I went back and looked at a CBS network feed of that same video and clean as a whistle. I'll have captures later.

I didn't see the end of the game. But in another thread someone posted an image of the confettii and how it macroblocked even worse. Since I don't have a capture of that, I can't show what it really looked like.

Over on the Superbowl HD Technical thread, I posted a set of 10 image pairs. The bad being what WISC aired and the Good, what WISC received from CBS net, sortof. The stations got MPEG-2 4:2:2 at about 36 Mbps, while my grabs are MPEG-2 4:2:0 at about 40 Mbps.

Any idea when FOX will switch from channel 11 to UHF 49?
For me the sooner the better.

I have a dead 43" HLM-series Samsung DLP. Free to anyone who can salvage anything from it. It won't display video or audio. The light bulb doesn't appear to be blown, so I'm assuming it's the whole light engine. Leave a message at 608-228-1363 if you want to come and get it. Brooklyn, Green County. It will go to the dump next weekend.

Still working on it...may need to move back to 47. Problem is interference protection to other stations. Trying to get approval for higher power. Also, antenna location logistic issues.

Isn't 49 a clearer channel than 47, what with WTTW right there in Chicago? And isn't the power level for which WMSN is approved on par with the power levels of most of the other stations in the market?

WISC - 603 kW
WMTV - 155 kW (CP)
WHA - 140 kW
WKOW - 800 kW
WMSN - 280 kW (CP)
WBUW - 200 kW

If built, WMSN would have the third highest power level in the market.

Do not take it to the dump under any circumstances. Electonic devices must be recycled, as there are materials that can no longer go into dumps.

I can't get FOX 11 out of Green Bay because your on the same channel.
I live half in between. Can't get Madison either.

That is one of the reasons we're working on moving, but seem to have a few roadblocks!

I won't go into the technical reason why I'm monitoring WMTV.

But is it me or does the audio still have phasing issues? I won't be able to verify the audio until later tonight.

It most definitely does. There was one part of the Olympics coverage tonight where it really showed -- Bob Costas introduced a short video that was an olympics tie-in / preview for an upcoming Dreamworks movie, "How to Train Your Dragon" and the audio was all screwed up. It was like the center channel was gone or at very low volume, so you couldn't hear what the announcer was saying. This wasn't an ad run from WMTV, it was part of the Olympics broadcast from NBC.

Very frustrating that NBC still hasn't fixed this issue.

That is/was a problem with NBC, not WMTV. I'm talking about audio phasing issues. Bob would have been center channel and if the piece had center channel issues, that was the network.


Phasing issues aren't NBC's fault. I can reconstruct the 6 audio channels and not have a phasing issue. Unfortunately I did not capture WMTV in order to do an audio comparison.

OK then. I'll just file that under "miscellaneous sound issues that happen occasionally on WMTV that I haven't reproduced anywhere else."

Today while watching the Olympics on WMTV, my Sony surround sound receiver kept flaking out -- the front of the receiver shows which channels it 'sees' and two of them kept disappearing / reappearing, and each time, the sound cut out. This was happening like once every second or two. My wife's really into the Olympics and just wanted it fixed, so I didn't do much troubleshooting other than just switching to 2-ch stereo, which fixed the issue. I have never had this problem before in the 6 years I've had this receiver. After watching the Olympics, I turned surround sound back on, and it worked fine with other live TV and DVR recorded programming.

I have no answer to that one. I didn't watch the Olympics today. So I didn't have WMTV on, or the net feed. Was the other live TV WMTV, or other stations?

The encoding of the AC3 is definately controlled by WMTV. Since they get three stereo pairs that make up the DD5.1, and not AC3, from the network, everything that goes into the AC3 that is broadcast is via their encoder.

Did anyone else have issues with their DD5.1 playback of WMTV?

Not with the Olympics (not really into it) but the missing center channel seems to be a MAJOR ongoing issue. I watched Conan's last week, and the center was so low, you couldn't hear Andy during the lead up, Conan's monologue was hard to hear. Switched to Letterman, no problem, so it wasn't hardware on my end. Seems to me I noticed it before when Leno was on at 10:30. Makes me wonder if there is some goof-up going on switching from the local news to the network feed?
I did watch the opening ceremony, didn't notice anything out of order there.
On a side note, unrelated and probably off-topic. Was anybody else offended that they replayed the Luge accident time after time? And worse, showed the resuscitation efforts zoomed in. Used to be a time, at least in auto racing, that death crashes were not replayed. That all ended when Fox broadcast their first Daytona, and D. Earnhardt died. Just wondering if anyone else felt it might of been in bad taste...

When I get a chance, I'll capture a Conan Tonight Show from WMTV and NBC and see if there is a problem.


I only saw the opening ceremony and was not offended at them showing what happened. It was a news event of a unfortunate accident that should not have happened. I saw a portion of a NBC newscast a few days later and they are no longer showing the event. It was during a report of what they did to the track to improve the safety. Showing the accident is basically no different than when they show video of an airplane accident while the accident happened.

Just a little nitpick here... I watched that daytona 500... and normally I don't watch races, but for some reason I saw that, the car crashed on the last lap... the winner won, and coverage ended. It wasn't announced that Earnhardt died until much later. So at the time of race coverage, the replays were just of a crash, not of a "death crash"

Both. I haven't seen any more problems with NBC since Sunday, but we haven't been watching as much lately.


Yeah, I wasn't a big fan of that, either. I realize they're going to show the video anyway, but I wish they would've clipped it like the local stations did when they aired footage of that guy getting run over at the monster truck show at the Dane Co. Colliseum -- they didn't show him getting run over, they showed the video right up until it happened. I think they could've shown the video of the luger leaving the track, without showing him ping-ponging off the steel beams outside the track. It was gruesome.

You are correct, sir. But it was fox that broke into their evening broadcast with the race team to cover it. Not digging on Fox at all, just that at the time it surprised me.

I normally get my dose of Jeopardy! via other means. But I screwed up on Wednesday, so I had to capture what WMTV aired today (we use the final Jeopardy! clue at work right after lunch).

What surprised me is that I heard an audio phasing issue with that show. But it isn't a NBC sourced program. What WMTV airs is what is fed to them via PathFire. The audio track is just plain stereo (so is the HD version, which I view). What I heard over WMTV is not what I normally hear.

Interesting.

Could everyone please list what HD channels they're able to get over clear QAM right now? I want to compare with what I'm able to pull in. I used to be able to get CW HD but not anymore.

I'll assume using a TV tuner
3-1
15-1
21-1
27-1
47-1
57-1

Just like OTA oddly (and nicely) enough.
You didn't ask, but the subs are in their appropriate slots
3-2 MyMadison or something 14
15-2 Weather, sort of
27-2 The rerun channel
27-3 This is another channel
21-2 Yup more PBS
21-3 and still more
none of those are HD

if memory serves me, someone a few pages back was having difficulty with the CW. I think it was that the programming he expected to be in HD was not..you could do a search for CW, or I am sure someone with better gray matter will respond

I get these for Janesville WI QAM thru Charter

21-1 WHA-HD
21-2 WIS
21-3 Create
27-1 WKOW-DT
27-2 RTV
27-3 THIS
47-1 WMSN-DT
57-1 WBUW-DT
85-8 TVW-SD
106-3 NBC-15 Weather Plus
106-5 NBC-DT
106-6 WISC-DT
