post #2101 of 4529
Sorry if it's been addressed already - I searched through this thread quickly and didn't notice anything...

But is the macroblocking (I assume due to overcompression) on WPXI a local problem or an NBC issue? Whenever their is quick movement there are macro-blocks everywhere. Very distracting to me.

Thanks for any info on this issue.
post #2102 of 4529
Good morning Jantzen...

The macroblocking issue had been addressed by NBC when they discovered some changes which needed to be made to the encoders at the affiliate level. We made these changes, and I was under the impression this had been solved. Quick question for you - have you rescanned your channels recently? I know this sounds like a silly request, but I understand that this can help sometimes. I will address the macroblocking issue once again (I assume you noticed this during football, correct?).

The bigger issue I am dealing with right now is lip sync problems. If any of you notice lip sync problems, I'd appreciate you sending me a message through the forum. If you would include the program, the date and time, and the make and model of your receiver, this would be greatly appreciated. The occasional lip sync problem is a tough nut for me to crack.

The NBC football games have not improved. They are still bad. From the empirical evidence and feedback on these forums, the poor picture quality of NBC HD broadcasts with fast motion, such as the ND football games and NFL Sunday Night Football, are largely because of the subchannels (Weather Plus) starving the bitrate. This is a problem all over the country with NBC, but apparently the problems don't exist in the original production because HD clips of NBC games shown on ESPN-HD look flawless.

Check out this thread from the HD Programming subforum (just the latest of many complaining of these problems):

http://www.avsforum.com/avs-vb/showthread.php?t=724854

Can't WPXI at least try an experiment and just turn off the weather subchannel to give the games the full bitstream they apparently need in order to look good? I find it hard to believe that anybody would complain if that weather subchannel disappeared for a few hours during high profile HD events. The current state of affairs make the network and affiliate stations look bad. We survived just fine without the weather channel all these years. I could certainly live without it.

I don't know the whole story, but I'm not holding my breath that WPCW will have a digital signal on the air anytime soon.

Early this year (in February, I think), the FCC finally gave WPCW permission to use channel 49 for it's digital signal and WPCW applied for a construction permit. Unfortunately, that's now been challenged by the owner of a low-power TV station in Indiana, PA which is using the same frequency.

The FCC had told the Indiana station it would have to move to another available channel, but its owner filed objections in June to WCPW's application, claiming there were no suitable channels for it to use. WPCW has petitioned to dismiss the challenge and has asked for an expedited ruling. But given the FCC's track record, I don't believe we'll see a digital signal from WPCW in the near future (after all, it took the FCC nearly *seven years* to approve WCPW's channel change application). Hope I'm wrong, but even if approval comes soon, I think the FCC's handling of this issue has been nothing short of pathetic!

There's more to it than just shutting off the few MB the Weather Channel takes up. There was a post last night from someone who saw the artifacts on a station that didn't have any subchannels. Here's the post.
The incoming NBC feed is excellent, it boils down to encoder settings, firmware, and generation of the encoder at the stations. As a matter of fact I've noticed over the past few weeks there's grumbling about Fox, CBS and ESPN too depending on the market and source. The fact remains that we're going from 1.5 GIGA bits down to 19 Megabits. That's almost an 80 to 1 compression factor.
Now I'll duck and cover!

Dave and/or Dave

Any update on when Dishnetwork will have local HDs available? Many Dishnetwork owners in the Pgh area are dying to get the football games going. This was promised back in March, but it seems like they are doing absoluetly nothing.

Thanks Dave

I was hoping for some better news. Sad they have put people in this position of deciding between keeping our satelitte receivers or switching to cable.
post #2109 of 4529
not sure if it will help, but there has been lip synch problems on the first 2 NFL games on nbc. both the steelers opener and this past sundays game.
post #2110 of 4529
Dishnetwork said end of 2006 or early 2007. Talked to them last week. so have no idea when we will get any HD channels.

Is anyone else having serious audio sync issues with KDKA?

I tried to watch a few of the season and series premiers this week but they have all been around 0.8 seconds out of sync.

The Unit, NCIS, Smith, and Jericho were all horribly botched.

The audio sync is so bad that KDKA programming isn't worth watching really. It could be my equipment... but why is it only CBS/KDKA?

I could be your equipment. I have only watched NCIS, but it was fine. My receiver is a Tivo HR10-250 from DTV.

CBS (KDKA-DT) is the only network I have sync issues with. Letterman is off by almost a second - it's like watching a dubbed Japanese sci fi flick from the fifties. NBC, ABC, FOX, WB, and PBS HD feeds have perfect, in sync audio. Using an Echostar Model 6000 as one source with an OTA, and a Sony DHG HDD250, also with the OTA.

The funny thing is, that when KD goes to a local insert during network programming, the audio is fine for local content. I have a friend with a comcast dvr box who is having the same problems with KDKA in Tarentum...hmmmm.
post #2114 of 4529
I noticed the KDKA/CBS lip sync issue last night on Shark. It was way less than a second, but it was there. And not there on local. I have an SA box from Adelphia. I did not check the OTA.

I'm watching KDKA in Johnstown via Atlantic Broadband (Scientific Atlanta STB) and have noticed a few lip sync "events" but they have been brief and sporadic. One of the common suggestions I've seen posted elsewhere on this forum is to try remapping the channel in question. Good luck.
post #2116 of 4529
I've read through this forum throughout the last few days and I'm still in need of some help. I want to avoid comcast HD and get the OTA HD. I get a pretty good signal on KDKA, I get Fox somewhat but it does break up a good bit. I have a basic set of rabbit ears for now, so I'm guessing a better antenna would help out. I've taken a look at the antennaweb and it gave me an area to focus on for my coverage. I'd like to stay on the cheap end for an antenna ($50 or less) and indoor if possible, or at least attic install. I've seen a ton of different antennas out there and I'm not sure where to go from here.
I'm expecting that WTAE will be the hardest since it says I'm about 20 miles on that signal, but that is as far as I would need at least.
Any help is greatly appreciated folks.

Thanks

Channel Master 4228 is the best for uhf HDTV OTA. I bought mine from www.solidsignal.com
post #2118 of 4529
Is anyone else having any recent problems with their OTA reception of KDKA-DT? Normally my signal strength is a solid 100% for KDKA-DT but for the last few days it has been running around the mid 60's or lower. The channel's signal strength has occasionally dropped off low enough that I totally lose the signal. All other stations I receive OTA are still showing the same signal strength on my receiver so the problem seems to be with KDKA.

Have you had any leaves fall near you? This time of year, the foliage changes can make a difference.

KDKA has always been at a signal strength of 100% at my house. This is over several years and has been independent of seasons. Leaves or the lack of them on trees have never had any noticeable impact on the signal. The signal strength of all the other PGH channels I receive have not changed. All of them come in at 100%. This include WTAE which some people apparently have had problems receiving. I'm getting D*'s newest HD receiver installed later this month. I'll have to see if that fixes the problem. In the meantime maybe I'll play around with the alignment of my outside antenna to see if that helps.
post #2122 of 4529
I've had OTA problems the last week or so with every station. I think it may be related to the TiVo 6.3a update. But I have a 4228 on the roof (North Hills) and rabbit ears inside and neither is working worth crap right now.
post #2123 of 4529
I've been having problems with my OTA reception lately. I've had to move my antennae (CM 4228) about 40 degrees to pick up everything that used to come in and I can't get WTAE at all now. I may have to watch Lost in SD tomorrow!!! I'm in Plum near New Kensington using a Dish 811 as my receiver. Could it be fall foilage?

It could be fall foliage or it could be the fact that WTAE is pretty much in a completely different direction from all the other networks. Combined with autumn and the nasty rain we've had, and the fact that the 4228 IS a directional antenna could contribute to you not getting WTAE. I also suspect that WTAE's broadcasting antenna is obscured by hills which weaken the signal already though I've yet to confirm that.

Using antenaweb, I see that from a generic location in Plum, you should aim your antenna SSW and see if you still don't get signal.

I personally have to turn my antenna any time I want to watch WTAE, and I'm in Squirrel Hill.

Hello, I am new to the hdtv arena. I have recently purchased a Sony 40' LCD XBR2 series tv. I live in the Moon Twp area just past the airport and close to the Beaver County border. With an old two post antenna from a 10-15 year old tv, I am able to pick up channels NBC, CBS, Fox, and just recently with the posts set to about 12" in length and pointed in the general direct I can get ABC, which is about 29 miles from my location. I have tried a few indoor atennas from RCA, powered units, but none perform like this old two post antenna. ABC will drop if someone walks infront of the tv, but I can live with it. Now, I would like to try a good quality indoor uhf antenna. If I could just get PBS to come in everything will be perfect. Antennaweb recommends a large antenna for pulling in ABC. Now, some questions.

1. How is this antenna pulling in abc? it has a flat cable connecting it to the tv. the cable is only 12-18" long. It does have nice hefty diameter poles, compared to the cheap RCA posts.

2. With a good quality uhf indoor antenna, do you think I could get ABC without the dropping if someone walks threw the room?

3. Any recommendations on a good performing indoor uhf antenna.

I called Laketon TV and they will install a roof top antenna with all the other necessary parts for $299. Now that I am getting ABC I am reluctant to pay, with the performance from this old antenna.

Thanks for any tips, comments, suggestions.

Bob

I bought a Channel Master 4228 and rotor at solidsignal, a mast at Radio Shack and used a fiberglass pipe I had laying around for the pole. I had Venus Satellites install it on the side of the house, they used a diplexer on the exisiting satellite cable run which works fine. I usually get signals that jump around from 85 to 97 percent or so. KDKA drops out rarely, WPXI is solid, WTAE was decent unitl recently it's non-existent, WPGH and CH22 is solid (CH22 also has The Tube) and WQED is solid and very nice. I was actually picking up DTV from Altoona/Johnstown.

1. You may be lucky or you may actually be picking up a reflection from somewhere.

2. Without expensive tools, this is impossible to say with any certainty. Indoor antennas and reception with them is based on Voodoo :-). No, not actually, but there are times back when I relied on a small indoor antenna where the signal would cut out a lot, and I couldn't figure out whether it was me walking across the signal path, or if it was the weather for the day or the alignment of the moon (Signals shouldn't cut out on a good clear winter day, right?)

3. The Silver Sensor is considered by many to be one of the best typical indoor antennas. I'm able to get every channel but WTAE with consistency (WTAE was inconsistent with me). However, depending on what you consider indoor, the silver sensor doesn't hold a candle to other antennas. I purchased a Channel Master 4221 and keep it in my attic with a very long wire running down to my TV area. Even with the long run, I got better WTAE reception than with the Silver Sensor (as an added bonus, the long run acts as a semi-decent VHF antenna as well). I watched the Steelers beat the Seahawks with no picture drop out with the CM4221. This never would have happened with the silver sensor.

Does anyone know when Jeopardy and Wheel of Fortune will start being broadcast locally (WPXI-TV/DT) in HD? The broadcasts and EPG say they are in HD, but the actual program doesn't look like it...

I went and bought the Silver Sensor but it could not pull in channel 4. It did get all the others i currently get. Oh well, I am just glad I have this old antenna, I guess that just dont make things like they used to.

One more question, what is the difference between a uhf and vhf antenna. I thought these two post atenna's where vhf antenna's? If so, I am really confused about why it is working so well.

Btw, there is a Heros marathon Sunday night starting at 8pm. Broadcast in HD and a pretty cool to boot.

You're right, the local programs are not yet being broadcast in HD. We are working through a closed captioning issue right now, and I suspect that as soon as we get that resolved, we'll be broadcasting Wheel and Jeopardy in HD. Sorry, I don't have a date for you on that yet.
