I don't care if there's a performance by choirs of angels... 5.1 sound is not worth the frustration that this is causing.

Sorry for the problems but I appreciate your efforts. Glad to see the HD feed back. We have 2 channel stereo. Still lots of break ups on the heavy filtered scenes.

Tom,

Don't be too discouraged or frustrated. It is a learning experience for all of us, and most of all, we know it will get better and better.

Looks like, "Without a Trace" is much better.

Thank you for trying.

See Tom, just takes a few choice curse words, and a little bit of patience inbetween the chaos of it all. thanks for the hard work. I'll toon in on sunday and enjoy your good work.

Anyone else have trouble with ER on WTHR the last few weeks? Something was up with the pixel alignment that I have never seen on any other WTHR show, for that matter any other channels.

I started to notice things such as the wheel on Wheel of Fortune seemed to be in some time delay when the picutre was drawn, I could see the picture scan from side to side. Then durring ER it seemed there were colums that were a few inches wide and a few pixels off from the adjacent colums.

Anyone else seen this? Im starting to wonder aobut my equipment.

A friend of mine was just asking if I had noticed some weird problems with ER the past 2-3 weeks. I haven't watched it but your comments seem to confirm what he said. The non-HD sitcoms were okay but once ER started it was not looking good.

I'm here and ready for this to go well - keep your toes crossed ! One thing that didn't get done because of insufficient testing time is switching - so don't look for audio on the local commercial breaks. I'll switch to 5.1 during the end break of 60 Minutes, and back to 2-channel when the Grammys are over.

If the rumor's true and Simon & Garfunkle sing together, it may be better than choirs of angels for this folkie !

If it appears that things don't set up right, I -may- have to reboot the encoders - so don't panic if the signal appears to disappear for about 2 minutes right at the very start. Hope I don't have to!

My receiver is showing 5.1...

...The sound is way off from the picture. Maybe the sound is 2 seconds before the video.

Edit to add I see you are rebooting.
post #160 of 6947
Still way off in sound. It seemed to be good for a few seconds after the reboot but then the video froze or cut out the the sound was lost and then when it came back, it is off...

It does sound very good and looks very good.

Edit to add No Doubt is dropping audio frequently. The stobe lights cause pixelization out the whazoo...
post #161 of 6947
The audio is just ever so slightly off now since you went back to 2 channel stereo.
post #162 of 6947
F!

post #163 of 6947
Tom,

it is 2 channel stereo now?

by the way, picture quality is great, audio is great (when it does work .. 5.1 rules!)

Faith Hill - Words Escape Me

Sound going in and out and sync getting worse in 2 channel stereo.
post #165 of 6947
The blue cloud scene with the Dixie Chicks cause the audio to drop completely and major picture break ups.
post #166 of 6947
I had major breakups during the Nelly Songs
post #167 of 6947


Nelly (with Kelly Rowland) was completely unwatchable with all kinds of break-ups with the colored scenes. These are just like the problems we are seeing when watching CSI.

Tom, I have to think this is the result of Channel 8 running 2 extra channels. I would like to see those channels go away so maybe we can have the additional bandwidth for the main CBS feed. Nobody else locally has 2 subchannels.
post #168 of 6947
I dont know what is causing the breakups.. but my signal was rock solid the whole time, so I feel confident ruling out my equipment.. I hope this gets resolved.. it kind of kills the whole HD experience.. NOTE: after reading Jims post I feel confident this is a WISH problem.

Edit: I want to explain why I feel this is a wish issue. With Jim and I having issues with the Same song at the same time it cant just be coincidence. Thats all!

Tom I know you work hard to bring us the best, just wanted you to know that I appreciate your hard work, and for putting up with us who always demand more of you.
post #169 of 6947
Zotz! A moral victory, in that 5.1 surround was on the air - briefly. Based on Friday's test time, there was just a little delay between audio and video - not the 2 seconds or so that we experienced tonight. I tried a couple of things, but I couldn't in good conscience keep playing around on-air with a high-profile show like this.

On Saturday I was able to work with one of my guys who was at the transmitter. He saw the breakup on high chroma at the transmitter site but before it went into the transmitter. But I have not seen the problem fairly late in the chain at the studio - so I'm down to only about 2 or 3 devices now. I have a "spare" for one of them, so we'll keep working at diagnosing this.

Keep the faith (hill).

Tom,

Thanks for your dedication and hard work last night. Getting the new equipment at the last minute was definitely not the ideal situation for you and your engineering crew at WISH. We know you'll have things worked out very soon.

I was just checking out the WFYI website and found this.......





I just spoke to an engineer at WFYI about digital ch. 21 and he said the station is currently running at 75% of licensed power due to a problem with the station's antenna. He said that as soon as it is repaired the station will crank the power to 100%.

I am not going to be much help here, but just wanted to chime in that my signal strength on channel 9 has been hanging around 20 for the past couple of days. I still get 45,46, and 25 at 79-100%. Would any of the changes made lately effect my basic reception of channel 9? Previously, 9 was my problem channel because it flucuated enough to cause break ups, but usually the signal was in the 70's. I am located about 70-80 North of Indy and use a roof antenna with winegard pre-amp connected to a DST 3000. It is great to see direct support from an inside engineer in the forum and I was eagerly hoping to see the Grammy's in HD 5.1. When you get everything figured out, can you come up here and show the guys at WLFI how to make it work smoothly. I hear they are gearing up and should be transmitting HD in April.
post #173 of 6947
We have some responsibility for WLFI (we're owned by the same company), so we'll definitely be assisting them in getting HD up and running.

Sorry it won't be till April, but some of the equipment isn't expected till then.

Interesting that your reception of 9 is significantly worse than the UHF stations - not usually what one expects. How do 8 and 13 come in?

That's what I always wondered, my UHF DTV stations are typically 90-100 and 9 is around 70 signal strength. Then I saw in some thread that WISHDT is only at 20kW where most of the other DTVs are closer to 100kW of power. Is that true?

I'm probably going to be looking at for a pre-amp soon to help with the marginal signal strength problems that seem to pop up for some reason (weather/???).

Generically speaking.... VHF doesn't require nearly the horsepower that UHF does for the same coverage area (as I understand it).

I don't know what the ratios are exactly but it is quite a difference from what I've seen.

Here in Bedford, IN I can SOMETIMES get WRTV DT25.... and a -bit- more likely WTTV DT53.... Rarely can I get enough signal for WISH DT 9 to be viewable tho.

Steve,

I'am getting WFYI DT her in spencer about 80 on the meter. Fianally PBS.

Tom,

I checked the reception on analog 6,8, and 13. They all come through with a solid picture, but they are washed out with a static over haze. Not a very technical description, but I hope you get the idea. For the past few days, I can't view 8-1 at all and the signal from 9 is showing around 20. It is not always like this. I was able to watch all the playoff games in HD with only occasional freezing. Just wondered if there was a change recently that would explain this. I do have a rotor and adjusted for the highest signal, still no luck.

Brad,

Thanks for your signal report of WFYI-DT from Spencer. According to the station engineer I spoke to yesterday, I'm the only one having reception problems. While all of the other Indy DTV stations are fine, I'm still getting a very weak and erratic signal from WFYI-DT at a distance of only 6 miles.

I'm starting to think I live in the Indy DTV "black hole." About 18 months ago when I first installed my outside antenna, using the CM 4221 (4-bay bowtie), I got great results from all stations except from WXIN-DT, 45. I got absolutely no signal!! I then started experimenting with other antennas and then the signal from ch. 45 was fine. The only place I could get a steady signal from WXIN-DT with the 4221 was with the antenna sitting on the floor in my basement.

I've already tried two different antennas for WFYI-DT with no difference in the results. I'll keep experimenting. I'll let you know when I really start having fun!

post #179 of 6947
As was mentioned, VHF channels typically carry farther than UHF channels, so at a distance (Bedford, or Lafayette, for 2 examples), I expect 9 to be viewable more of the time than the UHF stations, with -equivalent- power.

In the analog world, for instance, a UHF with 5 million watts should get out at least 50 miles. But a VHF 7-13 might get 55 miles with 316 thousand watts.

There are of course, about a zillion variables including transmit and receive antenna designs, terrain, co- or adjacent-channel interference, etc. etc. etc.

Oddly enough, I have never had reception issues in Kokomo with any Indiana station. Even channel 20 (21) in testing comes in strong. I just have a basic Channel Master with a preamp on my roof.
