Detroit, MI - HDTV - Page 5

post #121 of 11764
Has anyone else noticed random 1-2 second audio dropouts on the Detroit digital ABC channel? I'm watching on Comcast (channel 180).

The last three nights I've been getting annoying audio dropouts -- during desparate housewices, monday night football and just now on the seven o'clock news. All other channels ae fine and the analog ABC is fine.

I noticed this exact same thing. I have the HD Tivo box and my wife noticed bad stuttering during desperate housewives on Sunday. Last night - MNF through the antenna, 7-1 was horrible, although regular channel 7 through the antenna was fine. What receiver are you using?

Same problem here with Comcast. Plus, Shay Ryan not doing the weather is not good either.

I've been assuming I'm the only one with this (WXYZ-DT) problem, since nobody else has mentioned it. I, too, have the HD-TiVo, and signal strength meter says 85-90, yet these annoying, intermittent audio dropouts and video freezes are occurring on a seemingly random schedule over the past ten days or so.

It doesn't blank out the screen, or dissolve into a bunch of random blocks of color, like I'm used to seeing when multipath rears its ugly head and the signal gets dropped. The picture just freezes and holds steady for a second or so, then resumes updating. Sometimes this happens in rapid succession, with accompanying audio silencing.

Sometimes it's just the audio that gets momentarily interrupted, and that, too, happens differently than the "normal" signal loss. My audio receiver has an LED that turns off when the digital audio bitstream stops, and that LED stays on during these audio dropouts.

All this makes me think that either the transmission is messed up, or somehow the HD-TiVo has a problem - but only with this one station, and only since about mid-November. Is either of these possible, or is this just a different manifestation of an antenna problem?

Further observation:

When WXYZ first started broadcasting the ABCNewsNow network on WXYZSD2 (41-3), I occasionally tuned it in, and experienced this same sort of problem with audio/video freezing, even when the HD channel (41-1) was perfectly clean.

I just switched from the Damon Wayans show on 41-1, which was displaying the freeze issue quite a lot, to 41-3, and watched for 30 minutes without a single glitch (got to see the Denzel Washington Boys & Girls Club PSA at least fourteen times, too ). When I switched back to 41-1, there were three or four dropouts in the first minute.

It seems that somehow, those two subchannels have switched places, at least in terms of how well my receiver handles them. I wonder if WXYZ engineering would know why?

Yes. Same problem here with ABC on Brighthouse (CH. 270) Very annoying.
post #127 of 11764
I noticed it too during My Wife and Kids (OTA through a Voom box), but it was the first I had seen it and figured it was just an issue with that show. I've been flipping to WXYZ since then and haven't noticed it during According to Jim, or Rodney. But I haven't exactly been glued to these shows. Whatever it is, I hope they get it handled before Lost tomorrow night!

Just watched NYPD Blue on HD Tivo and had short audio and video dropouts.

Wow and I thought I was the only one. Yep, I'm getting audio dropouts on 7-1 also using the HD TiVo. Happened during Boston Legal and Desperate Housewives (2 of only 3 shows I catch on ABC). I'll find out if it continues and starts happening during Lost (#3) tonight.
post #130 of 11764
We just watched last Sunday's Desperate Housewives broadcast on our HD TIVO and there were a lot of audio/visual dropouts, especially during the first 15 minutes. We've noticed this before on CH 7-1 but never this bad.
post #131 of 11764
Good to know that it's not just me experiencing problems with ABC.

On a happier note, I just got my dual tuner 6412 DVR delivered by Comcast today. Install fee was $21 but they were late so I get a $20 credit. They said they were late because there were no 6412s at the warehouse this morning but then they came in so the guy had to go back to get it.
post #132 of 11764
I'm just not comfortable waiting around until they "handle" the problem.

Does anybody have any contacts at WXYZ to make sure they're even aware of it? I tried the generic e-mail last night ("attn: engineering" in the subject line), and even referenced the fact that different OTA receivers and cable subscribers were having the same issue. As expected, I haven't gotten any response whatsoever.

I would have guessed that, if the cableco's are having this problem, they would have some sort of QC watchdogs on 7's a$$. Either I guess wrong about them, or they're getting stonewalled, too.
post #133 of 11764
Comcast sent my 6412 this week, the tech was late here as well. I might have to get a replacement for mine. Component video works fine but s-video (which I want to use for a 2nd input) and composite are not working.
Still, it's nice to have the 2 tuners and the bigger HD, I can work around the dead outputs for the time being.
post #134 of 11764
Crap. WXYZ still rockin' the dropouts/stutters/whatever during Lost. Muy annoying.
post #135 of 11764
Add me to the list, I figured it was something on my end but it seems a lot of other people are having WXYZ problems too. Hopefully they can correct it.
post #136 of 11764
I also have the WXYZ audio dropout problem. Cable company on channel 7's but? Hardly. I called Comcast, where I get my signal, to tell them about it. They sent out a technician. He said he'd never heard about this problem. Then he looked at my setup and said "geez, this is really complicated...I'd call my audio guy to check it out". I told him I'm the audio guy. He just stared at me, checked the signal, and said it was fine.

I too, would like some way to contact channel 7. ANy suggestions on how to get through to them?
post #137 of 11764
Hey people, pick up the phone! I didn't have a chance to call today, but if you call during business hours and ask for engineering or the chief engineer I've always gotten through. I've called many stations over the years and most were glad to hear I was watching their DT feed and were very willing to attack the problem.
post #138 of 11764
I watched Lost last night,I had no problems,I have not watched Channel 7 all week until last night so I have not seen any earlier problems,OTA with a E* 811.
post #139 of 11764
I checked the signal and it is down to 83% where it is always in the high 90's for me,but I don't know how that affects Comcast.
post #140 of 11764
I'm pretty sure this isn't a signal strength or carrier frequency reception issue. Rather, it seems to be some sort of encoder/decoder mismatch problem, which apparently doesn't affect all receivers equally. I know virtually nothing about the technology at work here, so I can't speculate on the real root cause, but I can at least make empirical observations.

Judging from the comments here, this issue seems to affect some DirecTV HD-TiVo and some Voom receivers at least, plus at least some of the Comcast and Brighthouse systems. Apparently, the Dish receiver is not affected.

This is all good info to pass on to somebody at WXYZ, if they'll hear it. I really don't have time to call today, but I can do it tomorrow.
post #141 of 11764
I called, and asked for engineering, but had to leave a message. We'll see if they call back.
post #142 of 11764
Amazingly, they did call back, and promised to work on it, and keep me informed. I will do the same with them, and let them know if the problem persists, and if/when it is fixed.
post #143 of 11764
Good job, Kreisman. Please keep the rest of us informed. Thanks.
post #144 of 11764
Just thought I might add that I have WideOpenWest and have been experienceing the same problems with ABC through the HD box. I seem to get better results with the OTA than the HD box. Overall I have been very unimpressed with the HD cable services. Seems like a waste of $15 a month to me.

somewhat OT - Can anyone explain the difference to me between say channel 7.1 and 44.1 or whatever the other ABC channel is? My set doesn't detect all the HD channels and it sucks to have to manually punch in the numbers everytime. Can't figure out a way to add them manually.
fyi- I'm using a Sony WDF-42WE655
post #145 of 11764
I am getting audio drops and video pix on ABC, FOX and NBC...via Comcast, I have the dual tuner box now, but this happened with the single tuner as well

HELP
post #146 of 11764
Hello all, HD newbie here with a few questions.

I recently purchased a Sony Grand Wega IV, 55"" WF model and had WOW HD installed today. Unfortunately, they showed up early and installed before I got home.

My understanding is that the TV's native resolution is 720p. The box (SA 8000HD) seems to send everything out in 1080i according to the display on the TV. Since most of the channels are actually broadcasing in 720p, does that mean that first the cable box is converting 720p to 1080i and then the TV is converting it back? I'm sure this would degrade the picture. Is there any way to tell the cable box to output 720p?

Also, I currently have it hooked up by component cables. I'm unsure if the DVI port is activate on the cable box. Does anyone know? If so, would this then send the native signal to the TV?

I also noticed that the picture on non-digital channels was far worse via the box than a direct line into the TV. I actually added a splitter so I can watch SDTV through the direct line. I'm sure this split doesn't help either. I also tried hooking up an S-video cable to a different input on the TV, but no signal was there. My thought was that possibly non-HD would look better through S-video.

Right now the signal looks very good to me on native HD broadcasts, HDNet in particular, but I think it should be even better.

Sorry for the rambling. Any suggestions much appreciated.

PS. I'm rather new to this forum, would it be ok to post this same question in the Sony Grand Wega iV thread?
post #147 of 11764
I'm interested in any responses you get too. I actually was wondering the same thing myself today. Apparently there may be a pass through option on the STB but I haven't had a chance to investigate this yet. I would suggest posting in the Grand Wega forum as well. You may get more model specific answers there.

Go to this link, http://www.scientificatlanta.com/exp...ub/default.asp, and register for free. In there is a HDTV wizard which will show you how to set the DVR up for 720p, but most of the channels out there are 1080i, ABC, Fox and ESPN-HD are the only 720p stations that WOW has.

The DVI port is disabed on the 8000HD. SA released the new firmware which enables it, but WOW hasn't finish testing it yet.

Also, as of right now the box doesn't have the option for pass-through, the SA 3250HD has the option if the new firmware is on it, I never looked when I had it because my set cant handle a 720p feed so it was irrelevant to me, sorry.

Looks like we will be getting the Fox sports package on our Comcast system soon. Six channels have shown up starting at 262, one of the channels looks like it is Fox Sports World (English Premier League Soccer).

Been waiting for this for a while, called Comcast service rep was very helpful, he said that they hope to have the channels on my the end of the month. Asked about ESPNHD2 in January and he said we would be getting that too as demand for sports is high.

So the theory to use the pass-through option would be correct then to allow the set to utilize whatever it likes best?
