Could the encoders be programing to keep sending the DD5.1 signal even during the glitch times instead of just blanking?

I've seen glitches that I couldn't hear and it seems from reading here that some of these other AVRs are cycling on some of these extremely short glitches, thus causing the viewer to lose 1 to 2 sec of sound that wasn't that long of a glitch in the feed. If the feed could keep these locked onto the DD5.1, so the AVRs didn't cycle, it seems a fair amount of the dropouts might be reduced. Some dropouts don't seem to be real [in the feed but merely a loss of the Dolby bits] and others are longer but seem to be less than a second [to my ears on those I heard] so if the AVR didn't have to cycle then these would only be small dropouts.


VOS, you (and Stuart) may be onto something. When I turn my AVR on, or switch to, my AVR takes 1-3 second longer to come on than it does using other audio source materials. Since my dropouts while watching D* recorded material is 2-4 seconds, the differing one second may be that glitches. Also, the glitch could be one second, but with the AVR recovery/recycle time it might explain why I complain of 2-4 second gaps.

Please, let's keep this thread productive.


Though somewhat off-topic due to the differences in problems, I've experienced some interesting audio issues on a couple of "local" channels after LIL was launched in my DMA Wednesday. Those issues (along with other non-audio related issues) were reported HERE and HERE.

Basically, two of the HD channels included in the LIL channels have audio problems. WABW (GPB/PBS 14) has absolutely no audio except for occasional blips. WCWJ (the Jacksonville, FL CW affiliate imported into our DMA) has the same issue, but only when HD programming is airing, as SD programming plays fine. This issue is with both the unit hooked up to an AVR and when connected via composite to a SDTV.

What does this have to do with the price of Coffee in China?! Well, I was reading this post:

I've seen glitches that I couldn't hear and it seems from reading here that some of these other AVRs are cycling on some of these extremely short glitches, thus causing the viewer to lose 1 to 2 sec of sound that wasn't that long of a glitch in the feed.


... and I realized that the issues with these local channels are essentially the opposite of what we experience with the national channels.

With my SDTV hooked up via composite, you just notice that PBS has no audio (essentially), but when I viewed the channel with the HDTV/AVR, I realized the similarities in the issues. With the national channels, audio will be just fine... and every now and then, the audio will cut out and the AVR will display this momentary drop in audio. With the "local" channel(s), audio will be missing, and every now and then, "audio" will appear, and the AVR will display this momentary "blip" of audio. With The CW, it's different in that the audio is consistently cutting in and out (whereas PBS stays silent more often not), and in the fact that it only happens when The CW is showing network (HD) programming.

Again, I realize this is a "little" off-topic, and may have little to do with the issues in which this thread is intended to address, but I found the similarities... or differences, depending on how you want to look at it interesting. Others may disagree...

Since Royal Pains on USA was one several watch here's what I had tonight:
First came @ 18 min
Next @ 35 mins but I couldn't hear it and only saw the AVR cycle and replayed it three times to make sure.
Then @ 42, 49, & 57.
Most I did hear but if a second is "one thousand" long, these were "on..." long.

So with what I've seen with the two difference Sony AVRs and the HR24, along with reading what others are having problems with.

Stuart Sweet had an idea that sparked a thought.

Could the encoders be programing to keep sending the DD5.1 signal even during the glitch times instead of just blanking?

I've seen glitches that I couldn't hear and it seems from reading here that some of these other AVRs are cycling on some of these extremely short glitches, thus causing the viewer to lose 1 to 2 sec of sound that wasn't that long of a glitch in the feed. If the feed could keep these locked onto the DD5.1, so the AVRs didn't cycle, it seems a fair amount of the dropouts might be reduced. Some dropouts don't seem to be real [in the feed but merely a loss of the Dolby bits] and others are longer but seem to be less than a second [to my ears on those I heard] so if the AVR didn't have to cycle then these would only be small dropouts.
While not perfect, it might [if it can be done] go a long way to improve the listener's experience.

Just a wild thought that came to mind and have no idea if it would work.


VOS, you (and Stuart) may be onto something. When I turn my AVR on, or switch to, my AVR takes 1-3 second longer to come on than it does using other audio source materials. Since my dropouts while watching D* recorded material is 2-4 seconds, the differing one second may be that glitches. Also, the glitch could be one second, but with the AVR recovery/recycle time it might explain why I complain of 2-4 second gaps.


I tried the Onkyo TX-SR806 along with the Yamaha RX-V465 before settling on the Yamaha. The main reason, besides price :lol:, was the drop out "clicks." The Yamaha would blip for a quick half second, but the Onkyo would need like 3 or 4 seconds to recover on the exact same drop.

IMO, this shows how some folks might really be affected to a larger & more frustrating degree depending on their AVR.
If you stop responding to them or put them on ignore, then eventually they'll go away.

It might also explain why I (and I'm sure others) have written off people's complaints about the problem as being too "dramatic". I find the audio dropouts to be annoying for sure, but I've rarely had it dampen my enjoyment of a program.

BTW, the "clicks" on my old Onkyo used to bug me. So glad I don't have them anymore with the Pioneer! :)

Last night, the wife was watching BravoHD, The Real House Wives of DC... the drop outs were so bad, it was like watching a silent film.

Seriously, the attention and the time to resolution is Horrible with this issue. D* and everyone else who is "in the know" can keep saying they are working on it... but honestly, they are going to loose my family as a customer, we all spend so much money on equipment and you can't even enjoy it. What the point of being the HD leader when you can't hear the content in Surround Sound in an enjoyable way. Poor Form!

VOS

I started watching Royal Pains on USAHD last night about 9:30 cst last night.
Basically, I got the same drops as you.
I got a drop at 35 min, 42 min, 49 min, and some pixelation but no audio drop at 54 min.

Thanks for the credit, VOS. Unfortunately I had to clean up a few more off topic posts. Please, let's keep this thread productive. If the overwhelming feeling is that we can't go a day without venting, I'll open a thread for you to complain but I'd much rather you expenses your energy documenting the issue.


Stuart,
As a complainer, all I really want to know is that DirecTV views this as a legitimate problem and someone is working to correct it. I believe that the delivery of DD5.1 via MPEG4 is the issue. Granted it looks to be an encoding problem, but the end result is that my enjoyment of this enhanced audio is degraded due to this problem. I am obviously not alone.

I would like to say that DirecTV has done a very good job of delivering their HD video via MPEG4 and MRV. I am truly amazed some times at the quality of the picture. If they can handle the video, certainly they should be able to clean up the audio.

Thanks!:)

Tonight we were watching Pillars of the Earth on Starz (recorded but only about 20 minutes behind real time). For the FIRST time in a long time, there were NO audio drop outs at all while watching. We have had dropouts on virtually every channel. Now this is on a HR24-500, but I thought I would report what we observed. I have no idea what problems are relative to the HR24 or the other DVRs... we have three others which are not HR24s. Two are hooked directly to TVs and have no problems. The other one is using a very old Pioneer AVR but it also has little or no audio dropout problems.

We hope D* gets this problem resolved, but tonight was a nice break in the 3 to 5 minute occurrences of very brief audio drops. I would be interested if anybody else saw some improvement tonight.

I hope it continues for you! As for us, we still had the usual 3 to 4 audio dropouts per hour while watching (live) USA and HGTV for most of the evening.

Had the same two exact dropouts via Onkyo TX-NR901 (TOSLINK) and Denon AVR-891 (HDMI).

I just checked those two spots without playing the entire recording. Now that I am, server is a HR23-700, client is a HR24-500, AVR is an Onkyo TX-NR901 using TOSLINK for audio.

Two drops both around the 0:08 mark (approx 8min 27sec and 8min42sec), 44min 41sec, 49min 55sec.

Last week's showing of Penn & Teller's Bull**** had four audio drops, at exactly the same spot, on both the east and west coast feeds. This weeks show, no dropouts the entire show on both east and west feeds shows.

And add Encore HD as another channel I'm hearing dropouts on, HR24-500, Onkyo TX-NX901 TOSLINK, Saturday 8/7 about 20:43CDT.
