Pace MPEG-4 set top boxes (TDC787X) - Page 3

post #61 of 387
Armstrong Cable. I do know that 2 of the shows that were causing audio issues were Greys Anatomy and Oprah... as I had said before unsure of what they broadcast in. I will update more later. I have taken the box out and am waiting for the update before reinstalling. I'm currently using the 775 .......Im anxiously awaiting this one though because it is an outsatnding looking box and still has all the great pace features..
post #62 of 387
I never checked audio though coax output.........thats an idea..... I just know it only showed up on HD with every 787x I had in my possesion....... SD version of channel never had issue. Im sure it will get fixed soon......just a small glitch
post #63 of 387
I know Grey's is usually broadcast in 1280x720p / 5.1 Ch DD Audio.

The user manual for the TDC776D is now available here. Ditto for the TDC787X and DC700X.

FYI,

I updated the first post with links to a new MPEG-4 capable box (Apache).

Is anyone else here experiencing audio issues with either Oprah or Grey's Anatomy?

I've tried 2 different TDC787X boxes from Armstrong with both producing the same results.

14 SD channels severly break up in both video and audio to the point of being unwatchabe. HD channels are fine fortunately

I have a DC757X and a DCH3416 that work perfectly. I've tried moving the box to other locations in the house without improvement.

I have 2 feeds from the pole. I've connected the box to a tap on each feed.

HDMI, component and svideo all produce the same results.

Armstrong said they'll get back to me in 48hrs.

Linden, please help!

I'm afraid I don't have an immediate answer. I do have some questions:
  1. Is it possible for you to do a recording of the breakup?
  2. Can you please post the diagnostics inband and OOB (out of band) page details?
  3. Can you please list the SD channels you are having problems with?

I would think the tiling is caused by a line issue from your cable company. I would have them come out & check. I've seen tiling caused by a bad fitting that was put on by an installer. A piece of material was touching the "stinger" & once that was cleared... the tiling went away.

Since these boxes have MPEG-4, will HD look better than the Tahoe?

I believe that there are two other boxes in the residence that don't experience problems with the same signal, so I'm not sure this is being caused by signal quality (the diags will hopefully help us discover the issue).

Linden,

Here's Pics of the diags screens. If someone has a better way than this, please let me know. I was on Ch 29 which is one of the tiling channels.

If its not too painful, I'd like the inband information when you're on an HD channel that doesn't macroblock. The dashboard is reporting lots of errors in the stream.

It also would be useful if you could obtain the same inband diags info on the DC757X.

Finally, have you tried swapping to the second tuner to see if the macroblocking occurs with both tuners?

BTW, the screen caps are fine. Some users write the values down and post the info as text. Its your call whichever is easiest for you (its easier for me to read the text and save it for future reference).

MPEG-4 is not automatically better than MPEG-2. It depends on how the content is encoded, bit rates etc. Its true that its possible (likely) for MPEG-4 HD content to look better than the equivalent MPEG-2 stream at the same or lower bit rates, but its highly site specific.

Right now, most cable providers are not broadcasting lots of MPEG-4 content so I wouldn't expect a significantly better viewing experience until MPEG-4 content becomes more common place.

There are a number of threads on AVS comparing/contrasting MPEG-2 and MPEG_4 with the same content. You may want to review those threads for more comparison details.

Armstrong came out over the weekend to troubleshoot the box. The tech admitted that they are having problems with this box. The levels that the box is reporting does not match the test equipment or the other Pace box. Most of the reported issues have been audio related according to the tech.

My latest problem is that I cannot get DD5.1 over HDMI. It always reverts to PCM. I've reset the box to the defaults and power-cycled the AVR. I thought this was working before, but not sure. I was playing with a dual monitor setup and I am wondering if the box somehow detected that the monitor does not have DD5.1 capability.

Linden - Is there a way to regain this functionality?

I'm leaving it unplugged for the night.

Each time you plug a new HDMI device in, it should detect the monitor or receivers capabilities. Please go to the Interface status page (21) in diagnostics, then select HDMI. Let us know what the supported audio formats are on that page.

As reported on the Pace CableCARD STBs thread its not likely to match the level reported by test equipment. The diagnostic information may be up to +/4db from the actual signal level and this is true for all Pace set tops. This value is only a rough gauge as to the actual signal level. What signal level did the tech find?
post #80 of 387
I did not take note of the specific reading from the tech, but he said that the signal to the box was excellent. He couldn't understand why their was such a discrepency between the 2 Pace boxes in the house.

I left the box unplugged overnight and today DD works again. I even tried changing from Auto to pass through, but the box continued to pass only PCM yesterday.

The tiling has stopped, but the box continues to get poor reading, but better than last week.

We have some follow up questions.

1. Does the macroblocking occur when you are watching it live, or just when its time shifted (or pre-recorded)?

2. Is there audio breakup when the video macroblocking takes place?

3. Can you record one of the problematic channels and report the following:

A. Post a screen cap or the text of the content listing diagnostics page (25) for that recording. In particular, we're interested in the number of overflows in the recording.

B. Can you fast forward or rewind through the problematic area (i.e. macroblocking portion).
post #82 of 387
Linden,

I'm heading out of town for a few days. You can see from the youtube video that audio is breaking up as well as video. This was occurring on live TV.

I have a Slingbox attached to the Pace box so I'll be watching while I'm out of town. I'll keep you posted if it starts acting up again.
post #83 of 387
Sorry I haven't gotten back to you before now. I didn't tell you that my IN Band short term errors were all over the place. This was true on every Aspen I tried at my house and the office. When I put any other Pace in its place I had virtually no Short term errors.

Do you know what firmware release you are running?

I just updated the Aspen Release notes thread with the latest release information. This release should address the outstanding audio issues that have been reported (although I don't think its going to solve your problem).

That setting is within the standard on-screen "Cable Box setup" choice - just a toggle between current time or current channel. Press the "menu" button on your remote to pull up the various choices then look for cable box setup (or something similar).

I just received this box (TDC787X Aspen) from my cable company. I was using it last night, and everything was fine for the first couple of hours, but now the box is unresponsive to the remote control. I was issued a universal remote from the cable company and that is the one that I know was working and is now not working. I also have a logitech harmony 550 and that doesn't work either. Finally, I have another of the cable company universal remotes that worked my previous standard def. dvr from pace and it does not work either. This morning I was able to get one of the cable company remotes to bring up the guide and then I navigated down one line on the guide and then again it would not work. I am pretty sure it is the box after that experience. I was wondering if any other users have had this issue, and if there was something I can do to resolve it. Also, does anyone know if the harmony remotes will control this box or should I put it in as a different make or model? Thanks
post #88 of 387
The problem with the remote not working only happens when the aspen is connected to the tv with hdmi. I have a samsung ln46a550. Is there a setting on the box or tv that is causing this?
post #89 of 387
One more update. Basically, the remote doesn't work if the tv is on, but if the tv is off, the remote works and the channels change on the box. I have now tried connecting the aspen to my sammy using all of the available outputs (coax, composite, component, and hdmi) and it doesn't matter how it is connected to the tv.

Some LCDs and Plasmas generate interference that will prevent the remote from working. To work around this problem, you can either move the Aspen box further away from the display or you can get an IR extender from your cable provider, then disable the front panel IR receiver in Aspen via Pace User Settings.

If you decide on option #2, please verify that the option to disable the front panel is in the firmware release you are using (it may not be present in older firmware revisions).
