Perhaps the piece located at the station ?
Please help me identify signal glitch cause
I recently made several posts regarding occasional picture break-up and pixilation, which prompted me to replace my external eSATA hard drive with a 2TB SSD (also eSATA). The jury is still out WRT whether this has completely resolved the pixelation issue.
However, over the past several weeks I have been experiencing a different signal quality issue on my local NBC station. It only occurs several times a week. The TV screen completely goes blank for a second or two and repeats the screen blanking several times before returning to normal. The NBC signal will then return to being stable for the rest of the evening. I have attached a link to a 30-second video on Dropbox of an occurrence of this strange issue that occurred last night. I would appreciate it if someone would view the video and suggest what might be happening.
Fortunately, the issue happened when I tuned into last night's live broadcast of Saturday Night Live on my bedroom HR24 at the same time the program was recording on the downstairs HR54. After experiencing the glitch on the HR24's live feed, I played the recording from the HR54, and the glitch was in the recording at the same spot as well. This seems like it rules out the DVR hardware as the root cause. So, what is the opinion--is it likely the actual local NBC signal, or could it be the LNB?
And suggestions would be appreciated.

Edit: Let me add that I have only seen this on the local NBC station, no other channels.

It can't be DirecTV's fault if it also affects their off-air signal. DirecTV has nothing to do with signal.
I reported my latest experiences to the station engineer yesterday emphasizing that the same glitch occurred on both the DTV feed and the OTA signal, and am waiting for a response.It can't be DirecTV's fault if it also affects their off-air signal. DirecTV has nothing to do with signal.
It is still possible that something about how DIRECTV's LRF and the AM21/HRxx are handling the stream is the problem.For the Thursday incidents, I verified that the picture dropouts occurred at the same time on the OTA broadcast, which I was also recording. Needless to say, whatever actions DTV took did not resolve the issue.
Eight years ago there was a thread about the HR34 gagging on NBC LiL content and I'm wondering if it has come back to roost.
James established that DIRECTV has an LRF in Tacoma so that would preclude having equipment at the station.Perhaps the piece located at the station ?
That depends on where your evidence of the OTA glitch comes from. If, for example, DIRECTV was using AM21s (or something functionally identical) at the LRF, that could be the problem.It can't be DirecTV's fault if it also affects their off-air signal. DirecTV has nothing to do with signal.
Jerry said it's in the OTA stream, that means it's not Directv's fault. It's that simple. There could be other issues on Directv's end but that has NOTHING to do with the glitch Jerry is seeing OTA.It is still possible that something about how DIRECTV's LRF and the AM21/HRxx are handling the stream is the problem.

Are you using DIRECTV's AM21 to receive and record the signal? If not, then I'll agree with the logic and say that there isn't anything that DIRECTV can do to affect a non-DIRECTV tuner. But if you are using an AM21 then perhaps by some strange coincidence the station's glitch is affecting reception by the equipment at the LRF and at home based AM21s (but somehow only DIRECTV receivers).
The coincidental reception issue of two completely different receivers in different locations showing itself as the same glitch at the same moment not being a transmission issue is a stretch. I'd still target the station. But if one wants to completely 100% eliminate DIRECTV the glitch would need to be seen with no DIRECTV equipment in the path.
If only it were that simple.Jerry said it's in the OTA stream, that means it's not Directv's fault. It's that simple.
Unless Jerry has a third party DVR that he hasn't mentioned, it appears that a (or possibly more) DIRECTV DVR(s) is (are) making these recordings.
If the NBC stream contains something that DIRECTV DVRs don't like (as has been documented to happen previously), it will manifest in a blip in both recordings at the same point in the program (as opposed to the same time in the recording) and look just like a OTA problem.
If such a problem hadn't happened before, a transmission issue would be a confident conclusion.
To clarify, I am recording on my HR54 both the satellite signal and the OTA signal from a connected AM21. I have seen the picture dropout issue on my bedroom HR24 as well.
I would connect a TV to the antenna only and see if the problem is still thereTo clarify, I am recording on my HR54 both the satellite signal and the OTA signal from a connected AM21. I have seen the picture dropout issue on my bedroom HR24 as well.
The OTA signal is split and routed to directly to the TV as well, so I could watch the NBC broadcast directly without the DVR or AM21 in the signal path. However, since the picture dropout issue doesn't happen that frequently, that would mean watching a lot of live TV without being able to skip over commercials. Sorry, but I don't consider the picture issue as being important enough that I would want to watch that much live TV.I would connect a TV to the antenna only and see if the problem is still there
If your TV have USB port, I would try add PVR function to it by connecting USB drive/flash stick. All EU models works that way.
If the glitch is occurring at the same moment in the source programming the issue still seems to be at the source. Station to LRF to uplink to satellite to dish to receiver path sees glitch at the same point in source programming as station to user antenna to AM21 to receiver? DIRECTV isn't using AM21s at the LRF to convert OTA signals to feeds for the satellite retransmission. The difference is as good as stating that the station is being received on two different types of tuners.
The same moment in programming is an important note. If there was some in home glitch (electrical issue, LNB issue, AM21 issue) that through some weirdness only affected the recording of this one station the glitch would occur at the same moment in time, not the same moment in programming. Such an in home glitch should appear in the OTA recording before it appears in the via satellite recording ... not synchronized to the moment in programming.
The signs are pointing at the station.

No US market models work that way and there isn't point much importing of EuropeanTVs given the frequency differences (50Hz vs 60Hz) and the fact that most of the EU uses DVB-T rather than DTV.If your TV have USB port, I would try add PVR function to it by connecting USB drive/flash stick. All EU models works that way.
This is the point that I've been trying to make in several posts. It is why I introduced the idea of wall clock time versus program run time.The same moment in programming is an important note. If there was some in home glitch (electrical issue, LNB issue, AM21 issue) that through some weirdness only affected the recording of this one station the glitch would occur at the same moment in time, not the same moment in programming.

There are three possible DIRECTV causes for a program run time issue. Broadcast signal bobbling is one, a NBC network reception lost by the station is another (though I'd assume that the engineer would know about these) and the third is DIRECTV equipment choking on the stream. I think most of us are willing to pass on the idea that NBC's uplink is bad. Choking on an NBC stream has a precedent so it would be unsound to summarily dismiss it.
If someone with a non-DIRECTV device could record some of the same NBC programs, that would help pinpoint the problem.
No response from the NBC station engineer after my report last week, and the problem persists. There was a nasty picture drop-out during this morning's Meet the Press broadcast. I guess no one really cares about signal quality.
REASON: They are sending "FREE" over the air (both ways) --Even though we "PAY" for RE- transmission on D*TV equipment -so, you are correct NO ONE CARES as the check is sent either wayNo response from the NBC station engineer after my report last week, and the problem persists.

Have you tried parallel recording any of KING5's subchannels? This could narrow the scope to a bad multiplex/demux (station issue) and almost entirely eliminate a signal interruptionThere was a nasty picture drop-out during this morning's Meet the Press broadcast.
I have no way of doing this that I know of.Have you tried parallel recording any of KING5's subchannels? This could narrow the scope to a bad multiplex/demux (station issue) and almost entirely eliminate a signal interruption
