Could be, but you might want to reproduce your test results because all my breakups were in the first few minutes of Lost (Comcast 6412).
It does seem to be happening only with some
brands of receivers, so it's possible that redvette's Panasonic whatever-it-is receiver is not affected. Somebody earlier stated they had no problems with their SA cable box on WOW, also.
I still think it's a compatibility issue between the transmitting encoder or its setup and the receiving decoder in the particular receivers that we're complaining about. Perhaps these receivers share a common component that chokes on the bitstream from channel 7? It must be that nobody at WXYZ uses one of these receiver types to test their transmissions, or they would have realized that whatever change they made to their system in middle-late November caused this problem for so many of us.
I'm convinced it's a change they
- I've seen it happen during all their programming (and local commercials), at all times of the day, so it's not a network source issue
- There are lots of people here reporting that they had no issue at all with receiving WXYZ-DT prior to Thanksgiving week, and now are having this problem.
- It seems that the really bad dropouts occur at the same times for everybody who experiences them (e.g. the first and last segments of Lost this week). Multipath and other OTA reception issues would not be so uniform across the whole metro Detroit area.
- The signal "strength" meter on my receiver reads a solid 85-90 on channel 41 nearly all the time. This has not changed since before I started having this issue, and it now appears to be no different during periods of frequent drop-outs than it is when I'm not having drop-outs.
- My HD-Tivo hasn't had any software updates around this time frame, so I can't say that the receiver has changed.
Bear in mind that I don't have any technical knowledge about DTV, so it's possible some of these reasons don't apply, but to me they add up.
I can't seem to get through to the engineering dept at channel 7 - mostly because my work schedule doesn't allow me to call during "normal" hours, and they don't acknowledge e-mail. It seems they don't post here either, unlike several other local broadcast professionals.
You may have done so already, but if one of you guys that has already got their ear could explain all this to them, maybe it would give them some clue to solving this. It has gone on far too long already.(edited to add another point and to reiterate my earlier ignorance disclaimer )
