HD channels - Jagged and stairsteped edges

Noticed in the past week or so that several (but not all) 1080i HD channels appear as if they were poorly upconverted SD channels, are missing scan lines, or the interlaced fields are sent in reverse order. Very obvious on channel logos which appear jaggy or and have dark lines through them, but also quite easy to spot as a stair step pattern on any diagnal line in the picture.

Sample images can be found here: It appears this is a nation wide phenomena (I'm in zip 75077, many others in this link are in the northeast):

Another person in PA apperently reported this in the programming forum with no followup:

Channels that are affected that I have observed (all 1080i HD):

Animal Planet

BBC America

Science Channel

Discovery Channel

There may be others that I don't regularly watch or do not recieve.

Thank you!

I've noticed the exact same thing for about the last 2 weeks. I Googled it and came across this post & several others regarding the same issue.

I'd call it "stair-stepping" or "aliasing"; perhaps a problem with improper interlacing/upscaling. It's most noticeable with white text on a dark background, and especially on the little channel logo in the lower-right corner of the screen.

As others have mentoned, it appears to only occur on 1080i TV's; the same channels look fine on my 720p TV.

One other channel to add to the list: DestinationAmerica HD (channel 668 on my system).

It's amazing that Verizon hasn't addressed (or even aknowledged) this problem. Heaven knows we pay enough for FiOS every month to have access to alleged "HD" channels.

Come on Verizon - get it together!

As of today (7/9/14), this issue seems to be resolved. Verizon must have fixed it on their end.

This problem is still present on long island (VHO5) and it's still just as annoying.

I am seeing this exact issue on BBCA and Discovery hd in northern NJ, zip 07079. Glad I searched, I just got VMS/quantum and thought it was a hardware issue, which would have put me over the edge to return quantum until they get more of the bugs worked out. Are others still seeing the aliasing as of today, 7/18? Thanks!

The problem comes and goes on the same set of channels. I noticed the jaggies today on Discovery and yesterday on BBC America. Maybe fixing one channel breaks another?

This problem does come and go but it is always present on at least 2 of 5 channels for me. The Verizon support people who work the DSL reports forums tried to tell me it is my equipment, even after I told them it is the same on two different set top boxes and my HTPC/HDHomeRun Prime.

Today I have the problem on Animal Planet, Science, Discovery, TLC but Travel is fine. 4 of 5 bad. Not a good day.

This has gone on so long I am seriously considering going back to Comcast after 4+ years with VZ.
