The EIT listings are back, for what it's worth. Co-owned WRGB and WCWN are best at 3 days of guides. The rest have from a few hours to a day. Pitiful.

Since several stations' listings disappeared at once, my guess is that they use the same guide service and it failed. But I don't know anything about where that information comes from. Anyone associated with a station care to fill us in?

Many of the local stations use DecisionMark to format the guide information for the PSIP generator which provides, among other critical things, the guide information. Recently DecisionMark made a change to the server from which the information is downloaded, causing the difficulty. As observed, this has been resolved now.

FYI, the number of days that a given station publishes the guide information has to do with the available bandwidth. There is a trade off between the allocation of bits to the program stream data and how much is left for the guide. Typically a station might provide more days of advance guide information if they have the available the bits to do so, so you may see anything between 1 to 3 days depending on the number of program streams, audio channels, etc. that a station is carrying.

I noticed that CBS on 45-3 is now in 720p HD instead of the former SD, along with WCWN in 1080i, and GritTV in 480i (2 HD and 1 SD subchannel). Thanks, WRGB EngDept for the better picture on CBS on 45-3! I'm in a fringe area, and 6 hasn't been as reliable for me lately as it used to be, so when I have to switch to 45-3 to get CBS, it's good to have a better picture (I get 45 on both RF 24 and 43).

I have to admit I'm impressed by what they can do with a low bit rate. Comparing WRGB on 6.1 with 45.3 on a 1280x720 monitor, I really don't see any difference. I might on a higher res monitor. Of course a shot without much movement doesn't need a high bit rate to look good. I'll have to check again on something like CSI's opening credits.

With golf on WRGB and baseball on WCWN TSReader Lite showed these bit rates:

Code:
Name     Chan    Mbps
---------------------
WRGB-HD   6.1   15.72
this TV   6.2    2.28

WCWN-HD  45.1   11.10
Grit TV  45.2    1.20
WRGB     45.3    5.27
