If I were a conspiracy theorist, I'd say KDFW and WFAA called their buddies at KDFI and KXAS and said, "can you guys cut down on your guide listings? You're making us look bad."
No, I don't really believe that, but it's definitely a move in the wrong direction.
Looks like KERA/13 and KDAF/33 are setting the standard now in DFW, still with 3 days of listings. Edit 1:
I rechecked the guides Friday evening. KXAS/5 was down to 24 hours, but KDFI/27 was up to 48. KDFW/4 still at 12 hours. I'm starting to think they lied to Ed Edit 2:
Rechecked again Saturday afternoon. KXAS/5 now up over 3 days! Which suggests that KXAS enters several days at once, then the guide slowly "runs out" until they enter more. Apparently one of the update times is late Friday evening or Saturday morning. KDFI/27 may do something similar, but they seem to have "settled in" at 48 hours. I'll keep watching....
Other stations seem either to update their guides more frequently, or to send data out only up to a limited time in the future. You don't see the guide length jump up and down like KXAS's does.
Rechecked yet again Sunday night. KDFI at about 36 hours again, but KXAS was up to almost 6
days (actually about 6 hours short). It's starting to look like they enter the Mon-Fri schedule on Sunday, and the weekend schedule either late Friday or early Saturday, so Saturday mornings & Sunday & Thursday evenings are the best times to search the guide and schedule upcoming recordings on NBC or Cozi....However,
I'm getting inconsistent results for KXAS on my two Pals. The Dish DTVPal shows everything through mid-Friday, but the CM-7000 Pal only shows about 36 hours. If you go further it's mostly
"no info available," but I do see a program or two filled in
This is only on KXAS; other stations' guides look about the same on the two Pals. Guess I'll just have to check KXAS's guide on the Dish one from now on.Edit:
Did some research on PSIP guides today. There aren't hard-and-fast rules for how often to send guide info, but there are recommendations:
EIT-0 (the 3-hour block including the present time) should be transmitted every .5 second
EIT-1 (the next 3-hour block) should be transmitted every 3 seconds
EIT-2 and up should be transmitted every minute
These recommendations minimize bandwidth used by the guide even if a large amount of data is being sent (as with KXAS). But they mean a receiver may take a full minute to receive more than the next 3-6 hours of listings.
I have no idea whether KXAS follows those recommendations. I suspect they follow the overall spirit, but not the exact timings. I wonder if they transmit the first 36 hours more often, and the really extended listings less often? And I wonder if the CM-7000 Pal cycles through the channels too quickly to download the extended listings?Edited by JHBrandt - 3/4/13 at 8:56pm
