DTV question [minor]
I wrote back, and he replied to that. Here's what he said, in part:
Nothing changed on our end. However it is not unheard of for set-top-boxes to need to reload the PSIP tables for a channel once in a while. Forcing a rescan forces the tables to reload. Eventually they will usually reload on their own which is probably what happened in your case. (I had done nothing to my DTV box this whole time.) So does anyone know if this is correct? Now there's another station (one of the big networks, not a local independent) that's missing its program info. Is it possible that my DTV box would selectively omit this information for just one or a few stations? Every other station shows this info for me, with the exceptions noted above. It might be true. I note that the information supplied, and even the call letters (!!!) of particular channels, can change from day to day on my Vizio, even though I have done nothing. |
DTV question [minor]
So one of my local TV stations seemingly stopped sending program
information data--you know, the text that says what's on, what's going to be on, and explaining in more detail what's on. Landing on that channel, display simply showed "- No program information -". (BTW, this seems to be the default for all of the minor little public TV stations around here, not including the big PBS stations which are diligent about supplying this information.) OK, no big deal, but slightly annoying, so I fired off an email to the station, alerting them to this situation and asking them if this was due to an omission at their end. (I confess I really don't know what that information is called, or how it gets supplied at their end. All I know is that it is somehow transmitted as part of the DTV datastream.) Well, a day or two later, the program information started appearing for that station. I figured it *might* have been on account of my email--big slaps on the back for me as an Alert Citizen!--but since they hadn't replied, I had no way of knowing. Then a couple days after that I got a reply back. The station's operations manager wrote and told me that they (the station) was supplying that information, and therefore if I wasn't seeing it, it was probably due to a problem at my end. He suggested doing a complete rescan (not an "update scan") on my DTV box. I wrote back, and he replied to that. Here's what he said, in part: Nothing changed on our end.

However, you can identify the culprit by simply checking for data presence on a different TV set (or at a local store). If none of the TV's see data from this station, then it's their problem. If only your TV lacks data, it's your problem. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

IME DVB-T STBs seem particularly prone to mains borne noise and spikes corrupting the various bits of NVR data, you could try a mains conditioning socket strip to clean up the supply or run it through a UPS - handy for power outages that would mess up recordings on a PVR, otherwise doing the occasional re-scan is not such a big deal. |

I ask because after doing a rescan, *another* channel still shows no program information, so obviously the scan did nothing to correct that. I still have no idea if the problem is at their end or my end, but the scan didn't help. Does someone here *actually know* how this information is handled, propagated, etc? Various DVB-T faults get discussed on uk.tech.digital-tv so you could try asking there. A search of the newsgroup list on the server I connect to only found uk, Aus & ru digital TV newsgroups. |
