Global's Transition PSIP Issues Explained - see Post #24

I am currently seeing what I can only describe as digital "snow" on CICT-DT (Global) Calgary. It looks like analog snow but everything is on a green background. Is it just me?
BTW, Global on Channel 2 analog is just fine.

UPDATE: The station (on all channels) was briefly frozen on an image from an earlier commercial.
No sound on Channel 41. But on Channel 2 and on Shaw Cable 7 (both analog) the sound was as per the usual programming.

UPDATE 2: Everything back to normal, except that the PSIP information for Channel 41 is different. It now says CICT-HD (was CICT-DT) and strangely the signal level seems a little better than before.

Noticed this in CIII Channel 41 Toronto's PSIP (EIT) today:

Channel 1
Service Name: CIII-HD
Provider Name:
Transport Stream ID: 17321 (0x43a9)

---------------------------------------------
Starts: 2011-09-02 19:30:00
Length: 97:30:00
EIT Source: n/a
Name: DTV Program
Description: DTV Program
I think this means we'll see over 4 days of "DTV Program" instead of nothing form program information, then maybe some real guide data?? :)

I'm excited to hear that proper PSIP data is coming to Global stations! I've been waiting for this for a long time now...

Cool. i would really like to test but even if i was getting a fair to good analog Global Ottawa signal, now i can`t even scan it with my medium VHF antenna in the attic which is connected to a preamp after 20-25 feet. Model is Delhi VIPO302sr pointed at Camp Fortune, VHF Lo gain of 4.

Will Global Ottawa apply for a higher ERP on a temporary basis under the TO status ? That can help raising the power more quickly while the formal application is being approved. I am guessing Paris might be in the same boat.

Is there a schedule for when Global Montreal in Sherbrooke on 11.1 will be getting PSIP data? As it stands, it is the only one of my stations without a guide (or callsign..but there is accurate time), which kind of deters me from watching it - usually I end up switching to the American networks.

Still, it's much better to have it in HD than analog...and it's also the only English Canadian station I receive at my cottage, so I have to thank the people at Shaw for actually converting to digital, unlike the CBC.

i can confirm sherbooke i still having the problem as of today the transport stream id is different in the PAT and TVCT is this because the transmitter is really CKMI-DT2?

Thanks for checking in Dan.

During a recent trip I scanned Quebec City, Fredericton, and Charlottetown. All were mismatched and the Quebec City channel wouldn't scan on my Windows 7 laptop nor the Sony TV where I was staying. I was able to watch Quebec city after manually adding it to the Sony TV. I haven't tried watching Charlottetown or Fredericton on Windows 7.

Thanks for looking into it Dan. Appreciate it.

If I remember right, the MGT for CKMI-2 specified a lot of ETTs/EITs, but none were being sent out. I would take this to mean that the guide data system is partially set up - which makes me hopeful for guide data.

Trip,

If/when the PSIP is updated, I'll send you a new copy of the TsReader data.

Note that before I left Sunday afternoon (02/10/11) Global's breakups at my cottage were much less severe than usual. To be fair, though, I noticed the transmitter was surrounded in a huge rain cloud, so that may have had something to do with it. Personally, I'm hoping that something was done with the PSIP that helped my TV hold the lock better than it usually does.

It was probably the weather, though.
