I just did a rescan and CHEK is up at what looks to be a lower power level, and KBCB digital and analogue is still down. Everything else is up.

I noticed yesterday with the PSIP changes at CIVT-DT that they are not remapping to 32.1 anymore.

Its now staying on 33.1 and this decision is similar to the recent decision made by CTV in Toronto (CFTO-DT) not to remap anymore.

There is an extra problem with channel 33 as well.

Previously I think we all assumed that KWPX-DT would stay on channel 32 post analogue shut off in the states. It now appears that they have elected to revert back to their analogue assignment - Channel 33 with 179 kW ERP.

I think that this would mean that CIVT cannot raise the power on 33 ever. Maybe the best bet would be switching with CKVU.

Another long term solutions may be switching back to 32 after the analogue shutdown here :rolleyes: o

One more option I thought of would be to switch assignments with CIVI-2 (analogue 17), a station which they own now. Looking in the Industry Canada assignment list it looks like a digitial assignment for CIVI-2 has not been made. Does anyone know the digital assignment for CIVI-2?

I think it was always the plan to revert back to the analogue channel after analogue shutdown. Isn't that what re-mapping is all about? CIVT will go back to channel 32 and KWPX-DT will go to 33.

I must disagree with your comments about CIVT interfering with KWPX-DT after everyone is digital. One of the reasons for switching over to digital is a greater tolerance for co-channel interference. As I mentioned in another thread, for an analogue signal not to show any interference, the unwanted signal must be at least -53 dB (1/446 or 0.22%) compared to the signal being received. This is why CIVT is on flea power as I calculated earlier in this thread: http://www.digitalhome.ca/forum/showthread.php?t=25774&page=4#51

I don't know the robustness of digital for co-channel interference, but it is far better than analogue. Also, I believe there is about a 30% margin for error correction in the MPEG signal. KWPX-DT is transmitting on channel 32, the same as CIVT analogue but I would bet that no one receiving it has any problems with interference from CIVT.

The change was in fact from "CIVTHD" to "CIVT-HD".And now they've changed it to CIVT-DT.

in Bellingham. The analog reception on 32 is the same--poor, compared to 2,6,8, and 10...and still no digital reception.

They're just tinkering with getting their PSIP data correct, so its not about signal coverage unfortunately.

I did a channel scan at 2pm and CBUT-DT was no longer remapping to 2.1 but showed up on 58.8, so I checked for guide and program info but there is zero PSIP data coming.

Seems like CIVT flipped back to 32-1.

I scanned again 3 hours after the previous post and all was back to normal with CBUT-DT's PSIP data.

Marc,
Each of the last three nights the start of the National at 10:00pm has had audio problems. It lasted about 10 minutes on Tuesday night.

The audio comes in double. One audio stream is in sync with the video, but another audio stream leads the video by about 1 - 2 seconds.

Also I notice that the audio is coming in as 5.1 while this is occurring.
Is the audio on CBUT set to 5.1 at all times now?

I noticed yesterday's episode of Simpsons was encoded in DD. I didn't put my ear to the surrounds, but I can say the Left, Center and Right all and audio.

ardsa,

I'm listening to Tuesday's National right now. I only hear a single audio track. This is a downconverted VHS tape of the Vancouver HD (ATSC) signal as it leaves the Broadcast Centre in Toronto.

I will address the audio coding question in the main CBC thread.

Thanks Marc,
It has happened 3 times now and is quite annoying.
I don't have a 5.1 setup. I have my reciever set to mix the 5.1 stream to 2.0. Perhaps the rear or centre channels have the audio sync problem.

I will try to make a recording if I see (hear) it happening again.

Make sure your receiver is set to only pass the first audio stream. We transmit 2 streams. One is the regular 5.1/2.0 primary audio. The other is a 2.0 described video track. I have an analog receiver that allows me to mix main and DV audio. (I don't know why...)

When a show has DV, you will hear narration on the second stream. At other times we try to put program sound on those tracks. Sometimes the DV track is silent. I would expect the DV track in time with the main sound, but they could be out a bit.

Some of our DV shows: Rumours, Intelligence, Jozi H, Doodlebops.

I would expect the DV track in time with the main sound, but they could be out a bit.I have never received a DV track on my digital tuner. I don't even think it has the option for playing an optional audio stream.

I certaintly have not noticed this problem when I watch Intellegence. The problem seems related to the National for me. Last night the problem only lasted for about 2 minutes right at the start.

Also, last time I spoke to BCTV, I was told they just received the licence (it is either the work order from the Global HQ, or they were told by HQ to tell that they just recived licence from CRTC if asked) and are finaly working on the Mt Seymour transmiter and also are upgrading the studio equipment to HD right now.
They think signal will be on air by the summer 2007.

they just received the licence (it is either the work order from the Global HQ, or they were told by HQ to tell that they just recived licence from CRTC if asked)I like how you put that... :D Everything is such a darned mystery with Global HQ, especially given their presentation to the recent CRTC hearings. I wish the local techs were free to drop in here and chat.

After numerous email inquiries to Global regarding their plans for OTA in Vancouver, I received this reply from their "Viewer Relations" dept....it's obviously written by a pr person, and doesn't provide much in terms of their future plans or schedule for OTA implementation...Hello and thank you for your email. Please accept our sincerest apology for not getting back to you in a more timely manner.

At CanWest we respect our viewers and take great steps to ensure quality programming. As responsible broadcasters, we are sensitive to the concerns of our viewing community. We value our audience, and we appreciate regular feedback in order to maintain high standards. We appreciate and respect the fact that you have an interest in our programming and that you were concerned enough to bring it to our attention.

At this point in time, we do not have over-the-air High Definition transmission available. Unless Global has access to the HD material prior to telecast, or we are able to receive and air the show at the same time the US networks air in HD (simulcast), then we simply do not have the HD material available to bring to our viewers. If it is airing outside of simulcast (and unless we have a tape copy of it in HD) we will air the SD version of programs.
At this time we are working with the distributors to get more material delivered in HD. Our HD content will increase over the coming months as more new material becomes available.

In Public Notice CRTC 2003-61 (The regulatory framework for the distribution of digital television signals), the Commission considered that the definition of HD, for purposes of the regulatory framework, would encompass both the 720p and 1080i formats.

Global Television prides itself in continuing to offer our viewers the highest possible HD quality. To that end, we are the only broadcaster to provide the two major Canadian distribution undertakings with the HD format of their choice: Rogers is fed with 1080i and Express Vu with 720p. We have also taken great care to ensure that the original HD audio configuration (5.1 surround or 2.0 stereo) is “passed through” our plant with no degradation or alteration. Our attention to detail and high quality have been praised by Rogers, Express Vu as well as our viewers.

We understand your frustration and agree that you should be getting the best HD quality that is available to you. As stated above, our role as a broadcaster is to provide the distributor with the HD signal and the distributor is required to pass it on to their customer without any degradation. We are confident that the highest quality HD signal is leaving our facility.

We hope this helps explain the situation from the broadcaster’s perspective.

Sincerely
~Viewer Relations
Global and CH Television

Thanks for that dawydiak, and I agree that this is standard PR boilerplate. The respondent just didn't get what you meant by OTA. :mad:

As someone here on DHC once said, CanWest Global HQ seems to wish that HD and Digital OTA would just go away. Too bad because I know there are techs with that company who would love to get going with high end gear.

Ran a scan this afternoon and for the 1st time found 32.1 and 33.2. A pixelated picture popped off and on for a brief second or two. Signal strength is 38...maxed at 51 while I was checking. Basically no picture to report. Wondering if they recently increased their signal output any for my tv to sense their channel?

Also the tv assigned the designation CITV-DT to 32.1.

To be continued...
