ExDilbert Never mind that broadcasters aren't interested, the CRTC will not allow it. Existing OTA services are not allowed to share channels, they must be on their own channel. New services are allowed on sub-channels but broadcasters are more interested in shutting down towers to save costs, not expanding OTA services to generate revenue. Any new services are going on cable because collecting fees from subscribers generates more income than OTA.

rob50312 Robert Canadian sub channels not likely to happen.With TV service providers and broadcasters owned by the same groups ,there is no profit in providing OTA.I suspect you will lose those analog signals you now have too.Your politicians expect you to pay to watch Canadian stations.

Robert C Wicks I live in a small Northern Ontario area that used to have a decent number of analog TV channels. We still have two analog channels and one digital. We used to have more but they disappeared? when they were switched to Digital. I would like them to use the Sub channels so we could regain the channels we lost like CBC English and French, TVO etc. The channels I recieve from USA added major networks to their subchannels in my area. Canada should do the same.

For mandatory carriage and/or simsubs the CRTC has said they would consider it on a case by case basis. There three categories of BDU carriage (with various sub options):
  • Mandatory Carriage
  • Optional Carriage
  • Prohibited Carriage
Only in that last case could I see the "concerns of Pelmorex and others" not being applicable. In the other two cases, the channel could be competing with other cable channels. Having said that, I am not convinced that this competition is a bad thing.

Really this bit appears to be nothing more than a sop to the objections of Pelmorex.
If BDUs were prohibited from carrying the sub-channel, this would be true, but it is unlikely to be the case. If it was, I am not sure if a profitable business case could be made for Canadian broadcasters to have a sub-channel that isn't carried by any BDUs.

The Commission shares the concerns of Pelmorex and others in this regard, and will therefore be predisposed to license new and innovative services, in preference to those that would merely duplicate the services of existing off-air, specialty or pay television undertakings.

The CBC is, but in many cases the SRC isn't, so they will continue to use their VHF-HI antenna.

While true, in many if not most markets in question, the CBC will be sharing a UHF antenna with other stations so they will need to do these anyway.

True.

The other factor that prevents the CBC from doing this is hockey. For most programming, you can get away with reducing the bandwidth and not see a huge difference in PQ. The exception is scenes with fast motion and since hockey is a big revenue generator for the CBC and it is one of the fastest moving sports they need all the bandwidth they can get.

As discussed previously in other threads, even if the CRTC permitted it, not only is there little incentive for the networks to do it, there is actually a large disincentive. As cable only channels the broadcasters currently receive money from subscribers for them (even the ones on basic service). Put them on a sub-channel and the broadcaster would likely loose this funding.

Obed Thanks Stampeder, good to know. Awesome forum btw!

By the look of things HD picture quality should be superb for the Canadian stations for a long time to come and far superior to many of the US feeds leaking over the border. Should keep a few folks happy!

stampeder Obed, just to make sure you are aware of the technical issues that cause many OTAers to dislike sub-channels, please be sure to read Post #15 in the OTA FAQ, which explains that as sub-channels are added, the picture quality of the main channel and any other sub-channels on it are compromised. While you may see good reasons for sub-channels, many of us despise them.

From what I understand, and I could be wrong, please correct me if I am, but:

1. The CBC seems to be trying to move to UHF in advance of a roll out of Mobile DTV.

2. I'm under the impression that single-channel antennas are cheaper than broadband antennas.

3. I've been led to believe that combining gear is a pain compared to having a single transmitter hooked to a single antenna.

4. Transmitting only one signal instead of two reduces the power bill, in addition to only requiring one transmitter.

To me, it seems like there could certainly be savings in providing SRC by subchannel in places where the Francophone population is small. The down side in my mind is that it eliminates redundancy; in Toronto, for instance, if the gear for CBLT fails, the CBC could theoretically put the programming on CBLFT 25-2 while it's down.

downbeat Anti-CRTC rants do not belong here.
There's an existing thread for that:

ScaryBob The CRTC has stated that they will only be interested in new, innovative services on subchannels. For example, if SunTV had applied to air a new, all news service as a sub-channel for SunTV (prior to the CAT2 application), it would be looked upon favorably. OTOH, if the CBC wants to combine their existing English and French analog services on a single digital channel, that would not.

El Gran Chico I'm not sure why we are still discussing this topic. The CRTC has clearly indicated that ideas DHC members have proposed won't be permitted (even though many of the ideas are good! ) and the broadcasters have shown no interest in multicasting that the CRTC will allow (multiple existing OTA channels from single transmitter). My guess on the latter is that the suits that run the broadcast empires and could make this happen have no clue of the opportunities DTV provides, like subchannels.
