I was being ironic. But actually there is a difference. My individual ability to add a new TV and antenna does not impact on the use of that same spectrum and signal of any other tv viewer. Whereas the growth in individual smartphone usage is the driver and rationale behind the demand from the telcos for more spectrum.

By that analogy, Bell and Rogers should have stopped signing up new internet customers when they claimed to have congestion on their networks. Car makers should also stop making cars when there is traffic congestion.

Context is king, my friend.

And really, on the analogy/congestion thing, given that no broadcaster at all is clamouring for wide scale expansion of OTA in Canada no moratorium is needed at all. They are just doing it to satisfy the demands of the Americans (for whom smileys were invented).

I say FINE, let them have the added spectrum PROVIDED there are ZERO barriers to T-Mobile, ATT, Verizon etc. joining the fray up here. Besides Bell, Rogers and Telus we have zero networks of any note so prices are set by the big three, if just ONE of those big pocketed US companies made it up here we would actually see competition....never gonna happen.

Agreed. The situation in the US is driven by wireless phone company and government greed. The difference there is that OTA is still a thriving business. Bell wants to eliminate OTA completely and their motive is so thinly veiled it can be seen by a blind person.

^^^ Agreed. BTW, read FCC Chairman Tom Wheeler's bio. He's in the Cable TV Hall of Fame, he raised a LOT of money for Obama's campaign. It so obvious what's going on in this and other industries but people are either disinterested or totally numbed by it.

Theoretically it would be possible to phase in the repacked spectrum in Canada's non-border areas, so this could happen sooner up here than down south of the border. Cities like Calgary and Edmonton have huge mobile telecommunications demands yet relatively few OTA stations in comparison to the Vancouver, Toronto, and Southern Ontario border areas. I can imagine a piecemeal repacking happening here in certain parts of Canada.

H.265 capability for new TVs should be mandated soon. The future of the UHF spectrum will decide if we need to use it to put 6 - 720, 4 - 1080 or 2 - 4k stations on each channel.

Hardware availability and Audio improvements too, hopefully

Depending on the speed with which manufacturers can ramp up H.265 chipset production it would not be long for USB and set top box products to take to market. It was inevitable that ATSC's MPEG-2 would become obsolescent, but skipping H.264 (MPEG-4) for H.265 would make for a whole new hardware market, and of course a selling point for new OEM HDTVs.

I would presume that a similar technological jump in OTA audio modulation would also happen, with common broadcast of DTS, TruHD, 7.2, etc. etc. formats via OTA.

Audio formats may make a move to Dolby Digital Plus (AKA Enhanced AC-3, DD+, E-AC-3 or EC-3.) It has the advantage of allowing widely variable bit rates. Netflix already uses it with compatible devices such as the Chromecast. It can have bit rates from 32Kbps to 6.144 Mbps and from 1 to 15 channels. It's suitable for anything from a low bit rate monaural voice stream to high definition surround movie sound with multiple audio programs.

Don't confuse compression with encoding. H.264 and H.265 are compression algorithms. Things like DTS, Dolby Digital and TrueHD are audio encoding schemes. They are completely independent, though better compression often provides enough capacity to allow better audio formats to be included.

That will require a radical change in thinking in organization such as IC, the CRTC and most Canadian broadcasters. Rather than have widely spaced transmitters with haphazard coverage they might need to consider sharing towers and providing uniform OTA coverage to Canadians. How un-Canadian is that? It would almost be like the UK where 99% of OTA viewers can get every network OTA. It could lead to a situation where 90% of Canadians could once again get our publicly funded, national TV network, AKA the CBC. It might even lead to an unthinkable situation where some company launches a service like FreeSat Canada and TV viewers would not need to pay ridiculous fees to get basic TV service.

I was definitely not confusing video compression schemes with audio formats, but people should be aware of those portions of a digital TV signal anyways.

Another opportunity with this technology upgrade is to support 16-bit colour depth so that as material becomes available OTA will be ready: 10 bit color depth. The higher the bits of colour depth, the more realistic the eye perceives the image.

Freesat is not on topic for the OTA Forum. It is discussed elsewhere at our site.

Those are ALL audio compression algorithms (yes even "Lossless" TrueHD)....PCM and DSD (e.g. SACD's) are the usual uncompressed audio encoding "formats" used in the original recordings:

Yep, after all this time and after all the subimitted comments in favour of OTA the authorities are still referring to OTAers as some sort of tiny fringe group.
