There are many factors involved but the bottom line is that the conversion to HD in Canada is much behind that in the USA. This will be of increasing concern to programmers, broadcasters and distributors alike, as the US deadline for full DTV cutover and an end to NTSC occurs in 2009. While the current "Market Driven" approach in Canada is attractive to many, the results leave much to be desired, if the Canadian TV industry is to remain competitive and prosper. What are the solutions? Let's here from you.

I am still a little confused about HD broadcasts. Are programs that are said to be broadcast in HD, only broadcast in High Defition on HD channels...or for that particular program, is the broadcast coming through in High Definition on the regular channel? For example, my cable company has a CBS-HD channel, channel 302....and a 'regular' CBS channel (non-HD), channel 12? When they say a particular football game is being broadcast in HD, does that mean the signal is coming through in High Definition on both the regular channel (12) and the HD channel (302), or does that just mean the game is coming through in High Definition only on the HD Channel (302)? I've noticed picture quality on the regular channel (12) seems to be a little bet better than 'normal' when a program is said to be broadcast in HD, but just curious if that is because the program is being broadcast in HD on channel (12) or if that is just a coincidence?

HDTV CONVERSION DEADLINE
Hello,
Could you please advise as to when ALL TV broadcast is to be HDTV?
Thanks,
Comment from Admin.
That date is undetermined in both Canada and the USA. The only firm date at present is that the turn-off of analog NTSC television in the US is foreseen for January 2009. This means that all over-the-air broadcasting will be digital and much, but not all, of it will likely be in HDTV. In Canada, there are no hard dates set, only a decision to adopt a “market-driven” approach to DTV implementation. The action in the USA will likely change that approach, as Canadian broadcasters come to grips with the loss of viewers to competing services in HDTV.

I can't tell you how disappointed I am that the CFL playoffs and Grey Cup will not be shown in HD. It's almost not worth watching the games as the quality is so poor. Yes, you do get spoiled by watching sports in HD...I can only hope that Formula 1 might go HD next year!

Videotron drops Discovery HD Why has Videotron Dropped Discovery HD, just as the service finally became a true HD channel with it’s own programming?
Videotron says that Discovery dropped them, not the other way around. I have seen it on someone else’s HDTV (who has ExpressVu). It is spectacular.
Are we going through another fight between Quebecor (who owns Videotron) and Bell (who owns CTV)?
All I know is that I feel cheated (I am not the only one), and I am not getting answers. I am starting to regret being a Videotron customer.
Comment from Admin.
Videotron and Discovery have been unable to agree to the business terms for the "new" Discovery HD which launched in late December. Discussions between the parties continue and it is expected that this will be resolved in the near future and the new Discovery HD made available to all of Videotron’s subscribers.

I have been told be an executive at one of Canada's premiere broadcaster's that consumer's switching over to HD TV's is actually "detrimental to their current business model". His reason had something to do with the inability to track ratings for HD broadcasts (BDU's???), and subsequent lost revenue.
Keep in mind that this broadcaster has probably the HIGHEST amount of HD content in Canada! Is there some strange phenomena in the industry that is being kept quiet here, or what?

Re: Canadian HDTV Programming
What’s all this? I just bought an HDTV, and I can't even use it without spending another $400-$800 to get a receiver just to watch 4 channels. Which on anytime of the week only show a few hours each of HD television anyway. Come on, get with the demand. I guarantee the first company that steps up to the plate and offer HDTV through satellite or normal cable will make a killing. 2009, ya right. We're not talking about politics deciding these things; it'll take the Canadian politicians until 2009 to even start thinking about it. Late!
Comment from Admin.
Right on. The Canadian television industry has a long way to go in bringing a full HDTV schedule to the viewers and in the interim, those who have invested in HDTV equipment are not getting anything near its full benefit. CDTV is making a considerable effort to facilitate a move to full HDTV production and broadcasting and there are some encouraging signs, but much remains to be done.

HD and SD broadcast standards
I am writing an article for POV magazine re broadcasters requirements for cameras and formats. Many Canadian broadcasters are getting more particular on the acquistion formats and for instance rejecting shows shot on camcorders etc. Are there any good sources or sites or articles that lay out new broadcasters requirements?
Comment from Admin.
Take a look at the HDTV Producer’s Primer on this site in the section HD Production Tools and elsewhere. There is a lot of new and useful information there.

Room for channels?
Please help me understand - are all channels eventually supposed to be in HD including kids’ channels and news channels etc? Also, I understand HD channels take up a lot of bandwidth? will their be room for all the channels?
Comment from Admin.
A few notes to help an understanding of the channel question.
1. Current analog over-the-air (OTA) and cable TV channels require a bandwidth of 6MHz. Over-the-air channels are numbered from 2 through 69 currently. Cable systems can carry more channels, dependent on the technology used and the bandwidth required for digital channels and other services (e.g. Internet).
2. Digital channels make much more efficient use of bandwidth, both OTA and on cable. Transmission of a 4:3 standard definition picture and accompanying sound can be carried in a 4 Mbps stream that would have an equivalent bandwidth occupancy of 1.2 MHz OTA (i.e. 5 programs carried digitally in the same 6MHz bandwidth as a single analog program). Cable system can carry this in even less bandwidth. New coding techniques coming into use can reduce the required bit rate down near 2 Mbps for a high quality SD picture and sound program.
3. Transmission of an HDTV program digitally requires 12 – 14 Mbps of data rate, with an equivalent bandwidth occupancy of 3.7 – 4.3 MHz of analog bandwidth for OTA transmission. Cable can do better with an equivalent bandwidth occupancy of some 2.7 MHz, thus allowing the transmission of two HD and one SD programs in the 6MHz channel.
4. The key here is that digital transmission is far more efficient in the use of bandwidth and more flexible in the kinds of programs it can carry. For instance a single OTA channel in 6 MHz might carry 4 or 5 SD programs at one time and switch to the carriage of an HD program and an SD program at other times.
5. The future thus lies in using digital TV which enables HDTV for those programs needing it and efficient transmission of SD programs (or even lower definition programs) for other programs. Analog television in contrast can offer only one format, NTSC, in the 6MHz channel.
Yes, the bandwidth of both OTA services, cable and satellite is limited, by good management of these resources, enabled by digital transmission, we can accommodate an expanding channel universe and tailor the capacity demands to the required quality of service.
