Got a flyer from The Source a couple of weeks back. I noticed this ad on one of the inside pages. It caught my eye because it looked unusual.
I guess that whole bankruptcy thing means you gotta cut costs, which evidently include fact-checkers.
I doubt that is what you are refereeing to, yet “10 times the resolution of a regular TV” would mean a resolution of 7200×4800 while HD TVs offers a maximum of 1920×1080.
Actually 7200×4800 would be 100 times the resolution (100 times the pixels), but you’re right, HD isn’t 10 times the resolution, it’s 6.
Nothing beats an ad for something that you can’t use because the service that it’s linked to isn’t offered where you live… unless Rogers started offering its cable service here in secret… :P
Back when I was starting in my field (so circa 2002), I used to periodically see want ads for a translator for Radio Shack in Barrie. The fact that the ad reappeared regularly was a bad sign, and I’m glad to have never applied.
HD is only 5x better than SD, not 10?
Also, why is the LCD display showing channel 4250?
Well I can only find obvious things like the fact that Rogers is not available in Quebec and that HDTV is not 10x the resolution of regular TV. Knowing you I’m sure there’s something more subtle in the ad but I can’t find it…
Well apparently it wasn’t obvious enough for The Source that Rogers TV isn’t in Quebec.
i don’t get it
The 5000 channel universe is here!
The 4250 is the model number of the terminal. Rogers Ontario is offering the 3250 (but it’s crap) and the 4250 (it’s also crap)…..No matter what, they are both crap…Videotron is offering the same models, actually the 4250 is the one that is currently offered by them and it’s about half the price of rogers!!!!
The mistake is offering a rogers HD box in Quebec, Rogers does not offer service in Quebec just as Videotron does not offer service in Ontario (Or any other part of Canada for that matter)
I miss Montreal all of a sudden…

A standard NTSC analog TV broadcast (“regular” TV) resolution is 440 x 480 = 211 200 pixels
Maximum HDTV resolution is 1920 x 1080 = 2 073 600 pixels
So the HDTV has 10x as many pixels as the NTSC standard. This standard is being phased out soon, and the new “regular” television standard has a higher resolution than NTSC. I have no idea how many broadcasters still broadcast in NTSC but this must be the basis of the claim in the ad.
True resolution, however, also depends on the physical dimensions of the TV screen itself. A larger TV screen has a lower resolution than a smaller screen with the same total number of pixels. That’s why small CRT TVs have a clearer picture than large ones. The total of number pixels on each screen is the same, but the resolution is higher on the small TV because each pixel is smaller. So any comparison of resolution are only meaningful if the size of the TV screen remains the same (which the add doesn’t make clear).
Having said that, for the same size screen, the ppi (pixels per inch) ratio between Max HDTV and NTSC is 1980:440, or about 4.5:1 in the horizontal direction, and 1080:480, or about 2.25:1. Of course, 4.5 x 2.25 is about 10, so maybe this is the basis of the claim.
(You’re talking about the “dot pitch”).
