Ya, in order to get an HD signal to your TV, the event has to be filmed in HD. So, even if you have HDTV and an HD receiver, and you are watching 'HD Programming', not everything will show up in HD. You will sometimes get those black bars on the side. In the upcoming years, we all hope they will standardize and there will certainly be more content available.

The problem is that there aren't that many HD trucks out there. For that reason, when networks don't have enough trucks to do all the games that weekend, they only produce HD for nationally broadcast, high profile games. HD cameras, gear, and post production costs are more expensive than SD too. That's why there are only a handful of local news are in HD. And why there are stations that have resisted upgrading to HD broadcasts for network programming.
Oh yeah, black bars doesn't mean that it's not in HD. There is 4:3 HD content out there. Lack of black bards doesn't mean that it's in HD. There is 16:9 SD content out there too.
You're confusing three things -- display aspect ratio, original aspect ratio and broadcast specifications. HD broadcasts can be in different combination of the last two. If the aspect ratio and broadcast specification match, there will be no black bars if your display matches (this is the case for both SD and HD). If they don't, you'll get black bars.Originally posted by: jiffylube1024
Well... Black bars are technically not HD since HD techinically is 1280X720 or 1980X1080 (progressive for the first, interlaced or progressive for the latter). So while you might get a 4:3 broadcast at HD resolutions, it's technically not true "HD" since it's not widescreen.

Of course, if you stretch or crop the image, you can eliminate black bars, but we'll stick to the original aspect ratio. So a 2.35 film will always show black bars in OAR, regardless of whether iit's SD or HD. Likewise, content filmed with a 4:3 AR with a HD transfer will always display black pillarboxing when show in OAR on a widescreen display.
IIRC, The Wizard of Oz, Gone with the Wind, Bambi, Frosty the Snowman, and Rudolph the Red Nosed Reindeer have all been broadcast in HD with a 4:3 aspect ratio.
high definition television (HDTV) ? High definition television has a resolution of
approximately twice that of conventional television in both the horizontal (H) and vertical
(V) dimensions and a picture aspect ratio (H × V) of 16:9. ITU-R Recommendation 1125
further defines ?HDTV quality? as the delivery of a television picture which is subjectively
identical with the interlaced HDTV studio standard.

That's for a television set, not television programming. True HD programming is in resolution of the transfer from source to broadcast. Do you mean to say there will never be an HD broadcast of The Wizard of Oz because when they took the original 35mm and telecined to HD format, they used the original 4:3 OAR? That you'd have to crop or stretch the Wizard of Oz to get a HD version of it?

HD must be broadcast as a widescreen (16x9) feed, but that doesn't mean you can't have a 4x3 source centered on the screen with random crap (or plain ol' black bars) in the wings.

To go back to the original question: much programming comes through local affiliates of major networks (NBC, ABC, CBS). If the local affiliate has no provision for broadcasting in HD, it doesn't matter what the original content is filmed in.

Like I said before side tracking into "black bars". there just aren't enough HD trucks out there yet. Sort of how like everyone and their sister has a local news chopper, but I can count on my fingers the number of them that are HD choppers. HD is more expensive, equipment is rarer, and newer. There are always people that resist change, both for financial reasons and because they're old fogeys.
