Many of you have probably watched an HD broadcast that has been letterboxed on top and bottom as well as both sides. My question is whether or not the left and right cropped picture is really an HD signal or something like 480i or 480p being rescaled. I watched Survivor on HD, it was HD quality, but it was cropped on all sides. Do they really broadcast in HD in a 4:3 format, or is it scaled?

Survivor is not in HD. -
They can (and do) broadcast it in a 4:3 ratio...
We watched part of the Pro-Bowl and it was in a 4:3 ratio, but definitely in high definition. It sucked bad...I'm not sure why ESPN did that, nor do I understand what the reasoning is behind it.
But some things one can tell is HD, but not in a 16:9 ratio.Digital Audio makes me Happy.

It's not HD, just SD material shown on an HD channel. The extra res does help and I find is generally better PQ than SD but nowhere close to HD. Consider it similar to "upsampled".JasonComment

Well, if it is SD on a HD channel, it is much better than SD on the regular channels with my 40" tube. So, is an external scaler capable of that quality with SD chanels? Or, is it cost prohibitve?____________________

"Double Letterboxing" is one of my all-time biggest complaints about HDTV. If something must be filmed in SD 4:3 aspect ratio, great. Then broadcast it as such, and I'll watch it in the native 4:3 aspect ratio and accept the black bars on the left and right of the screen. But if something is natively widescreen, then PLEASE, PLEASE, don't box it into a 4:3 screen with letterboxing at the top and bottom and then broadcast it again in 16:9 with boxing on the sides.
Things that are natively widescreen, when broadcast over HDTV, should only have any necessary black boxing at the top and bottom of the screen. (i.e. 2.35/1 movies) Even if it's just upconverted, not a true HD transfer.

Well, we're safe for now. Thank goodness we're in a bowling alley.

If it's not HD, I'm completely fooled, because I've seen the same game broadcast on ABC and on ESPN one time and both where in HD, one was 16x9 the other was 4:3... there was no quality loss in the 4:3 section when you switched between the two channels....... There was no "letterboxing" on the top and bottom of the broadcast, it was just 4:3 with the HD logos on the sides....
That's the way the whole Pro Bowl came over for me... ...and I doubt they wouldn't put that in 16x9...
So if that's SD, I don't need HD! lol.

Well it all depends on what tv you have and viewing distance, and you eye side
If you have a true HDTV I think you could see a difference but since most HDTV's are still EDTV's imo the differences are small. I didn't see any difference between de panny 42'' ED and HDTV.Comment

The only complaint I have about this set is that I have to watch most of the broadcast stations in the Theater 1 or Theater 2(Ex. E.R.) mode in order to eliminate the grey or black bars and prevent any burn-in. I have ordered the Digital Video Essentials DVD in hopes that I might be able to adjust... -

Signal-to-Noise Ratio (SNR)
The signal-to-noise ratio (SNR) is an important parameter that helps evaluate the performance and quality of the audio output. In the context of audio, SNR refers specifically to the ratio of the desired audio signal (the sound produced by the loudspeaker driver) to the background noise generated by the speaker itself or the overall system.
The formula to calculate SNR in decibels is:...
SNR (dB) = 10⋅log10(PowerSignal/PowerNoise)25 July 2023, 15:20 Tuesday -
