Axiom Home Page Forums General Discussion Home Theater Why Denon Receivers?

Since I'm much more familiar with computer stuff, I used "increasing its resolution" from the sense of increasing the resolution of the final image (i.e. more pixels with 720p than 480p). I didn't mean to imply that one can get more information/detail than the original image has. I realize that interpolation is no more than a extrapolation of what the image might've looked like if it had been recorded at a higher resolution, but it's nothing more than a "guess".

I wonder if I'm just overly fixated on the video processing, like what Faroudja or DVDO offer. Those products get very good reviews (and cost a pretty penny), so I assume that there's some merit to them. I guess it's also b/c I'm stuck with game consoles that I love but only output to 480i/p, so I'm trying to find a way to "spiff up" the output. I may also be biased b/c I have one of the earlier 19" LCD monitor (back when they cost >$700), which does a pretty crappy job of scaling anything that's not its native resolution. So, I try to run everything at its native resolution to avoid to monitor's internal scaler. Perhaps I'm making the same assumptions about 720p projectors, so that's why I'm trying to scale everything up to 720p before it's sent to the projector ...

Oh no, I think cables is due.

Sure, you can play it in your CD player, and maybe you even get some pseudo stereo added in with the decompression engine, but the quality can't possibly get any better than the source 96k mono mp3.

I'm with DW and JohnK on this.
I've seen two "upscaling" dvdps and there was virtually NO change at all. The increased resolution pictures actually just looked more grainy like someone over applied sharpness in Corel Photopaint to an image and that is something which is not "better", different sure, but definitely not "higher resolution".

One cannot make more pixels out of less except by using algorithms to assume what might be in the missing pixel places. You can certainly "make up" the 720p from 480, but it is not going to look like a true 720 signal which has EVERY pixel filled in from the original visual source. Perhaps there is a DSP out there that really is good at this and i haven't seen it yet, let alone any good in-store demos where they "try" to show you this.

Until then, garbage in, garbage out applies.

Now upconversion with the receiver outs can be handy by plugging in 2 or 3 sources of component cable sources so you can switch b/w them using only the receiver.

Oh my!, I bet Ken's wife is holding him down right now from going Crazyyyyyy. "Old-Timers"? "Lets get ready to rumbleeeeeeeeeeeeee"

heck, I'm happy to have the discussion-I've always had my 'feelings' about things like video conversion and it is interesting to hear the opinions of others.

As far as the native resolution on LCD monitors vs a projector I think you are safe-but again, I'm not sure. Using other than the native resolution on an LCD looks bad because of how the image is displayed. It has a little widget for each pixel on the screen-so if you run in a differet resolution it has to scale the image appropriately. I don't think that projectors have to do this-I use them at work and so long as you don't go beyond the native resolution the image always looks accurate to me.

What you experienced on the LCD though might help show my point. The LCD has to take an insufficient amount of data to fill its screen when you run in a lower resolution. The same will be true when the receiver takes your 480i input from the PS2 and tries to turn it into a 720p output on the TV. The problem hopefully won't be as bad as the LCD-but, and I've never tried this and I will be soon, if the receiver takes a 4:3 image and stretches it to 16:9 to acheive 720p then the picture will not be accurate unless the game supports a widescreen video mode. Hopefully the receivers have a way to switch between 4:3 and 16:9 or I'm probably not going to be happy with the conversion.

I'll be going through this in a couple of weeks. I'd try it out now but all my spare cables are packed up for the move. I'll post back on how it goes.

Like Ken is resisting his wife holding him down eh?

Our Toshiba has 4 aspect ratios and inevitably one of them can make everyone's heads look like Stewie Griffin.
