Default What about componet to HDMI converters?

What if you have a DVD player you like but you want the HDMI connection, there are Compontet cables 5 RCA to HDMI

Can i just get one of these and then keep the 480P SD dvd player i already have?

I think all i really want is 720P i dont really need 1080 but ide like it to atleast play at 720P

Anyon tried one of these before?

Never mind it looks like its going to need a converter box, the cable is extra. DOH!

In most cases, it won't make any difference as far as upscaling is concerned. HDMI is just a digital data connection, it doesn't do any upscaling, so you would need a scaler as well (which would already have an HDMI output on it, anyway).

You need something that takes Component Video at SD resolution and upscales it to HD, then takes audio (analog or digital) and merges it with the digital video to create an HDMI output. Something like:

http://www.antonline.com/p_AT-HD510VGA-NX_576557.htm

There aren't too many of them out there and they cost more than even a really good upscaling DVD player (Oppo, for example).

But your TV already upscales any signal to the native resolution of the display and you would still need to connect the 5 cables up between the DVD player and the scaler, so unless your HDTV doesn't have any Component Video inputs left, there would really be no point in doing this. Even then, it would be cheaper and simpler to just get a Component Video switch box.

If you're worried that a new upscaling DVD player won't be as good as your old DVD player, as long as you stay away from the cheapest stuff, like CyberHome, Apex and other brands you never heard of until a few years ago, you will probably be fine.

Yeah that is what im worried about, i have a feeling i wont really notice much difference.

I have a sony 301 DVD changer, wondering if i should sell it and get the 400 that has the HDMI out or just stick with what i have.

What about these? off e-bay?

I have seen complaints about bad analog to digital 'upconversion' in certain receivers, such as Onkyo and Sony. In fact, every THX-certified receiver in Onkyo's line has this in their owner's manuals:

For optimal video performance, THX recommends that video signals pass through the system without upconversion (e.g., component video input through to component video output).

My question about this $32 converter box is how good will the video conversion from analog to digital will be. (The audio is already digital, so there shouldn't be a problem converting optical/coax to HDMI.) I would expect some picture quality issues on the HDMI output of this thing.

Second, you should know that if you feed a 480p component signal into this converter, you are still going to get 480p on its HDMI output. So the question is why bother? The only thing you can possibly gain is some video artifacts that weren't there to start with.

So the upconverters have a prosessing in them that not on changes the size but kinda photoshops the images a little to make them look better?

Upconversion doesn't just increase the number of pixels, it creates the new pixels by blending them into the real pixels in the original image using mathematical interpolation--in essence filling in the space between the real pixels by estimating what the new pixels would have been like based on the pixels that already exist.

If all upconverison did was add pixels by making duplicates of the existing pixels, you would just end up with the same large, blocky picture you would have had if there had been no upconverison.

Simple interpolation tends to make the picture look less sharp, as it blends the real pixels together. Say the original DVD signal had a black pixel next to a white pixel. This would produce a sharp edge transition in the original image, but in the upscaled image, the interpolation would add pixels of varying shades of gray that would appear to blend the black into the white. This reduces the harsh pixelation you would notice if you blew a DVD image up on a large screen, but also makes edges softer, giving you the impression the picture is less sharp overall.

Some upscalers are smart and try to preserve edges, so the picture not only looks smoother overall, but still looks as sharp as the original.

Some upscalers use edge enhancement to create an image that appears sharper than the original image, but it can also lead to objectionable artifacts like halos around edges and somewhat of a "cartoony" look, with black lines around edges.

The Toshiba XDE-500 uses proprietary technology to do what, to my eyes, is the best upscaling I've seen on a DVD player, but some people absolutely hate the results as they see what is called "ringing" on the edges which to them looks annoying and artificial. Up close, I can see ringing also, but at normal viewing distance, all I see is a cleaner, sharper DVD picture (the result varies with the DVD, though--some older transfers, or generally poor transfers, look noisy, so I turn the sharpness feature off on those).

cool, wish i had the money to try different upscalers and pick out the best ones. Im gona try the samsung DVP5982

What is hapening when i use "zoom" on my tv? say im on an HD channel that says its in 1080 and is playing a 480SD movie. When im watching it i see these large black bands all around the image. The actual picture isnt filling my screen so i go into the setup and i use "zoom" now the movie fills my screen but it just looks a little more grainy. What is this called? and is it just taking the 480 image that is say pixal for pixal and making it larger 4 pixals =1 filling the screen edge to edge.

Letterbox = bars at top and bottom
Pillarbox = bars at the sides
Windowboxing occurs when an image appears centered in a television screen, with blank space on all four sides of the image, such as when a widescreen image that has been previously letterboxed to fit 1.33:1 is then pillarboxed to fit 16:9.

Why does windowboxing happen? Im getting sick of having to change all the different programs so they fill my screen.

I never had as much problems as i do now with these LCDs

"Windowbox
A term that is used to describe the blank bars (usually black in colour) all the way around an image when the letterbox effect and pillarbox effect occur simultaneously. It is most often the unintended result of viewing non-anamorphic letterboxed material on a widescreen display or when a 16:9 film is set to 4:3 (letterbox), but then shown on a 16:9 TV or other output device."


http://www.interbluray.co.uk/blu-ray...windowbox.html

Anamorphic vs. Non-anamorphic (1.85:1)

Anamorphic vs. Non-anamorphic (2.35:1)

"....or when a 16:9 film is set to 4:3 (letterbox), but then shown on a 16:9 TV or other output device."

The reason a 16:9 film (or other program) is converted to letterbox 4:3 is to accomodate people with older 4:3 TVs. When they see it, it is simply letterboxed. But then when you see it on your 16:9 TV, the TV automatically pillarboxes the image, resulting in black bars all around the picture. (Unless your TV is set for grey instead of black, in which case you see black on top and bottom and grey on the sides.)

Well i ordered 2 different componet converters, and i have an HD-A3 on the way and the phillips in my sig so ill do a compairison between my old Sony DVD player with the converter and the 2 upscaler machines.

The reason i wanted the upscaler is i have a 301 disk changer comming also so of those 3 players, i should find somthing i like.

Ide hope

The "zoom" function on a TV usually just effectively makes the pixels larger to fill the screen and degrades the image as a result.

The best DVD's for a Widescreen TV are those labeled "anamorphic" or "enhanced for 16:9 televisions" (available on virtually all recent releases). The image is squeezed horizontally on these discs to fit in a standard 4:3 window, so all of the horizontal and vertical information is preserved. When played back, your widescreen TV stretches them to fill the screen, undoing the squeeze and restoring the proper aspect ratio.

Letterbox discs lose vertical resolution, as they are "shrunk-down" to fit horizontally in a 4:3 window, and Full-Screen discs lose horizontal content, as they are cropped to fit in a 4:3 window.

I would just look for some reviews to help you find the best solution. For a long time, Oppo (http://www.oppodigital.com/) was regarded by many as making the best upconverting DVD players, particularly for the price. As I said, I personally consider the Toshiba XDE-500 (http://www.bestbuy.com/site/olspage....egories&ks=960) to be the best-performing upscaler I've seen and at less than $80 now, it's pretty cheap.

Unless the Component Converters you ordered are also upscalers, they aren't going to give you anything you don't already have. HMDI doesn't upscale, it simply transmits video and audio as a digital signal. Unless you spent some serious bucks, it's unlikely any outboard upscaler is going to be much better than the upscaler built into the TV and will likely be worse than the upscaling performed in an upconverting DVD player, where the player has access to data on the DVD that can improve the upscaling results.
