View Full Version : Video conversion - Amp or separate box???
01-09-2003, 10:21 AM
I have a Panasonic Plasma screen, which I am sure you know has a Component input.
I am looking at ways of getting all my sources (will be a HK DVD 25, and Pace Freeview box (one of the old ondigital ones) into component.
Current favourite (since I don't really have an AV Amp) is the DENON 3803
But another thought is something like the Denon 3803/pioneer 2011 or maybe even try going up a level to the A1S and AX10 and a separate video conversion box.
the theory going that if a separate box is dedicated to the conversion it is likely to be better than a "cheap/generic/standard" converter stuffed into an amp.
Any thoughts? Are there any other amplifiers out there that do video conversion?
thanks in advance

I am not familiar with the panny plasma nor the pace freeview box, but perhaps this gives you another idea.
If the panny accepts RGB with sync on green on the component inputs, like my projector does, and the pace freeview box can output RGB from its scart, you could get a RGB to component converter (transcoder) and switch it through either AMP without any conversion.....

That is kind of what I was thinking when I mentioned the separate box for video conversion... I guess what I don't know is are they any better quality (e.g. affect the picture quality less) than the amplifier which of course has a primary function of amplification NOT video conversion.
Do you have any commendations re; separate boxes?
I would end up with possibly 3 inputs - 2x RGB and 1 Component

I would think that the quality is going to be much better, based on the following.
If you output RGB from the source, all you are doing in principle is moving the sync to be incorporated into the green. When you use up-conversion from lets say the Denon or the new Sony amps, you are converting a composite or sVideo signal into component. I do not know the details in depth, but the colorspace has to be seperated whilst that is already done for RGB.
I haven't use them myself yet, but are looking into the following devices:

Looks very flexible for when you are not certain which sync your plasma can accept, but dearer.
And definitely check this out.
I have got a feeling that they can provide you with specific advice for your plasma screen. Actually I have seen JS post on this forum as well. I am inclined to go for this one for my Sky+ as it is designed and produced in the UK as well.
I don't know about the de-interlacing skills of your plasma, but as a next upgrade you may want to think about adding a de-interlacer/scaler to your plasma with component inputs. Inbetween the AMP (doing the switching) and the screen to further the picture quality (or should that say stability)...Just a thought.
