Video Up-Conversion...do I need it?

472 Views 4 Replies 5 Participants Last post by  jeffK987
First of all, what is it? and do I need it?

Comparing the Marantz 4600 and 5600, and noticed the 4600 uploads to S video while the 5600 is up to the component.

I have a Pioneer Plasma (from costco I think 4304). I don't want to get a receiver that isn't on the same level with the tv.

Appreciate your help.

I'd like to know this, as well. Would there be a point in running a VCR (composite or s-video) through a reciever that upconverts to component? It'd seem to me that there'd be an overall quality loss for short runs due to the conversion, but maybe not.

The point of up-conversion, or transcoding as it's more properly called, is to give the user a single video cable to his display for all video sources. Signals that oringinate as composite video, S-video or component video without needing to change video inputs on the TV. Most users find this a great convenience.


The transcoding process shouldn't result in a loss of quality. However, be aware that composite video from a VCR may not look good when played on a high performace display whether it is upconverted or not. The fact is that most composite video signals are of low quality to begin with and the transcoding process can't make a silk purse out of that sow's ear.

Also many times with video transcoding from a VCR up to component, you can also run into TBC problems.

And if you are so unlucky as to experience that, then you definitely will get a worse, or even no picture at all.
I started using upconverting but vcr composite in to avr component out had chopping or weird colors displayed. Went with each video source directly to TV & audio to avr. With this I can watch tv (sports) and listen to music.
