RCA cable as component ?

[RobertN]

just wondering if there is any difference apart from the price between a rca red white yellow cable and a component red green blue cable

also is a coaxial digital audio cable different froom a standard rca cable

i know these work but am i degrading the quality ?

Well basically the red, white and yellow cable is a Composite cable which gives the worst or one of the worst quality pictures. Component cables can give near HD quality pictures.

So Composite = Crap picture and Component = good picture.

I believe the poster is just talking about using the physical cable, the biggest difference is audio grade RCA cables are (I believe) normally 50ohm impedance, while Componant Video, and RCA/SPDIF are 75ohm impedance.

The higher impedance cable reduces signal reflections within the cable, giving better quality for the extra bandwidth required for SPDif, and Video needs.

While the cheap audio cables will work, they will certainly not even be good enough for Standard Def/Componant, let alone hidef. I used one myself for a couple of days because I forgot to buy a componant cable with my HD set, but it was certainly a noticeable improvement when I bought a proper grade componant cable later.

i tried hooking up my sony kdl-40w200 to my pc using some cheap rca's for a component hookup. its passable, but there was noticable ghosting. still, id needa 10m lead to connect my tv to my pc and tbh i dont fancy buying a 10m dvi>hdmi lead, they are so expensive

cheers for the replys was thinking of extending my xbox 360 leads component and optical to about 10m

so i can put it in the next room and play games in silence as the wirless controller works fine in the next room

sounds like i need component leads cheapest i can see is about £16 and about £6 for the optical for 10m

i was thinking just connect the xbox component to the 10m with a coupler
do you think this would be ok
