Not exactly. Standard Televisions output 60 interlaced frames per second with 480 scanlines. The catch is that each frame only displays every other row of pixels. This alternates back and forth to create an interlaced image. Progressive scan is a mode where a television or monitor will scan ahead (or progressively) and output 30 full frames per second.Originally Posted by Kris
You get an extra boost just using these cables - even if you don't use progressive scan. Video signals are composed of three individual signals - Red, Green, and Blue. Your standard Composite cables compress all three of these signals and trasmit them over a single cable. This is a ludicrous idea - that your sound is actually given more bandwith than your video signal (Sound - red and White / Video - Yellow).
S-Video cables work better, but I won't go into an explanation here.
Component video cables work best (as far as analog signals are concerned) and allow for the video signal to be sent as its separate individual components - Red, Green, and Blue. This helps big time with distortion and color bleeding and sharpness.
Progressive scan ices the cake off real nice by displaying a full image in each frame, rather than playing magic tricks and letting your brain compile the interlaced image.
So, what I'm getting at is that 480i (interlaced) and 480p (progressive) most put out the same amount of pixels per second, progressive scan just does it in a better way.
Now for a tip - don't think that more expensive means better in terms of component cables. You'll usually see longer cables cost a lot more than their shorter counterparts and be tempted to think they must be nicer. Don't fall for it; electric signals deteriorate over distance in a non-linear fashion. The reason longer cables cost more is because they have to be made of better materials to acheive the same distortion level as shorter cables.
The shor tof it is this: don't buy a longer cab;e than you need unless you like wasting money. You won't notice a difference in visual performance.
