gus. [wouldn't component vs composite video is analogous to component vs integrated audio in relative integrity, or performance.] the sony news is very timely...and you are absolutely correct about the potential effect this would have on ampex i would not underestimate the number of interested parties waiting for the appellate court's decision.

Gus, though I am far from expert ....well on my way to learning less and less about more and more til I know nothing about everything..... I can contribute a tiny bit from general home theatre reading I have done. Video component outputs and inputs separate the three components of a digital video signal ( Y, R-Y, and B-Y) Component video is thus a method of transfer and storage of video information and storage in separate components.( I do not understand the 4th wire unless it is indeed a " clock" element. Will check around.) Today's standard formats - PAL , NTSC, and SECAM - transfer and store "combined" signals which are derived from the three channels of RGB information. An example of one edge of component video output and input is that absolute black is set at 0. So you get about a 10% pop in chiaroscuro dynamic range - which may not sound like much, but light and shadow info has a pronounced effect on the visceral impact on dramatic visual detail. Some high end video equipment nowadays have these component inputs and outputs. Most do not as of yet. I personally would sure welcome any posts from true experts on this matter. PS..have read that the nature of the video " clock " ( Mitsu litigation) used has substantial effect upon performance in a variety of digital applications. Audio and video.

Did a little browsing - using that usually terrific search engine Randy brought to our attention . Definitions of component and composite video. <<Component Video: Our color television system starts out with three channels of information; Red, Green, & Blue (RGB). In the process of translating these channels to a single composite video signal they are often first converted to Y, R-Y, and B-Y. Both three channel systems, RGB and Y, R - Y, B - Y are component video signals. They are the components that eventually make up the composite video signal. Much higher program production quality is possible if the elements are assembled in the component domain. One of the advantages DVD has over the laserdisc format is that it is component based. Composite Video: A single video signal that contains luminance, color, and synchronization information. NTSC, PAL, and SECAM are all examples of composite video systems. >> If Composite Video is luminance chrominance and synchronization - I would guess the fourth wire in a component method is also. Am I mistaken, or isn't some form or another of a digital " clock" used for synchronization? The handy site for Video terms in layman's language. videoessentials.com
