(3) 4:2:2:A method of representing video that records the luminance signal
and corresponding color signal for a single scan line in a 4:2 ratio, ensuring excellent color fidelity and limiting color degradation during multiple encoding and decoding steps.
The unit features Composite video outputs operating at 1.0Vp-p (75 ohm) Sync Negative, S video outputs with Luminance Signal
atl.0Vp-p (75ohm load)and Color Signal at 0.286Vp-p (75ohm load), and Component video outputs--Y Level at 1Vp-p (75ohm load), Pb Level at 0.7Vp-p (75ohm load), and Pr Level at 0.7Vp-p (75 ohm load).
Error metrics are only computed on the luminance signal
, so the pixel values f(i,j) range between black (0) and white (255).
The inclusion of color at 3.58 MHz means information must be taken away from the luminance signal
. That loss of information results in a loss of picture details.
The relative contributions of color and luminance signals
towards the visuomotor localization of targets in human peripheral vision.
