Y

Luminance signal

 

 

 

 

 

YPbPr

Component video (Y= Luminance, Pb/

 

 

 

 

 

 

Pr= Colour difference signals B-Y and

 

 

 

 

 

 

R-Y, other amplitudes w.r.t. to YUV)

 

 

 

 

 

Y/C

Y consists of luminance signal,

 

 

 

 

 

 

blanking level and sync; C consists of

 

 

 

 

 

 

chroma (colour) signal

 

 

 

 

 

Y-OUT

Luminance-signal

 

 

 

 

 

YUV

Colour space used by the NTSC and

 

 

 

 

 

 

PAL video systems. Y is the luminance

 

 

 

 

 

 

and U/V are the colour difference

 

 

 

 

 

 

signals
