Data Compressor
The color difference and the luminance data is compressed about 1/7 to increase the
numer of images in memory. Up to 96 images can be stored.
Y (luminance siganal) data
Cb (color difference signal B-Y) data
Cr (color difference signal R-Y) data
Encoder
The color and the luminance data are mixed internally to make the video signal, and
send it to the linear PCB and the video out terminal.
