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
: 480 x 224 byte
Cb (color difference signal B-Y) data
: 160 x 112 byte
21,120 byte
Cr (color difference signal R-Y) data
: 160 x 112 byte
1/7
Total
: 143,360 byte
21,120 byte
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.
