1.3.10 Function block
TV / Video processing
- on A10 SSB , processing TV and video I/O signal to analog RGB output .
Video decoder
- SAA7118 , decoder analog RGB signal to CCIR 656 8 bit format digital
Signal
De-interlace
- FLI2200 , further process the 8 bit CCIR 656 format digital signal and
transfer to CCIR601 16 bit format digital signal output to Scaler IC
Scaler (JagASM)
a.) ADC
- brightness control
- contrast control
- R.G.B. sub contrast control
- sample the input video signal according to its pixel rate to form a digital
data for format converter
b.) Format converter
- convert the data from ADC to a LCD panel acceptable data format
- zoom the input video to a full screen display
