The Video Input Processor (VIP) is a combination of a
two-channel analog preprocessing circuit including source
selection, anti-aliasing filter and ADC, an automatic clamp
and gain control, a Clock Generation Circuit (CGC), a
digital multi-standard decoder (PAL BGHI, PAL M, PAL N,
NTSC M and NTSC N), a brightness/contrast/saturation
control circuit and a colour space matrix (see Fig.1).
The CMOS circuit SAA7111, analog front-end and digital
video decoder, is a highly integrated circuit for desktop
video applications. The decoder is based on the principle
of line-locked clock decoding and is able to decode the
colour of PAL and NTSC signals into CCIR-601
compatible colour component values. The SAA7111
accepts as analog inputs CVBS or S-video (Y/C) from
TV or VTR sources. The circuit is I2C-bus controlled.
