Analog Video Decoder

 4 CVBS analog inputs fed into 4 sets of video decoder accept all NTSC(M/N/4.43) / PAL (B/D/G/H/I/K/L/M/N/60) standards with auto detection

 Integrated video analog anti-aliasing filters and 10 bit CMOS ADCs for each video decoder

 High performance adaptive 4H comb filters for all NTSC/PAL standards

 IF compensation filter for improvement of color demodulation

 Color Transient Improvement (CTI)

 Automatic white peak control

 Programmable hue, saturation, contrast, brightness and sharpness

 Proprietary fast video locking system for non-real-time application

 Noise Reduction to remove impulse noise
