The TW2815 includes four high quality NTSC/PAL video decoders that
convert analog composite video signal to digital component YCbCr data
for security applications. The TW2815 contains four 10 bit ADC and
proprietary clamp and gain controllers and utilizes a 4H comb filter for
separating luminance & chrominance to reduce cross noise artifacts. The
TW2815 adopts the image enhancement techniques such as IF
compensation filter, CTI and programmable peaking. The TW2815 also
includes an audio CODEC which has four audio Analog-to-Digital
converters and one Digital-to-Analog converter. A built-in audio controller
can generate digital outputs for recording/mixing and accepts digital
input for playback.
