Cameras

The TW2815 includes four high quality NTSC/PAL video decoders that

convert analog composite video signals to digital component YCbCr data

for security applications. The TW2815 contains four 10 bit ADCs and

proprietary clamp and gain controllers and utilizes 4H comb filters for

separating luminance & chrominance to reduce cross noise artifacts. The

TW2815 adopts 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.
