Product Description
|
| The TW2816 includes
four high quality NTSC/PAL video decoders that convert
analog composite video signals to digital component
YCbCr data for security applications. The TW2816 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
TW2816 adopts image enhancement techniques such as IF
compensation filter, CTI and programmable peaking.
