The TW2804 includes four high quality NTSC / PAL video decoders,

which convert analog composite to digital component YCbCr for security

applications. The TW2804X contains four 10-bit A/D, proprietary

digital gain/clamp controllers, and utilizes proprietary techniques for

separating luminance & chrominance to reduce both cross-luminance

and cross-chrominance artifacts. The high performance dual scalers in

each channel offer two differently scaled video outputs with 54MHz ITU-R

BT.656 format for security system design. Four built-in motion detectors
