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 can also increase the feature of a security system.
