The TW2836 contains Programmable hue, saturation, contrast, four built-in analog anti-aliasing filters, four 10 bit brightness and sharpness Analog-to-Digital converters, and proprietary High performance horizontal and vertical scaler digital gain/clamp controller, high quality Y/C for each path including playback input separator to reduce cross-noise and high Fast video locking system for non-realtime performance free scaler. Four built-in motion, application blind and night detectors can increase the Four built-in motion detectors with 16X12 cells security system feature. The TW2836 has and blind and night detectors flexible video display/record/playback controller, Additional digital input for playback with ITU-R including basic display and MUX functions. The BT.656 standard TW2836 also has an excellent graphic overlay Auto cropping / strobe for playback input with function that displays bitmap for OSD, single box, Channel ID decoder 2D array box, and mouse pointer. The built-in Supports four channel full D1 record mode channel ID CODEC allows auto decoding and displaying during playback and the additional Dual Video Controllers scaler on the playback supports multi-cropping Supports full triplex function with 4ch live, function of the same field or frame image. The 4ch playback display and 4ch record output TW2836 contains two video encoders with three Analog/Digital channel ID CODEC for record 10 bit Digital-to-Analog converters to provide 2 and playback application composite or S-video.
