The TW2834 contains four built-in auto detection analog anti-aliasing filters, four 10-bit analog-to-digital converters, proprietary digital Integrated four analog anti-aliasing filters and gain/clamp controller, high quality Y/C separator to four 10-bit CMOS ADCs reduce cross-noise and high performance free High performance adaptive comb filters for all scaler. Four built-in motion and blind detectors can NTSC/PAL standards increase the feature of the security system. The IF compensation filter for improvement of color TW2834 has a flexible video display controller demodulation including basic QUAD and MUX functions. The TW2834 also has an excellent graphic overlay PAL delay lines for correcting PAL phase errors function that displays character/bitmap for OSD, Programmable hue, saturation, contrast, single box, 2D array box and mouse pointer. The brightness and sharpness built-in channel ID CODEC allows auto decoding and High performance horizontal and vertical scaler displaying during playback and the additional scaler for each path including playback input on the playback supports multicropping function of the same field or frame image. The TW2834 Fast video locking system for non-realtime contains two video encoders with four 10-bit applications digital-to-analog converters for providing 2 Four built-in motion detectors with 16x12 cells composite or S-video. The TW2834 also can be and blind detectors extended up to 8-/16-channel video controller using Additional digital input for playback with ITU-R chip-to-chip cascade connection.
