The TW2824 contains four 10-bit analog-to-digital converters, proprietary digital High performance 2x zoom for horizontal and gain/clamp controller, high quality Y/C separator to vertical direction reduce cross-noise and high performance dual scaler to provide various pictures. Four built-in Supports save and recall function motion and blind detectors can increase the feature Last image capture when video-loss of the security system. The TW2824 has a flexible video display controller including QUAD and MUX Extendable to 8-/12-/16-channel video controller basic functions. The TW2824 also has an excellent using cascade connection graphic overlay function which displays character/bitmap, box and mouse pointer. The Path-to-path cascade TW2824 contains two video encoders with four 10- Character/bitmap overlay for OSD bit digital-to-analog converters for providing 2 composite or S-video. 16 programmable single boxes 4 2D arrayed boxes for motion result display Features Mouse pointer overlay Four Video Decoders Dual Video Encoders Accepts all NTSC/PAL standard formats with auto detection 2 path digital outputs with ITU-R BT.656 standards Integrated four anti-aliasing filters and 10-bit CMOS ADCs 2 path analog outputs with all analog NTSC/PAL standards High performance adaptive comb filters for all NTSC/PAL standards Supports CVBS or S-video for each path IF compensation filter for improvement of color Programmable bandwidth for luminance and demodulation chrominance path PAL delay lines for correcting PAL phase errors Four 10-bit video CMOS DACs Programmable hue, saturation, contrast, Applications brightness and sharpness Analog QUAD/MUX system Dual high performance horizontal and vertical scaler for each channel. 4-/8-/16-channel DVR system Four built-in motion detectors with 16x12 cells Car rear vision system and blind detectors Hair shop system Dual Video Controllers Additional 1-channel digital input for playback or cascade operation Full live/strobe/switch function Auto sequence switch with 64 queues and/or manual switch by interrupt FN7738 Rev. 0.00 Page 1 of 2 February 2, 2011 Block Diagram ADDRX/BA1X/BA0X/RASBX/CASBX/WENBX/DQMX/DATAX PBCLK PBIN ITU-R BT656 Decoder Memory Interface PBVALID H/V Scaler VIN0A DAC VOUTYX OSD Color ADC H/V Scaler Write Read Box Video Decoder VIN0B Control Control Mouse Encoder Motion Detect Overlay DAC VOUTCX H/V Scaler ITU-R BT656 Encoder VDOUTX VIN1A Color ADC H/V Scaler Decoder VIN1B Motion Detect HSENC Encoder Timing Interface VSENC FLDENC H/V Scaler VIN2A Color ADC H/V Scaler ITU-R BT656 Encoder VDOUTY Decoder VIN2B Motion Detect DAC VOUTYY OSD Write Read Box Video H/V Scaler Control Control Mouse Encoder VIN3A Overlay DAC Color VOUTCY ADC H/V Scaler Decoder VIN3B Motion Detect Memory Interface HSPB HCSB0 HCSB1 CLK27ENCX HALE HOST Interface IRQ Interface Clock Generator CLK27ENCY HRDB HWRB HDAT IRQ ADDRY/BA0Y/RASBY/CASBY/WENBY/DQMY/DATAY CLK54I Copyright Intersil Americas LLC 2011.
