DATASHEET TW6865 FN8304 Rev.1.00 4-in-1 Video Decoders with PCI Express Media Bridge Feb 15, 2016 The TW6865 is a highly integrated solution that supports Features multi-channel video and audio capture via PCIe x1 interface for PC DVR system and video analytic application. It contains high Video Decoders quality four-channel NTSC/PAL/SECAM video decoders that Accepts all NTSC(M/N/4.43)/ convert analog composite video signal to digital component PAL(B/D/G/H/I/K/L/M/N/60) standards with auto YCbCr data and utilize adaptive 4H comb filter for separating detection luminance and chrominance to reduce cross noise artifacts. Integrated eight video analog anti-alias filters and 10-bit The TW6865 contains a high performance proprietary DMA CMOS ADCs controller that fully optimizes the utilization of PCIe x1 bandwidth and enables it to transfer video and audio data at a IF compensation filter for improvement of color high throughput rate that closely approaches the theoretical demodulation limit of PCIe x1 interface. The TW6865 is able to Color Transient Improvement (CTI) simultaneously decode and transfer 4 real time D1 video, or White peak AGC control up to 16-channel non-real time D1, plus 8-channel audio. Programmable hue, saturation, contrast, brightness and The TW6865 decreases the complexity and workload of sharpness client-side software development, and significantly reduces High quality proprietary fast video locking system for non the strains on PC hardware and resources. TW6865 also real time application includes a Software Development Kit (SDK) with Windows and Linux compliant drivers and reference application software.
