TW6865-TA1-CRH

The TW6865 is a highly integrated solution that supports multi-channel video and audio capture via PCIe x1 interface for PC DVR system and video analytic application. It contains high quality four-channel NTSC/PAL/SECAM video decoders that convert analog composite video signal to digital component YCbCr data and utilize adaptive 4H comb filter for separating luminance and chrominance to reduce cross noise artifacts. The TW6865 contains a high performance proprietary DMA controller that fully optimizes the utilization of PCIe x1 bandwidth and enables it to transfer video and audio data at a high throughput rate that closely approaches the theoretical limit of PCIe x1 interface. The TW6865 is able to simultaneously decode and transfer 4 real time D1 video, or up to 16-channel non-real time D1, plus 8-channel audio. The TW6865 decreases the complexity and workload of client-side software development, and significantly reduces the strains on PC hardware and resources. TW6865 also includes a Software Development Kit (SDK) with Windows and Linux compliant drivers and reference application software.
