TW6869-TA1-CRH Video Decoder IC DVR 144-TQFP (20x20)
The TW6869 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 eightchannel 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.
TW6869 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 PCIex1 interface. TW6869 is able to simultaneously decode and transfer 8 real time D1 video, or up to 32 channel nonreal time D1, plus 8 channel audio.
TW6869 decreases the complexity and workload of client-side software development, and significantly reduces the strains on PC hardware and resources. TW6869 also includes a software development kit (SDK) with Windows and Linux compliant drivers and reference application software.
