TW6869
8-in-1 Video Decoders with PCI Express Media Bridge
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 …
