Rev.1.00
Feb 15, 2016 4-in-1 Video Decoders with PCI Express Media Bridge
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. Features 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. Integrated eight video analog anti-alias filters and 10-bit
CMOS ADCs 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. Applications Video Decoders Accepts all NTSC(M/N/4.43)/
PAL(B/D/G/H/I/K/L/M/N/60) standards with auto …
