8.4 Hardware Specifications

The following section provides information about FM-VC main components and features.

8.4.1 Intersil TW6869 Video Decoder

The TW6869 is a highly integrated solution that supports multi-channel video and audio capture

via PCI Express x1 interface for PC DVR system and video analytic application. It contains high

quality eight channel NTSC/PAL/SECAM video decoders that convert analog composite video signal

to digital component YCbCr data. 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 PCI Express x1 bandwidth and enables it to transfer video and audio data at a high throughput

rate that closely approaches the theoretical limit of PCI Express x1 interface. TW6869 is able to

simultaneously decode and transfer 8 real time video streams, or up to 16 channel non-real time video

streams in FM-VC application, plus 8 real time audio channel.
