The TW6865 is a highly integrated solution that supports multi-channel video and audio capture over the PCIe x1 interface for PC DVR systems and video analytics applications. It contains a high-quality four-channel NTSC/PAL/SECAM video decoder, analog composite video signal conversion composed of digital YCbCr data, and utilizes an adaptive 4H comb filter to separate brightness and chroma to reduce cross-noise unnatural. The TW6865 includes a high-performance dedicated DMA controller that fully optimizes PCIe x1 bandwidth utilization, allowing it to transmit video and audio data at a high throughput rate close to the theoretical limits of the PCIex1 interface. The TW6865 is capable of simultaneously decoding and transmitting live D1 video or up to 16 channels of non-real-time D1, plus 8 channels of audio. The TW6865 reduces the complexity and workload of client software development, and significantly reduces the hardware and resources on the PC. The TW6865 also includes a software development kit (SDK) for Windows and Linux-compatible drivers and reference application software. TW8830
