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