PCI Based DVR IC Solutions
Target Application
The TW6868 is a highly integrated single-chip solution that supports multi-channel real time video and audio
capture via PCIe x1 interface for PC DVR applications. It contains four high quality NTSC/PAL/SECAM video
decoders that convert analog composite video signal to digital component YCbCr data, and utilizes an adaptive
4H comb filter for separating luminance and chrominance to reduce cross noise artifacts. TW6868 contains a high
performance proprietary DMA controller that fully utilizes the PCIe x1 bandwidth, enabling it to transfer video and
audio data at optimal throughput rate.
TW6868 has the versatility to support a wide variety of video applications, including decoding and transferring 4
channel real-time D1 video, or up to 16 channel non-real-time video simultaneously. It supports multiple video
display formats such as D1, half D1 and CIF. By implementing Techwell’s advanced proprietary video-switching
technology, TW6868 possesses industry-leading video-locking speed in non-real-time switching mode.
addition, coupled with an external Techwell four-channel decoder, TW6868 can transfer up to 8 channels of real-
time D1 video and 9 channels of audio output.
