Xintekvideo s Digital Co-Channel Filter Model CF 110 is a state of the art signal processing system that significantly reduces co-channel interference, random noise and other video errors.

It is particularly effective in reducing the 10 KHz and 20 KHz co-channel beats and restoring video synchronization even when the co-channel level is so high as to cause loss of vertical and horizontal sync in most television receivers. The Model CF 110 reduces the 10 KHz and 20 KHz co-channel beats by up to 30 dB, and other cochannel noise by up to 9 dB. Under extremely severe cochannel conditions the Model CF 110 replaces the sync pulses with stable and clean sync.

The system takes analog NTSC color video signals and converts them to digital signals. All processing is then performed on the digital signal. Adaptive notch filters are used to suppress the 10 KHz and 20 KHz beats. The video is then analyzed pixel by pixel using multidimensional correlation techniques to differentiate between wanted video and co-channel interference.
