VIP (Video Improvement Processor) is a proprietary system that utilizes recursive motion adaptive techniques to achieve over 9 dB’s of noise reduction without the objectionable artifacts usually associated with other noise reducers. Independent control of luminance and chrominance noise reduction permits process optimization for many types of random noise, e.g. plain “snow”, color streaking, extraneous interference and beats.

Noise reduction levels can be adjusted manually to handle unusual conditions, or automatically as a function of noise in the input video. The AUTO noise reduction mode utilized Intelvideo’s proprietary noise sensing technology to adjust noise reduction levels, and it permits hands-off operation of the system.

The Ghost Buster circuits incorporates an adaptive equalizer DSP with embedded software that implements patented and proprietary ghost canceling algorithms using the national standard Ghost Cancellation Reference (GCR) signal transmitted in line 19 of the vertical interval of the television signal. The ghost canceling circuit operates with 11-bit filter coefficient precision, uses a 9-bit input video data, and outputs 10-bit data. As adaptive ghost equalizing can, depending on input conditions, introduce a noise penalty, the addition of Noise Reduction is ideal for a de-ghosting system.
