Digital Impulse Noise Eliminator Model INR 2000
Digital Impulse Noise Eliminator Model INR 2000
Description - PDF Spec Sheet

lntelvideo's Digital Digital Impulse Noise Eliminator Model INR 2000 is an advanced, next generation implementation of the very popular Impulse Noise Reducer Model INRes. It is a state of the art signal processing system that essentially removes all electrical or ignition-type impulse noise from NTSC color television signals with practically no picture quality penalties. Like the Model INRes, the Model INR 2000 is also very effective in detecting and correcting satellite or FM link threshold noise that normally appears as "sparkles". It is as effective as the most advanced median filter but without the undesirable artifacts introduced by median filters.

The performance of the Model INR 2000 has been significantly improved with the addition of two new modes of operation, SPT1 and SPT2 (for sports programming). In these modes, the advanced complex logic of the INR 2000 is capable of differentiating between electrical impulse noise and fast moving video details like panned football field markings or a moving golf ball, which normally have the same correlative characteristics as impulse noise. In the INRes, those markings could be masked. In the INR 2000, only truly electrical noise is removed. Optional random noise reduction is also available (see the Model HQ2000).

Aside from the standard analog-to-digital and digital to analog conversion operations, the system signal processing is all digital. Every video pixel is analyzed and a differentiation between video and noise is made based on the statistical characterstics of unwanted noise and errors. Sophisticated circuits are used to analyze the video signal and serach for impulse noise and dropout errors using multidimensional correlation techniques. To differentiate between impulse noise and moving video details, motion is also detected using a number of video frames for temporal correlation detection. When the circuits determine that a particular video pixel has noise perturbation or is in error, and the motion circuits determine that there is no motion in the vicinity of the error, that pixel is replaced with a value predicted from spatio-temporal neighboring pixels. All signal processing is performed on the composite color signal, thus avoiding the introduction of video impairments due to color decoding and re-encoding.

The unit is fully self contained. It takes a baseband NTSC color video signal at 1 volt peak to peak and it outputs a processed NTSC color video signal at the same level as the input. Hardwired bypass occurs in the event of power loss.
