User manual GRASS VALLEY 8981NR DATASHEET

[. . . ] [. . . ] This module incorporates two different noise reduction methods that are targeted at different sources of noise. A recursive filter is effective for low levels of wide-band (random) variations that have no frame-to-frame correlation, and a horizontal median filter is very effective for impulse noise. Typical applications include reduction of random noise generated during analog transmission or digital processing. Signals from various sources with varying amounts of noise resulting from poor transmission and processing will greatly benefit from using this product by reducing the bandwidth required later during the MPEG compression process. 8900V-R J1 J2 Video Output J3 J4 Video Output Not Used Video Input Not Used J5 J6 Not Used Not Used Not Used J7 J8 J9 J10 EDH Detection SDI Input LED Noise Filters Test Generators SDI Output Framestore Control Local Controls Microprocessor Ethernet Specifications Supported Frame Types GeckoFlex with 8900V-R GeckoFlex Video rear module, Gecko video frames: 8900TX-V, 8900TF-V, 8900TFN-V Ordering Information Environmental Conditions Operating ambient temperature (frame): 0° to 45°C Operating humidity range: 0% to 90% noncondensing This module can be mounted in a GeckoFlex frame when ordered with the 8900V-R GeckoFlex Video rear module.
