Product Overview

The Rack mounted and tiltable V-R72DP-2C represents leading edge technology in LCD imaging for broadcast and professional video applications featuring High Resolution, 1.2 megapixel, TFT screens with completely digital signal processing.

NTSC and PAL composite video standards and signal types are accepted and displayed on each screen of this model. Analog signals are digitized using an advanced 10 bit process on each signal path with 4x over sampling and adaptive 5 line comb fi lter with exacting color space conversion. All video formats are scaled to fi t on screen in the highest resolution using a state of the art LSI that incorporates 4x4 pixel interpolations with precision Gamma correction to produce the best images available.
