Crystal Vision ViPA video proc-amp launched

Crystal Vision has added a video proc-amp to its modular interface range.
The 10 bit ViPA allows flexible independent adjustments of a digital signal image in the YUV colour space and offers an impressive set of tools for a processing amplifier at this price level. Tools provided by the 100 mm x 266 mm board to fine tune the YUV channels include independent lift to boost or reduce the black level for Y or the colour difference offset for U and V, independent gain to amplify or reduce the Y, U and V signals, and overall gain and lift to adjust the three channels together. Hue phase adjustment allows correction of NTSC colour shift errors on the U and V channels. Independent YUV adjustable soft clipping ensures colours do not overrun the CCIR601 specification by forcing the picture to remain within the valid dynamic signal range, while being able to choose the severity of the clipping level avoids the unpleasant picture artefacts caused by hard clipping. Horizontal picture position correction, luminance and chrominance timing correction in 148ns steps and adjustable horizontal and vertical cropping to clean up picture edges complete the set. If no correction is required, processing is completely transparent, preserving signal integrity.
ViPA passes all auxiliary data without modification with any adjustments affecting the active picture only. It offers ten user memories to store commonly used adjustments and has GPI output indication of clipping.
ViPA is available in two versions. ViPA102 has one input and two outputs, while the dual ViPA204 - useful for limited space applications - has two inputs with two outputs of each. Both versions should be used with the RM01 frame rear module. Sharing the standard frames system (2U, 1U and desk top box) ViPA can be easily integrated with the full Crystal Vision product range. The flexible control options include active frame front panel, remote panel and the Statesman PC Control System.
Applications include correcting errors caused by methods of transmission and storage or errors caused by colour space and A to D conversions.
