Video Waveshaper

HSY to YUV/RGB colorspace conversion, complex waveshaping and color manipulation

Colorspace Mapper is a complex color mixing and processing tool based on the conversion from HSY (Hue/Saturation/Brightness) to YUV (Brightness/Red-Y/Blue-Y) and RGB (Red/Green/Blue) triple color-spaces. It includes several internal voltage controlled amplifiers, polar-to-cartesian coordinate waveshapers, input processors and summing circuits. All signal paths are suitable for wide bandwidth, video-rate processing.

External inputs may be patched into the HSY inputs on the front panel. These inputs are then processed by their associated gain/inversion controls and summed with their associated bias controls. The resulting HSY signals are then fed into the HSY-to-YUV conversion circuitry and output to the YUV jacks. The YUV signals are simultaneously fed into a YUV-to-RGB conversion matrix and output to the RGB output jacks. Very powerful colorization and conversion can occur by remapping external signals to these alternate colorspaces. For example, a black and white video fed into the Hue input, will cause the output colorspace to achieve a hue rotation, or thermal imaging type of effect.

The Hue-to-UV waveshaper has a depth of 720 degrees (2 full rotations.)
