Test Signal Generator
Using the TSG front panel button, the MVPHD-24 produces various test signals to assist the operator with
level adjustments, color correction, color temperature, sizing the image, and adjusting the camera’s shutter
phase. Up to eight user created full-frame test signals may be added to the list of TSG signals. Test signals
are produced on the input path allowing it to be resized with the scaler.
Scaler: Size and Centering Controls
The scaler is used to automatically change the input resolution to match the output. In addition, Size and
Centering controls allow the vertical and horizontal size of the picture as well as its position to be adjusted.
This provides easy calibration of monitors which were not setup for 24 frame playback. These controls can
also be used for effects by shrinking or stretching the picture, or making non-standard aspect ratios. They can
also be used to achieve increased vertical blanking time. This would allow for shutter angles greater than 180
degrees.
Color Correction
The MVPHD-24 provides color correction controls in the RGB color space to adjust output signals.
Color Temperature
Controls are provided for adjusting the color temperature of the picture to match the ambient lighting in the
scene being filmed. The color temperature controls use the component X-Y color space. This allows various
temperatures to be produced without desaturating the color image. The MVPHD-24 has menu controls for
creating custom color temperatures, as well as presets for 3200, 4800, and 5600 degrees.
