Chapter 8 – Adding Custom Test
Signals
Introduction
The MVPHD-24 has eight FLASH Image buffers available for use as customer created test signals. The contents of
these TSG buffers are stored in non-volatile FLASH memory and retained even when power is removed from the unit.
To load a custom TSG image, a Custom Key is required. Once a TSG buffer has been loaded, it will appear in the list
of available test signals.
Custom Key
In order to access menus for loading custom TSG images, a Custom Key is required. Each purchaser of the
MVPHD-24 is provided with a unique Custom Key which is assigned to the serial number or group of serial numbers
registered to that customer. The Custom Key is a security feature that prevents field operators or rental customers
from altering the custom test signals without having the correct key.
The Custom Key is a special file (“
Customize-xxxxxx.MVP
”) which must be located on the root directory of an
SD/MMC card. When the SD/MMC card containing the Custom Key file is installed on the front panel of the
MVPHD-24, additional menus will become available to load custom TSG images.
Custom TSG Images
The Custom TSG buffers can hold full-frame full-color images up to 1080p resolution. These images can be captured
from the output image of the MVPHD-24, or loaded from the SD/MMC Card.
Custom TSG Signal Names
The Custom TSG signal name that appears in the list of test signals is either specified when capturing the output
image of the MVPHD-24, or is based on the image’s filename when loaded from the SD/MMC Card.
Capturing Custom TSG Images
The output image of the MVPHD-24 can be captured and saved as a Custom test signal. This allows the operator to
use any input as the source material. The MVPHD-24 uses a high performance scaler when converting from the
input’s format, to the output’s format. The operator should keep this in mind when capturing the output image. The
resolution of the stored test signal will be determined by the MVPHD-24’s Output Format setting. For best quality,
it is recommended that the Output Format is either set to the same resolution as the input source, or that it is set to the
maximum resolution of 1080p.
To capture images to the Custom TSG buffers, a SD/MMC Card must be installed on the front panel which contains
the Custom Key (located in the root directory).
To access Custom TSG menus, press the TSG button while holding down the MENU ENABLE (also labeled PREV)
button. This will open the TSG control menus. Pressing NEXT or PREV (previous) will step through the TSG control
menus.
