Signal Conversion is a feature that enables a field monitor to output a video signal in a format that’s different from the format that was input.
For example, if you connect the HDMI output of an HDSLR camera to the HDMI input on an on-camera monitor with Signal Conversion, the monitor will output a duplicate of the camera’s HDMI feed on a jack of a different format, such as SDI.
This is a useful feature because HDSLR cameras don’t have SDI ports. Being able to send the feed from an HDSLR camera up to 300 feet away on an SDI port to a field monitor with an SDI input is impossible without Signal Conversion.
