The device is designed to display alphanumerical characters, raster graphics and vector graphics on the image from camera. The SG-55HD device is nothing more as the OSD-50HD equipped with a connector housing, stabilizer and service buttons.

From the video signal the SG-55HD operates as a loop-through device, equipped with signal input and output. The device control protocol can be found in the technical documentation.  In addition the SG-55HD can work in character terminal mode and  display all character strings
