The BG-7 (single pattern output plus 6 black burst outputs) are video multi-pattern generators with the ability for the user to import a graphics file and overlay that image on the pattern output. Applications include source ID in studio and mobile applications. A 24-bit full color graphic is created with any paint program and loaded into the BG-7 via a front-panel USB 2.0 port. Once stored in the unit, the graphic image is overlaid on the pattern output. There is an On/Off switch to control the insertion of the image. The image can be a digital photo, logo, station call letters, etc. Size is 720x480 for NTSC, 720x578 for PAL. File format is BMP. The BG-3 and BG-7 are dual standard, NTSC/PAL, jumper selectable (front panel switch optional.) They offer full frame image support in both NTSC and PAL.
