Black burst generator provides the user with 2 precision blackburst and 2 SMPTE color bar outputs. The unit automatically selects between NTSC or PAL in the Genlock mode according to input reference. It defaults to the selected standard in the free run mode. It takes advantage of the latest FPGA technology to provide the highest performance for color bar, black burst, or to pattern flash. The color bar patterns are SMPTE for NTSC and 75% for PAL. There are two pairs of independently selectable outputs.
