BOB-4 OSD

DECADE ENGINEERING BOB-4 OSD Video Information Overlay Module

The is decades fourth generation low cost video information overlay module, available in a rugged 2x20 header connector format with industrial temperature specs as well as the original 30pin SIMM format. BOB-4 lets your microcontroller or PC display text and vector graphics on standard TV monitors. With large user definable character sets, BOB-4 also supports bitmap graphics and multiple languages. BOB-4 generates background video on board, or automatically genlocks to your video source and super imposes characters over the image. Printable characters and commands drive BOB-4 through fast SPI or RS232 style data links, much like a serial terminal or printer. BOB-4 links directly to most microcontroller chips and modules. NTSC and PAL video standards are supported in a single hardware version.
