OSD-KB: On-screen display id overlay board with PS/2 keyboard interface

$119.00

Screenshot

Description:

OSD-KB is a standalone on-screen display board that overlays user defined text, entered through a standard PS/2 keyboard, onto an incoming NTSC or optional PAL video source.  Every position on the 28 column by 11 row screen (308 characters total) can contain a user typed character.  All information is stored in non-volatile eeprom memory so even with loss of power OSD-KB retains all screen information. NTSC and PAL versions available.

 

Special keyboard functions include an overlay or self generated screen mode selection, character blink toggle, character background frame toggle, character color selection (self-gen mode only),  background screen color selection (self-gen mode only), full screen clearing, and a translucent mode toggle.  Translucent mode is a unique feature that allows live video to pass through the text like the major networks do with their logos.

 

The on-board jumpers select the text triggering method.  The text triggering method defines when the text screen is displayed.  The text triggering methods include an always on, only display when jumper pulled to ground, and display based on a timer (every 10 minutes on for 15 seconds.)
