Description:
OSD-ID+™ is a single channel, standalone static character and graphic composite video overlay circuit. This user programmable device can display up to 30 columns by 12 rows (NTSC) or 15 rows (PAL) of text and imported graphics such as logos directly onto an incoming composite video source. If no video input source is available then OSD-ID+™ overlays text and graphics onto a self-generated background screen. The overlay can be configured to always display, appear on a configurable timer (e.g. every 10 minutes for 30 seconds), or appear on an external button press.
Included with OSD-ID+™ is font editing software. OSD-ID+™ firmware upgrades are supported via a PC connection.
