SERIAL DIGITAL KEYER / MIXER
The Microvideo Digital Keyer allows captions or logos to be added to a background picture. They can be faded in and
out with transitions initiated by GPI, RS232 or front panel. Front panel or Remote Control gives access to key
processing with control of gain and offset. A mix function allows a fade between 2 sources so that it can also be used
as a simple two channel fader. The Keyer is transparent to embedded audio and other ancillary data. A preview output
allows you to view the effect of adding the caption or logo before actually keying onto the main program output. The
keyer module is housed in a 1U rack frame and may have additional modules plugged in. This includes a PAL/NTSC
coder for monitoring purposes or an analogue to digital converter with RGB(YUV) and Key input. This is usual for
keying the output of an analogue character generator onto an SDV signal.
