15 DSKS (OVERLAYS)
3Play offers two fully independent DSK (Downstream Keyer)
overlay channels – one for each primary output. Both provide
integral alpha channel support and independent Positioner controls
(including edge cropping). Video and graphics overlays can be
scaled and cropped, and placed anywhere within the video frame.
Overlay channels can be used creatively to layer video sources for
compelling highlights and much, much more. The combined power
of overlay layers and replay open up endless new opportunities.
15.1 OVERVIEW
Conventional replay systems are unable to show
two synchronized angles of an event on a single
output.
Not only does 3Play let you overlay an alternate,
fully synchronized angle of instant slow motion
replay on another and send it to output, you can
also overlay live video onto another source (live or
recorded) or vice versa.

DSK allow you, for example, to continue to display live
action while playing highlights, show replays or ads in
an insert, or display two live video angles at once.
The combinations are almost limitless, providing incredible
flexibility to design workflow solutions tailored to very specific
requirements previously requiring multiple systems.
Enabling the DSK display is as simple as clicking the DSK A or DSK B button.
