DSK CHANNELS
Figure 8
TriCaster’s DSK layers support dual-channel downstream keyed (or alpha) overlays. Assign any
Switcher source or a dedicated Frame Buffer to either channel. DSK channels can be displayed in
tandem or independently, or swapped – again, with independent custom transitions.
You might use the Graphics or DDR modules to overlay title pages, including scrolls, crawls and
lower-thirds – or delegate a Camera input or Network source as an overlay (using the Switcher’s
Utility row ). Alternatively, use the Frame Buffer feature to assign a specific title or image to any
overlay channel, and even update it in realtime over a network using external graphics or titling
software.
Independent Crop , Position, 3D Rotation , and Scale controls for each DSK channel permit you (for
example) to configure two live sources as ‘Picture in Picture’ elements using the DSK channels,
freely switching them on and off (with or without individual custom effects), with or without
changing the BKGD (Background) video layer using the Program and Preview rows on the
Switcher .
