Downstream Keys

Next to the 11-input main switcher is the downstream key (DSK) block. It can be used to add
images or text to the broadcast signal. DSK signal may come from any virtual player that
displays media (1 or 2), bitmaps (1 or 2), or text (1 or 2). It may also come from the camera
inputs. For the DSK function to operate properly, the media provided to DSK must contain
transparent areas. In this way, they will be overlaid on the main signal. Media without
transparent areas is not recommended to be used in DSK as they would completely cover the
broadcast image with their contents.
