8. Connecting DVK-300HD to SE-2800 Switcher
In other applications, the DVK-300HD Chroma Key, for example, can be connected to the SE-
2800 Switcher for switching between different live backgrounds. Live backgrounds are
captured using multiple cameras and fed into the SE-2800 switcher. Talent, in the indoor
studio, stands in front of a green background, which can be keyed out using the DVK-300HD
Chroma Key. The procedure of switching live backgrounds behind the talent is outlined as
follows:
1. First of all, double click the DVK-300HD icon into the DVK-300HD core.
2. After you have opened the DVK-300HD Utility Program, check your SW and FW versions,
and make sure they are the latest versions.
3. Click the configuration button located at the bottom right corner to open the OUTPUT
CONFIGURATION window and set Alpha Matte Preview Output to PROGRAM (PGM).
Close the window after that.
4. Check "SHOW ALPHA MATTE" in the MATTE CONTROL section.
5. Physical OUTPUT ports of the DVK-300HD will be:
a. MATTE OUT:
HDMI Out (1): Program view output (Fill Source)
SDI Out (2): Program view output (Fill Source)
b. Program Out:
SDI Out (3): MATTE output (Key Source)
