Enable Checkbox
The ‘Enable’ checkbox connects the Io IP to the network address specified by all
the matched output parameters. Any time a parameter is changed, the output
should be re-enabled.
DS Keyer Screen
Io IP has a hardware-based downstream keyer that is ideal for putting logos,
“bugs” or other video material with an alpha channel on top of video being
played out or printed to tape. A typical application would be putting a television
station’s call letters or channel over program video content. Keyed video can
be from the Io IP’s internal Frame Buffer (from storage, Video In, etc.) or from a
graphics file that has an alpha channel (PhotoShop etc.).
Settings in the DS Keyer Screen provide control over how the keyer operates and
whether it’s turned on or off.
