Auto blank In Auto Blank mode, the FS2 automatically detects presence or absence of line 21 caption
data on the SD input. If no line 21 caption is present, the FS2 passes the video unaltered.
If line 21 data is detected, the FS2 copies the data, blanks line 21, and reinserts translated
captioning on the transformed HD output if parameter 18 Caption Xlator is On. If the
Caption Translator is Off, the HD output will not contain captioning. This is the setting to
use if your SD input video sometimes contains captions and other times does not, or if
you are uncertain which setting to use.I
Test Pattern
This parameter selects the video source for the Test Pattern Generator. The pattern
generator is turned off and on using Output parameter 3 Video Output mode.
21 Test Pattern Video
Freeze
This parameter tells the FS2 to freeze the current video frame on all outputs. This may be
useful either for testing or in case of loss of the input source.
22 Freeze Output
The freeze feature can be controlled not only by the front-panel and web browser
interface, but also by a GPI input. When a GPI input is causing the freeze condition, the
EXT lamp will be lit on the front-panel.
AUDIO 1 and AUDIO 2 Menu Groups
The Audio Menus control the FS2’s audio routing and signal processing. Because the
selections for the video processors are identical, both are described here.
