Broadcast Pix
V3.0
1.9 Input Timing
Reference
The Broadcast Pix Switcher can auto-detect external reference, either analog blackburst
or Tri-Level sync in these formats: 480i29.97 (NTSC), 720p59.94, 1080i59.94,
1080p29.97, 1080PsF29.97, 576i25 (PAL), 720p50, 1080i50, 1080p25, 1080PsF25
.
If no reference is connected, the Mica Switcher can generate internal sync. In this mode
the Ref I/O connection can be set to output blackburst to external equipment.
The Ref I/O LED on the switcher will illuminate green whenever there is a reference
signal, internal or external.
To output genlock:
1.
In BPswitcher, click on
Setup
and a
drop down window will appear, then select
System Settings…
as shown on the right.
The System Settings window will appear.
2.
In System Settings window, click on the
Video
Tab, which will bring up the
various video settings.
3.
Under the Options section, place a check
mark next to
Output Genlock
, as shown
on the right.
4.
Click on the
OK
button to apply the
settings and to close the System
Settings window.
Synchronous Inputs
All Mica systems work well with all video inputs that accept a reference input for genlock,
including broadcast cameras, tape recorders, servers, etc. The timing window for
genlocked sources is +/- 10 lines. The delay through the Mica system on synchronous
sources is 1 frame, even if the image is inside a DVE box (picture in picture).
A-synchronous Inputs
The system will also accept and self time asynchronous sources, such as a DVD player.
All 8 live inputs accept asynchronous inputs. The delay through the Mica system on
asynchronous sources is up to 2 frames.
