Step 2: Choose a Synchronization Method
Click the
Sync Option
arrow and then click the method you want to use to synchronize
the SDI output:
•
Internal:
The SDI output will be synchronized with the timing chosen from the SDI
signal format list.
•
Genlock:
The SDI output will be synchronized with the external sync signal.
•
Frame Lock:
The SDI output will be synchronized with the timing chosen from the SDI
signal format list.
This list is limited to timings that can be synchronized with the detected external sync
signal.
For more information regarding genlock and frame lock, see the section
the SDI Output to an External Source” on page 19
Step 3: Specify the SDI Signal Format
The SDI signal format controls the video resolution, field rate, and SMPTE signalling
standard for the outgoing video stream. Your options for this setting depend on which
Sync option you chose in the previous step.
Internal
If you chose internal synchronization, then click the
SDI signal format
arrow and click
the signal format you want to use.
Genlock
If you chose genlock synchronization, the sync source controls the SDI signal format. The
list box will be grayed out, preventing you from choosing another format.
Frame Lock
If you chose frame lock synchronization, only those modes that are compatible with the
detected sync signal will appear in the SDI signal format list.
Click the
SDI signal format
arrow and then click the signal format you want to use.
Step 4: Specify the SDI Output Format
The SDI output format controls the color model, data packing, and alpha or z components
in the outgoing video stream.
Click the
SDI output format
arrow and then click the color format you want to use.
