Local-to-Remote Timing
In Local-to-Remote Timing , local video is synchronized to incoming decompressed video—
which normally has long GOP encoding, and a very long propagation delay resulting from
the MPEG encode/decode process. The X100 can overcome these synchronization problems
by aligning local content with the incoming remote content so that master control
switching is frame-accurate (
Figure 3-4 ).
Figure 3-4 Local-To-Remote Timing
One X100OPT-SK-PD software key is required for Local-to-Remote Timing. Follow these
steps to configure the X100 for this function:
1 At Video Input Control and Status > Input Routing , feed the local program content into
the primary channel ( Proc Ch 1 Source ).
2 Feed the remote program content (long GOP MPEG decoded signal) to the secondary
channel (
Proc Ch 2 Source ).
3 Adjust the slider at Video Output and Routing > Program Delay > Delay Channel 1
until the output local content and the remote content are aligned.
Output channel 1 now contains the timed local program content and channel 2 contains
the timed remote program content.
