Creating & Configuring Transport Stream Sources
Freeze on LOS—When enabled, causes the source to hold the last good frame if the
signal is lost. When disabled, LOS causes the LOS Video Test Pattern to be displayed. For
details, see
LOS Video Test Pattern—Select the test pattern to display during LOS.
Use Inverse Telecine—Does not apply in Capture, because no frame-rate conversion is
applied. Do not enable this control.
TS over RTP—Enable to receive transport streams wrapped in RTP packets.
Cisco ID3 (Advanced mode only—see
SCTE-104 information to be converted to ID3 for deliver to the Capture action.
source associated with the incoming frames it can drift over time and get out of
sync with the incoming stream. When a drift of one second is reached the timecode
being added to the file is re-synced to the system's Computer Clock time. This
means there may be a discontinuity in the file's timecode at the point where the re-
sync occurred. Enabling Free Run Timecode when Compensate for Computer Clock
Drift is enabled has no effect on the process described here.
When Compensate for Computer Clock Drift is Disabled
The source process uses the Computer Clock time without compensating for drift.
Over time the timecode may drift several seconds compared to the 'real' time. For
example—if a recording is 6 hours long the Computer Clock drift might be many
seconds by the end of the 6 hour recording. If no frames were dropped the time-
code in the output file is contiguous from start to finish.
