Configuring a player as an L
TC receiver (slave)
A slave player can be programmed to begin playing the loaded clip or playlist when it
receives a particular LTC timestamp. A different LTC timestamp can be programmed for each
clip in a playlist.
Figure

shows using the Edit Playlist Properties dialog box to receive an LTC (
a
), start
the video 10 seconds after the receipt (a 10-second delay) (
b
), and run the LTC on until
01:05:00:00 (
c
). If the video presentation is 4 minutes and 30 seconds, this results in a
30-second post-roll period.

The file will run until a StopAt command halts the player and the display goes black after
5 minutes (01:05:00:00).
Besides setting the player as a slave and (if applicable) setting
Play
At
and
Start
At
times,
you need to consider, when configuring a slave player, whether to operate that player in
chase or trigger mode:
•
Chase Mode —
The media player tracks (stays in sync with) the in-coming LTC.
•
Trigger Mode —
The media player begins playback at a specific LTC timestamp value,
but continues playing without any further reference to the incoming LTC.
Chase or trigger can be selected using any of the following:
•
The front panel control (see “
Video submenu
“ in the “Operation” section)
•
The HTML setup dialog boxes (see “
Video mode setup dialog box
“ in the “HTML
Operation” section and figure
73
)
•
The
SetTimecodeOpMode
MSVPP command (see “
Applicable MSVPP commands
”).
