Configuring a player as an LTC 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 72 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”).
