External Control Commands
181
Pause (PA)
Pauses the designated channel(s) at the current file position and
blacks out the picture.
Syntax
PA<CR>
Response
R<CR>
Remarks
The PA command will pause playback, Scan Reverse or Scan
Forward. While having no visible effect on screen, it should also
transition from Stop to Pause holding on frame 1 of the first file of
the playlist. This is simply for compatibility with LDV devices
which can use PA as a means of spinning up the disc without
actually beginning playback. By transitioning from Stop to Pause
the media player will give the control system the expected
response if a status request is made later. In all cases, PA results in
the target channel(s) being blacked out until another command is
received. The Blackout will only remain in effect for as long as the
channel(s) is in Pause mode. Any command which transitions the
channel(s) out of Pause mode will also unmute the video on the
specified channel(s)
Examples
PA<CR>
Pauses all channels on the media player and blacks out the
video outputs.
1@PA<CR>
Pauses channel 1 on the media player and blacks out the
channel 1 video output.
