Playback Commands
Play (PL)
Command:
Plays from the current file position and continues to play until the
(address) value is reached. If no (address) is specified, play mode
continues indefinitely.
Format:
(address)PL<CR>
Response:
R<CR>
Explanation:
This command is used to begin playback from the current file
position. If an address value is included in the command, this will
define the point at which playback is to automatically pause. If a
PL command with an address is received while playback is already
in progress, playback will continue uninterrupted and the pause
address will be set as specified. If a PL command with no address
is received while playback is already in progress playback will
continue uninterrupted and any previously set pause address will
be cleared. In the event that a play command is received with an
out of range address value (i.e. – time code greater than the length
of the current file or chapter number higher than the number of
files in the playlist) the play command will not be processed and
the error code “E12” will be returned.
Examples:
0@TM13000PL<CR>
Play from the current file position until the time code reaches 1 minute 30 seconds
0 frames and then pause.
0@CH5PL<CR>
Play from the current file position until the head of chapter 5 is reached and then
pause
PL<CR>
Start playing from the current file positions and continue playback until receiving
another command. If a pause address had been set in any channel, clear
that pause address.Play (PL)
