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)
