External Control Commands
Multi-Track Jump Forward (JF)
Command:
Jumps forward in the current MPEG file or playlist by the amount specified in the <address> argument.
Format:
<address>JF<CR>
Response:
R<CR>
Explanation:
The Jump Forward command is similar to the search command accept that the address argument is interpreted relative to the current file and playlist position and the new position is always forward of the current position. In the event that a Jump Forward command is received with an out of range address value (i.e. – chapter number greater than the remaining number of files in the playlist) the Jump Forward command will not be processed and the error code “E12” will be returned.
Examples:
0@CH3JF
Jumps to the head of the file 3 places down in the playlist and then transitions to still mode. If for example file 1 is currently playing, this command would advance to the head of file 4. If there are fewer than 3 files remaining in the playlist for channel 2 error code E12 is returned and no change is made.
