Controls by frame or timeControls by frame or time
When using serial control with a laserdisc, the playback starting position can be
specified by frame or timecode of the disk.
In HDMA-4000, create a ContentFrame.idx file where content frames are registered,
or a ContentTime.idx file where timecodes are registered and place these in the
[serial] folder, to enable the supported commands, FR and TM, thus enabling search
and playback in accordance with the contents’ frame or timecode.
* If the contents registered in the ContentFrame.idx or ContentTime.idx files do not exist, all serial
controls based on the frame/timecode will return errors.
- FR command
In order to use the FR command, create a ContentFrame.idx file in the [serial]
folder.
The descriptions in the ContentFrame.idx file are as follows:
Frame number [TAB] File name,0
* [TAB] represents a tab character.
* Always add the ,0 characters to the end of a file name.
For example, to play multiple contents back using serial controls, in the event
that the contents are sequential frames on a laserdisc, use the following
descriptions:
FR # Changes to frame specification mode.
1SE # Displays 1 frame.
1000PL # Plays until frame 1000 and stops.
1001SE # Displays frame 1001.
2000PL # Plays until frame 2000 and stops.
2501SE # Displays frame 2501.
2800PL # Plays until frame 2800 and stops.
