Executing a multimedia file in one instance of VLC

Hi all,
I am completely new to applescript, and I need some help with a script that will probably be silly for many of you.
My problem is the following: I need to engineer a script to let VLC play a multimedia file continuously every minute. If VLC is not running, the script should start it and get it to play the file. In case VLC is already running, on the other hand, the file should be enqueued so as to be played as soon as the currently played file terminates.
Any idea how to do it?

Many thanks in advance.
