It's not an option, it's an alternate way to specify the signal to send.

kill -19 ... => stop the process
kill -18 ... => continue the process

kill -SIGSTOP ...
kill -SIGCONT ...

kill -STOP ...
kill -CONT ...

All the above are equivalent forms for the same command.

We also have the equivalent kill -s 19|SIGSTOP|STOP

Same for the other signals, e.g.:
- kill -s 1
- kill -1
- kill -SIGHUP
- kill -HUP

True is that the standard man page is a bit obscure on this subject...

Not specifically what you asked, but VNC (tightVNC, etc.) provides a
stateful X session (apps, desktop, etc). I have only just started playing
with VNC, but the most simple option "leaves" the audio at the remote
device. That may, or not, be what you want MPlayer to do.

For text console purposes, you might look at the 'screen'
utility. It lets you detach a running job from one console (or
terminal window) and reconnect to it later. You would probably
have to ssh to the machine on which mplayer is actually running,
but that's not hard.

Reread carefully, the bit about a different console, in any case
the answer was given days ago.
