How to execute a command remotely

[fw12]

When I execute this command on my machine:
/usr/bin/tvtime

It fires up the TV program (TVTIME).

I want to be able to do the same thing remotely via ssh. But when I do, I get this error:

Running tvtime 1.0.1.
Reading configuration from /etc/tvtime/tvtime.xml
Reading configuration from /root/.tvtime/tvtime.xml
xcommon: No DISPLAY set, so no output possible!

[1]+ Exit 1 /usr/bin/tvtime

Any suggestions on how to run tvtime remotely?
I don't have to have any output on my ssh client, I just want the program to run on the remote machine.

Thx.
