Adapter Cable For iPod Plug and HDMI Port?

My treadmill has a TV screen and an iPod/iPhone cable connected to it.
I'm guessing that the cable has a 30-pin plug (male).

I would like to connect a laptop (with an HDMI port) to this
iPod/iPhone cable and stream programs to the treadmill's TV screen.

I don't seem to be able to find a cable adapter having at one end a
30-pin (female) iPod/iPhone plug and an HDMI (male) plug at the other
end.

Is there such cable? What are other options to reach the goal?

With the difficulty of finding the proper adapter, I think it might be
easier to pick up a used iPad and stream your programs through it :-) Just
an idea . . .
