Pretty much.
You should check the data stream on a scope though just to see what the logic levels are and assuming the bits are switching between 0V and 3V then yes, supply 3.3V and ground and the data line. Remember the 100nF cap on the transmitter power - real close - thats important.
You may want to take the feed from before the S/PDIF output filter/transformer for sharper edges, that'll need some reverse engineering of the PCB and if you have to run a wire longer than a couple of inches, I'd put a 33ohm resistor in series with the transmitter data in, just to terminate the line.
Possible snafus are:
inverted data
5V (or other) logic levels
bipolar data output on RCA (swinging ±3V)
might need an extra switching tranny to fix these.
