DVD Player Haxoring, VFD display.

Im still trying to figure this thing out. I could use some help with connecting this to an arduino, and with the software to control it.

Im guessing this thing has a driver built into it, with shift registers or something to accept serial data, in some form.

This is what I have to connect to:
INIR
VCC
Data In
CLK
STB
Data Out

INIR I think is data from the IR receiver. I can ignore this for now.

VCC is voltage, Im guessing 5v.

Data in, my guess is like DS on a shift register.
CLK Im guessing is the clock pin
STB ???
Data Out, maybe this one is the DS? and I should ignore data in ?

I just dont know what to try, or where to begin.
