WD TV Live SMP audio optical out to sony hi fi System question

I have a Sony MHC-GZR5D Mini Hi Fi System ( http://www.sony.co.in/product/mhc-gzr5d/specs) and it has an optical audio port at the back ( http://support.sony-asia.com.edgesuite.net/consumer/IM/3296435111.pdf page 20). Its written “DVD Optical Out” under the port

Question is, is it possible to connect WD TV Live SMP to my hi fi system using an optical audio cable and play WD TV Live SMP audio through my hi fi system?

Does optical port has separate input output concept? Aren’t they bidirectional like HDMI ports?

Thanks,
Simon Mandy

No.  Optical is unidirectional.

HDMI is unidrectional as well.  It’s not bidirectional…
