I bought an LG Soundbar to get better audio on my TV. I installed it; and it seems to work. But I am confused by the manual's descrption of a so-called optical link.

 

It appears from the manual that the TV audio signal is, somehow, converted to an optical signal within my TV set. And that that optical signal is carried to the Soundbar, where it is reconverted back to the improved audio that I hear?

 

Is that reading of the manual correct; or (probably) not? Whyever does the process go through those digital/optical conversions?

 

Can some patient GtGer please straighten me out? Thanks. …... batpark

Model number would help.

This is a good explanation on how it works.

Peterm: Thanks for forwarding the reference. I will try to understand it. It is not clear to me just what  (why) the optical link was used but it is apparently so.  ... batpark

In some ways it is the same as your internet.

It used to come down copper wires but is now sent down optical fiber.

The same with sound.

It is now sent down optical fiber.

With optical fiber you don't have the same kind of problems as copper wires.

E.G corrosion. and reliability and its resistance to interference.
