result, when DD+ signal is output from
the set-top-box, its quality is better than
that of classical DD despite the lower
bandwidth required for transmission.
Compatibility
Transmissions in Dolby Digital Plus
require a set-top-box (or “a receiver” as
we call it in TELE-satellite reports) to be
equipped with a DD+ decoder, otherwise
you will hear nothing. French viewers of
TNT HD multiplex R5 must use new DD+
compatible set-top-boxes.
But what about the output? Do you
need to upgrade to the latest A/V
receiver? No, not necessarily. If you have
one which is DD+ compliant, that’s great.

So far 7.1 A/V receivers are rare, but
this is the future of top class audio. Will
they be used only in Blu-ray Discs or
also in digital TV? It is hard to say today.
Presently, the main reason to introduce
Dolby Digital Plus in digital TV is the need
to save the bandwidth. But who knows,
