Dolby Pro Logic IIx
Mode Group
An expansion of Dolby Pro Logic II that adds a surround back channel
which may be played through one or two surround back speakers. The
Dolby Pro Logic IIx modes may be selected not only with Dolby Digital
bitstreams, but thanks to the AVR 760/AVR 660’s post-processor, they
may also be used with some DTS bitstreams to add a surround back
channel to 5.1 modes.

DTS-HD DTS-HD is a new high-definition audio format that complements the
high-definition video found on Blu-ray Disc and HD-DVD discs. It is
transmitted using a DTS core with high-resolution extensions. Even
when only DTS 5.1 surround sound is desired (or available, if the
multizone system is in use), the higher capacity of high-resolution discs
serves up DTS at twice the bit rate used on DVD-Video discs.
