Dolby Digital
Plus
1.0 - 7.1+ Discrete
Audio codec which allows for higher
bitrates, 7.1 channels or more
(currently limited by HD DVD,
Blu-ray disc
™
standards), while still
remaining compatible with older
5.1 systems. e codec was designed
based on Dolby Digital but provides
the necessary versatility going into the
future.
DolbyTrueHD 1.0 - 7.1+ Discrete
is is a true next-generation
surround mode where the audio
is bit-for-bit identical to the high-
resolution studio master audio.
Similarly to Dolby Digital Plus
the track contains a 5.1 core for
backwards compatibility.

LPCM 2.0 - 7.1 Discrete
is uncompressed digital
representation of analog audio was
initially developed as the Redbook
standard format for stereo CD audio
and DVD-A 5.1 multichannel audio.
Depending on the source material,
this high resolution format is capable
of outputting sample rate resolutions
of up to 24 bit/192kHz.
post-processing e rst thing the SSP Surround Sound Processor does is recover the various
channels delivered by your source with accuracy and delity. is might be a
single-channelmonosignal,aDolbyTrueHDsoundtrackwith7.1channels,or
anything in between. e signal may have been delivered via satellite receiver,
cable set-top box, DVD, or even downloaded from the Internet.
Once the SSP has decoded the selected signal, you can then choose to send it
to the output unchanged, or you can add further processing, often called post-
processing. is kind of processing is particularly useful for utilizing additional
surround speakers with limited audio track sources. For instance, processing a
2-channel stereo source with Dolby Pro Logic IIx generates a 7.1-channel output
so that you can enjoy the audio source in full surround sound.
