And the transmission bit rate of the received bitstream:
32k : 32 kbit/sec.
.
.
448k : 448 kbit/sec.
648k : 648 kbit/sec.
768k : 768 kbit/sec. (DTS only)
1411k : 1411 kbit/sec. (DTS only)
1532k : 1532 kbit/sec. (DTS only)
If only two audio channels are active in the received Dolby Digital bitstream (2/0),
the input is assumed to be Dolby ProLogic II when indicated in the bitstream. All
other signals will be interpreted by default as two-channel stereo.
In case of only two active audio channels, the user can toggle between STEREO
and Dolby ProLogic II by an additional short push on the “SURROUND MODE” key.
In this case, both the Dolby Digital and Stereo or the Dolby Digital and Dolby
ProLogic II indicators are turned on. See further information about ProLogic II below.
The normal display will return after 15 sec. from last push on “SURROUND MODE”
or by pushing the ”>VOL” key.
5.2 DTS
Generally, DTS offer the same information and possibilities as Dolby Digital. But
DTS also contains additional possibilities as described in the following.
Several new DTS formats are supported by the AV100/120:
DTS 24-bit:
The DTS encoding resolution is indicated during the DTS lock-on, second line. E.g.
768k/24 means a 768kHz transmission bit rate with 24-bit encoding resolution.
AV100/120 offers extended precision decoding of DTS 24-bitstream to take full
advantage of this increased resolution. For DTS 24-bit, this improves the dynamic
range up to 117dBA, which is fully comparable with DVD-Audio. But DTS 24-
bitstream can be played on normal DVD-Video players. Several mainstream DVD-
Video discs are already encoded with DTS 24-bit, e.g.: “Pearl Harbor”, “Jurassic
Park III”, “Moulin Rouge”, ”Gladiator”, “Lord of the Rings, SE” and “The Haunting”.
DTS ES 6.1 Discrete and DTS ES 6.1 Matrix:
Some DTS discs are encoded with a discrete centre surround channel, called “6.1
Discrete”. If such DVD discs are played, AV100/120 will indicate ES 3/3.1 at lock-on.
This means three front channels (L, C, R) and three surround channels (SL, SC,
SR) are present in the DTS stream. If “6.1 Discrete” is enabled under the
config.extended surround menu, the AV100/120 will automatically activate the
extended surround channel, SC.
Examples of DTS ES 6.1 Discrete DVD discs are “Gladiator” and “The Haunting”.
A few other DVD discs are encoded with DTS ES 6.1 Matrix, where the extended
surround channel, SC, is generated by a matrix process on the surround channels
SL and SR.
One example of a DTS ES 6.1 Matrix disc is “Terminator II, special edition”.
