Introduction
MPEG Surround
MPEG Surround is the preferred audio format for DVD in PAL
territories, and along with Dolby Digital is a contender as the
standard for music and performance videos on DVD worldwide.
In addition, it is widely available in US satellite broadcasts.
THX versions
THX versions of Dolby Digital, MPEG Surround, and DTS are
provided to give a better match between the original soundtrack
and typical domestic listening conditions.
Music versions
Music versions of Dolby Digital, MPEG Surround, and DTS are
provided with a lower LFE level, to match the bass levels in
music CDs.
MLP (MLP version only)
MLP (Meridian Lossless Packing) is the standard format for
music on DVD. It allows multiple audio channels, of up to
192kHz 24-bit quality, to be stored on a DVD without losing any
information. It can also be used to store four-channel audio on a
standard CD without any loss of quality.
Multi-channel sources encoded onto
two channels
Several systems have been developed for encoding multi-
channel sources onto a standard two-channel analogue signal
so that they can be reproduced by a conventional stereo
system, or decoded with special equipment for multi-channel
reproduction. The 565 Digital Surround Processor provides
decoding of the two most important of these, Ambisonic and
Dolby Surround. Although the channel separation cannot be as
good as with the digital multi-channel formats, the 565 produces
excellent results with these formats.
Pro Logic
The Pro Logic preset is recommended for decoding Dolby
Surround encoded video and LaserDisc soundtracks, and films
on television. Such materials are usually identified by a Dolby
Surround symbol on the packaging, or displayed on the film
before the programme.
