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.
