Summary of Dolby Digital, Dolby Surround,
Dolby Pro Logic, and DTS
Almost every DVD disc has audio in Dolby Digital format. DTS is an optional audio format that can be added to a disc in addition to Dolby
Digital audio. Dolby Digital and DTS can store mono, stereo, and multi channel audio (usually 5.1 channels).
Every DVD player has an internal Dolby Digital decoder. The DVD 421 has a built-in 2 channel decoder which turns Dolby Digital into
standard analog stereo audio, which can be fed to most types of audio equipment using a stereo audio cable. The DVD 451 player has a
built-in 5.1 Dolby Digital decoder to provide 6 channels of analog audio via the rear panel connectors to a suitable 6 channel amplifier/ home
theatre system.
Dolby Surround is a standard audio mixing technique that adds a rear channel and a centre channel onto a 2-channel signal. A Dolby
Surround signal can be played on any stereo system, in which case the rear- and centre - channel sounds remain mixed in with the left and
right channels. When a Dolby Surround signal is played on a multi channel audio system, the extra channels are extracted to feed centre
speakers and rear speakers. The original technique of decoding Dolby Surround, called simply Dolby Surround, extracts only the rear
channel. An improved decoding technique, Dolby Pro Logic, also extracts the centre channel. Dolby Pro Logic II extracts both the centre
channel and the rear channel signals and also processes the audio channels to create more of a 3D audio environment. Dolby Surround is
independent of the storage or transmission format. In other words, a 2 - channel Dolby Surround signal can be analog audio, broadcast TV
audio, digital PCM audio, Dolby Digital, DTS, MP3, audio on a VHS tape, etc.
Unlike Dolby Surround, Dolby Digital encodes each channel independently. Dolby Digital can carry up to 5 channels (left, centre, right, left
surround, right surround) plus an omnidirectional sub-woofer (LFE - Low Frequency Effects channel). The built-in, 2-channel Dolby Digital
decoder in every DVD player handles multi channel audio by “down mixing” it to two channels using Dolby Surround. This allows the analog
stereo outputs to be connected to just about anything, including TVs and Hi Fi systems with Dolby Pro Logic capability. DVD players also
output the down mixed 2-channel Dolby Surround signal in digital PCM format, which can be connected to a digital audio receiver, most of
which can decode to Dolby Pro Logic.
The DVD 421/451 players also output the “raw” Dolby Digital signal for connection to a receiver with a built-in Dolby Digital decoder.
The DVD 421/451 players have a DTS Digital Out feature, which sends the raw DTS signal to an external receiver with a DTS decoder.
