DivX
®
Digital video technology created by
DivX, Inc. Videos encoded with DivX
technology are among the highest quality
with a relatively small file size.
Dolby Digital
This sound format for movie theaters is
more advanced than Dolby Surround Pro
Logic. In this format, the surround
speakers output stereo sound with an
expanded frequency range and a
subwoofer channel for deep bass is
independently provided. This format is
also called “5.1” because the subwoofer
channel is counted as 0.1 channel (since it
functions only when a deep bass effect is
needed). All six channels in this format
are recorded separately to realize superior
channel separation. Furthermore, since all
the signals are processed digitally, less
signal degradation occurs.
Dolby Pro Logic II
This technology converts 2 channel stereo
recorded audio into 5.1 channels for
playback. There is a MOVIE mode for
movies and MUSIC mode for stereo
sources such as music. Old movies
encoded in traditional stereo format can
be enhanced with 5.1 channel surround
sound.
Movie mode
The Movie mode is for use with stereo
television shows and all the programs
encoded in Dolby Surround. The result is
enhanced sound field directionality that
approaches the quality of discrete 5.1-
channel sound.
Music mode
The Music mode is for use with any stereo
music recordings, and provides a wide
and deep sound space.
Dolby Surround Pro Logic
As one method of Dolby Surround
decoding, Dolby Surround Pro Logic
produces four channels from two-channel
sound. Compared with the former Dolby
Surround system, Dolby Surround Pro
Logic reproduces left-to-right panning
more naturally and localizes sounds more
precisely. To take full advantages of
Dolby Surround Pro Logic, you should
have one pair of surround speakers and a
center speaker. The surround speakers
output monaural sound.
DTS
Digital audio compression technology
that the DTS, Inc. developed. This
technology conforms to 5.1-channel
surround. The surround channel is stereo
and there is discrete subwoofer channel in
this format. DTS provides the same 5.1
discrete channels of high quality digital
audio. The good channel separation is
realized because the all channel data is
recorded discrete and processed in digital.
