since all the signals are processed digitally, less
signal degradation occurs.
Dolby Digital Plus
Developed as an extension to Dolby Digital, the
audio coding technology supports 7.1 multi-
channel surround sound.
Dolby Pro Logic II
Dolby Pro Logic II creates five full-bandwidth
output channels from 2 channel sources. This is
done using an advanced, high-purity matrix
surround decoder that extracts the spatial
properties of the original recording without
adding any new sounds or tonal colorations.
x
Movie mode
The Movie mode is for use with stereo television
shows and all programs encoded in Dolby
Surround. The result is enhanced sound field
directionality that approaches the quality of
discrete 5.1-channel sound.
x
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 decoding Dolby Surround,
Dolby Surround Pro Logic produces four
channels from 2 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 advantage of Dolby
Surround Pro Logic, you should have one pair of
surround speakers and a center speaker. The
surround speakers output monaural sound.
Dolby TrueHD
Dolby TrueHD is a lossless coding technology
that supports up to 8 channels of multi-channel
surround sound for the next generation optical
discs. The reproduced sound is true to the
original source bit-for-bit.
DTS
Digital audio compression technology
developed by DTS, Inc. This technology
conforms to 5.1-channel surround. This format
comprises of stereo rear channel 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 due to the all channel data

allowing you to enjoy high quality digital
picture and sound. The HDMI specification

Content Protection), a copy protection
technology that incorporates coding technology
for digital video signals.
Interlace format
