Digital video technology created by 
DivX, Inc. Videos encoded with DivX 
technology are among the highest quality 
with a relatively small file size.

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.

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.

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.

The Music mode is for use with any stereo 
music recordings, and provides a wide 
and deep sound space.

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.

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.
