Dvd Terminology - Harman Kardon DVD 47 Owner's Manual

DVD TERMINOLOGY

the SACD disc is capable of storing more than seven
times the amount of data as on a standard CD.
Engineers realized that if they utilized a much higher
sampling frequency in a single-bit format, but eliminat-
ed the downsampling required to fit 74 minutes of
audio on a standard CD, they could preserve a much
higher quality of audio that more closely approximates
the original analog signal. In addition, the playback
equipment would no longer need to perform an
upsampling interpolation to play back the program.
Eliminating these two conversion steps minimizes dis-
tortion and artifacts, while enabling much higher reso-
lution. Most SACD discs are dual layer, including a
conventional CD layer for compatibility with older disc
players, as well as the SACD high-density layer. In
addition, SACD discs may contain two-channel or
multichannel versions of the program, or both.
Title: For a DVD, a title is defined as an entire movie
or program. There may be as many chapters within a
title as the producers decide to include. Most discs
include only one title, but some may have more than
one, to give you a "Double Feature" presentation or to
include other special features. Press the Title Button
T to see a listing of the titles on a disc. When a disc
has only one title, pressing the Title Button T may
show a list of the chapters.

WMA Files: WMA (Windows Media Audio) is an
audio compression format that was developed by the
Microsoft ® Corporation for use with its Windows Media
Player. WMA files can be even smaller in size than
MP3 files, while maintaining similar quality. The
DVD 47 is among those DVD players capable of play-
ing discs containing WMA files. Note that Windows
Media Player uses other file formats; however, the
DVD 47 is only capable of playing files that end in the
".wma" extension. See page 5 for more information
on WMA file support.
