The most perfect example of the DVD format’s capabilities are in
the DVD-Video discs that people buy or rent from the video
store. The incredible storage capacities of these discs allow
MPEG-2 encoded videos to surpass the quality of VHS tapes and
Video CDs. These videos are presented at a screen resolution of
640 x 480 pixels with the option of choosing between standard
television ratio of 4:3, or cinema/letterbox ratio of 16:9. The
extra storage space also allows the video to be encoded at a
quality that is crystal clear even if displayed on huge 40+ inch
plasma television. Needless to say the DVD has become the
cornerstone for today’s home theatre setup.
Apart
from the unrivalled video quality, the DVD also provides the
viewer a completely immersive audio experience with the use of a
surround sound system. The extra data space on a DVD allows for
audio to be encoded to 6 different channels of digital sound
(front, front left and right, rear left and right, plus bass
subwoofer) as compared to the standard 2 channel stereo system
used on audio CDs. Movie companies even provide the option of
choosing what surround sound format to get, from Dolby Digital,
DTS, and THX. This factor has made the DVD the cornerstone of
today’s home theatre system. In fact, some home theatres can
easily rival the best commercial cinemas in terms of immersing
the viewer in the movie from an audio standpoint.
A
welcome addition to the movies that come in DVD is the level of
interactivity that was only previously available on CD-ROMs
meant for computer use. With the use of a typical DVD player and
a remote control, the user is given some of the following
options: choosing what ‘chapter’ in the movie to begin in;
frame-by-frame pause without the ‘stutter’ common on VHS tapes;
the option to display and choose from as many as 32 different
languages for subtitles; the option to choose from as many as 8
different languages for dialogue and soundtracks for the same
video; and the ability to watch commentaries from the movie
makers, view unedited cuts, and sometimes even play a game.
