 The Ultimate Format.
If you are looking for a home theater experience, DVD is the way to
go. DVD, also called Digital Video Disc or Digital Versatile Disc, is the latest
revolution in video technology. The DVD system delivers
a picture with more than twice the detail of a standard VHS video tape. DVD Players utilize the latest digital technology
to give you high quality video and audio. DVD is rapidly gaining in popularity and
thousands of movie titles are currently available in this format.
DVD's can also feature  Dolby Digital and 
DTS for multi-channel digital sound and improved, multiple sound tracks - from mono up
to 5 channel surround sound. A single disc can hold large amounts of digital
data with a choice of language, subtitles and even multiple camera angles.
Video Resolution
DVD's can store 500 lines of
resolution, which is about twice that of VHS. This results in a clear, sharp, vivid
picture.
Video Outputs
DVD players typically have 4 types
of video outputs:
- Composite - this is the typical NTSC or PAL video output.
- S-Video (Y/C) - uses separate signals for chrominance (color) and
luminance (brightness). This makes for a more precise, detailed picture than standard
composite video output. Many newer televisions have S-Video inputs.
- Component - signal is separated into three components. Only
the latest mid and high-end TVs currently accept Component Video input. This
state-of-the-art video format is a step up from S-video output and creates an excellent
picture with very high resolution, better color accuracy and less color bleeding.
- Progressive Scan Component
Video If you have an HDTV or an HDTV-ready
television set you may be able to receive Progressive Scan images from your DVD player.
You must have a TV with Progressive Scan Component Video inputs. DVD Players with
Progressive Scan Component Video Output deliver super sharp film-like images to your TV,
even when objects onscreen are in motion. Flicker lines are virtually eliminated because
all 480 lines of vertical resolution are drawn 60 times a second instead of every other
line being drawn each 1/60th of a second as with standard 480i, or 480 line interlacing
video.
Audio Out
DVD players can come with these
audio output features:
- 2-Channel - This is the typical left & right audio
output.
- Virtual Surround Sound - this technology uses the 2-Channel output, but
manipulates the sound to provide 6-channel style audio.
- Digital Theater Sound (DTS) - DTS is a "5.1-channel" format that has
a separate output for each speaker (two front, two back, one center, and one
subwoofer).
- Dolby Digital 5.1 - Like DTS uses 6 outputs for each speaker, but
uses a higher compression algorithm, which can reduce the quality when compared to DTS.
Regions
There are 6 regions for DVD players &
movies. Make sure to get a player that is for your area. Disks that are assigned to
one region cannot be played by a DVD player from another region, although there are some
"Code Free" players that will operate in all regions.

- Additional Disc Formats
- Many DVD players can handle multiple disc
formats, including audio compact disc (CD), video CD (VCD) and the larger Laserdisc (LD)
Format. Other disc formats which players can accommodate include CD-R, CD-RW,
DVD-R and DVD-Audio formats. High-Tech Productions can transfer your VHS, S/VHS, 8MM, HI8, Digital 8, Betamax,
BetaCam or Mini DV tapes to DVD Disc's. Click Here for more info.
- Multiple Disc Player's
- The majority of DVD players take a single
disc. There are also models which will accept more than one. These are referred to as
"Multiple Disc Players" or "DVD Changers". The disc capacity of DVD
changers ranges from 2 to 300 or more discs. DVD Changers with a capacity of a hundred or
more discs are great for people who have a large CD collection and want to use their DVD
player as their primary CD changer for music as well as for movies.
