DVD is the term which describes the next generation CD-ROM standard.
DVD was developed from the start to be a unified format for movies, audio, and computer storage. DVD disks are the same size as audio CD and CD-ROM discs, which makes DVD players backward-compatible with existing CD and CD-ROM disks. DVD was also developed to support future write-once (DVD-R) and read/write (DVD-RAM) discs.
DVD is supported by a consortium of major entertainment, consumer electronics and computer makers including, Fleming Multimedia Computers (part of the Fleming Multimedia Group), Sigma Designs, Toshiba, Time-Warner, MGM, Columbia Tri-Star, Microsoft, Sony, Philips, Matsushita, IBM, JVC, Hitachi, Mitsubishi, Pioneer, Thomson, and many others.
A DVD-ROM drive installed in a personal computer offers massive high-speed storage capacity of 17 gigabytes, which is over 25 times the capacity of a traditional CD-ROM. The same drive, which looks like a conventional CD-ROM drive, can support standard CD-ROM and CD-audio disks as well.
DVD videos have been released by Time-Warner, MGM and other major studios, and offer much higher video and audio quality than standard VHS tapes, as well as multiple video formats, foreign language sound tracks, subtitles, and navigational menus, which combine to vastly improve the enjoyment of home video.
For all of these reasons, DVD is expected to rapidly
replace all CD-ROM, Audio CD, video game and video tape products.
Originally, DVD stood for Digital Video Disk. As the
standard evolved to include additional capabilities, its meaning was changed to
Digital Versatile Disc. This didn't translate well into every language, so now
DVD doesn't stand for anything -- it's just DVD.
Currently, there are two ways to upgrade to DVD: You
can purchase a set top player for your television set, or you can purchase a DVD-ROM
upgrade kit for your computer, which consists of a DVD-ROM drive and a DVD
playback card, such as the REALmagic Hollywood. A set top player connects to
your TV set like a VCR, usually with an S-Video cable. With a DVD-ROM upgrade
kit, you install the DVD-ROM drive in place of (or in addition to) your
computer's existing CD-ROM drive. You then install the DVD playback card in your
computer's PCI slot, and run the Setup software which comes with the kit. With
REALmagic Hollywood, you can optionally connect a cable to your television set,
so that you can view movies on television set.Also software and new hardware can
play DVD with DVD Rom drive on your computer but does not have the DVD out that
DVD dDecoders do to play on your TV.
DVD-Video: Discs which contain movies which can be played using set top DVD players.
A read-only disk which can be used like a CD-ROM disk to hold computer programs, such as multimedia encyclopedias, games, reference material and so forth. DVD-ROM disks have a capacity of 17 GB. This storage capacity is available with the drives on the market today. When used with the REALmagic Hollywood, a DVD-ROM drive can play DVD-Video movie titles, as well as interactive titles which use MPEG 1 or 2 full motion video.
Write-once DVD drives. The disks created by DVD-R
drives can be played in any DVD-ROM drive. The DVD-R specification is finalized;
disk capacities will be 3.6 GB per side, which is less than the 4.7 GB/side
capacity of DVD-ROM's. DVD-R drives will be very expensive when first introduced
-- perhaps in the $10,000 - $20,000 range, and are therefore initially intended
for DVD content producers. We now have DVD Recorders for under 500.00.
Rewritable DVD drives. While availability is still a
few years off, these high-speed rewritable drives will be in high demand for
their ability to record data, sound and digital video in the highly-portable DVD
disc format, offering 2.6 GB per side.
Yes. Both set top and computer-based DVD players will
play Audio CD's. Computer-based DVD players will play existing CD-ROM's as well.
Maybe not. The first DVD-ROM drives released are
incapable of playing CD-R (recordable) disks. These DVD drives can actually
erase data from CD-R discs, so you must be careful not to use those disks in DVD-ROM
drives. Newer DVD-ROM drives, coming out in the Summer of 1997, will have a
second laser pickup for correctly playing CD-R discs. DVD-ROM drives which are
incompatible with CD-R typically display a warning sticker on the drive tray,
which you can see when you press the eject button.
No. Although CD's and DVD's are the same size, a
CD-Audio or CD-ROM drive won't know what to do with a DVD-ROM disc.
Yes. In particular, DVD's backward-compatibility with CD-ROM's makes it an ideal replacement for CD-ROM drives, and most new computers sold in 1998 will contain DVD-ROM drives, and not CD-ROM drives.
Because it is both a unified and backward-compatible
standard, offering vastly better performance in both the home video and computer
storage arenas, DVD is truly a "no-brainer" upgrade for computer
users. As drive prices fall and replace CD-ROM drives in new computer systems,
DVD will become a de facto computer standard.
No. The DVD-Video and DVD-ROM standards are completed.
Like CD-Audio and CD-ROM of today, the formats are as frozen today as they were
many years ago. True, DVD prices will drop, and drive speeds will increase, but
a DVD system purchased today will remain state of the art for several years,
until DVD-RAM drives appear on the market in the year 2000. While many consumers
will naturally wait for price drops, as with other computing technologies, many
will find that the value in having and using the product today is worth the
extra $100 or $200 savings that 8 to 12 months of waiting will deliver.
Most DVD's currently are a ROM (Read-Only) format. Reasonably priced
rewritable drives, called DVD-Recordable (write-once) and DVD-RAM (read/write),
Are now widely available.
Drive manufacturers have promised DVD-Recordables
(write-once) for the fall of 1997. While DVD-Video and DVD-ROM systems are
available for less than $500 today, the first DVD-R drives will start at over
$500.00. DVD-RAM (read/write) units became available until 1999 or 2000, A much
cheap DVD-RW has come out and will replace DVD RAM before too long.
When will movies become available? Right now. In March of 1997, DVD-Video was rolled out in 7 cities in the US, and distribution is expected to increase dramatically throughout 1997.
DVD Movies are now widely available at your local Video
When can I get them? Right now. Fifteen studios have
released movies already.
Right now. Silent Steel and several other titles have been released. Over 100 companies are preparing titles for Fall '97 release. Many games and interactive titles are now on the market.
What do set top DVD players do that REALmagic Hollywood
cannot? Nothing. Hollywood supports all of the features of set top DVD players,
including multiple sound tracks, closed captioning, navigational menus, and so
forth. To give set top players their credit, they're a little easier to set up,
and most include remote controls. Hollywood does not, although a Sigma Designs
OEM customer could sell Hollywood with a remote control. Finally, some high-end
DVD set top boxes include 5-channel audio output connectors for Dolby AC-3
receivers. REALmagic Hollywood doesn't include this connector, although it does
support the more commonly used Dolby Pro Logic
Lots. For one thing, with REALmagic Hollywood you can view movies on either a television set or a computer monitor -- or both!
Also, since the DVD-ROM drive is connected to your computer, it offers high-speed CD-ROM and DVD-ROM access, for standard software as well as upcoming DVD-ROM titles. These DVD-ROM titles can include full-motion, interactive video, offering unprecedented realism and interactivity.
Thirdly, REALmagic Hollywood plays MPEG-1 and MPEG-2
video from any source, with incredible clarity and smoothness.
There are several activities which Windows 95 and the
Pentium processor do to help REALmagic Hollywood work. A set top player doesn't
get a "host" -- it needs to provide its own processor, case, power
supply and so forth.
Dolby AC-3 Audio is a 5:1 channel surround sound playback system that provides incredibly realistic and exciting home theater performance. The 5:1 channels use 5 small "satellite" speakers and 1 sub-woofer speaker to provide complete, room-filling surround sound playback.
Currently, Dolby AC-3 is fairly expensive, requiring not only the 6 speakers but also an AC-3 compatible amplifier.
The biggest difference between Dolby AC-3 and Dolby Pro
Logic is that AC-3 gets its 5:1 channels from 6 separate outputs. So, instead of
connecting a stereo (2-channel) connector from the DVD player to the amplifier,
you would connect 6 channels to the amp.
Dolby Pro Logic is an established 5:1 channel surround sound playback system which includes all 6 channels of surround sound information in 2 stereo channels. A normal stereo amplifier can play a Pro Logic recording as stereo, but a Pro Logic amplifier can decode the "hidden" Pro Logic information to send all 6 channels to the speakers.
Pro Logic has been around for a few years, and is
available from virtually all audio manufacturers.
SP/DIF is a 5:1 channel audio connector which is used
to connect a DVD player to a Dolby AC-3 compatible receiver. Instead of sending
just stereo information, it sends 6 separate sound channels to the amplifier. An
SP/DIF connector is only useful if you have (or intend to purchase) a Dolby AC-3
equipped receiver and six surround-sound speakers.
No, REALmagic Hollywood is not currently available with
an SP/DIF connector. Instead, it converts the 5:1 Dolby AC-3 channels into 5:1
channel Dolby Pro Logic sound, which plays through your Windows sound card.
What's the difference between MPEG 2 video and DVD-Video?
The video portion of DVD-Video is MPEG-2. However, DVD-Video is a superset of
MPEG-2, because it also supports Dolby AC-3 audio, multiple audio tracks,
navigable menus, and several other features.
Yes, REALmagic Hollywood plays MPEG 1 and 2 files in
many versatile ways. For example, movies can be played using the DVD Station
software included with REALmagic Hollywood, using the MediaPlayer, or embedded
inside of interactive training, education and entertainment titles.

A bus-mastering IDE controller can access data more quickly than a conventional IDE controller. Fortunately, most Pentium/PCI systems have bus-mastering IDE controllers. The trick is installing the correct driver software for enabling bus-mastering. Windows 95B (OS/R2) includes bus-mastering drivers, but Windows 95A does not. Typically, you can find upgraded drivers on a manufacturer's website, including microsoft.com, intel.com, and compaq.com.
Microsoft requires a bus-mastering IDE controller and
driver for proper DVD-Video playback. If you do not install the bus-mastering
driver, the DVD-ROM drive won't always be able to send enough data. This will
cause dropped or jerky video frames, noise, and audio problems. Because
REALmagic Hollywood doesn't bog down the Pentium, these problems typically don't
happen when viewing a movie, unless you move the mouse, use another program
while the movie is playing, etc.
