By supplying film studios with
outstanding techniques for delivering soundtracks
to an attentive audience, DTS digital sound is now
featured on virtually 100% of major Hollywood releases.
Although the technology used for motion pictures
differs from that featured in consumer and professional
audio music and home theater systems, their DTS
heritage means end users can enjoy sound that closely
matches the original. Want to hear more about DTS

What
is HDMI?
HDMI (High-Definition Multimedia Interface) is the
first and only industry-supported, uncompressed, all-digital
audio/video interface. HDMI provides an interface
between any audio/video source, such as a set-top
box, DVD player, or A/V receiver and an audio and/or
video monitor, such as a digital television (DTV),
over a single cable.
HDMI supports standard, enhanced, or
high-definition video, plus multi-channel digital
audio on a single cable. It transmits all ATSC HDTV
standards and supports 8-channel digital audio, with
bandwidth to spare to accommodate future enhancements
and requirements. |

The Company's Founding |
|
| 
|
| Dolby
Laboratories was founded by Ray Dolby, who started
his career in high school, when he went to work
part-time for Ampex Corporation in Redwood City,
California. While still in college, he joined
the small team of Ampex engineers dedicated to
inventing the world's first practical video tape
recorder, which was introduced in 1956; his focus
was the electronics.

Upon graduation from Stanford University in 1957,
Dolby was awarded a Marshall Fellowship to Cambridge
University in England. After six years at Cambridge
leading to a Ph.D. in physics, Dolby worked in
India for two years as a United Nations Adviser
to the Central Scientific Instruments Organization.
He returned to England in 1965 to found his own
company, Dolby Laboratories, Inc. in London. Always
a US corporation, the company moved its headquarters
to San Francisco in 1976.

Q: What is
HDCD?
A:
High Definition Compatible Digital, or HDCD, is
a patented process for delivering on CD the full
richness and detail of the original microphone feed.
When listening to HDCD recordings, you hear more
dynamic range, a focused 3-D soundstage, and extremely
natural vocal and musical timbre. You get the body,
depth, and emotion of the original performance—not
a flat digital imitation. HDCD-encoded CDs sound
better because they are encoded with 20 bits of
real musical information as compared with 16 bits
for all other CDs. HDCD overcomes the limitation
of the 16-bit CD format by using a sophisticated
system to encode the additional 4 bits onto the
CD while remaining completely compatible with the
CD format. |

Blu-ray, also known as Blu-ray
Disc (BD) is the name of a next-generation optical
disc format jointly developed by the Blu-ray Disc
Association (BDA), a group of the world\'s leading
consumer electronics, personal computer and media
manufacturers (including Apple, Dell, Hitachi, HP,
JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips,
Samsung, Sharp, Sony, TDK and Thomson). The format
was developed to enable recording, rewriting and
playback of high-definition video (HD), as well
as storing large amounts of data. A single-layer
Blu-ray Disc can hold 25GB, which can be used to
record over 2 hours of HDTV or more than 13 hours
of standard-definition TV. There are also dual-layer
versions of the discs that can hold 50GB. |

Holography breaks through the
density limits of conventional storage by going
beyond recording only on the surface, to recording
through the full depth of the medium. Unlike other
technologies that record one data bit at a time,
holography allows a million bits of data to be written
and read in parallel with a single flash of light.
This enables transfer rates significantly higher
than current optical storage devices.
Combining high storage densities, fast transfer
rates, with durable, reliable, low cost media, make
holography poised to become a compelling choice
for next-generation storage and content distribution
needs.
In addition, the flexibility of the technology allows
for the development of a wide variety of holographic
storage products that range from handheld devices
for consumers to storage products for the enterprise.
Imagine 2GB of data on a postage stamp, 20 GB on
a credit card, or 200 GB on a disk.

What is DLP® technology?
| Digital Light Processing™ is
the world's only all-digital display chip and
a key ingredient in the best digital projectors
available today. DLP® technology uses an optical
semiconductor to recreate source material with
fidelity analog systems cannot match. Our Flash
demo will show you how it works.
