What is Home Theater?
Think of what makes movies in a theater so compelling. Consider the giant
screen, teeming with brilliantly detailed, vivid color pictures. Think of the sound,
sometimes booming with explosions, sometimes delicately whispering and always
immersing you in a full 360-degree experience. At the movies, these elements can come
together with astonishing emotional force.
Home theater is the technology that brings this experience into your room. And
there's never been a better time to make your move. Compared to the systems of just a
few years ago, today's home theaters enjoy far greater realism, drama and impact. Today
you can benefit from recent breakthroughs in electronics such as progressive scan DVD
players, flat-panel televisions and Dolby Digital® surround sound. What's more,
packaged systems make assembling a home theater easier than you ever thought possible.
So if you've been on the outside of home theater, now is the time to jump in. And
if your home theater is a few years old, now is the time to upgrade.
The Sony Guide to Home Theater 4
Why Sony?
No company is better prepared to provide your home theater than Sony. We co-
invented many of the essentials of home theater, including Compact Disc and DVD. Our
award-winning FD Trinitron® WEGA® television is the gold standard in picture quality.
Our Plasma WEGA™ and Grand WEGA™ televisions have won rave reviews. And
Sony leads the industry in both A/V receivers and packaged home theater systems.
The Sony CineAlta camera has been used to capture major
Hollywood action adventure movies, comedies, dramas, indie
films and a full range of episodic television, commercials and
music videos.
But that's only half the story. Our knowledge of the technology extends well
beyond your living room. After all, Sony Pictures Entertainment is one of Hollywood's
leading movie companies. Sony's CineAlta™ cameras are at the cutting edge of digital
movie making. Sony microphones, mixing consoles and digital audio recorders are
acclaimed by studio professionals. The Sony Dynamic Digital Sound® (SDDS®) system
is a fixture in movie theaters from coast to coast. And you can find Sony products in the
broadcast, cable and satellite TV studios where programming is created, edited and
distributed.
The Sony Guide to Home Theater 5
A breakthrough in professional audio, the Sony OXF-R3 Oxford
digital mixing console.
In all the world, no other company has this intensity of home theater focus—or
this breadth of home theater expertise. Only Sony.
The Sony Guide to Home Theater 6
What You'll Need:
Sources, Sight & Sound
Home theater combines three essential elements into one powerful experience.
These elements are Sources, Sight and Sound.
SOURCES. A good DVD player is the
essential source for today's home theaters. In
one easy purchase, a DVD player offers studio-
quality pictures, CD-quality sound and access
to the over ten thousand movies available on
DVD!
SOUND. To reproduce the full
impact of surround sound, home
theaters use at least a 5.1-channel
speaker system connected to an
A/V receiver that incorporates a
Dolby Digital decoder.
SIGHT. Home theater requires a big screen, at least 27
inches diagonal. Thanks to the "high scanning," "High
Definition monitor" or "High Definition upgradeable"
televisions, bigger is also better.
The Sony Guide to Home Theater 7
Home Theater Sources
DVD Players
The essential home theater source component, a DVD player is also one of the
best entertainment values today. It delivers digital picture quality that until recently you
would only have seen in a TV broadcast studio. You'll hear digital-quality surround
sound. You'll enjoy over ten thousand titles including movies, concert videos, children's
programs and more. Of course, compared to videotape, DVDs are more compact, more
durable and offer much faster access to individual movie scenes. And DVDs never need
rewinding.
DVD MOVIES. Thousands of titles are
available for sale or rent, each one
carrying the promise of spectacular
pictures and superlative sound.
Features to look for:
Progressive scan. This feature effectively doubles the picture quality. To get the
benefit of progressive scan, you'll want to connect your DVD player to a "high
scanning," "High Definition monitor" or "High Definition upgradeable" television. If
you own or you're thinking of buying one of these televisions, then a progressive
scanning DVD player is a must.
3-2 reverse conversion
is a technology employed in th
e better progressive scan DVD
players. It retains the integrity of the movie's original film frames. You'll see a
clearer picture, especially on scenes with movement.
The Sony Guide to Home Theater 8
Component video outputs. These Y/PB/PR outputs are a must for progressive scan
DVD—and they're highly desirable for all other players. They do the best job of
preserving the picture quality.
Component video outputs (Y/PB/PR) are the best way to convey
the full quality of the signal from the DVD player to the television.
MegaStorage® DVD changer capability. This lets you load any mix of up to 300
CDs and DVDs for pushbutton access to all your music and movies. No more
rummaging through the shelves. No more fumbling with jewel boxes.
Super Audio CD playback. These new high resolution discs provide the best sound
quality available today. And multi-channel Super Audio CDs are the perfect
complement to multi-channel home theater speaker systems.
DVD-R/RW, CD MP3 playback. It's best to get a DVD player that can handle all
the different types of discs you'll want to play.
Digital audio outputs. To enjoy surround sound, you'll want to connect the optical
or coaxial digital audio output of the DVD player to your A/V receiver.
Digital audio outputs feed the digital bit stream to your A/V
receiver for decoding.
The Sony Guide to Home Theater 9
About Progressive Scan
In video, what appears to be a continuously moving image is actually a series of
discrete still pictures, called frames. Each frame lasts 1/30 second each contains 480
scanning lines that appear on the screen. Because of limitations in the early days of
television, these 480 lines were divided into two "fields," each of which lasts 1/60 second.
The first field displays the odd-numbered scanning lines. The second field comes
back and displays the even-numbered scanning lines. This is "interlace" scanning and it
displays only 240 scanning lines at any one time. This system of 480-line interlaced
display is abbreviated "480i."
Interlace scanning (left) divides the frame into two "fields." The
first field presents the odd-numbered scanning lines (1, 3, 5, etc.).
The second field presents the even-numbered lines.
Progressive scanning (right) creates the picture by illuminating
each line from top to bottom until all scanning lines in the frame
are completed. Progressive images have twice the vertical
resolution, so they're noticeably clearer and sharper. And
horizontal scanning lines are far less conspicuous.
In the early days of television, when 12-inch diagonal screens were commonly
used in living rooms, showing only 240 lines was not a practical concern. But in today's
environment of 61-inch diagonal projection systems, the illusion of a continuous picture
on the screen begins to fall apart. Depending on how close to the screen you sit,
individual scanning lines become visible and the compromise in vertical resolution
becomes an annoyance. That's why most of today's finest DVD players and big screen
televisions have the ability to present a progressive scanning image. Instead of getting
240 lines, you get 480 lines every 1/60 second. This 480-line progr
essive scanning is
abbreviated "480p," and it delivers twice the vertical resolution of conventional video!
Connect a DVD player with progressive scan output to a "high scanning," "High
Definition monitor" or "High Definition upgradeable" television and the results are
phenomenal. You'll see images that are noticeably smoother and more film-like. It's less
like television, more like movies in a theater!
The Sony Guide to Home Theater 10
Super Audio CD Playback
A music source, Super Audio CD belongs in any discussion of Home Theater
thanks to multi-channel sound capability. You haven't enjoyed the ultimate in home
audio reproduction until you've heard a multi-channel Super Audio CD reproduced over a
multi-channel speaker system. Thanks to Sony's Direct Stream Digital™ recording
technology, the sound is an obvious improvement over Compact Disc and other digital
audio systems. And thanks to multi-channel sound, it doesn't just appear as if the
musicians are playing in your living room. It sounds as if you're transported from your
living room into the original performance space.
Over 600 Super Audio CD titles range from landmark jazz and classical
recordings of the analog era to the latest in rock and pop.
The Super Audio CD catalog
includes labels as diverse as Universal, AudioQuest, Chesky Records, Columbia, Delos,
DMP, Epic, Legacy, Sony Classical, Telarc, EMI and Virgin Records, to name just a few.
Over 600 titles of stereo and multi-channel Super Audio CD
represent a passion for beautiful music, beautifully reproduced.
As you'd expect, you can find Super Audio CD playback in dedicated audio
players. But you can also find the capability in many DVD-Video players and selected
home theater packaged systems.
The Sony Guide to Home Theater 11
Digital Satellite Receivers
With over 200 channels of entertainment, the DIRECTV® service brings an
incredibly rich array of programming options into your home. Subscribe to the service
and you'll be able to choose from pay-per-view movies and events, college and
professional sports packages, plus a long list of cable favorites. And in many cities, you
can even enjoy your local TV channels, brought to you by satellite! The DIRECTV
service provides digital picture quality, plus CD-quality digital sound including Dolby
Digital surround sound on selected channels. And the DIRECTV service even delivers
selected channels in the glory of High Definition TV!
Features to look for:
Support for DIRECTV local-to-local and multi-satellite programming. The new
receivers get the full benefit of the expanded DIRECTV channel lineup.
Dolby Digital optical passthrough. To enjoy surround sound, you'll want to connect
the optical digital audio output of the DIRECTV receiver to your A/V receiver.
High Definition reception. If you own or you're thinking of buying a "high
scanning," "High Definition monitor" or "High Definition upgradeable" television,
you should give serious consideration to a High Definition DIRECTV receiver. With
the right subscription, you'll have access to unforgettable pictures on HBO and
Showtime, in addition to sports and other programming on HDNet.
Powerful on-screen guide. With over 200 channels to choose from, you'll want a
receiver that makes choosing entertainment easy.
One button record. Make sure your DIRECTV receiver works seamlessly with your
videocassette recorder or personal video recorder. The infrared "blaster" supplied
with many satellite receivers can automatically switch your recorder on, put it into the
record mode and turn it off when the recording is done!
The Sony Guide to Home Theater 12
About High Definition Television
High Definition TV will dazzle you with up to six times the picture detail of
conventional TV. HDTV means a widescreen 16:9 picture with cinematic sweep and
grandeur. It also means Dolby Digital sound, including surround sound for movies and
TV dramas. Best of all, High Definition television is not a promise for the future. It's
here today. The DIRECTV satellite service carries three HDTV feeds (HBO, Showtime
and HDNet) to a national audience. Some cable TV services are beginning to offer High
Definition feeds. And HDTV is becoming more and more available in over-the-air TV
broadcasting.
In May 2003, the National Association of Broadcasters (NAB) reported that 885
television stations in 189 cities are broadcasting digital signals that can be received in
97% of American homes. More than 78% of homes are in markets with five or more
digital television broadcasters. And many of these digital broadcasts are in High
Definition.
An April 2003 NAB listing of shows broadcast in High Definition includes 8
Simple Rules for Dating My Teenage Daughter, Alias, American Dreams, Crossing
Jordan, Becker, CSI: Crime Scene Investigation, CSI: Miami, The Drew Carey Show,
Everybody Loves Raymond, Frasier, Hack, JAG, The King of Queens, NYPD Blue, The
Practice, Reba, Robbery Homicide Division, Smallville, The Tonight Show with Jay
Leno and Without a Trace, plus 40 other network TV shows.
This doesn't even count HDTV sports and special events, which have included
NCAA football, the Rose Parade, the Super Bowl, the U.S. Masters Golf Tournament, the
U.S. Open Tennis Championships, and the 2002 Winter Olympics. In addition, ABC has
announced that it will transmit the NBA finals and the Stanley Cup, as well as the 2003-
2004 season of Monday Night Football in HDTV.
For many viewers, one stumbling block on the road to HDTV has been the
relative lack of local HDTV broadcasts over cable TV. But recent agreements between
representatives of the consumer electronics industry and the cable television industry
have done much to clear the way to widespread distribution of local HDTV broadcasts
over cable.
The U.S. recommendations for Digital Television (DTV) broadcasting actually
encompass 18 different television formats. High Definition TVs and HDTV set top
boxes (usually called "HDTV receivers") are designed to tune all 18 formats. Six of
these are designated as "High Definition," while the others are called "Standard
Definition." All but a few formats can deliver a visibly better picture than conventional
television. Broadcasters have been encouraged, but not
required to use their DTV
spectrum for High Definition.

encouraged, but not required broadcasters to use their DTV
spectrum for High Definition broadcasting.
High Definition TV (HDTV) Receivers
To receive over-the-air High Definition broadcasts, you can choose a television
with a built-in HD receiver. But most customers are currently buying "high scanning,"
"High Definition monitor" or "High Definition upgradeable" televisions, which can
connect to an outboard HDTV receiver, purchased separately.
HDTV receiver features to look for:
1080i, 720p and 480p outputs to serve the widest range of High Definition monitor
televisions.
480i outputs to serve conventional televisions.
DIRECTV reception. Many receivers that will tune free, over-the-air HDTV also
function for the subscription DIRECTV service. So you can get complete HDTV
reception from a single set-top box.
DVI-HDTV interface enables superb, uncompressed digital-to-digital connection
from the set-top box to the television. Your High Definition signal is carried with full
picture quality. The connection is also secured by HDCP technology to protect the
signal from piracy.
The Sony Guide to Home Theater 14
The DVI-HDTV interface carries High Definition in full digital quality.
Component video outputs enable high-quality analog connection to a television.
The separate components of the video signal can be Y/Pb/Pr or R/G/B.
The D-sub 15-pin interface supports component video R/G/B
signals.
Dolby Digital optical passthrough. To enjoy surround sound, you'll want to connect
the optical digital audio output of the HDTV receiver to your A/V receiver.
Personal Video Recorders
A new generation of devices can record up to 80 hours of television onto a built-
in hard disk drive. This does so much more than the conventional VCR. You can pause
live TV when you need to take a break, then resume watching exactly where you left off.
So you're always free to take a phone call or take a trip to the kitchen. You can "rewind"
live TV and repeat a line of dialog that you might have missed. And you can have the
recorder capture up to 80 hours of TV shows, ready for viewing whenever you choose!
You can even rate TV shows as good or bad, and the recorder will "learn" your
preferences. The recorder can then automatically analyze the schedule of upcoming
shows and suggest programs with the actors, genres and subject matter you've liked in the
past. It's like having your own, personal TV critic on hand, ready to make the most of
every minute you spend viewing!
Features to look for:
TiVo™ service. This subscription service brings you electronic program guides.
The recorder can also "learn" your preferences and record shows similar to the ones
you like—a great way to discover new favorites.
The Sony Guide to Home Theater 15
Simultaneous record and playback. Here's another trick that hard disk recorders
can do that VCRs can't. This feature lets you record a current show onto the unit's
hard drive, even while you're watching another show that you've previously recorded!
Season Pass automatically records every episode of your favorite show every time it
airs—even if the network changes the schedule.
Wish List records upcoming shows with your favorite actor, actress, director or
keyword.
Auto VCR Transfer saves programs onto VHS tapes.
Network Media Receiver
Today's personal computers are increasingly important repositories of audio and
video entertainment. The ability to download, store and play music is rapidly being
joined by the ability to digitally record television shows onto the PC hard drive. Sony's
own Giga Pocket™ personal video recorder brings exactly this TV recording function to
selected Sony VAIO® PCs. In many homes, entertainment from the PC can be
distributed throughout the home via Ethernet cable or 802.11a wireless network. What's
been missing is a device to convert this entertainment from the IP language of networking
to the audio/video outputs required for a home theater system.
About the size of a paperback book, the PCNA-MR10
RoomLink™ media receiver delivers home entertainment content
from a compatible PC to your home theater system!
Now Sony meets this need with the PCNA-MR10 RoomLink™ media receiver.
The receiver has an Ethernet port on one side, and audio/video outputs on the other. It
can deliver music, digital still pictures, video and live television from compatible VAIO
PCs with VAIO Media™ software installed. Using the RoomLink receiver remote
control, you can browse menus on your television screen, giving you access to the
entertainment on your PC!
The Sony Guide to Home Theater 16
If your network provides no Ethernet cable near the home theater system, the
receiver can be connected to a Sony PCWA-DE50 for 802.11a wireless LAN connection
to a compatible wireless LAN access point.
VHS Hi-Fi VCRs
Even in the age of DVDs and personal video recorders, the old VCR still has a
role to play. Some movies are not yet released on DVD and some rental stores still have
more VHS cassettes than DVDs. You may own a shelf full of VHS movies that you still
want to play. VHS tapes are also easy to record and exchange with friends and family.
And VHS Hi-Fi tapes often contain Dolby Stereo sound tracks, suitable for Dolby® Pro
Logic® processing at home. This produces surround sound that's satisfying and dynamic.
Features to look for:
VHS Hi-Fi. An absolute must for high fidelity stereo sound.
VCR Plus+ Gold™ system automatically "maps" your local channel line-up.
Programming the VCR becomes as easy as dialing a telephone number, thanks to the
PlusCode® numbers you'll find in many newspaper TV listings and TV Guide®
magazine.
Four Heads. Two heads for SP speed and two for EP optimize playback picture
quality. They also enable better freeze frame, frame advance and picture search
special effects.
Built-in DVD player. A combination VHS/DVD player can save space and prevent
remote control clutter.
The Sony Guide to Home Theater 18
Choosing a Screen Size
The guidelines for choosing a TV screen size are not set in stone. Much will
depend on the amount of space you have for a television, the size of your room and
particularly the viewing distance. But the "right" screen size also depends on your
preference. If most of what you watch is movies on DVD and if you want to be
immersed in the full cinematic experience, you may be better off with a larger screen than
the one recommended here.
With these qualifications in mind, we present screen size calculators for three
classes of television.

Choosing a Screen Type
As we've mentioned, the range of available television screens has never been
greater. If you're into the technology, it's an incredible feast. If you're a little uncertain,
the sheer selection can be daunting. Here's a quick guide to what's what, and how to
choose.
Cathode Ray Tube (CRT) direct view.
WHAT IT IS. The conventional television. You're looking at the front of a large
glass envelope, the inside of which is coated with phosphors. The picture is formed
by an electron beam, the "cathode ray" that makes the phosphors glow.
BENEFITS. Despite the new competition, the CRT continues to be the most popular
type of television. It's not hard to see why. The age of the flat CRT, ushered in by
Sony's own FD Trinitron® picture tube, means that today's best CRTs are more
accurate than ever. Not only do CRTs offer the lowest cost for each screen size, they
also offer longevity and the best picture quality. With CRTs, the blacks are blacker
and the contrast is greater. You also get the widest viewing angle, and the bright
picture stands up well to ambient room light. And CRTs are not saddled with altitude
limits, so you can watch them anywhere.
LIMITATIONS. CRT televisions are the heaviest. A 32-inch CRT television can
weigh over 200 pounds and is typically over 20 inches deep. Direct-view CRTs are
also limited in screen size. Few CRTs are larger than 36 inches diagonal. Sony's
largest is 40 inches diagonal. Speakers need to be magnetically shielded, so as not to
interfere with the CRT electron guns.
The Sony Guide to Home Theater 20
Liquid Crystal Display (LCD) direct view.
WHAT IT IS. Liquid-crystal display technology first appeared in the early 1970's.
LCD is used in front projectors, rear-projection TVs, and flat-panel displays. Like a
laptop computer screen, a flat panel direct view LCD cons
ists of a panel of viscous
liquid sandwiched in plastic. The liquid is driven by a network of transistors that
control individual pixels. When a transistor delivers an electrical charge, the crystals
'untwist' to an exact degree to filter light generated by a lamp behind the screen.
BENEFITS. LCDs are far thinner, lighter and sleeker than CRTs, making them
favorites of interior decorators. LCDs also need no convergence. They're immune
from "burn-in," so there's never any harm from videogames left on too long, DVDs in
pause or station logos on the corner of the screen. LCDs also need no magnetic
shielding from your loudspeakers. And there are no altitude limits. So they're ideal
from sea level to Denver!
LIMITATIONS. Currently LCD televisions cost more and they are somewhat
limited in viewing angle and contrast ratio. LCDs are generally limited to screen
sizes of 30 inches and less, although larger sizes are soon to appear in the marketplace.
The Sony Guide to Home Theater 22
CRT rear projection.
WHAT IT IS. The most popular choice for giant screens. These are single piece,
self-contained televisions. They typically use three small CRTs—one each for red,
green and blue. The resulting light is projected through a lens and mirror system
behind the screen.
BENEFITS. As in direct view, rear projection CRTs offer superior performance and
moderate cost. With the clever packaging of today's rear projection systems, CRT
rear projectors are not much larger than rear projection systems using LCDs. And
there are no altitude limits.
LIMITATIONS. Can't quite match the viewing angle of direct-view CRT. Requires
periodic convergence adjustment to ensure CRTs remain in alignment and provide a
clear, sharp picture. To make convergence easy, Sony's Flash Focus™ system
performs this alignment in seconds. CRT rear projection can be affected by image
retention and "burn in." Care needs to be taken when selecting aspect ratio and using
videogames to avoid the possibility of image retention due to uneven aging of the
CRTs. And your speakers need to be magnetically shielded, so as not to interfere
with the CRT electron guns.
The Sony Guide to Home Theater 23
LCD rear projection.
WHAT IT IS. These systems shine a high-intensity light through a single LCD
panel or three individual LCD panels for Red, Green and Blue. The resulting light is
projected through a series of lenses and reflected off a mirror behind the screen.
BENEFITS. Systems that use three LCD panels—one each for red, green and
blue—can achieve superlative picture quality. LCD rear projection can deliver
slightly better color than typical DLP™ models because the three LCD panels can be
individually adjusted. LCD rear projection features compact size and light weight.
Easy bulb replacement by the user brings the television back to like-new brightness
levels. The LCD panels are fixed in place and therefore need no convergence
adjustment. LCDs are immune from "burn-in," so there's never any harm from
videogames left on too long, DVDs in pause or station logos on the corner of the
screen. LCDs also need no magnetic shielding from your loudspeakers. And there
are no altitude limits.
LIMITATIONS. Black levels and contrast still cannot match today's best CRTs.
Can't quite match the viewing angle of direct-view CRT.
The Sony Guide to Home Theater 24
LCD front projection.
WHAT IT IS. These are small, portable projectors that project an image onto a
separate component screen or a white wall. They work by shining a high-intensity
light through a single miniature LCD panel or three individual panels for Red, Green
and Blue. The resulting light is projected through a lens
system onto the screen.
BENEFITS. If you want the biggest possible picture, LCD front projection is the
definite way to go. You can project images as large as 25 feet diagonal. If you want
the least impact on your home décor, that's another good reason to go this route. In
portable use, you can place the projector on a coffee table. For permanent installation,
the projector can be suspended from the ceiling. So it's out of the way during daily
life. There's more. LCDs need no convergence and are immune from "burn-in."
They need no magnetic shielding from your loudspeakers. There are no altitude
limits. And the brightness comes from a light bulb that is replaceable.
LIMITATIONS. Ambient light needs to be controlled to get the brightest picture,
especially when projecting at the biggest screen sizes.
The Sony Guide to Home Theater 25
Features to Look For
High scanning/HD monitor/HD upgradeable television. These televisions accept
the full 1080 interlaced scanning lines (1080i) from an external High Definition
receiver or High Definition DIRECTV receiver. They also accept the 480
progressive scanning lines (480p) from progressive output DVD players. In both
cases, the picture is vastly more detailed than conventional television, which uses 480
interlaced scanning lines (480i). The difference is dramatic, especially in the larger
screen sizes. In big 480i screens, the scanning lines are so large that they can become
visible, undermining the sense of reality. In high scanning tele
visions, the scanning
lines blend seamlessly together into a more realistic, more emotionally compelling
image.
Digital Reality Creation™ circuitry. High scanning televisions generally boost
conventional 480i sources to higher line rates, such as 960i or 480p. Even though the
picture resolution does not change, you get a more seamless, more satisfying image
on the big screen. A big step up from a line doubler, Sony's family of Digital Reality
Creation™ circuits does an even better job. By replacing analog picture patterns with
their High Definition digital equivalents, DRC doubles the number of scanning lines
and doubles the number of pixels on each line. You get pictures with four times the
original picture density—approaching the quality of High Definition!
Sony's Digital Reality Creation circuit not only doubles the
scanning lines of conventional 480i sources, it also increases the
picture density to nearly that of High Definition sources.
CineMotion™ 3-2 reverse conversion is a technology employed in Sony high
scanning televisions. It overcomes the problems that can sometimes occur when
movie film, which is shot at 24 frames per second, is displayed on progressive
scanning televisions, which operate at 60 frames per second. In order to display 60
frames, some televisions take scanning lines from two adjacent movie frames and
force-fit them into one television frame. This makes a hash out of any object that's
moving on the screen. Vertical edges that should be smooth take on a disturbing,
