Welcome to

Ayre

Please send in your warrantyregistration card so we can

stay in contact with you.

Your Ayre DX-7 offers a significant advance in thevideo and audio performance of film reproductionequipment. The excitement and dimensionality ofyour favorite films are apparent from the firstviewing. The combination of superb resolution anda natural, relaxed quality will draw you back to yourhome theater, time and time again.

This level of performance has been implementedusing the highest level of workmanship andmaterials. You can be assured that the Ayre DX-7will provide you a lifetime of enjoyment.

Quick Start

The Ayre DX-7 is extremely flexible and versatile.However, many of the features are primarily ofinterest to the advanced user.

The information required to get started iscontained in the first three chapters of thismanual.

The remaining chapters cover additionalinformation that may be read at your leisure.

Connections and

Installation

The Ayre DX-7 is a DVD transport with digitalaudio outputs, requiring connection to an audioprocessor. It is easy to hook up and use. Thefollowing guidelines will ensure that the installationgoes smoothly.

Location

The infrared beam of theremote control will also travel

through glass.

A good location for your DVD player is at an easilyaccessible height in an open-backed cabinet or on ashelf. The receiver for the infrared remote control ismounted behind the display lens on the front panel.A direct line of sight from the listening positionwill ensure the maximum range.

Video Outputs

For additional information onconnecting multiple displays,

please refer to the section“Advanced Features”.

The progressive video option in your Ayre DX-7supports every type of video display device, as wellas all video standards around the world. All of thevideo outputs are active simultaneously. The DVIoutput is primarily intended for use with fixed pixel(i.e., digital) display devices or external video

processors. Analog display devices utilizing CRTsnormally achieve their highest performance whenusing an analog video output from the DX-7. Thevarious analog output options are listed below inorder of performance, from highest to lowest.Choose the highest performing connection that iscompatible with your video display.

DVI

There are two toggle switcheson the rear panel that

configure the DVI signal.Please refer to the section

“Setup and Configuration”.

DVI (Digital Visual Interface) provides a puredigital signal path from the DVD disc itself todigital (fixed pixel) display devices. This categoryincludes such technologies as plasma, DLP, D-ILA,LCD, and LCOS. The DVI connection is made via asingle multi-conductor cable equipped with arectangular multi-pin connector. Cable length isnormally limited to around 10’ (3 meters) unless anexpensive optical DVI cable is used.

The DVI signal from the Ayre DX-7 isunencrypted and therefore compatible with bothHDCP and non-HDCP capable displays.

Please note that some display devices using analogtechnology (i.e., CRTs) may have a DVI input. In

this situation it is usually preferable to use an analogcomponent connection rather than the DVIconnection. This is because the digital-to-analogconversion in the Ayre DX-7 will perform at ahigher level than the corresponding conversion inthe display device.

If in doubt about whichconnection to use, simply make

a visual comparison todetermine which offers better

performance.

However, a few of these CRT-based displays convertall incoming signals to digital for certain types ofvideo signal processing such as scaling. In this case,using the DVI conversion will be preferred as iteliminates two extra conversion steps. Consult theowner’s manual for your display for additionalinformation.

Component

The component interface is the highest performanceanalog interface. The component outputs can beconfigured in several ways:

• Interlaced or progressive

• YPbPr or RGB

• Embedded sync or external sync (RGB only)

There are three toggle switcheson the rear panel that

configure the componentsignal. Please refer to the

section “Setup andConfiguration”.

When configured as progressive RGB, the sync(timing) signals can either be added to the Greenconnection (Sync on Green, or SoG) for a total ofthree wires, or transmitted as separate horizontaland vertical sync signals (H+V Sync) for a total offive wires.

5

Please consult the owner’s manual for your displaydevice to determine which connections aresupported.

S-Video

There are two toggle switcheson the rear panel that

configure both the S-video andcomposite signals. Please refer

to the section “Setup andConfiguration”.

The S-video analog interface provides a good level ofperformance. The brightness signal is kept separatedfrom the color signal, but the color detail(bandwidth) is reduced from the componentconnection. S-video is commonly used forwhole-house distribution systems.

Composite

While the analog composite video signal from theAyre DX-7 offers higher performance than any otherDVD player, there are inherent performancerestrictions imposed by this connection. Thebrightness (black-and-white) and color signals aremixed together, and cannot be fully separated. Thisconnection is not recommended for critical viewing,especially when using a large video display.

Digital Audio Link

When the SyncroLinkinterface is connected, both

AES/EBU balanced digitalaudio outputs are

automatically turned off.

The Ayre DX-7 also includes a high performanceSyncroLink digital audio link. This link transmitsdigital audio data to an audio processor and also hasa separate master clock signal that is sent from thereceiver back to the DVD transport, completelyeliminating jitter. This interface is only compatiblewith SyncroLink-capable audio processors.

6

The SyncroLink interface automatically detectswhen a compatible SyncroLink device has beenconnected.

Digital Audio Outputs

An adapter is available fromAyre should you need to

connect one of the AES/EBUdigital outputs with an XLRconnector to an S/PDIF input

that uses an RCA connector.

The Ayre DX-7 features two digital audio outputs.Both are AES/ EBU balanced outputs to ensure thehighest possible level of sonic performance. One ofthese outputs will transmit both compressed formats(e.g., Dolby Digital and DTS) as well asuncompressed PCM formats (e.g., Compact Disc).This output should be connected to yoursurround-sound processor.

The other AES/EBU balanced output transmitsPCM only and is intended for use with atwo-channel digital-to-analog (D/A) converter. BothAES/EBU outputs may be used simultaneously.

AC Power

Connect the Ayre DX-7 to an unswitched powersource. The best performance is normally achievedwhen the DX-7 is plugged directly into the walloutlet, without using any power strips or power lineconditioners.

Break-In

Playing the unit for 100 to500 hours will ensure full

break-in.

Due to the manufacturing processes used for thewires and capacitors, a break-in period is necessaryfor the DVD player to reach its full performancepotential.

7

Setup and

Configuration

Once you have connected the Ayre DX-7 to yourhome theater system, you will need to configure itto ensure compatibility. There are two separateconfiguration steps – the video hardwareconfiguration using small toggle switches on therear of the unit, and the software configurationusing an on-screen Setup Navigator.

Perform the video hardware configuration first sothat the on-screen menus will display properly.

Video Hardware Configuration

Next to the DVI connector on the rear panel of theDVD player is a bank of eight small toggleswitches. These are used to configure the videooutput signal to properly match your display device.Two of these switches are used to configure the DVIoutput, three are used for the component output,and one is used for both the S-video and compositeoutputs. Two switches are reserved for future use.

You only need to configure the switches thatapply to the connection(s) you are using.

DVI Configuration

All display devices with a DVI input support theRGB format for the DVI connection.

“RGB” is the normal setting that should be usedfor DVI in most situations.

A few displays also support the YCbCr formatallowed by the HDMI specification, which(depending on the display) may allow for addedflexibility in color adjustments. Please refer to theowner’s manual for your display for additionalinformation.

When using the RGB format for DVI, there are twopossible signal levels. Out of 256 possible signallevels, the video standard (as used on the DVD itselfand in most DVI-capable displays) sets black at level16 and white at level 235. This allows headroom foroccasional video signal excursions outside this range(due to video processing or noise).

“16 - 235” is the normal setting that should beused for DVI in most situations.

However, some display devices were originallydesigned for presentations in conjunction with apersonal computer (PC) instead of video signals froma DVD player. The PC standard sets black at level 0and white at level 255. If your display device is notcompatible with the correct video levels for the DVI

input, set the level switch to the position labeled“0 - 255”.

Component Configuration

You must first determine what input signals aresupported by your display device. Please refer to theowner’s manual for your display for information.

If your display supports progressive inputs, thiswill provide significantly higher picture qualitythan an interlaced signal.

Select the desired signal by setting the toggle switchto either “Prog” or “Intrlc”.

RGB signals are commonlyonly used in the progressivemode. However, the DX-7will also output interlacedRGB signals if so desired.

The component outputs may also be configured foreither YPbPr signals or RGB signals. If your displayaccepts both types of signals, the RGB configurationnormally gives slightly better picture quality. Selectthe desired signal by setting the toggle switch toeither “YPbPr” or “RGB”.

When in RGB mode, there are two common ways ofsending the synchronization (”sync” or timing)signals — separate horizontal and vertical syncsignals, or a composite sync signal that is includedwith the Green signal. The former mode is calledRGB+HV and requires a five-wire connection. Thelatter mode is called SoG (Sync on Green) andrequires a three-wire connection. Select the desiredsignal by setting the toggle switch to either“HVSync” or “SoG”.

S-Video and Composite Configuration

The S-video and composite outputs only outputinterlaced signals. There are different standards forthese signals in different parts of the world. Theswitch marked “0%” and “7.5%” controls whetherthe black level is changed by adding setup to theNTSC signals. PAL signals are unaffected by thesetting of this switch.

Setup is normally only used in North America. Ifyou live in the USA, Canada, or Mexico, settingthis switch to “7.5%” will produce a signal thatmatches your other video source components.Residents of other countries should set this switchto “0%”.

Please refer to the chapter “Optimization andCustomization” for additional information onplaying DVDs from other countries.

Setup Navigator

The Ayre DX-7 has a wide variety of system settingsthat may be configured via the On-Screen SetupMenus (page 49). To simplify the initial setup ofyour player, the Setup Navigator allows you toconfigure the basic settings via a series of on-screenquestions.

Optimization and

Customization

The Ayre DX-7 offers many advanced features,especially when playing DVDs.

DVDs from Around the World

There are times when you may wish to play DVDsfrom other countries. In this situation there are twoitems that must be considered – whether the videostandards match between the disc and your videodisplay, and region coding issues.

World-Wide Video Standards

There are two commonly used video standardsaround the world, NTSC and PAL. NTSC is used inNorth America and Japan, while PAL is used inother areas, including Europe, Asia (except Japan),Australia, South America, and Africa.

There will be a label on the DVD package toindicate which video standard was used. The AyreDX-7 is compatible with both formats. Whenplaying an NTSC disc the player will output anNTSC signal, and when playing a PAL disc the

27

player will output a PAL signal.

However, many video displays will only accept onetype of signal and not the other. In order to viewDVDs using a different video standard, your displaymust be capable of accepting both types of signals.In general, most plasma displays and frontprojectors will accept both video standards, whilemost direct-view CRT televisions will only acceptone video standard. Please consult your owner’smanual for additional information.

Region Coding

In order to control distribution of DVDs, the DVDformat has incorporated region coding of both discsand players. There are six distinct regions that havebeen defined around the world. This coding systemnormally prevents you from playing discs fromanother region on your player, even if your videodisplay is compatible with the video standard on thedisc. However, the Ayre DX-7 has both automaticand manual region switching, so that DVDs fromany region may be easily played.

In nearly all cases, the automatic region switchingwill work perfectly. When the disc is loaded, theplayer queries the disc and temporarily adjusts itsown region setting to match the disc.

RCE Discs

There are some discs that attempt to prevent themfrom playing on region-free players, called RCE

28

(Region Coding Enhancement) discs. The AyreDX-7 can also play these, although you may need toset the region manually.

When the player queries these RCE discs, they tellthe player that they are from all regions. The playerthen cannot adjust itself automatically to the correctregion. The disc then queries the player to see if theplayer’s region matches the disc’s actual region.Playback is only allowed if the regions match.

To ensure proper playback of RCE discs, you mayneed to manually change the region of the player tomatch the RCE disc. This is accomplished via ahidden function in the On-Screen Setup Menus(page 63).

Since most RCE discs are Region 1, it is usuallyconvenient to leave the player set to Region 1also. Most RCE discs will then play automatically,and the player will automatically adjust to play theregion of non-RCE discs.

Multiple Video Displays

As all of the video outputs on the DX-7 are activesimultaneously, it is possible to connect more thanone video display at a time. This may be especiallyuseful in whole-house distribution systems.

Please note however that this practice may result ina slight decrease in your system’s performance. Thisis not due to any limitations of the DX-7; rather itis because modern video displays use switchingpower supplies that inject a level of noise into the

29

system’s ground connection that contaminates thesignals.

If you are using multiple video displays, you maywish to disconnect the auxiliary displays whencritically viewing the main display. Please note thatturning the auxiliary displays into Standby mode isnot helpful in this regard, as the switching powersupplies are still operating even when the videodisplay is in “Standby” mode. Instead you musteither disconnect the AC power completely from theauxiliary displays or disconnect the signal cablesjoining the auxiliary displays to your system.

Control Port

The Control Port on the rear panel of the DX-7allows the unit to communicate with a systemcontroller such as a Crestron or AMX. The ControlPort uses opto-isolators to ensure that there are nounwanted ground loops created when using a systemcontroller.

Pre-terminated cables, command files, anddetailed information regarding the Control Portare available upon request from the Ayre factory.

There are two separate functions performed by theControl Port; reception of commands andtransmission of the currently playing DVD’s aspectratio.

30

Control Port

Command Functions

The DX-7 may either be controlled by the remotecontrol via a receiver on the front panel or by asystem controller via the Control Port. A smalltoggle switch on the rear panel selects which modeis active.

For normal use, set this switch to “IR Receiver”.Set the switch to “Control Port” only when usinga custom programmed system controller.

Command files are available from the Ayre factoryin both Crestron and Pronto (CCF) format. Thesefiles include discrete on/off commands.

DVD Aspect Ratio Information

All DVDs use one of three aspect ratios; standard,widescreen, or letterbox. Each DVD has its aspectratio coded in the disc. The Control Port cantransmit this information to a system controller sothat the aspect of the video display can beautomatically adjusted to match the disc.

A few DVDs have incorrect aspect ratio codes.These discs will still require manual adjustment ofthe video display’s aspect ratio.

About

Aspect Ratios

The term aspect ratio simply refers to the ratio of anobjects’s width to its height. Nonetheless there issome room for confusion, as both the video displayitself and the picture stored on a disc have an aspectratio. Most viewers prefer to see the film in itsoriginal aspect ratio, which preserves the director’sintention for the composition of the film.

Aspect Ratios of Video Displays

Originally video displays were created with a 4:3aspect ratio, mimicking the original aspect ratioused in films. These types of displays are stillavailable today, and are often referred to as“standard” displays.

Most modern displays now use a 16:9 aspect ratioand are referred to as “widescreen” displays.Widescreen displays are preferred for displaying thewide aspect ratio movies that have been commonlymade for the last 40 years.

The aspect ratios of video displays are usually givenas a ratio of integers. However as noted below, the

33

aspect ratios of films are usually normalized to one.To make comparisons between video displays andfilms easier, the ratios for displays can also benormalized to one. Hence 16:9 becomes 1.78:1 and4:3 becomes 1.33:1.

Aspect Ratios of Films

Nearly all films made from the 1920s through theearly 1950s used an aspect ratio of 1.37:1. Tocompete against the threat of television, moviestudios began adding features such as color and awider (larger) picture.

Now nearly all films are made in a widescreenformat. The most commonly used aspect ratiostoday are 1.85:1 and 2.35:1. This wider pictureallows for more dramatic and creative visualcompositions.

Matching Film to Display

When the aspect ratio of the film closely matchesthe aspect ratio of the display, the film can easily beviewed as the director intended. This happens whenwatching a 1.37:1 film on a 1.33:1 standard videodisplay or when watching a 1.85:1 film on a 1.78:1widescreen video display, as there is only anegligible mismatch. But when there is a significantmismatch between the aspect ratios of the film andvideo display, some action must be taken to allowthe film to be viewed without distortion.

34

Widescreen Displays

Let’s start with a widescreen movie shot in 1.85:1and viewed on a 1.78:1 widescreen video display. Inthis case virtually the entire image can be seen withno adjustments required. The film is presented inthe same way as in a movie theater.

If we want to now watch a standard movie shot in1.37:1, we run into a problem. The narrower pictureautomatically fills up the screen, stretching anddistorting the image.

This is clearly unacceptable, so we use the “AspectRatio” control on the video display to shrink theimage horizontally, restoring the proper geometry.The display device also adds black (or sometimesgrey) vertical bars on each side of the picture. Thesecorrespond to the movable curtains used to blockpart of the screen in a movie theater.

A few widescreen displays erroneously lack an“Aspect Ratio” control when fed a progressivevideo signal. In this case, standard films areunavoidably stretched to fill the display. Oneworkaround for this problem is to feed bothprogressive and interlaced signals to the display.When watching a standard (1.37:1) film, selectthe interlaced input on the video display to allowadjustment of the aspect ratio.

35

Standard Displays

When watching a standard (1.37:1) film on astandard (1.33:1) display, we can see virtually thefull image without adjustments. Again, the film ispresented in the same way as it would be in a movietheater.

However if we watch a widescreen (1.85:1) film, wehave a new problem. The picture will be distorted asthe wide image is squeezed to fit the standarddisplay.

Again, this distorted image is unacceptable. A fewhigh-quality standard video displays will allow forthe vertical size of the picture to be decreased,restoring the proper image geometry. But sincenearly all standard displays lack any type of “AspectRatio” control, this capability is instead built intoall DVD players.

By selecting “4:3 (Letterbox)” for the “TV Screen”setting in the on-screen setup menus (see page 53),when a widescreen disc is played the player willautomatically squeeze the image vertically to restorethe correct geometry while adding black bars at thetop and bottom.

Additional Factors

So far everything has been relatively straightforward.However, there are a few more cases to consider thatintroduce some complexity to the situation.

36

Very Wide Films

Many films are made with aspect ratios even widerthan 1.85:1, such as 2.35:1. Even on a widescreen(1.78:1) video display these films would be distortedif they were simply allowed to fill the screen.Instead thin black bars are added to the top andbottom of the image on the disc itself when thetransfer from film to video is made.

On a widescreen display these will properly beshown as thin black bars. This is perfectly normaland there is no distortion of the image. On astandard display, additional black bars will be addedby the DVD player (or much less commonly by thedisplay itself). The end result will be thick blackbars at the top and bottom of the screen. Again thisis perfectly normal.

Pan and Scan Discs

Sometimes when a widescreen film is transferred toDVD, only the center portion is scanned. Thisprocess is called “pan and scan” and changes theaspect ratio to 1.33:1, allowing for viewing onstandard displays without the use of black bars.However this not only changes the film director’soriginal visual composition, but can even lead tocritical elements being left out of the pictureentirely.

These discs are often euphemistically called“fullscreen”. Most film enthusiasts prefer to watchthe film’s original aspect ratio and therefore avoidthese discs. As far as compatibility with either

37

widescreen or standard displays, pan and scan discswill work in the same way as standard 1.37:1 films.

Letterboxed Discs

Since all DVD players can convert a widescreen discto display properly on a standard video display,there is no technical reason to make a letterboxeddisc. However in the early days of DVD, moviestudios were selling to a much smaller audience ofDVD player owners. Instead of making a newtransfer to DVD in widescreen format, to savemoney they would use an existing transfer that hadbeen made for the laser disc format. Since laser dischad no provision for widescreen films, these transferswere done in letterboxed format, where the blackbars at the top and bottom of the image were addedto the disc itself during the transfer process.

These letterboxed discs will display properly on astandard display. However, on a widescreen displayyou will not only see black bars at the top andbottom of the image from the letterboxing processon the disc itself, but the display will add additionalblack bars at the sides of the image to maintain thecorrect picture geometry. The final result is a verysmall picture centered on your screen.

Most widescreen displays have a “zoom” mode thatwill expand the image in all four directions to fillthe screen. However, the picture resolution suffers asmany of the available pixels on the disc have beendiscarded. Fortunately as the market for DVDs havegrown these types of discs are now rarely seen.

If a setting applicable only to DVDs is changedwhile a Video CD or CD is loaded, a blue DVDicon appears in the upper right hand corner of thescreen to indicate that the setting does not applyto the currently loaded disc. The new setting willbe effective the next time a DVD is loaded.

Audio 1

The on-screen setup menu items listed under the tab“Audio 1” configure the Ayre DX-7 so that thedigital audio output will match the capabilities ofyour audio processor.

There are two digital audio outputs on the rearpanel of the DX-7. Some of these options only affectthe “Compressed + PCM” output, while othersettings affect both the “Compressed + PCM”output and the “PCM Only” output.

50

Dolby Digital

Nearly all DVDs have a Dolby Digital soundtrack(and optionally others as well). If your audioprocessor accepts Dolby Digital signals, set thisoption to “Dolby Digital”. The audio processor willdecode the Dolby Digital signal to recreate thesoundtrack.

If your audio processor does not accept DolbyDigital signals, set this option to“Dolby Digital > PCM”. The DX-7 will thendecode the Dolby Digital soundtrack and convertthe audio signal to two-channel PCM.

This setting only affects the “Compressed + PCM”output. The “PCM Only” output will alwaysconvert a Dolby Digital soundtrack totwo-channel PCM.

DTS

A few DVDs have a soundtrack using technologyfrom DTS in addition to the Dolby Digitalsoundtrack. When present, the DTS soundtrack willusually offer somewhat improved sound qualitycompared to the Dolby Digital soundtrack.

If your audio processor accepts a DTS signal, set theDTS option to “DTS”. Otherwise set the DTSoption to “Off”. The Ayre DX-7 will not convert aDTS soundtrack to PCM. If your audio processordoes not accept a DTS signal, instead select the“Dolby Digital” soundtrack.

This setting only affects the “Compressed + PCM”output. If a DTS soundtrack is selected, no signalwill be present at the “PCM Only” output.

96 kHz PCM

A few DVDs include a PCM soundtrack with asample rate of 96 kHz. This provides the highestpossible audio performance from DVD-Video discs.

If your audio processor will accept a 96 kHz PCMaudio signal, set this option to “96kHz”. If not, thenset this option to “96kHz > 48kHz”. In this case theoriginal soundtrack will be downsampled to thelower sample rate to allow compatibility.

This setting affects both the “Compressed +PCM” output and the “PCM Only” output.

MPEG Audio

Another technology used to store the audiosoundtrack on a DVD is MPEG audio. This wasproposed for use in Europe, but was quicklysupplanted by Dolby Digital by most film studios.Very few discs include an MPEG audio soundtrack.

If your audio processor accepts an MPEG audiosignal, select “MPEG”. Otherwise set the MPEGaudio option to “MPEG > PCM”.

TV Screen

It is extremely important to select the “TV Screen”setting that matches your display device. DVDs aremanufactured with two different aspect ratios for thepicture information itself (although black bars maybe added to the top and bottom of the pictureinformation to create many different aspect ratios forthe final displayed picture).

Video displays are also manufactured with twodifferent aspect ratios, 16:9 (widescreen) and 4:3(standard). Nearly all widescreen displays allow theaspect ratio to be adjusted so that all DVDs aredisplayed in their correct original aspect ratio.However most standard displays do not allow theaspect ratio to be adjusted, instead requiring theDVD player to modify the picture signal to createthe proper aspect ratio.

When the DVD player changes the aspect ratio ofa widescreen DVD to match a standard 4:3display, there is an unavoidable loss of verticalresolution.

If your video display is a widescreen model,configure this setting to “16:9 (Wide)”. If your

This setting affects the appearance of the picturewhen the DVD is paused. Normally this should beset to “Auto”. The DVD player then usesinformation on the disc to determine if it was madewith an interlaced source (i.e., video) or aprogressive source (i.e., film) However some discsare incorrectly flagged, causing the appearance of apaused picture to be unsatisfactory. Temporarilychanging this setting may improve the appearanceof a paused picture.

The operation indicators (“Play”, “Stop”, “Resume”,etc.) are normally displayed at the top of the screen.However, if you are watching a letterboxed DVD ona widescreen video display, it may be useful to usethe “Zoom” mode on the display to eliminate theblack bars at the top and bottom of the picture(page 38). However, the “Zoom” mode may alsoeliminate the operation indicators.

In this case, configure the “On Screen Display”setting for “Position - Wide”. This will lower theposition of the on-screen operation indicators so theyremain visible. Alternatively, you may choose toturn them off altogether by selecting the “Off”setting.

If the “Other” setting has been selected, you willhave the choice of entering the desired languagefrom either by scrolling through a list ofabbreviations (and also complete names for the morecommon languages), or directly entering a numericcode. The complete list of language codes may befound at the end of this chapter.

Subtitle Language

Many DVDs offer multiple language options for thesubtitles. You can specify the desired defaultlanguage setting for the subtitle. If that subtitlelanguage exists on a DVD, it will automatically beselected for play. In units shipped to most countries,the choices include “English”, “French”, “Spanish”,and “Other”. However, units shipped to Japan offerthe choice of “English”, “Japanese”, and “Other”.

Setup Navigator

The Setup Navigator simplifies the process ofconfiguring the on-screen menu settings of the AyreDX-7. This process in normally performed when theDVD player is installed in your system. However,any time you wish you may run the Setup Navigatoragain. Normally this is done only when newequipment has been installed in your system, or youmay choose to change the settings directly via theon-screen menus.

Parental Lock

The DVD format allows the player to blockobjectionable scenes from discs, using auser-specified access code. However, virtually nodiscs have been made that use this feature.Furthermore, it is not particularly difficult to defeatthe parental lock. For these reasons it is notrecommended to use the “Parental Lock” feature.

If you have used the “Parental Lock” feature andforgotten your password, the password can becleared by resetting the system (page 48). Pleasenote that the reset procedure clears all savedsettings, and not just the password.

A Technical

Glossary

480i A shorthand way of referring to an interlaced NTSCsignal, where “480” refers to the number of actualpicture lines and “i” refers to Interlaced.

480p A shorthand way of referring to a progressive NTSCsignal, where “480” refers to the number of actualpicture lines and “p” refers to Progressive.

576i A shorthand way of referring to an interlaced PALsignal, where “576” refers to the number of actualpicture lines and “i” refers to Interlaced.

576p A shorthand way of referring to a progressive PALsignal, where “576” refers to the number of actualpicture lines and “p” refers to Progressive.

AES/EBU The Audio Engineering Society and EuropeanBroadcast Union are standards setting organizationsin the US and Europe, respectively. The term“AES/EBU” is commonly used to refer to the systemof transmitting digital audio signals used inprofessional studios. This format is very similar tothe S/PDIF digital audio standard, although theperformance is higher due to the use of balanced

73

interconnect cables employing three-pin XLRconnectors.

Aspect Ratio The ratio of the video display’s width to its height.The two common aspect ratios used for videodisplays are 16:9 (1.78:1), also known as“widescreen”, and 4:3 (1.33:1), also known as“standard”.

CRT The Cathode Ray Tube is the original analogtechnology used in video displays. It is still usedtoday in both direct-view displays as well as frontand rear projection systems. Although themaximum light output levels are limited,CRT-based displays are unrivaled for theirsmoothness and ability to accurately reproduce finegradations in dark areas of the image.

Component A video signal using three separate videocomponents, for example RGB or YPbPr.Component signals may be either Interlaced orProgressive.

Composite An Interlaced video signal that combines brightness(black-and-white) information together with colorinformation. Performance is reduced compared toComponent video or S-Video, as the video signalscannot be perfectly separated again as required bythe display device.

Compressed Audio To allow storage of more video information on aDVD, the digital audio soundtrack is compressed totake up less room. The PCM digital audio data iscompressed by discarding data that is deemed to beof less importance. Various companies havedeveloped proprietary schemes for reducing the

74

quantity of audio data while attempting tominimize the impact on sound quality. See alsoDolby Digital, DTS, and MPEG Audio.

D-ILA Digital-Imaging Light Amplifier is a type of LCOSvideo display technology developed by JVC. This isone example of a Fixed Pixel display.

DLP Digital Light Processing is the name of TexasInstrument’s movable micro-mirror technology usedin video displays. This is one example of a FixedPixel display.

Dolby Digital A Compressed Audio format developed by Dolby Labs,this is found on virtually all DVDs.

DTS A Compressed Audio format developed by DigitalTheater Systems. A DTS soundtrack is found onsome DVDs, and in generally considered to soundbetter than the Dolby Digital soundtrack, in partdue to the higher data rates used (less compression).

DVI The Digital Visual Interface was developed as a wayto send digital video signals to a Fixed-Pixel (i.e.,digital) display without any additional conversionsto or from analog.

Fixed Pixel In a CRT video display the cathode ray, or beam,can be focused at any arbitrary point on the viewingsurface. Thus multiple Resolutions are easilysupported. In contrast, Fixed Pixel (i.e., digital)displays have the individual Pixels in predeterminedlocations. Incoming signals must be converted tothe native resolution of the display element itself.This conversion process, called Scaling, can introducevisible artifacts if not performed at a high

75

performance level. All fixed pixel displays haveinternal scalers incorporated internally.

HDMI The High Definition Multimedia Interface is anextension of the DVI interface that adds HDCP,digital audio, and inter-device communication link,all in a smaller connector. The DVI output of theAyre DX-7 can be connected to an HDMI displayby using an adapter connector. In this situation thevideo is passed through to the display device, butthere is no digital audio or communication linkpresent.

HDCP High-bandwidth Digital Content Protection is amethod of scrambling the DVI or HDMI videosignal in an attempt to avoid copying of copyrightedmaterial. Only “authorized” devices have the key todescramble the signal so that it is viewable. TheAyre DX-7 does not use HDCP, so it is compatiblewith all DVI and HDMI displays, whether or notthey use HDCP.

Interlaced An interlaced video system draws half of the picturelines on the video display at a time. Theodd-numbered lines are displayed in one pass andthe even numbered lines in the next. The interlacedformat was developed as a means of reducing thebandwidth required for television broadcasting, butcan result in visible artifacts in the picture comparedto Progressive video.

LCD A Liquid Crystal Display is the familiar display asfound on laptop computers. These are most oftentransmissive displays, where a white light sourcebehind the display element shines through colored

76

Pixels to create an image. This is one example of aFixed Pixel display.

LCOS Liquid Crystal On Silicon places the LCD displayelement directly on the silicon wafer that forms theelectronic control circuitry. A transmissive displayelement cannot be used as the silicon is nottransparent. Instead, a reflective display element isused. This is one example of a Fixed Pixel display.

MPEG Moving Picture Experts Group is an internationalstandards organization that developed the MPEG-2video compression algorithm used in the DVDformat.

MPEG Audio One type of Compressed Audio developed by Philips.This was originally proposed as the audio format tobe used on European DVDs, in a politicalcompromise designed to share royalty revenuesbetween Philips and Dolby. Philips was late tomarket with this format, and it has now largely beensupplanted by Dolby Digital.

MPEG Decoder The MPEG decoder is a highly complex integratedcircuit that decodes the video and audio informationstored on the DVD.

NTSC The National Television Standards Committee is thebody defining the television video signal formatused in the North America. Japan also uses avariation of this signal. This format has a total of525 lines, of which 480 are used for the actualpicture information.

PAL Phase Alternating Line is the video signal formatused in Europe, Asia (except Japan), Australia,

77

Africa, and South America. This format has a totalof 625 lines, of which 576 are used for the actualpicture information.

PCM Pulse Code Modulation is the fundamental methodused to store audio or video as digital codes. This isthe highest performing method of storing audio,and is the system used on CDs. See also CompressedAudio.

Pixel As a digital format, DVD reproduces video image asa grid of very fine colored dots. The smallestelement of this video image is called a pixel, whichis a shortened form of Picture Element.

Plasma A plasma video display uses ionized gases to excitecolored phosphors, similar to the way that afluorescent light bulb operates. This is one exampleof a Fixed Pixel display.

Progressive A progressive video system draws all of the picturelines on the video display in one pass. Commonlyused for computer displays, progressive video resultsin a more stable, flicker-free picture than doesInterlaced video.

RCE Region Coding Enhancement is a moresophisticated system of Region Coding developed toenforce the playback of DVDs only in their intendedregion. Playback of RCE discs may require changingthe DVD players region setting manually.

Region Coding In an attempt to control the distribution of DVDs,the DVD forum has designated eight differentregions throughout the world. Discs from any givenregion are normally only playable on DVD players

78

purchased from that same region.

Resolution Every video display device or video format has amaximum number of Pixels that can be displayed.This resolution is specified as the number ofhorizontal pixels by the number of vertical pixels.The resolution of a DVD is 720x480 for NTSC discsand 720x576 for PAL discs. Scaling must be used toconvert this resolution to the resolution of a FixedPixel display. The horizontal resolution of a CRT(i.e., analog) is somewhat ambiguous, as there are nodiscrete pixels used in this technology.

RGB RGB is short for Red-Green-Blue. The human eyecan visualize all colors from various combinations ofred, green, and blue light. All color video displaysuse red, green, and blue to create color. Any signalsinput to a color display device that are not in RGBformat must be converted to RGB before being sentto the display element itself. Except for computermonitors, most video display contain this circuitryinternally. When making an RGB connection to adisplay device, synchronization (timing) signals arealso required. This can be accomplished either viaRGB+HV or SoG.

RGB+HV Red-Green-Blue + Horizontal-Vertical is onemethod of transferring RGB video signals. In thisconnection method, the horizontal and vertical sync(timing) signals are separated from the video signalsthemselves. Thus a total of five wires are required.

Scaling Scaling is the process of converting a video signalfrom one Resolution to another. As with any type ofsignal processing, care must be taken to ensure thatthe signal is not degraded by the processing itself.

79

SoG Sync-on-Green refers to an RGB video connectionthat has the sync (timing) signals combined withthe green signal. Only three wires are required forthis connection, compared with five wires for anRGB+HV video connection.

S/PDIF The Sony/Philips Digital Interface Format iscommonly used to transmit digital audioinformation from a source (such as a DVD player) toa receiver (such as an audio processor). Theconnectors used for S/PDIF are common RCA(Cinch) connectors. Also see AES/EBU.

S-Video An Interlaced video signal that has two components;one for brightness (black-and-white) informationand another for color information. Performance ismuch better than Composite video, but due tobandwidth restrictions, has less color detail thandoes interlaced Component video.

UOP The DVD format allows the disc itself to sendcommands to the player. A User OperationProhibition is a disc-based command that tells theDVD player to ignore commands issued by the user.For example, some DVDs will display the FBIwarning at the beginning of the disc and issue aUOP that temporarily disables most usercommands.

YCbCr A digital Component signal, where Y is the brightness(black-and-white) signal, and Cb and Cr are thecolor signals. The picture on a DVD is stored inYCbCr format, as it requires less storage space for agiven visible resolution than does RGB.

80

YPbPr An analog Component signal, where Y is thebrightness (black-and-white) signal, and Pb and Prare the color signals.
