Economy and Versatility: Extron’s Matrix 50 Series Switcher

(continued on page 2– See “Matrix 6400”)

Sixty-four signals in a single site—aninstaller’s nightmare; a cable seller’sdream-come-true. Computers, monitors,projectors, cameras, VCRs, videoreceivers, DVD, audio, and who knowswhat else, all in close proximity and indire need of some kind of centralizedcontrol. Does this sound familiar? Doesyour latest installation use a number ofdifferent signal types? Do you need todistribute a large amount of signals aswell as route them? If so, then the Matrix6400 series switchers are exactly whatyou need.

The Matrix 6400 series includeswideband/RGB, sync, audio, and videomodels. The Matrix 6400 Video model isa true 64 x 64 matrix with 80 MHz (-3dB)of video bandwidth, fully loaded. It iscapable of 132 presets (32 global, 100rooming) and will switch component, S-Video, and composite signals, making it

With hundreds of items available for theaudio/visual professional, Extron occa-sionally finds that a truly superiorproduct gets overlooked. The Matrix 50Series Switcher is just that—one of ourmost flexible and economic productsthat every system designer should befamiliar with.

One word sums up the Matrix 50:Versatility. Video configurations includemodels for Composite video, S-Video,and Component video (including RGsB)at 80 MHz, with four availableinput/output sizes: 12 x 8, 12 x 4, 8 x 8,or 8 x 4. Balanced or unbalanced two-channel audio switching is available inthe same sizes with any of these choicesor by itself without any video capabili-ties. Altogether, this gives the Matrix 50Series Switcher 28 possible configura-tions, providing solutions for numerousapplications.

possible by the use of removable video outputboards, each with eight outputs (see Figure 1).The Matrix 6400 Video model may be orderedwith as few as one of these boards, andremains expandable with additional field-installable boards available at any time. A fullcomplement of eight video output boardswould allow for a 64 x 64 configuration withcomposite signals, 32 x 32 with S-Video, or 21x 21 with component, as well as numerouscombinations of the three different signals, allwithin the same matrix switcher. As yoursystem grows, so will your Matrix 6400 Videomodel switcher.

But just how far will it grow? Each Matrix 6400Video model is capable of communicating withup to two additional BMEs (Basic ModuleEnclosures), which are then all controlled by thesame RS-232 port. This arrangement iscommonly used to break up the individual partsof an S-Video or component video signal,although combinations of S-Video, andcomponent are possible as well. For example,with S-Video, a pairing of two Matrix 6400Video models would have one switcher routingthe Y channel (luminance), and the otherhandling the C channel (chrominance). Withcomponent video signals, one switcher could be

used for the Y channel, another for the B-Y,and a third for the R-Y (see Figure 1). Theresult is that two Matrix 6400 Video modelswill switch 64 x 64 S-Video signals, or 32 x 32 with component video. With a thirdswitcher the system can coordinate the impres-sive total of 64 input and 64 output componentvideo signals. Add a Matrix 6400 Audio modelto the rack, and you can have as many as fourMatrix 6400s operating together as a true A/Vmatrix switching system. Like the videooutput boards, additional switchers may beinterconnected at any time, without anyfactory configuration.

RGB 406 & RGB 440:Architectural Powerby Mandi Speer, National Sales Manager

Extron’s InternalPromotion

Extron is pleased to announcethe promotion of Judy Cardozto Sales Support Manager. Inher new position, Judy will beresponsible for Extron’sinternal sales and technicalsupport.

During 1998, Judy, an eight-year Extron team member, hasperformed the role of northeastRegional Sales Manager. Shewas responsible for the salesand technical support activitieswhile also providing on-sitevisits, product training, andnew product introductions.Previously, Judy had held theposition of sales team leaderfor the northeast region for fiveyears. In addition, Judy hasprovided telephone support forExtron's northeast regionalcustomers.

Judy will continue to workfrom Extron’s Anaheim, CAheadquarters and may bereached at 714.491.1500.

JUDY CARDOZ

At Extron, we are known forproviding product solutions thatmeet the needs of our dealers andthe A/V industry. In 1998, weintroduced our 400 series architec-tural interfaces, and we are verypleased with the success of theseproducts.

As you probably know, our 400series architectural interfaces donot automatically ship with apower supply. These interfacestend to be mounted in inconspic-uous places, such as in walls,podiums, desks, etc., which do notlend themselves to power cords.An architectural interface isusually chosen because of a needfor an aesthetically pleasingappearance. The goal is to have theconvenience of an interfacewithout the bulk required bystandard models.

For this reason, in most cases,architectural interfaces arepowered from a central powersupply, enabling multiple productsto be powered simultaneously. Forinstance, when a system includes aproduct such as our System 5crswitcher, the System 5cr willsupply power for two interfaceslike our RGB 406 or RGB 440.Multiple units of the 400 series,including the RGB 406 & RGB440, can even be powered from asingle 24v doorbell transformer

found at your front door or yourlocal hardware store.

All of our 400 series architec-tural interfaces—the RGB 400,RGB 402, RGB 404, RGB 406,and RGB 440—can be poweredby 12-24 VDC or AC 250 mA.Other possible power sourcesinclude third-party controlsystems, such as AMX orCrestron, which may already beavailable in your installation.

By not automatically including apower supply with the RGB 406and RGB 440,we are able topass the savings on to you. Thatis good news. And, if you findyou still need the power supply,then we will be more than happyto make it available to you rightaway. The auto-switchable 100-240 VAC, 50/60 Hz to 12 VDC/1A external powersupply (PN: 70-055-01) can beeasily purchased as an accessoryitem and lists for $35.00. Thispower supply can power up tofour 400 series architecturalinterfaces. It is the best of bothworlds.

Comb Filters: NTSC Decoding Basicsby Steve Somers, V.P. Engineering

Notch Filter Decoders (Part 2)

Matrix 50 –continued from page 3

Those looking for an external controlmethod will be pleased to know that everyMatrix 50 includes an RS-232/RS-422serial communications port. This port maybe used in conjunction with Extron’sMicrosoft Windows™ based controlsoftware, which is also included withevery Matrix 50. This package is able toduplicate all the functionality of theQuickSwitch™ Front Panel Controller, butwith the convenience of the Windows™graphical user interface. Third partypackages may also make use of this portfor external control.

THE SWITCHER THAT GROWS ON YOUThe modular design that makes the Matrix50 Series so flexible also allows for field-upgrade-ability between all of the afore-mentioned options. As your requirementsexpand, so can your Matrix 50. This isaccomplished by installing one or more ofthe eight different Matrix 50 option kits.There are two kits for each I/O size, onefor audio capabilities, one for video.Through these add-on kits, a Matrix 50sold as an 8 x 8 Composite video andaudio switcher may be upgraded—at anytime—to handle 8 x 8 component videoand audio, simply by adding two 8 x 8Video Kits. In addition, if your originalnumber of inputs and outputs are no longersufficient, a new Video Kit may bepurchased to replace your existing one forconsiderably less than purchasing a newswitcher.

For more information on what we considerto be “the best unknown switcher on themarket,” please contact your local ExtronElectronics representative at: 714.491.1500(Extron U.S.); +31.33.453.4040 (ExtronEurope); or +65.226.0015 (Extron Asia).Also, see the Matrix 50 on the web at http://www.extron.com/product/matrix50.stm.

Here we are again. Figure 1page 8illustrates the basis of the NTSCdecoder system. Now, we have thedubious task of wading through thevarious methodologies for its disas-sembly. The most critical portion ofthe system is the first box in thatfigure… the Y/C Separator. Decoderquality totally depends on theapproach taken in this importantsignal processing function. Somehave devoted their entire career to theprocess of Y/C separation… youknow who you are. It is the functionwithin this one box in which thisentire series of articles is concerned.

There are fundamentally two methodsfor separating the luma (Y) informa-tion from the chroma (C) information.Both involve filters that are designedto discern one portion of the signalfrom the other. One is called a simple“notch/bandpass filter” and the secondis called a “comb filter.” The combfilter variants are numerous andcomprise the successive parts of thisseries. In this article, thenotch/bandpass approach is presented.

We learned about the creation ofNTSC in Part 1. Remember that thevisual image is made up of twocomponents… brightness and detailinformation (the higher bandwidthmonochrome portion) and the color

information (low bandwidth portion).The brightness and detail portion is theY channel, which represents the lumainformation, and comprises most of thesignal bandwidth. The color informa-tion, or chroma portion, is the Cchannel comprised of less bandwidth.In the composite signal, the chroma issuperimposed onto the luma channel.This is accomplished through carefulinterleaving of one component over theother by selection of the chromasubcarrier frequency… i.e., the 3.58MHz (the frequency is really3.579545… MHz).

NTSC DECODING…IT’S NOTch EASYFocus one eye on Figure 1. Separatingthe luma component from the chromacomponent is the main task in that firstbox. The designers of the NTSCsystem knew theoretically that it wouldbe possible to properly separate Y andC, but did not have a cost-effective wayto do it in the early years. In fact, themore sophisticated methods of separa-tion through “comb filters” did notarrive in the market until the late 70’s,more than 20 years after the system wasadopted.

So, early television receivers used theNotch/Bandpass Filter system for Y/Cseparation because the method has alow cost and is easily implemented

BNC-5 SuperFlex High Resolution Plenum-RatedCable with RipcordExtron’s BNC-5 SuperFlex HR Plenum Cable with Ripcordand sequential numbering offers a single solution to asituation with multiple needs: flexibility, plenum rating, easyin-field termination, and RGBHV distribution. Extron’slatest cable innovation is the built-in ripcord—it lowers thelikelihood of cable damage during installation and makesstripping the cable for termination quicker, easier and moreconvenient.

The BNC-5 SuperFlex HR Plenum Cable with Ripcord isideal for situations where the signal distribution includesseparate horizontal and vertical sync, such as when computersignals are being routed via interfaces, switchers, or otherpieces of A/V equipment to sensitive LCD projectiondevices.

The BNC-5 SuperFlex HR Plenum Cable with Ripcordconsists of five high-resolution, 75-ohm mini coax BNCcables that are color-coded and wrapped in a single jacket.This cable is the most flexible plenum-rated cable on themarket because the new SuperFlex jacket material provides

more flexibility for maneuvering in tight spots as well asease of use while rolling or unrolling. The plenum-ratedjacket is constructed with special fire protectant agents foruse where National Electric Code (CL2P) cable must beinstalled. Plenum cable can be run through open air spaces,eliminating the need for conduit, so using plenum cablesaves on installation costs.

The BNC-5 SuperFlex HR Plenum Cable with Ripcord isavailable in bulk spools of 500 and 1000 feet. For bulkspool lengths, this cable offers sequential numbering printedat one-foot intervals on the cable jacket, allowing for easymeasurement of cable length. You can find out how muchcable is left on the spool by figuring out the differencebetween the number at the end of the spool and the numberat the beginning of the spool, located on the cable at thespool’s axis.

For Extron’s BNC-5 SuperFlex High Resolution Plenum-Rated Cable with Ripcord, the 500' spool (PN: 22-103-02)lists for $1875.00 (US Dollars), and the 1000' spool (PN: 22-103-03) lists for $3750.00 (US Dollars).

with reasonable results. In many situa-tions, that approach is used today. Infact, most all of the digital decoders onthe market automatically switch back-and-forth between notch/bandpass andcombing as required. Watching a VHStape? You’ll most likely be operating inthe notch/bandpass mode even if youhave a comb filter in your display. Whyis it called a notch/bandpass filter?

Figure 2 illustrates the basic topology ofthis filter. The composite NTSC is inputto a system having two analog signalpathways. One pathway substantiallypasses frequencies from the region of the3.58 MHz subcarrier and lower. Here, aseries-resonant type passive filter(capacitor and inductor) is employedwhose resonant frequency is centeredabout 3.58 MHz. The operation of thefilter is such that as energy approaches itsresonant point, energy is dissipated in thefilter; otherwise it is allowed to pass on.Therefore, little energy within the colorsubcarrier region passes by the filter. The

result is a severe “notch” created in the Ychannel bandpass centered about 3.58MHz. This action substantially removesthe chroma information from theincoming signal and we realize the lumaor Y channel. But, we sacrifice highfrequency information, or horizontalpicture detail, above the color subcarrierfrequency region.

Conversely, the second pathway passesfrequencies just within the region of the3.58 MHz subcarrier. Here, a parallel-resonant filter (capacitor and inductor) isemployed whose resonant frequency is…can you guess? Yes, 3.58 MHz. Aparallel resonant filter acts in an oppositemanner in that it severely attenuatessignals that are not near its resonantpoint. Signals near its resonant point arepassed through as shown in Figure 2.The result is that the majority of thechroma information makes it through thefilter and we realize the C channel.

Now, mentally overlay the images of each

filter characteristic shown in Figure 2 andyou’ll see that significant overlap occurs.Regions exist where some luma energyfinds its way through the bandpass filterand some chroma energy finds its waythrough the notch filter. Hence, thenotch/bandpass approach is far fromideal. Analog methods do not allow forextremely precise control of filter charac-teristics, or in other words, the sides ofthese filters cannot be made very steep,so as to block unwanted information.These filter crossover regions are respon-sible for most decoding artifacts seen incolor decoders using this methodology.

SIDE EFFECTS… THEY MAKE MY CHROMA CRAWLVisual image side effects are the result ofluma and chroma components alternatelymaking their way through the wrongdecoding channel. You have seen theresults. When chroma information ispresent in the luma channel, it creates“dot crawl” or “chroma crawl” on thevertical edges of color details. Probably

the most noticeable examples are on thevertical edges of red lettering or othersimilar color objects. This artifact isreferred to as cross-luminance.

During moments when high frequencyinformation, or horizontal detail, ispresent, some of this energy will find itsway through the chroma channel. Itpresents itself as a “rainbow effect” inregions of the image having the highdetail. Remember seeing this effect onpeople wearing finely textured suits orclothes with narrow stripes? Thisphenomenon is called cross-color. It canonly occur within frequencies that “fit”within the bandpass of the chroma signalpath… or, about 3.0 to 4.0 MHz.

These two common effects primarilycharacterize an analog notch/bandpassdecoder scheme in a color display. And,

of course, the other most noticeable effectis the loss of high frequency details in theimage.

HEY, WE ONLY OPENED ONE BOXWell, we’ve only ventured through onebox in the decoder diagram (Figure 1).Unfortunately, there isn’t space to coverthe whole process here [amen. – ed.].Each of the remaining boxes deserves itsown article (let the editor or me know ifyou are interested). However, let’s justwrap it up in general.

That first box in the chain is the mostcritical. After Y and C are obtained, theY information must be delayed to accountfor the longer processing time required tosynchronously detect the phase and leveldifferences in the color subcarrier in orderto derive R-Y and B-Y, the color differ-ence signals. The color burst sample that

is sent on the backporch of the videosignal is used to key the local 3.58MHz oscillator so as to synchronize or“genlock” it to the incoming signal.When this local reference oscillatorfrequency is compared to the incomingC-channel information within the ColorDifference Decoder, the result is the R-Y and B-Y signals.

Once the color difference signals arederived, they are input along with the Ychannel to the Matrix Decoder.Remember that we can derive G-Yalgebraically if we have two of thethree components. The Matrix Decoderderives the G-Y signal from the twodifference signals. In addition, it alge-braically adds each of the differencesignals to the Y channel. The result isthe red, green, and blue video signalsused to drive the display device.

3200/6400 MATRIXVIRTUALIZATIONby Roger McCarten,Product Manager

Last year, Extron introduced its new 32 x 32 and 64 x 64 matrix switchers,the Matrix 3200/6400 Series. These newswitchers have been designed for easeof use. From the start, Extron’sengineers sought to design a matrixsystem that would be versatile and easyto upgrade—by the user. With theMatrix 3200/6400 switchers there is noneed to send any part of the matrix backto the manufacturer for upgrade orreconfiguration. These operations can bedone easily by the user in the field.

VIRTUALIZATION:THE KEY TO VERSATILITYOne of the features that make the3200/6400 matrixes so versatile isvirtualization. Virtualization allows theuser to electronically create switchingplanes of varying size and number asneeded. (A switching plane can bethought of as an individual matrixswitcher—electronically created withina physical switcher.) Through virtual-ization, multiple switching planes canbe created, or mapped,within onephysical switcher.

Figures 1A & 1B demonstrate theconcept of switching planes and virtual-ization. Figure 1Ashows a physicalswitcher (Extron’s Basic ModuleEnclosure or “BME”). This is a low reso-

lution BME that has been electronicallymapped out, through virtualization, to bea 32 x 32 switching plane. Therefore, thisphysical switcher will behave as one 32 x 32 composite video switcher.

Through virtualization, this samephysical switcher (BME) can be elec-tronically re-mapped into three inde-pendent 8 x 8 matrix switchers. Thisway the same physical unit can bemapped to be an 8 x 8 composite videoswitcher and an 8 x 8 S-Video switcher.The bottom two 8 x 8 planes willswitch together to handle the Y and Cchannels.Figure 1Bshows this re-mapped switcher.

One of the advantages of virtualizationis demonstrated in Figures 2A & 2B.Suppose a user has one physicalswitcher, as shown in Figure 2A. Thisis a 64 x 64 BME. Currently it is beingused to switch R, G and B and hasbeen mapped out as a 21 x 21 RGBswitcher (3 switching planes, one eachfor R, G, and B). Suppose the require-ments change and there is a need toincrease the matrix size to 32 x 32?

With virtualization, this can be easilyaccomplished. Simply add a 32 x 32physical switcher (BME); then usevirtualization to re-map the two BMEsinto a 32 x 32 RGB virtual matrix. Theresulting switcher can be seen inFigure 2B. Here the physical units havebeen re-virtualized and three switchingplanes for R, G and B now exist on thetwo physical switchers.

IT’S EASYExtron’s matrix control program makesvirtualization easy. The 3200/6400Series switchers can be set up withExtron’s Windows-based matrix controlprogram. With this program, the usersimply indicates the size and type ofthe desired switcher, and the programwill map out the hardware to create thedesired virtual switcher. The programwill also provide printouts of theresulting configuration, i.e., indicatingwhich outputs have been assigned forwhich color and sync signal.

If a hardware upgrade is required, thisis also easy. Extron’s 3200/6400 Seriesmatrix switchers can be upgraded inmost cases by adding circuit cards to aBME or by adding a BME. Either ofthese operations can be done easily inthe field. Once the hardware upgradehas been done, Extron’s matrix controlprogram can then be used to create thedesired virtual switcher.

Extron’s products are not only designedto achieve the highest levels of qualityand performance, but to be as user- andinstaller-friendly as possible. As Extron’snewest computer-video interface, theRGB 190 is no exception. The RGB 190is a compact, universal computer-videointerface designed to be mounted trulyanywhere, as well as to use an HD15input; Extron’s first universal interface todo so.

The RGB 190’s one-inch tall enclosureand optional detachable mounting kitsgive it remarkable flexibility. The under-desk mounting kit gives it the ability tomount on or under any flat surface, suchas a desk, podium, table, cabinet, wall,etc. Where the RGB 190 differs from allother interfaces is that it will also mountthrough any of these surfaces. This isaccomplished through the use of thethrough-desk mounting kit, whichattaches to the sides of the interface andfits flush against the surface being pene-trated. Wherever you need your interfaceto be, the RGB 190 is ready to go.Once mounted, the RGB 190 is clean inappearance and is easy to configure. Allcontrols are placed on the front panel of

RGB 190Extron Re-invents the ”Anywhere“ Interface

the interface, and next to the HD15 inputand buffered local monitor output. AllBNC jacks are conveniently located,instead of on top of the interface rear.The result is that no jacks or cables willhang down from the device in a hori-zontal installation, and therefore theinterface is less likely to be snagged orhit someone’s knees.

The RGB 190 has 350 MHz (-3 dB) ofvideo bandwidth and provides a 15 to150 kHz frequency range. This makes itcompatible with a wide range ofcomputer signals including VGA,SVGA, XGA, XGA-2, Mac, Quadra,SUN, SGI and more. Its six BNCconnectors allow for buffered output of

RGsB (sync on green), RGBS, RGBHVwith simultaneous composite sync,making it suitable for any large displaydevice.

The RGB 190 also features adjustablehorizontal shift, video level boost, andDigital Display Sync Processing(DDSP™). When DDSP is activated,sync signals will be output unprocessedto ensure signal compatibility with LCD,DLP, plasma and other digital displaydevices. The RGB 190 also includesproper ID bit termination, allowingmachines that normally operate withoutlocal monitors to continue to function.

The RGB 190 (PN: 60-280-01) lists for$350 (US Dollars). Please note that boththe under-desk and through-deskmounting kits are optional add-ons anddo not ship with the basic product.

Audio Specs Spelled OutAudio specifications, exactly what do theymean? What is actually being measured?Most people in the A/V industry probablyhave a general idea of what common audiospecifications mean. However, it is importantto understand how each specification ismeasured and what the measurement specifi-cally tells the reader about the performanceof the equipment. In the following section anumber of the more common audio specifica-tions will be discussed.

Frequency Response:Frequency response is the measurement ofsignal amplitude over a specified frequencyrange. Typically, this is a concern withbuffering and routing equipment (audio DAs,audio switchers, etc), as opposed to audioprocessing equipment (such as audio equal-izers). Frequency response is usuallymeasured over the range of 20 Hz to 20 kHz,which is essentially the range of humanhearing. There should also be a dB valuelisted with this range. The dB value indicatesthe amplitude variation over the frequencyrange, or the flatness of the frequencyresponse. The less variation of amplitudeover this range, the better.

Frequency response is determined byapplying a series of specific frequencies to anamplifier and then measuring the output levelfor each frequency. A plot can then be madeof the amplifier's frequency response. Figure1 shows a graphical representation of afrequency response measurement.

As a real world example, the frequencyresponse spec for the audio section ofExtron's CrossPoint matrix switcher is: +/-.05 dB from 20 Hz to 20 kHz (.05 dB isconsidered quite low). This tells the readerthe audio amplitude won't vary by more than+/- .05 dB over the 20 Hz to 20 kHz range.

Occasionally a manufacturer may listfrequency response as simply “20 Hz to 20kHz,” with no dB value listed. This may tellthe user the range over which the amplifierwill work, but this doesn't tell the useranything about the flatness of the response.Further inquiry should be made in such cases.

Signal to Noise Ratio (S/N) This specification is a measurement of hownoisy the audio equipment being measured isin reference to the signal level. The actual

measurement is the ratio of the signal level tothe noise level, and is expressed in dB. Thesignal measurement is made by applying anaudio signal to the amplifier to be tested(usually in the 1 kHz range), after theamplifier has been set to either the maximumoutput level, or the normal output level. Thesignal output by the amplifier is thenmeasured.

The noise level is determined by measuringthe output of the equipment with no signalapplied. The noise level is measured across aspecified bandwidth, or through a weighingfilter. Once the signal level and the noiselevel have been measured, the ratio of thesignal level to the noise level is computed.This ratio is then expressed in dB. Typically,this can be considered the effective dynamicrange of most analog devices.

Note: To measure the noise level of digitalaudio equipment it is necessary to supply asignal to the unit and then use filters toseparate out the noise. The noise level ofdigital audio equipment cannot be deter-mined by simply measuring the outputwithout an input signal (as is done withanalog audio equipment). When no signal issupplied, the digital conversion circuits willlikely not work normally, and an actual noiselevel cannot be produced.

CrosstalkCrosstalk is a measure of signal leakage fromone channel to another. The crosstalkmeasurement should not be confused with themeasurement of stereo separation-– althoughthese two terms often get used interchange-ably. The measurement technique is the samefor both of these specifications, but thecrosstalk measurement deals with channelsthat carry independent signals (e.g. input 1and input 2). On the other hand, stereo sepa-ration refers to the signal leakage betweentwo channels (left and right) which carry astereo signal.

Crosstalk is specified in dB, the level ofthe signal leakage. Crosstalk should bespecified in relation to a particularfrequency. Since crosstalk results frominductive and capacitive coupling, thedegree of crosstalk will vary according tofrequency. Therefore, crosstalk specifica-tions should be compared at similarfrequencies.

Total Harmonic Distortion (THD)Total Harmonic Distortion is determinedby measuring the amplitude of a series ofharmonics. The actual calculation is madeby adding the sum of the squares of theindividual values, then taking the squareroot of this value. So what does this tellthe user? It's simply the measure of theamount of distortion generated by theamplifier. This specification requiresrather unusual equipment to measure,and Total Harmonic Distortion + Noise(THD + N) is usually listed instead ofTHD.

Total Harmonic Distortion plus Noise (THD+N) This measurement is more common thanstraight THD. In fact, in discussions,people often mean THD+N although theyrefer to the measurement as "THD".THD+N is just what it says, the THDvalue and the noise value combined.Figure 2shows the setup used to measureTHD+N.

To determine THD+N, a signal of specificfrequency is fed to the amplifier.Following the output of the amplifier, anotch filter is used to filter out the initialtest frequency, leaving only the harmonicsgenerated by the amplifier and the noise.A band pass filter is used to limit therange of frequencies/harmonics that willbe measured as noise. Finally, the noiselevel is measured as voltage. Thismeasurement is one of the most realisticin that it measures the harmonics andother noise while an actual signal is beingprocessed by the amplifier.

Unique Techniques:Disney Rolls Out DTVOn November 1, 1998—a landmark day inthe broadcasting and A/V industries—commercial broadcasting in digital and highdefinition television formats began in theUnited States. Among the networks takingpart was ABC, which transmitted Disney’s101 Dalmatiansin 20 U.S. cities. As part ofthis momentous event in television history,ABC held a special screening of the moviefor parent company Disney’s employees andtheir families at their California studios.Several Extron products, including the CVC100 component video signal converter, wereused in the event.

The screening was to be shown on threePanasonic DTV monitors and an NEC DLPprojector. A Tiernan satellite receiver wasused to pick up the signal, as Disney did nothave an off-air receiver available at thetime. To make it all work, Disney asked JoeKane of Joe Kane Productions to help out.Mr. Kane is one of the DTV industry’sleading experts, and has been a long-standing proponent of the 720p DTVformat, which ABC/Disney uses in theirbroadcasts.

“I found a need for video signal distributionas well as display device setup,” said Kane.To resolve these issues Mr. Kane elected torun a component level signal from thesatellite receiver and into an Extron ADA 6300 distribution amplifier. From there, threelines were run to the Panasonic monitors,while the DLP line ran to an Extron CVC100 component video converter. The CVC100 was brought in to convert thecomponent signal to RGB, which was theonly format the NEC DLP would accept.

Why were component signals used and notRGB, particularly when all the devices,including the receiver supported RGB?“Whenever possible, I distribute Y Pb Pr(component) to make setup much easier,”Kane replied. “In setting up any displaydevice it is critical that the black and whitebe correct before you can possibly get agood color picture.” Unfortunately, black andwhite test patterns are not readily available in

the DTV world. This can be remedied by using component video signals, disconnecting theblue and red leads, and conducting black and white setup on the remaining Y (luminance)channel. “From there, it is much easier to judge picture saturation in setting the peakcontrast and easier to set up an appropriate level for black, as well as touch up gray scale.It’s also much easier to check convergence with a black and white signal than one incolor,” Kane said. When using RGB-only devices such as the NEC DLP projector,Extron’s CVC 100 may then be used to convert the component signal to RGB.

Joe Kane Productions frequently uses the CVC 100 for this kind of operation whendemonstrating the 720p DTV format. Kane has made appearances at the HI-FI and NABconventions, just to name a few, and was also present at the ABC press conference wheretheir use of the 720p format was announced. It was this connection to ABC thatprompted them to request Kane’s presence at the 101 Dalmatiansscreening. “It’s beenexcellent to have [the CVC 100] in our 720p demonstrations,” proclaimed NicholasGrieco, of Joe Kane Productions.

One of the great features of Extron’s new System 5cr switcher is the product’sability to work in tandem with a projector’s remote control unit. Now you can“teach” your System 5cr to work with the remote by programming the unit manually.

But what if you don’t want to take the time to program your System 5cr to yourremote? Extron has taken the bulk of the work out of this endeavor by writingdrivers for most common projectors, and you can now download them directlyfrom Extron’s Web site. Be sure to check the site often, as new projector driverswill be posted regularly.

To get System 5cr drivers:• Visit Extron’s System 5cr drivers page on the World Wide Web at:

http://www.extron.com/product/software/drivers.asp• Click on the link that corresponds to your projector make and model. When

prompted, save the file to your hard disk. Make sure to save the file to the “drivers” subdirectory of the System 5cr program directory (for instance, c:\system5cr\download)

EXTRON’S CVC 100

Matrix 6400–continued from page 2 CEDIA Regional Education Program

An integral part of Extron’s corporatephilosophy is educating A/V industryprofessionals. As part of that educationalprocess, Extron has conducted seminars andworkshops at the CEDIA RegionalEducation Program, ICIA’s INFOCOMM,the ICIA Academy and ProfessionalDevelopment programs, Extron School, andExtron School on the Road.

Extron is pleased to announce that Extrontrainers will again present two courses aspart of the 1999 CEDIA RegionalEducation Program for members of the resi-dential installation market. CEDIA(Custom Electronics Design and InstallationAssociation) is an international associationof companies that specialize in planningand installing electronic systems for thehome. “Ongoing feedback tells us that ourcourses were extremely popular,” statesChris Gillespie, Extron Trainer, “becauseattendees enjoyed getting a behind-the-scenes look at how things work with theadvent of HDTV and computer integrationinto the home. Installers are implementingincreasingly complex home electronicsystems, such as home theaters.”

This year CEDIA Regional EducationProgram has been expanded to includeseven sites—five in the USA and two inCanada—providing people a wide choice of

dates and locations. Extron will offer twocourses: Understanding the Importance ofBandwidth and Different Video FormatsandSignal Integration in the ResidentialMarketplace.

Course 1: In Understanding the Importanceof Bandwidth and Different Video Formats,Extron trainers will provide an overview ofvideo bandwidth and its significance insystem design and installation. Specifically,Extron trainers will discuss the “foodchain” of video quality, from RGBHV tocomposite, and which is best to use forspecific installations.

Course 2:In Signal Integration in theResidential Marketplace, Extron trainerswill explain how to integrate computer-video, multiple video, audio sources, andother technologies into a residential system.Extron trainers also will discuss how to getthe most from the latest technologies forfuture installations, covering topics such asswitching & routing, computer-video inter-facing and signal distribution.

One might think that with this much power,configuring a system with as many as 384 inputand output BNC connections might be difficult.While whoever is stuck with the crimper mightnot agree, this simply isn’t the case. With thehelp of Extron’s System Virtualization/ControlSoftware, configuring for and controllingmultiple switchers and signal types is not onlypossible, but fairly simple as well. Just enter thenumber of inputs and outputs you need andwhat types of signals are to be used, and thesystem does the rest. The number of Matrix6400 Video Models will be detected automati-cally, and the software will assign inputs andoutputs for each signal. At this point, themultiple connections used with component andS-Video signals are “virtualized,” and showngraphically as single signals. Switching willnow automatically occur on all lines withoutadditional factory or dealer configuration, evenif the lines that make up the signal are ondifferent Matrix 6400s. All you have to do isdetermine what and how many signals are to beswitched, and your Matrix 6400 will make ithappen.

Virtualization of inputs and outputs also workswhen using the Matrix 6400 Audio model inconjunction with one or more Video models.This is commonly done to provide convenientswitching of the audio and video signals origi-nating from the same source. Conversely, withaudio breakaway, any audio signal may beswitched with any video signal, regardless ofsource. Altogether, virtualization of audio anddistributed video signals—whether controlledwith Extron’s System Virtualization/ControlSoftware, MKP-1000 keypad, or FPC-1000LCD front panel controller—brings you theintuitive interface necessary to control thelargest of systems.

So when looking to put control into those matrixjobs, look to the matrix switcher that deliversunrivaled performance and expandability,without the unrivaled difficulty: the Matrix 6400Video Model.
