DIGITAL TELEVISION (DTV) FIELD STRENGTHAND VIDEO QUALITY STUDY
J.WaydeAllen andTedMullen�
A particularconcernaboutdigital television (DTV) broadcastsis whethersuchbroadcastshavesufficientpower to be receivedusinginexpensive indoor antennaslocatedinsidea typical home. To testthis, theInstitute for TelecommunicationSciences(ITS) constructeda “simulatedhome” mountedon a flatbedtrailer. This allowed ITS to move the testhometo a numberof locationsin thevicinity of anoperatingcommercialDTV transmitter. By equippingthis testhomewith commerciallyavailableDTV receiversandan indoor antennalocatedat the centerof the home,ITS could thenobserve andrecordthe DTVreceptionat a numberof test locations. This informationwasfurther correlatedwith the incidentfieldstrengthsby measuringthesignalpower outsidethestructureat a heightof 10 metersabovegroundandat a locationinsidethestructureat a heightof roughly1.5metersaboveground.This reportsummarizestheresultsof this study.

1 INTRODUCTION
As thedeploymentof digital television (DTV) movesforward,a numberof concernshave beenraisedregardingthepower limits placedon thetechnology. Of particularconcernis whetherreceptionof DTV is possibleusingcommer-cially availableDTV receiversandinexpensivesettop or “rabbit-ears”antennaspositionedat arbitrarylocationsin ahome.Sinceover-the-airDTV broadcastsarecurrentlyavailablein anumberof metropolitanareas,onecantestDTVreceptionin a numberof homesites.However, sincehouseslocatedin differentareasareconstructedusinga varietyof materialsandarenot all furnishedthesameway, analysisof suchdatais difficult. Therearesimply too many vari-ables.If no pictureis obtainedat onelocation,how canonedetermineif the lack of receptionis causedby too littlepower, multi-pathinterferencecausedby reflectionsof theDTV signaloff of nearbyobjects,obstructionof thesignalby interveningstructures,interferenceof thesignalby somelocal noisesource,or differencesin theconstructionofthetwo buildings?
Thereareseveral ways that onecandealwith this problem. Oneapproachis to accountfor asmany variablesaspossible. Another is to try and control the numberof experimentalvariablesin order to make the problemmoretractable. For this test, ITS choseto limit the numberof variablesby constructinga simulatedhomethat couldbe moved to a numberof test locations. This eliminatedthe problemof trying to comparedatataken in differentstructuresandallowedITS to look specificallyathow locationandpoweraffectedthereceptionof DTV signalsinsidea structure.

2 THE TEST
2.1 Hardware Requirements
Themajorelementsof thetestsetupinclude:
� SimulatedHomeEnclosure
� VHF/UHF IndoorTV Antenna
� Two CommercialDTV Receivers(differentbrandsandchip sets)
� Digital Camcorder
� TV Monitor
� GPSReceiver
� CalibratedDipole Antenna
� SpectrumAnalyzer
To improve the approximationof the enclosureto a typical house,the structureincludeda window in the broadwall, wasinsulatedwith fiberglass,andwaspaneledwith 1/4 inch plywood. All of theequipmentwasassembledasdiagrammedin Figure1.
Both theindoorTV antennaandthecalibrateddipoleantennacouldbemountedinsidethetestenclosureat thesamelocation. This allowed ITS to positionthe indoor TV antennafor recordingthe DTV receiver’s video signal,or tomeasurethefield strengthat this locationusingthecalibrateddipoleandspectrumanalyzer. Additionally, mountingthesamedipoleantennaon a 10-metermastallowedITS to positionit outsidetheenclosureat a heightof 10 metersabovegroundfor anexternalfield strengthmeasurement.Thisheightapproximatesthelocationof anexternalantennalocatedona representativehome.
2.2 Test Procedure
Thefollowing testprocedurewasfollowedat eachof thelocationswhereobservationsweremade.
1. Parktheteststructureatatestlocation.Theorientationof thestructurewasrandomto theextentthatthevehiclecouldlegally andsafelybeparkedat thechosenlocation.
2. ConnecttheindoorTV antennato thefirst DTV receiver.
3. TunetheDTV receiver to anavailableDTV broadcast.In this case,thestationwasKDVR-Denver, locatedonchannel32with acenterfrequency of 581MHz, andauthorizedto broadcastfrom LookoutMountainin Golden,Colorado,with aneffectiveradiatedpowerof 233kW.
4. Choosethefield strengthindicatordisplayfrom themenuon theDTV receiverandadjusttheantennato obtainthebestsignalasreportedby theDTV receiverdisplay. Theantennaadjustmentswereonly thosebuilt into theantenna,namelyrotationandtilt of the loop element.In all casestheantennalocationremainsconstantat thecenterof thetestenclosure.
5. Recordthevideooutputfrom thefirst DTV receiver.

7. ReplacetheindoorTV antennaonthemountingpostin thecenterof theteststructurewith thecalibrateddipoleantennaconnectedto thespectrumanalyzer. Positionthe dipoleelementsin thesameplaneasthe indoorTVantennaelement.
8. ITS wasinterestedin measuringtheupperlimit of thepowersincethis indicatesthemostpoweroneis likely toseeat the testlocation. Sincethe KDVR signalhasa centerfrequency of 581MHz anda nominalbandwidthof 6 MHz, configuringthespectrumanalyzerwith thefollowing settingstakes601peakpower sampleswith a6-MHz bandwidthcenteredat 581MHz:
� CenterFrequency: 581MHz� Span:0 Hz� SweepTime: 100ms� ResolutionBandwidth:6 MHz� VideoBandwidth:6 MHz� PeakDetector
9. Recordthefield strengthtracedatafrom thespectrumanalyzer.
10. ITS wasalsointerestedin recordingtheshapeof theDTV signalenvelope.Thiswasaccomplishedby reconfig-uring thespectrumanalyzerto provide a narrow band(100kHz) power sweepacrossa frequency rangelarger
3
than the DTV signal bandwidth. This was doneby reconfiguringthe spectrumanalyzerwith the followingsettings:
� CenterFrequency: 581MHz� Span:10 MHz� SweepTime: 100ms� ResolutionBandwidth:100kHz� VideoBandwidth:100kHz� PeakDetector
11. Recordthetracedatafrom thespectrumanalyzerasconfiguredin 10.
12. Mount thedipoleantennaon the10-metermastandraisethemastinto position.
13. Repeatthesamesetof spectrumanalyzermeasurementsat the10-meterheightwith thespectrumanalyzerresetfor the field strengthmeasurementsas in step8. The onedifferenceis that the analyzer’s detectoris set to“peakhold” sothat theanalyzerindicatesthemaximumsignalwhentheantennais rotatedaboutits axis. Thiseliminatestheneedto find theantennapolarizationgiving themaximumsignalbeforetakinga reading.
14. Rotatethedipolemastaroundits axis360degreesandrecordtheresultingfield strengthtrace.
15. Configurethespectrumanalyzerto recordtheshapeof theDTV signalenvelopeaswasdonein step10.
16. Recordthetracedatashowing theDTV signalenvelopeasseenat 10 meters.
17. Recorda descriptionof thetestlocationandtheGPScoordinates.
2.3 Uncertainties
Sincethis reportis anecdotalin nature,a high degreeof measurementaccuracy wasnot expected.Nevertheless,thefollowing shouldgive thereadera reasonableestimateof theexperimentuncertainty.
For our field strengthmeasurementwe measuredthepower of theDTV signalin a 6-MHz bandwidthandcomputedthefield strengthusingtheexpression[1, pg. 9]:
Fs ��� Pmedian � Gcable�� 77 2 � 20log � f ��� Gantenna (1)
where:
Fs is thefield strength� dBµV m� ,Pmedian is themedianpowercomputedfrom thespectrumanalyzertrace � dBm� ,f is thecenterfrequency in MHz (in this casef � 581),
Gcable is thelossof thecableconnectingtheantennato thespectrumanalyzer(in dB), and
Gantenna is thegainof theantenna(in dBi).
4
For ourparticularequipmentour uncertaintiesareestimatedto be:
∆Pmedian ��� 1 dB ��� 26%� (2)
∆Gantenna ��� 2 dB ��� 58%� (3)
∆Gcable ��� 2 dB ��� 58%� (4)
The frequency accuracy given in the spectrumanalyzerdocumentationis � 0 2% of the spanor � 1 2 MHz so thefrequency term canvary from 20log � 579 8� � 55 27 to 20log � 582 2� � 55 30 giving an estimateof ∆20log � f � �� 0 02. Thiscertainlycontributesvery little to theoveralluncertaintyandfor this estimationwill beignored.
Combiningthefractionaluncertaintiesof the∆Pmedian, ∆Gcable, and∆Gantenna termsin anRSSsummationgivesthefollowing estimationfor theType-Bmeasurementuncertainty[2]:
ub ��
∆P2median � ∆G2
cable � ∆G2antenna ��� 0 262 � 0 582 � 0 582 � 0 86 ����� 2 7 dB� (5)
Sincetherearenorepeatdataatany givenpointwith whichto estimateType-Auncertainties[2], this informationmustbeestimatedfrom pastexperience.Similar testingdoneusingtheRadioSpectrumMeasurementSystem(RSMS)hasshown spectrumanalyzermeasurementswith repeatabilityontheorderof � 0 5 dB or approximately� 12%.This is areasonableestimate,andresultsin thefollowing estimateof combineduncertainty
uFs ��
u2a � u2
b � � 0 122 � 0 862 � 0 87 ����� 2 7 dB� (6)
Thisgivesanexpandeduncertaintywith a 95%confidencelimit � k � 2� of
UFs � 2uFs � 1 74 ����� 4 4 dB� (7)
which describesthe“best” measurementaccuracy obtainablewith this testsetup.
3 RESULTS
After collectingdataat eachof thelocations,themedianpeakpowerwascomputedfrom the1.5-meterand10-meterfield strengthtraces(581-MHzcenterfrequency, 0 span,6-MHz resolutionbandwidth).However, sincethis testwasperformedasquickly aspossible,therewerea few instanceswhereourspectrumanalyzertracedatadid notgetsavedto disk. This occurredat locations4, 24,25,26,27,28,29,and30. At theselocationsit wasnot possibleto computea medianandwe were forcedto usethe operator’s handwritten recordof powersreaddirectly from the spectrumanalyzerscreen.Field strengthswerecomputedusingequation1, andtheresultingfield strengthsfrom bothsetsofdataaretabulatedalongwith locationandwhethera television picturewasreceivedon receiver 1 (Rcr 1) or receiver2 (Rcr 2) in Table1. All availabletracedatahasbeenincludedat theendof this documentin AppendixA. A secondsetof datatakena few weekslateris includedin AppendixB. This seconddatasetincludesmeasurementsof therootmeansquare(rms)levelsin additionto thepeakvalues.
A formal quality assessmentof the receivedpicturewasbeyondthe scopeof this experiment.Thedeterminationofwhethera “picture wasreceived” or not wasbasedon thefollowing decisioncriteria: If a receiverwasableto displayapicturefor someportionof theobservationtime,thenthereceptionwasdeemedsuccessfulanda“Y” wasenteredin

thedatatable. If no picturewasseenat all duringtheobservationtime, thenthereceptionwasdeemedunsuccessfulandan“N” wasrecorded.You mayalsonotea few casesindicatingthatdatawasnot available(NA) for receiver 1.This conditionoccurredearly in thetestbeforeit wasdiscoveredthat thereceiver wasnot properlytunedto the testsignal. Consequently, thereareno datain theselocationsto indicatewhetherthis receiver would have pickedup theDTV transmissionor not.
Thetestlocationshavealsobeenoverlayedontopof afield strengthpredictionmapin Figure2. Hereit is importanttonotethatpeakfield strengthsweremeasuredin orderto understandtheupperboundonthereceivedsignal.In contrast,thecomputermodelscomputeaveragefield strengths,andwill indicatea lower predictedfield strength.Oneshouldalsorecognizethat thecomputermodelsassumethat thestation’s transmitpower andantennapatternexactly matchwhatis on record.Confirmationof this would requiretestingat thetransmitter, which for this studywasnot possible.
Finally, thevideoclips recordedfrom thetestreceiverswerealsoeditedto createa DVD recording.This shows therecordedvideofrom eachreceiveroverlaidwith thelocationandfield strengthdataastabulatedin Table1.

4 CONCLUSION
This testprovidesanindicationof how well DTV signalscanbereceivedin theBoulderareafrom anexisting stationlocatedonLookoutMountainandoperatingwith aneffectiveradiatedpowerof 233kW. It alsomakesclearthatpoweraloneis not theonly variableto consider. This is particularlyevidentat location9 (Figures34 - 37) whereno videowasobtainedfrom eitherof thetestreceiverseventhoughthereis asignificantfield strengthat this location.Comparethis for instancewith location19 (Figures74 - 77) wherethereis lessfield strengththanat location9 andvideowasobtainedfrom bothreceivers.Of particularinterestarethedifferencesbetweenthetwo graphsseenin Figure35 andFigure75. Figure35 shows that in spiteof therebeingmorepower at this location,theshapeof theDTV signalhasbeendistorted,presumablyby multi-patheffects,suchthatthereceiveris unableto reconstructthedigital videostreameventhoughthereis morepower availableat this location. Power level is clearlynot theonly importantvariableforthereceptionof DTV.
A muchmorecomprehensive studycould be conductedto help quantify DTV imagequality. Suchan experimentcould look for not only correlationbetweensignalpower andreceivedvideoquality, but alsocorrelationswith suchdeleteriouseffectsasmulti-pathinterference,shielding,andnoise.
