Compatible IEEE 1394 Devices
CompatibleA/Vdevicesincludesome,butnotall,
cableboxes,D-VHSVCRs,A/Vdiscs,camcorders,and
futureproducts.SomedevicesmayhaveIEEE1394
connectorsbutarenotcompatiblewiththeTV.Areas
ofcompatibilitytoconsiderare:
1. Digital Video Signals
ThisTVcandecodeHDV(high-definitionMPEG2reso-
lution)asprovidedbycableboxesandsomecamcord-
ers.TheTVcannotdecodeDV(standard-definition
resolutionvideo).IftheTVisunabletodecodethe
digitalsignalsuppliedbyyourcamcorder,connectthe
camcordertotheTVusinganalogaudiopluscompos-
itevideo,S-video,orcomponentvideo,oruseHDMI
audio/video.Othertypesofdigitalvideo,suchasPC
videoprovidedbysomecomputers,mustbedecoded
bythesourcedeviceandsenttotheTVasanalog
video,S-video,orDVI/HDMIvideo.
2. Digital Audio Signals
Whenreceivedwithvideosignals,theTVcandecode
DolbyDigitalsignalsandMPEGaudiosignals.
TheTVmaybeunabletopassincompatibledigitalaudio
signalsonthecoaxialdigitalaudiooutput.Thesesignals
maypasstootherdevices,however,onIEEE1394cables.
3. Digital Control Signal
TheTVcanserveasthecontrolcenterforIEEE1394
audio/videodevices,suchasVCRs,A/VDiscs,tuners,
andcableboxesthatarecompatiblewiththefollowing
IEEE1394controlstandards.
• CEA-775. Designedfortuningdevicessuchas
cableboxes,allowingthedevicetosendsimple
graphics.Thisstandarddoesnot,however,allow
theTVtocontrolthecableboxbyIEEE1394.
• AV/C (Audio Video Control). Designedtoprovide
basiccontrolssuchasplay,stop,channelselection,
andvolume,asappropriateforthedevice.
Four-Pin and 6-Pin Connections
Therearetwodifferenttypesofconnectorsusedfor
IEEE1394terminalsandcables:a4-pinanda6-pin
type.Bothtypessendthesamedigitalaudio,video,
andcontrolsignals,butthe6-pinconnectorscan
alsosupplylow-voltageelectricalpowertoconnected
devices.ThisTVusesonly4-pintypeconnectors.
A6-pinconnectorcannotbeconnecteddirectlytoa
4-pinjack,andviceversa.Toconnecta6-pindeviceto
a4-pindevice,usea6-pin-to-4-pinadapteroradapter
cable.Thesecablesareavailablefromelectronicsand
computerstores.
Ifyouwishtoconnecta6-pindevicetotheTV(such
asacamcorder),andthedeviceisdesignedtoreceive
electricalpowerfromanother6-pindevice,thereare
severalwaystoprovideelectricalpowertothedevice:
•
ConnectthecamcorderdirectlytothehouseholdAC.
• Usethecamcorder’sbatteryforpower.
• Connectthecamcorderdirectlytoanother6-pin
deviceinthenetworkthatcanprovidepower.

Direct Device-To-Device Method
TheIEEE1394interfaceallowsyoutochaindevices,
unlikeaudioandvideoconnectionsthatrequireyouto
connecteachindividualdevicedirectlytotheTV.For
example,youcanconnectyourD-VHStoyour1394
A/Vdiscandthenconnectthe1394A/Vdisctothe
TV.TheresultingIEEE1394chainallowsyoutoadd
