RCA interface

RAC (Radio Corporation of America, RCA) LubRCA connectortau invented.RCA feem ntau hu ua lotus socket, tseem hu ua RAC davhlau ya nyob twg, tseem hu ua RAC interface, yuav luag txhua lub TV, DVD player cov khoom muaj qhov cuam tshuam no.Nws tsis yog tsim tshwj xeeb rau ib qho interface.Nws tuaj yeem siv rau ob qho tib si suab thiab cov yeeb yaj kiab zoo tib yam.Nws kuj yog ib qho DVD tivthaiv (YCrCb) qhov (socket), tab sis tus lej yog peb.RCA feem ntau yog ib khub dawb audio ports thiab daj video ports.Nws feem ntau txuas nrog siv RCA (feem ntau hu ua lotus head), uas yuav tsum tau tsuas yog txuas tus qauv RAC cable nrog lotus taub hau mus rau qhov chaw sib txuas.

Lub teeb liab kis tau tus mob

RCA davhlau ya nyob twg txais yuav coaxial teeb liab kis tau tus mob hom, lub hauv paus axis yog siv rau cov teeb liab kis tau tus mob, thiab txheej sab nrauv yog siv rau hauv av.Nws tuaj yeem siv rau lub sijhawm xws li analog video, analog audio, digital audio thiab chromatic tivthaiv kis.RCA audio terminals feem ntau yog xim nyob rau hauv khub: liab rau txoj cai channel thiab dub los yog dawb rau sab laug channel.Qee qhov xwm txheej, kev sib txuas hauv nruab nrab thiab ib puag ncig cable yog xim-coded los pab txhawb kev xaim, tab sis tag nrho cov RCA connectors thoob plaws hauv lub cev muaj cov hluav taws xob zoo tib yam.Feem ntau hais lus, RCA lub tso suab suab kab yog sab laug thiab sab xis rau ib pab pawg, txhua qhov zoo li channel yog kab.

Lub interface style

Feem ntau ua ke audio ports txoj cai channel (liab) sab laug channel (dawb) thiab video chaw nres nkoj (daj)

Plug style zoo

RAC interface ua rau kev sib cais ntawm lub suab thiab video xa mus, uas tsis txhob muaj cov duab zoo degradation vim lub suab / video hybrid cuam tshuam.Lub interface siv dav tshaj plaws ntawm cov khoom siv suab thiab video, yuav luag txhua lub suab thiab video ntaus ntawv muab qhov kev sib txuas rau lub suab thiab video tawm tswv yim thiab tso tawm.

Qhov tsis zoo

Vim RAC interface kis tau tus mob tseem yog ib tug luminance/chrominance (Y/C) composite video teeb liab, tseem yuav tsum tau mus tso saib cov khoom rau lub teeb/xim sib cais thiab chroma decoding rau imaging, qhov no thawj sib tov dua txheej txheem sib cais yuav inevitably ua rau poob ntawm xim teeb liab. , chroma thiab luminance teeb liab kuj muaj ntau lub caij nyoog los cuam tshuam rau ib leeg los cuam tshuam qhov zoo ntawm cov duab tso tawm zaum kawg.RAC tseem muaj qee lub neej, tab sis nws tsis tuaj yeem siv rau hauv cov xwm txheej uas xav tau kev txwv tsis pub siv vim nws qhov sib xyaw Y / C insurmountable.
