1. BNC connector
BNC interface feem ntau yog siv los xa cov teeb liab video, thiab RCA feem ntau yog siv los xa cov suab paj nruag. Txawv interfaces muaj qhov sib txawv zoo thiab ua haujlwm. Tsis tas li ntawd, vim qhov tshwj xeeb tsim ntawm BNC interface, kev sib txuas yog nruj heev, yog li tsis tas yuav txhawj xeeb txog xoob interface thiab kev sib cuag tsis zoo.
BNC connector yog ib qho tshwj xeeb zaub interface txawv ntawm qhov dog dig 15-pin D-SUB txheem connector. Nws yog tsim los ntawm RGB peb thawj xim thiab tsib lub teeb liab ywj pheej connectors rau kab synchronization thiab teb synchronization. Nws yog tsuas yog siv los txuas cov chaw ua haujlwm thiab lwm lub tshuab uas xav tau ntau zaus scanning. BNC connector tuaj yeem cais cov teeb liab tawm tswv yim, txo qhov cuam tshuam ntawm cov teeb liab, thiab lub teeb liab bandwidth loj dua li D-SUB zoo tib yam, uas tuaj yeem ua tiav cov teeb liab teb zoo tshaj plaws.
2. RCA connector
RCA interface paub txog kev sib kis ntawm lub suab thiab yees duab sib cais, zam kev degradation ntawm cov duab zoo los ntawm kev cuam tshuam ntawm cov suab thiab video. Tam sim no, feem ntau siv interface ntawm cov khoom siv audio thiab video, yuav luag txhua cov khoom siv suab thiab video muab qhov kev sib txuas no.
RCA feem ntau hu ua lotus socket. Yuav luag txhua TV thiab DVD players muaj qhov interface no. Nws tsis yog tsim tshwj xeeb rau txhua hom kev sib txuas. Nws tuaj yeem siv rau ob lub suab teeb liab thiab cov teeb liab video zoo tib yam. Nws kuj yog lub qhov (socket) rau cov khoom siv DVD (YCrCb), tab sis tus lej yog peb. RCA connector yog nyob deb ntawm cov suab / video davhlau ya nyob twg. Lub davhlau ya nyob twg ob-xaim tau tsim los ntawm RCA Recording Company thaum ntxov raws li lub sijhawm xov tooj cua. Kuj tseem muaj lub npe qub thiab txawv txawv hu ua "turntable" connector.
RCA davhlau ya nyob twg siv coaxial kis tau tus mob teeb liab, lub hauv paus axis yog siv rau kis tau tus mob teeb liab, thiab lwm yam kev sib cuag txheej yog siv rau hauv av, uas yuav siv tau rau kis tau tus mob ntawm cov suab teeb liab thiab analog video teeb liab. RCA audio terminals feem ntau yog cim ua ke nrog cov xim sib txawv: txoj cai channel yog liab, thiab sab laug channel yog xim dub lossis dawb. Qee qhov xwm txheej, cov kab hauv nruab nrab thiab ib puag ncig cov kab hluav taws xob yog xim coded los pab txhawb kev sib txawv ntawm kev sib txuas, tab sis tag nrho cov RCA connectors hauv tag nrho cov kab ke yog hluav taws xob zoo ib yam. Feem ntau hais lus, RCA stereo suab kab yog ib pawg ntawm sab laug thiab sab xis, thiab txhua lub channel yog ib txoj kab los ntawm qhov pom.
3. Qhov zoo thiab kev ua haujlwm ntawm ob qho tib si
BNC interface feem ntau yog siv los xa cov teeb liab video, thaum RCA feem ntau yog siv los xa cov suab paj nruag. Txawv interfaces muaj qhov sib txawv zoo thiab ua haujlwm. Piv txwv li, BNC connector tuaj yeem txo qhov cuam tshuam ntawm cov teeb liab video thiab ua tiav cov teeb liab teb zoo tshaj plaws. Tsis tas li ntawd, vim qhov tshwj xeeb tsim ntawm BNC interface, kev sib txuas yog nruj heev, yog li tsis tas yuav txhawj xeeb txog xoob interface thiab kev sib cuag tsis zoo. RCA interface paub txog kev sib kis ntawm lub suab thiab yees duab, thiab zam kev degradation ntawm cov duab zoo los ntawm kev sib xyaw suab thiab video cuam tshuam. Tam sim no, feem ntau siv interface ntawm cov khoom siv audio thiab video, yuav luag txhua cov khoom siv suab thiab video muab qhov kev sib txuas no.
