Cov xim ntawm cov duab tso rau hauv lub monitor yog tsim los ntawm peb lub ntsiab xim ntawm R, G, thiab B. Cov phom electron ntawm lub kinescope yog tsim los ntawm peb rab phom ntawm R, G, thiab B. Peb lub LCD panels ntawm lub projector kuj yog tsim los ntawm peb xim R, G, thiab B. Cov kab thiab teb synchronization signals ntawm R, G, thiab B cov cim tau ntxiv rau G teeb liab ua ke. Raws li qhov kev pom zoo ntawm kev ua kom muaj kev sib haum xeeb ntawm cov khoom siv, kev txhawb nqa bandwidth ntawm RGB teeb liab tuaj yeem ncav cuag kaum tawm megabytes.
Yog li ntawd, nws tuaj yeem hais tias RGB teeb liab yog qhov zoo dua li cov xim sib txawv ntawm cov teeb liab, thiab nws yog lub teeb liab ncaj qha heev. RGB cov teeb liab tuaj yeem muab faib ua cov qauv sib txuas thiab sib txuas rau kev sib kis, thiab qhov ua tau zoo ntawm cov teeb liab nce siab dua li ntawm cov teeb liab interlaced. RGB teeb liab siv RCA lub davhlau ya nyob twg ntsaws, Tebchaws Europe siv SCART ntsaws, cov khoom qub siv BNC ntsaws.
RGB teeb liab tuaj yeem muab faib ua peb hom hauv qab no:
RGB+S teeb liab:
Hom teeb liab no yog raws li RGB teeb liab, G teeb liab raug tshem tawm raws li lub teeb liab synchronization, thiab tom qab ntawd cov teeb liab sib xyaw synchronization ntxiv, uas tau muab faib ua plaub kis hauv tag nrho. Cov teeb liab sib xyaw synchronization suav nrog kab rov tav synchronization thiab ntsug synchronization signals. Hom teeb liab no yog siv ntau dua hauv cov khoom qub, thiab BNC plugs feem ntau yog siv.
RGB+Hs, Vs teeb liab
Cov teeb liab no kuj yog raws li RGB teeb liab, thiab cov teeb liab sib xyaw synchronization tau muab faib ua kab rov tav synchronization teeb liab thiab ntsug synchronization teeb liab. Nws feem ntau pom ntawm qub-fashioned peb-phom projectors, feem ntau nrog BNC plugs. Tam sim no, high-end zaub tshaj 17 ntiv tes kuj siv hom davhlau ya nyob twg. Lub khoos phis tawj tso saib siv 15-pin D-hom VGA qhov (socket), uas yog lub luag haujlwm ntawm 5 xov hlau. Cov qub EGA thiab CGA saib xyuas muaj cov kab ntau zaus tsuas yog 15KHz thiab siv 9-pin D-hom interface. Cov kev nce qib RGB scanned+Hs thiab Vs cov cim ntawm cov cuab yeej siv suab-visual niaj hnub yog tso tawm los ntawm VGA davhlau ya nyob twg, uas yog qib siab tshaj plaws ntawm cov teeb liab video thiab tau tshaj lub computer's 640 × 480 daws teeb meem.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm tus saib txuas nrog analog VGA interface thiab lub khoos phis tawj yog tsim cov ntaub ntawv ntawm cov duab duab los ntawm cov txheej txheem digital hauv lub khoos phis tawj, thiab tom qab ntawd cov digital / analog converter hauv daim npav duab hloov pauv peb lub cim xim xim ntawm R, G, B thiab kab thiab teb synchronization Teeb liab, lub teeb liab kis tau mus rau cov khoom siv los ntawm cable.
