Composite video yog ib qho analog hom rau kev hloov cov video signals hauv tus qauv txhais. Ntau cov khoom siv hluav taws xob hauv tsev niaj hnub tseem txhawb nqa cov khoom siv video sib xyaw, yog li koj tuaj yeem txuas koj cov qub DVD / VCR player combo thiab lwm yam khoom siv analog rau koj lub TV ntse.
Cov hom phiaj video sib xyaw kuj tseem hu ua CVBS (xim, Video, Blanking, thiab Sync).
Composite Video yog dab tsi?
Cov kev sib txuas video sib txuas yog qhov qub tshaj plaws thiab feem ntau cov kev sib txuas video uas tseem siv tau. Nws tseem tuaj yeem pom ntawm ntau cov khoom siv video thiab cov khoom siv, suav nrog VCRs, camcorders, DVD players, cable / satellite thawv, video projectors, thiab TVs. Txawm li cas los xij, kev sib txuas video sib txuas tau raug tshem tawm los ntawm Blu-duab tshav disc players thiab feem ntau cov khoom siv streaming tshiab.
Cov teeb liab video sib xyaw yog analog thiab feem ntau suav nrog 480i (NTSC) / 576i (PAL) tus qauv-txhais daws teeb meem video teeb liab. Cov xim, xim dub-thiab-dawb, thiab luminance feem ntawm ib qho analog video teeb liab raug xa mus ua ke los ntawm ib qhov chaw mus rau ib qho chaw kaw video (VCR, DVD recorder) lossis video zaub (TV, saib, video projector). Composite video, raws li siv nyob rau hauv cov neeg siv khoom ib puag ncig, tsis yog tsim los hloov siab txhais analog lossis digital video signals.
Composite Video Connectors
Composite video lossis CVBS inputs tuaj nyob rau hauv peb hom. Rau kev siv, lub ntsiab hom connector siv yog BNC. Hauv Tebchaws Europe, hom ntau tshaj plaws rau cov neeg siv khoom yog SCART, tab sis feem ntau hom connector siv thoob ntiaj teb yog classic RCA video connector. RCA composite video connectors muaj ib tus pin nyob rau hauv nruab nrab ib ncig ntawm lub nplhaib sab nraud. Lub connector feem ntau muaj lub tsev daj rau kev txheeb xyuas yooj yim.
Composite video tsis zoo ib yam li RF (Xov tooj cua zaus) teeb liab uas tau hloov los ntawm tus kav hlau txais xov lossis lub thawv cable siv lub coaxial cable.
Composite Video Connectors thiab Audio Connectors
Composite video connectors tsuas kis tau vis dis aus. Thaum txuas ib lub hauv paus uas muaj ob qho tib si video thiab lub teeb liab, koj yuav tsum tau hloov lub suab siv lwm lub connector. Cov suab nrov tshaj plaws uas siv los ua ke nrog cov khoom sib txuas video yog ib khub ntawm RCA-hom analog stereo connectors, uas zoo ib yam li RCA-type composite video connector tab sis feem ntau yog xim liab thiab dawb nyob ze ntawm cov lus qhia.
Feem ntau TVs tau tsim txij li xyoo 2013 muaj kev sib koom ua ke / cov khoom sib txuas hauv video. Txij li thaum muaj tsuas yog ib qho chaw nres nkoj rau ob qho tib si video thiab suab, koj yuav xav tau lub adapter siv tus qauv RCA-hom cable.
Lwm yam ntawm Analog Video txuas
Lwm cov qauv analog rau kev hloov pauv video suav nrog:
- S-Video muaj qhov tshwj xeeb zoo ib yam li cov yeeb yaj kiab sib xyaw hauv cov ntsiab lus ntawm kev daws teeb meem, tab sis nws cais cov xim thiab cov teeb pom kev zoo ntawm qhov chaw thiab rov ua dua lawv ntawm cov zaub lossis ntawm cov kaw lus video.
- Component video cais luminance thiab xim rau hauv peb raws. Cov khoom siv video cables tuaj yeem hloov tau ob qho tib si tus qauv thiab cov ntsiab lus siab (txog 1080p) video signals.
