Vhidhiyo yakafanana ndiyo nzira iyo mavara, B / W, uye Luminance zvikamu zvevhidhiyo yevhidhiyo yeAnalogog inotamirwa pamwe chete kubva kune imwe nzvimbo kuenda kuvhidhiyo rekurekodha (VCR, DVD recorder) kana mavhidhiyo kuratidza (TV, monitor, video projector) . Mavhidhiyo evhidhiyo akafanana analog uye anowanzosanganisira 480i (NTSC) / 576i (PAL) yakazara sarudzo kugadzirisa zviratidzo zvevhidhiyo. Vhidhiyo yakakonzerwa, sezvinoshandiswa mumutengi wemamiriro ezvinhu, haisi yakagadzirirwa kushandiswa pakutumira dhigirii yakakura yeanorog kana yemavhidhiyo emagetsi.
Nhengo yevhidhiyo yevhidhiyo yemavhidhiyo inotumidzwawo seCVBS (Mavara, Video, Blanking, uye Sync kana Muvara, Vhidhiyo, Baseband, Signal), kana YUV (Y = Chiedza, U, uye V = Muvara)
Inofanira kutaridzwa kuti vhidhiyo yakawanda haina kufanana nechiratidzo cheRF chinoshandiswa kubva kune antenna kana bhokisi rebhecheni kumitambo yeTV yeTV iri kushandisa Koaxial Cable - zviratidzo hazvifananidzi. RF inoreva Radiyo Frequency, iyo inoshandiswa inoparidzirwa pamusoro pemhepo, kana kuti inotumidzwa kuburikidza nekambo kana satanho bhokisi kumubatanidzwa wekupindira kwe antenna paTV nekambani kana kuisa-pa-coaxial cable.
The Composite Video Physical Connector
Connectors anoshandiswa pakutumira mavhidhiyo emakwikwi evhidhiyo anouya mumitatu mitatu. Kune unyanzvi hunoshandiswa, guru rekubatanidza rinoshandiswa BNC. MuEurope (mutengi), iyo inowanzozivikanwa ndeye SCART , asi iyo inowanzozivikanwa yekubatanidza inoshandiswa pasi rose ndeye inonzi RCA video connector (inoratidzwa mumufananidzo wakaiswa munyaya ino). RCA Rudzi rwemakwikwi ekubatanidza kambani yemavhidhiyo iyo inowanzoshandiswa inoshandisa pini imwe mukati-kati yakapoteredzwa neyeri yekunze. Iyo inowanzobatana ine imba yeJune inopoteredza kuguma kwekubatanidza kwemaitiro, nyore, chiratidzo.
Vhidhiyo vs Audio
Zvakakosha kucherechedza kuti boka revhidhiyo rinobatanidza rinongotora video. Paunounganidza chinyorwa chine mavhidhiyo evhidhiyo uye ehurukuro, iwe unoda kutumira mutauro uchishandisa imwe connector. Inonyanya kutaurwa audio connector inoshandiswa pamwe chete nechikamu chinonzi video connector inonzi RCA-yakadaro analog stereo connector, iyo inoratidzika seRCA-type composite video connector, asi kazhinji katsvuku uye yakachena pedyo nemazano.
Paunenge uchitenga ra RCA-type composite video cable, iwe ungaita seawa imwe chete, asi kazhinji, inowirirana neketani yematafura anonzi stereo audio. Izvi ndezvekuti izvi zvitatu zvekubatanidza zvinoshandiswa zvakanyanya kuti zvibatanidze mafaira emvura, zvakadai seVCRs, rekodi dzeDVD, Camcorders, uye nezvimwe kuTV kana kuti mavhidhiyo emagetsi.
Iyo yakagadzirwa video inonzi connector ndiyo yekare uye yakanyanya kufanana nehudhiyo yevhidhiyo iyo ichiri kushandiswa. Inogona kuwanika pane dzakawanda mavhidhiyo zvinyorwa uye zviratidzo zvinoratidza, kusanganisira VCRs, camcorders, DVD player, Cable / Satellite boxes, video projors, TVs (kusanganisira HDTVs uye 4K Ultra HD TVs ).
Zvisinei, kubva mugore ra2013 mavhidhiyo akabatanidzwa akaparadzaniswa kubva kuBlu-ray disc players, uye vazhinji vatsva vanodhura mitambo yemavhidhiyo uye vanobudisa nhau vanobvisawo chisarudzo ichi. Kunyange zvazvo zvichinyanya kuiswa pane imwe imba yemitambo yakagamuchirwa, kune zvimwe zvikamu izvo zvakabvisawo kusarudzwa kwekubatanidzwa uku.
Uyewo, pane zvakawanda zveTV dzakagadzirwa kubvira muna 2013, Mavhidhiyo akabatanidzwa mavhidhiyo akaiswa muhutano hwekugoverana ne Component video connections (zvinoreva kuti haugoni kuunganidza zvikamu zvevhidhiyo nemakamu kune mamwe maTV panguva imwechete).
Dzimwe Mhando dzeAnalog Video Connections
S-Vhidhiyo: Zvinotsanangurwa zvakafanana sevhidhiyo yakakonzerwa nekuremekedzwa kweanalogog video kushandiswa maererano nesarudzo, asi inoparadzanisa zviratidzo zveMuvara uye yeLuminance pane zvinobva uye inozvidzokorora pazviratidzwa kana pavhidhiyo yekurekodha. Zvimwe pane S-Video
Component Video: Inoparadzanisa Luminance (Y) uye ruvara (Pb, Pr kana Cb, Cr) muzvikamu zvitatu (zvinoda tambo mitatu) kutenderera kubva kune imwe nzvimbo kuenda kune imwe nzvimbo. Component Video cables inogona kutora zvose zviri zviviri uye yakakwirira-tsanangudzo (kusvika kusvika 1080p) zviratidzo zvevhidhiyo.
