Ividiyo ehlanganisiwe yindlela lapho imibala ye-Color, B / W, ne-Luminance yesignali yevidiyo ye-analog idluliselwa ndawonye kusuka emthonjeni kuya kudivayisi yokurekhoda yevidiyo (i-VCR, i-DVD recorder) noma ukubonisa ividiyo (i-TV, i-monitor, i-video projector) . Izimpawu zomculo eziyingqayizivele zi-analog futhi ziqukethe ama- 480i (NTSC) / 576i (PAL) isinqumo sokujwayelekile sokusungula izimpawu zevidiyo. Ividiyo ehlanganisiwe, njengoba isetshenziselwa imvelo yabathengi, ayiklanyelwe ukuba isetshenziselwe ukudlulisela i-analog yencazelo ephezulu noma imifanekiso yevidiyo yedijithali.
Ifomethi yesignali yevidiyo ehlanganisiwe iphinde ibhekiswe njenge-CVBS (Umbala, iVidiyo, ukuBala, nokuVumelanisa noma Umbala, Ividiyo, iBanband, Signal), noma i-YUV (Y = Luminance, U, neV = Color)
Kumele kuboniswe ukuthi ividiyo ehlanganisiwe ayifani nesignali ye-RF idluliselwa kusuka ku-antenna noma kwibhokisi lekhebula kumibono ye-RF ye-TV esebenzisa i-Coaxial Cable - izimpawu azifani. I-RF ibhekisela ku-Radio Frequency, okuyisignali edluliselwa emoyeni, noma elayishwa ngekhebula noma ibhokisi le-satanethi ekuxhumekeni kokufakelwa kwe-antenna ku-TV nge-screw-on noma ikhebula le-coaxial.
I-Composite Video Physical Connector
Ama-connectors asetshenziselwa ukudlulisa izimpawu zevidiyo ezinhlanganisela eze ngezinhlobo ezintathu. Ukusetshenziswa kochwepheshe, uhlobo oluyinhloko lesikhombisi esisetshenziswa yi-BNC. EYurophu (umthengi), uhlobo oluvame kakhulu yi- SCART , kodwa uhlobo oluvame kakhulu lomxhumanisi osetshenziswa emhlabeni jikelele yilokho okubhekwa njengesikhangiso sevidiyo se-RCA (esiboniswe esithombeni esixhunywe kulesi sihloko). Uhlobo lwe-RCA lwekhebula lexhumano lokuxhumeka kwevidiyo oluvame ukusetshenziselwa lunephini elilodwa phakathi nendawo elizungezwe ngendandatho yangaphandle. Isixhumi ngokuvamile sinezindlu eziphuzi ezizungezile isixhumi sokuphela kokulinganisa, okulula, ukuhlonza.
Ividiyo nomsindo
Kubalulekile ukuthi uqaphele ukuthi umxhumanisi wevidiyo ohlanganisiwe udlula ividiyo kuphela. Uma uxhuma umthombo onomabili womsakazo wevidiyo namazwi, udinga ukudlulisa umsindo usebenzisa esinye isixhumi. Isixhumi somsindo esivamile kakhulu esisetshenziselwa ngokuhlanganiswa ne-video engxenyeni yesikhangisi singumxhumanisi we-analog we-analog stereo, obukeka njengowesixhumi sevidyo sevidiyo e-RCA, kodwa ngokuvamile ngokuvamile obomvu nomhlophe eduze namathiphu.
Uma uthengisa ikhebula levidiyo le-RCA-type, ungaba njengesikhathi esisodwa, kodwa izikhathi eziningi, lihlanganiswe neqoqo lezintambo zomsindo we-analog. Lokhu kungenxa yokuthi le nhlobo yokuxhumeka isetshenziselwa kakhulu ukuxhuma amadivaysi omthombo, njenge-VCRs, amarekhodi e-DVD, ama-Camcorders, nokuningi kuma-TV noma ama-video projectors.
Isixhumanisi sevidiyo esakhiwa yinhlanganisela ye-video endala futhi evamile kakhulu eseyisebenzisayo. Ingahle itholakale kumakhi amaningi wemithombo yevidiyo namadivayisi wokubonisa, kufaka phakathi ama-VCR, amakhamera, abadlali be-DVD, amabhokisi wekhamera / sathethi, ama-video projectors, ama-TV (afaka i-HDTV kanye ne- 4K Ultra HD TV ).
Kodwa-ke, kusukela ngoxhumano lwe-video oluhlanganisiwe ngo-2013 selususwe kusukela kubadlali be-Blu-ray disc, futhi abaningi abadlali be-network media kanye nabasakazwayo bezindaba nabo basuse le nketho. Nakuba ngabe kufakwe emitholampilo eminingi yaseshashalazini yasekhaya, kunezinye izingxenye eziye zaqeda le nketho yokuxhumana.
Futhi, kuma-TV amaningi awenziwe kusukela ngo-2013, ukuxhumeka kwevidiyo okuhlanganisiwe kuye kwafakwa ilungiselelo lokwabelana ngexhumano lwevidyo yevidiyo (okusho ukuthi awukwazi ukuxhuma imithombo yevidiyo engxenyeni neyomthombo kuma-TV amaningi ngesikhathi esisodwa).
Ezinye izinhlobo zokuxhumeka kwevidiyo ye-Analog
I-S-Video: Izincazelo ezifanayo njengevidiyo eyakhiwe ngokuphathelene nokudluliswa kwevidiyo ye-analog ngokuvumelana nesinqumo, kodwa ihlukanisa izimpawu zombala kanye ne-Luminance emthonjeni futhi ibuye uyibuyisele ekubonisweni noma ekuqopheni ividiyo. Okuningi ku-S-Video
Ividyo Eyingxenye : Ihlukanisa i-Luminance (Y) nombala (Pb, Pr noma Cb, Cr) zibe iziteshi ezintathu (kudinga izintambo ezintathu) ukudluliselwa kusuka emthonjeni kuya endaweni. Amakhodi wevidiyo asebenzayo angadlulisa kokubili ukucaciswa okujwayelekile nokuphezulu (kuze kufike ku-1080p) yevidiyo.
Ukuze uthole izinkomba zezithombe ze-S-Video kanye nokuxhumeka kwevidyo yevidyo, kanye ne-SCART, umsindo we-analog stereo, nokuxhumeka kwekhebula le-RF coaxial, hlola i-Home Home Theater Connections Igalari yezithombe .
