Mavidiyo ophatikiza ndi njira yomwe mafilimu a mtundu wa Balo, B / W, ndi Luminance amachotsedwa pamodzi kuchokera ku gwero kupita kujambula kujambula kanema (VCR, kujambula DVD) kapena mavidiyo (TV, monitor, video projector) . Zithunzi zojambulidwa ndi kanema ndi analog ndipo zimakhala ndi 480i (NTSC) / 576i (PAL) zizindikiro zosinthira mavidiyo. Mavidiyo owonetserako, monga momwe amagwiritsidwira ntchito kwa ogula zinthu, sanagwiritsidwe ntchito kugwiritsira ntchito analog yomveka bwino kapena zojambula zamagetsi.
Mtundu wa mavidiyowo umatchedwanso CVBS (Mtundu, Video, Blanking, ndi Sync kapena Color, Video, Baseband, Signal), kapena YUV (Y = Kuwala, U, ndi V = Mtundu)
Tiyenera kutsimikizira kuti mavidiyo ambiri sali ofanana ndi chizindikiro cha RF chimasunthidwa kuchoka ku antenna kapena bokosi la chingwe kumagetsi a TV a RF pogwiritsa ntchito Chingwe cha Coaxial - zizindikiro siziri zofanana. RF imatanthawuza Radio Frequency, zomwe zimagwiritsidwa ntchito pa mlengalenga, kapena zimatumizidwanso kudzera mu chingwe kapena satana bokosi kukulumikiza kwa antenna pa TV pogwiritsa ntchito chingwe kapena cokoxial chingwe.
Composite Video Physical Connector
Zogwiritsira ntchito zomwe zimagwiritsidwa ntchito popititsa zizindikiro zojambulidwa zamagulu zimabwera mu mitundu itatu. Pogwiritsa ntchito akatswiri, mtundu waukulu wa chojambulira ntchito ndi BNC. Ku Ulaya (ogula), mtundu wofala kwambiri ndi SCART , koma mtundu wofala kwambiri wa chojambulidwa ntchito padziko lonse ndi wotchedwa RCA video connector (yosonyezedwa pa chithunzi chomwe chili pamutu uno). Mtundu wa RCA wa kanema wothandizira kanema omwe amagwiritsidwa ntchito nthawi zambiri uli ndi pinini imodzi mkatikati mwazunguliridwa ndi mphete yakunja. Chojambuliracho kawirikawiri chimakhala ndi malo a Yellow omwe akuzungulira chogwirizanitsa chimatha chokhazikika, chosavuta, chizindikiritso.
Video vs Audio
Ndikofunika kuzindikira kuti makina owonetsera kanema amapereka kanema. Mukamagwirizanitsa gwero lomwe liri ndi mavidiyo ndi mavidiyo owonetsera, muyenera kusamutsa mawu pogwiritsa ntchito chida china. Chojambulira chodziwika bwino chogwiritsidwa ntchito mogwirizana ndi kanema kogwiritsira ntchito kanema ndi mtundu wa RCA wa mtundu wa analog stereo, womwe umawoneka ngati mavidiyo a RCA omwe amadziwika nawo, koma kawirikawiri amakhala ofiira ndi oyera pambali pamalangizo.
Mukamagula makina avidiyo a RCA, mungathe kuwagwiritsa ntchito nthawi imodzi, koma nthawi zambiri, muli ndi matepi a audio analog. Izi zili choncho chifukwa zida zitatuzi zimagwiritsidwa ntchito kwambiri pophatikiza zipangizo zamakono, monga VCRs, zojambulajambula za DVD, Camcorders, ndi zina kwa ma TV kapena mavidiyo.
Chojambulira mavidiyo ambiri ndi yakale kwambiri komanso yowonjezera mavidiyo omwe akugwiritsabe ntchito. Zikhoza kupezeka pazipangizo zambiri zowonetsera kanema ndi makina owonetsera, kuphatikizapo VCRs, camcorders, ma DVD, makina a Cable / Satellite, mavidiyo, ma TV (kuphatikizapo HDTVs ndi 4K Ultra HD TV ).
Komabe, kuyambira mu mavidiyo a 2013 awonetsedwe kwa Blu-ray, ndipo ambiri atsopano owonetsera mauthenga ndi mafilimu athandiziranso njirayi. Ngakhale kuti akuphatikizidwanso kumakompyuta ambiri apanyumba, pali zigawo zina zomwe zatulutsanso njirayi.
Komanso, pa TV zambiri zomwe zakhala zikuchitika kuyambira 2013, makonzedwe owonetserako mavidiyo adayikidwa mugawidwe wophatikizana ndi mavidiyo omwe ali ndi mbali (zomwe zikutanthauza kuti simungagwirizane ndi magulu a mavidiyo ndi magulu ambiri pa TV nthawi yomweyo).
Mitundu Yina ya Mavidiyo a Analog
S-Video: Zomwe zimagwiritsidwa ntchito ngati kanema kamene kamakhudzana ndi kanema ka analog pamasulira, koma imalekanitsa chizindikiro ndi mtundu wa Luminance pa gwero ndipo amawakonzanso pawonekera kapena pa kujambula kanema. Zambiri pa S-Video
Video Yophatikiza : Imasiyanitsa Kuwala (Y) ndi mtundu (Pb, Pr kapena Cb, Cr) mumasewu atatu (imafuna zingwe zitatu) kuti zisamuke kuchokera ku gwero kupita ku malo omwe akupita. Makanema a Video omwe ali nawo akhoza kusamutsa onse ofotokoza ndi apamwamba (mpaka 1080p) mavidiyo.
Kwa mafotokozedwe a zithunzi za S-Video ndi Mavidiyo a Composent, komanso SCART, audio stereo audio, ndi ma Foni a RF coaxial, yang'anani pa Nyumba Yathu Yanyumba Zogwirizana Zithunzi Zithunzi .
