Ividiyo edibeneyo yindlela apho imibala yeBakala, i-B / W kunye neLuminance yesignali yevidiyo ye-analog idluliselwa kunye kunye nomthombo wecandelo lokurekhoda kwevidiyo (iVCR, i-DVD recorder) okanye umboniso wevidiyo (iTV, i-monitor, i-video projector) . Iimpawu zevidiyo ezidibeneyo zi-analog kwaye ziqukethe ii- 480i (NTSC) / 576i (PAL) isisombululo esifanelekileyo sokusombulula isignali zevidiyo. Ividiyo edibeneyo, njengoko isetyenziswe kwimeko yomboleki, ayiklanyelwe ukuba isetyenziswe ekudluliseni i-analog yokucacisa ephakamileyo okanye iimpawu zevidiyo zedijithali.
Ifomathi yefayili yevidiyo ebizwa ngokuba yi-CVBS (Umbala, iVidiyo, iVilanking, kunye ne-Sync okanye umbala, iVidiyo, iBanband, uphawu), okanye iYUV (Y = Luminance, U, kunye neV = Umbala)
Kufuneka kuboniswe ukuba ividiyo edibeneyo ayifani neyophawu lwe-RF idluliselwa kwi-antenna okanye kwibhokisi ye-cable kwiimveliso ze-TV ze-RF esebenzisa iCaxial Cable - iimpawu azifani. I-RF ibhekisela kwiRadio Frequency, ebonisa ukuba idluliselwe emoyeni, okanye ilayishwe kwi-cable okanye ibhokisi le-satellite kwisixhumano sokufakelwa kwe-antenna kwiTV nge-screw-on okanye kwi-cable coaxial.
I-Composite Video Physical Connector
Abaxhasi basetyenziselwa ukudlulisela iimpawu zevidiyo ezidibeneyo ziza kwiintlobo ezintathu. Ukusetyenziswa kobuchwephesha, uhlobo olusisiseko lwekhonkco esisetyenziswa yiBNC. EYurophu (umthengi), uhlobo oluqhelekileyo luyi- SCART , kodwa uhlobo oluqhelekileyo lwesalathisi esisetyenziselwa kwihlabathi jikelele libhekiswa njengekhonkco yevidiyo yeRCA (kuboniswe kwisithombe esinyathelwe kweli nqaku). Uhlobo lwe-RCA lwentambo yexubaniso lwevidiyo eluninzi oluqhelekileyo lisetyenzisiwe lunepini enye ngaphakathi ejikelezwe yindandatho yangaphandle. Isixhobo sihlala sinezindlu eziNgcono ezijikeleze umxhasi ekupheleni komlinganiselo, olula, ukuchonga.
IVidiyo vs Audio
Kubalulekile ukuba uqaphele ukuba umxube wevidiyo odibeneyo udlula kuphela ividiyo. Xa udibanisa umthombo onomabonakaliso omabonakude kunye nee-audio, kufuneka udlulise umsindo usebenzisa esinye isixhobo. Isixhobo esiqhelekileyo somculo esetyenziswayo ngokubambisana nekhonkco yevidiyo edibeneyo isalathisi se-analog se-analog stereo, ekhangeleka njenge-RCA-type type connector video, kodwa ngokuqhelekileyo ibomvu nomhlophe kufuphi neengcebiso.
Xa uthengisa ikhebula levidiyo le-RCA-type, ungabakho ngexesha elilodwa, kodwa ngamaxesha amaninzi, lidibene nesethi yamacwecwe e-audio stereo. Oku kungenxa yokuba le ntathu yezonxibelelwano isetyenziswa ngokuqhelekileyo ukuxhuma amacebo omthombo, njengamaVCR, ii-DVD, ii-Camcorders, nokunye kwiiTV okanye iiprojekti zevidiyo.
Umxube wevidiyo oqingqiweyo ngowokudala kunye nolwazi oluqhelekileyo lwexwebhu olusetyenzisiweyo. Iyakwazi ukufunyanwa kwiinkalo ezininzi zemithombo yevidiyo kunye nezixhobo zokubonisa, kubandakanywa iiVCR, ii-camcorders, abadlali beDVD, ii-Cable / Satellite box, iiprojekti zevidiyo, ii-TV (kuquka ii-HDTV kunye ne- 4K Ultra HD TV ).
Nangona kunjalo, ngo-2013 uqhagamshelwano lwevidiyo oludibeneyo luye lwasuswa kwiidlali ze-Blu-ray, kwaye abaninzi abatshabalala be-media media kunye nabasasazo beendaba baye baqeda le ndlela. Nangona kunjalo kuqukwa kwiindawo ezininzi zokufumana izakhiwo zasekhaya, kukho ezinye iiyunithi eziye zaphelisa le ndlela yokuxhunywa.
Kwakhona, kwiiTV ezininzi ezenziwe ukususela ngo-2013, ukudibanisa iividiyo ezidibeneyo ziye zafakwa kwilungiselelo lokwabelana kunye nevidiyo enezixhobo (oko kuthetha ukuba awukwazi ukudibanisa imithombo yevidiyo kunye nenxalenye yeeTV ezininzi ngexesha elifanayo).
Ezinye iintlobo zeevidiyo ze-Analog
I-V-Vidéyo: Iinkcukacha ezifanayo njengevidiyo edibeneyo ngokumalunga nokudluliswa kwevidiyo ye-analog ngokwemigangatho yesisombululo, kodwa ihlukanisa imiqondiso yeMbala kunye neLuminance kumthombo kwaye ibuye ibuyele kwakhona kwisiboniso okanye kwividiyo yokurekhoda. Oku ngakumbi kwi-S-Vidiyo
Ividyo yeVidiyo: Ukwahlula i-Luminance (Y) kunye nombala (Pb, Pr okanye Cb, Cr) kwiimpawu ezintathu (zidinga iintambo ezintathu) zokudlulisa ukusuka kumthombo ukuya kwindawo. Iicandelo zeVidiyo zeVidiyo zingadlulisela zombini umgangatho osemgangathweni kunye nokuphakamileyo (ukufikelela kwi-1080p) iimpawu zevidiyo.
Ukuboniswa kwezithombe ze-S-Vidéyo kunye nokuxhunywa kwevidiyo, kunye ne-SCART, i-audio analog stereo, kunye ne-RF coaxial cable, uqhagamshelane neKhaya lethu leNxibelelwano lweeKhaya .
