Yisiphi isimemo se-RF futhi kungani ungadinga eyodwa
I-DVD yindaba yokuphumelela ye-elektroniki yomthengi. Sekusebenze njengesisusa sokwamukelwa kwemidlalo yaseshashalazini, ukukhulisa ukuthengiswa kwama-TV, izamukeli ezizungezile, izinhlelo zesikhulumi sasekhaya yaseshashalazini, futhi ivule indlela ye-Blu-ray , eyakhokelela ekusungulweni kwe- Ultra HD I-Blu-ray .
Abadlali be-DVD nama-Old Analog TVs
Nakuba abadlali beDVD baklanyelwe ukuba basetshenziswe ku-setups ezihlukahlukene, futhi, kuye ngokuthi umkhiqizo nomodeli banikeza amavidiyo ahlukahlukene amaningi (ama-composite, ama-s-video, izingxenye, i-HDMI) kanye nomsindo (i-analog, i-digital optical / coaxial). , abakhiqizi abazange balandele isidingo sabadlali ukuze bakwazi ukuxhuma kwikhebula elijwayelekile noma ukufakelwa kwe-antenna kumabhayisikobho andala ase- Analog okungenzeka angabi neziphakamiso ezengeziwe zomsindo / zevidiyo.
Ungakhokhisi i-DVD kwi-Analog TV Nge-VCR
Abathengi abaningi baye bazama ukuxhuma isidlali sabo se-DVD ku-VCR bese basebenzisa i-VCR ukudlulisela isignali ku-TV ye-analog, kodwa baye babhekana nekhwalithi yesithombe embi kakhulu nokusimama kwesithombe. Isizathu sokuthi i-DVD player ayikwazi ukuxhumeka ku-TV ngale ndlela ukuthi ama-DVD afakwe ikhodi yobuchwepheshe bokulwa nekhophi ephazamisa ukujikeleza kwe-VCR, okuvimbela abasebenzisi ukuthi basebenzise i-VCR njengendlela "idonsa" yokudlulisa izimpawu ze-DVD ku-TV . Ubuchwepheshe be-anti-ikhophi yingakho ungakwazi ukwenza ikhophi yeDVD kwi-tape ye-VHS noma enye i-DVD ngempumelelo.
Ungaxhuma kanjani isidlali se-DVD ku-TV yakho, uma i-TV yakho ingenayo uhlobo lwezincomo ze-AV ezihambisana nesidlali se-DVD? Okwesibili, ungaxhuma kanjani kokubili i-VCR yakho ne-DVD isidlali sakho se-TV ngesikhathi esifanayo uma i-TV yakho inekhebula elilodwa noma ukufakelwa kwe-antenna?
Isixazululo se-RF Modulator
Impendulo yale mibuzo engenhla ibhokisi elincane elimnyama eliye lahlala iminyaka ebizwa ngokuthi i-RF modulator (Radio Frequency Modulator). Umsebenzi we-modulator we-RF ulula. I-modulator ye-RF iguqula umkhiqizo wevidiyo (kanye / noma umsindo) we-DVD player (noma i-camcorder noma umdlalo wevidiyo) kwisignali yesiteshi 3/4 ehambisana nekhebula le-TV noma okokufaka kwe-antenna.
Kunamamoduli amaningi e-RF ayatholakala, kodwa wonke umsebenzi ngendlela efanayo. Isici esiyinhloko somsunguli we-RF okwenza kube ngokufanelekayo ukusetshenziswa neDVD yikhono layo ukwamukela imiphumela ejwayelekile yomsindo / yevidiyo yomdlali weDVD nokufakelwa kwekhebula (ngisho idluliselwe nge-VCR) kanyekanye.
Ukusetha I-modulator ye-RF Yenzani Ngokuqondile
- Okokuqala: Vele uxhumane nekhebula lakho le-cable / i-VCR ekuxhumekeni kwayo kokufakelwa kwekhebula kwesimo se-RF kanye nomdlali we-DVD ekuxhumaneni kwe- AV yokufakelwa kwe-AV .
- Okwesibili: Xhuma ikhebula elijwayelekile kusuka kumoduli we-RF kuya ku-TV yakho.
- Okwesithathu: Khetha noma isiteshi sesithathu noma 4 esivela ngemuva kweModulator RF.
- Okwesine: Vula i-TV futhi i-modulator ye-RF izothola ngokuzenzakalelayo ukufaka kwekhebula lakho ku-TV. Uma ufuna ukubukela i-DVD yakho isidlali, vele ufake i-TV kusiteshi 3 noma 4, vula i-DVD futhi i-modulator ye-RF izothola ngokuzenzakalelayo isidlali se-DVD futhi izobonisa ibhayisikobho yakho.
Yize kukhona ukungezwani okuncane phakathi kwemikhiqizo ehlukahlukene kanye namamodeli e-RF Modulators i -set up ngokuyisisekelo njengoba kuchaziwe ngenhla .
Ngaphandle kwama-DVD abadlali, ungasebenzisa futhi i-modulator ye-RF ukuxhuma amanye amadivaysi omthombo wevidiyo ku-TV yasendulo ye-analog engenazo izimpendulo ze-AV, ezifana namarekhodi we-DVD, ama-console wegeyimu, ama-media-stream, namakhamera, uma nje lawo madivayisi ube nokuxhumana okujwayelekile kwe-AV kokukhipha. Ama-modulators e-RF awasebenzi nevidiyo yevidiyo noma ukuxhumeka kwe-HDMI.
Ukucutshungulwa okwengeziwe
Uma ungenayo uhlelo lwe-stereo , ibha yomsindo , noma isamukeli sekhaya yaseshashalazini , ungase uhlanganise iziphumo ze-analog stereo ze-DVD kumqhubi we-RF kanye.
Ngokusobala, ngeke uthole izinzuzo zomsindo ozungezile, kodwa uzozwa umsindo ngokusebenzisa izikhulumi ze-TV. Futhi, ngeke uthole izinzuzo ezigcwele zesithombe sekhwalithi seDVD njengoba ukuguqulwa kusuka kwividiyo kuya ku-RF (ikhebula) kunciphisa isinqumo. Kodwa-ke, njengoba ushintsha phakathi kweVCR yakho neDVD uzobona ikhwalithi yesithombe seDVD isaphakeme kunoma yini oyifunayo ku-analog TV yakho.
Futhi, akudingeki ukuthi usebenzise i-modulator ye-RF ukuxhuma isidlali seDVD kumabonakude we-HD ne-Ultra HD njengamanje njengoba inikeza kokubili okukhethwa kukho okungafani (i-composite, ingxenye) kanye ne-HDMI yokufaka ukuxhuma noma yisiphi isidlali se-DVD esinganikezeli uxhumano lwe-HDMI. Okuwukuphela kokukhetha kokuxhumeka okuqedile kuma-TV amasha yi -input ye-S-video .
Kodwa-ke, kubalulekile futhi ukusho ukuthi, ngandlela-thile, zonke izixhumanisi zevidiyo ze-analog zingasuswa ku-Ultra HD TV ngesikhathi esithile. Lesi sihloko sizobuyekezwa ukuze sibonise noma yiziphi izinguquko ezenziwa.
