Umhlahlandlela wesinyathelo ngezinyathelo
Ithelevishini yedijithali iletha inkinga ye-antenna-isebenzisa umnikazi we-VCR ukuthi ikhebula ledijithali noma ubhalisile nge-satellite liyazi mayelana nesikhathi esithile - ukulahlekelwa ikhono lokubuka isiteshi esisodwa ngenkathi ubhala enye.
Lena yimibuzo evame kakhulu engizithola kubafundi - indlela yokubuka isiteshi esisodwa ngenkathi ibhala enye. Nakuba lokhu kuyinkinga ye-DTV, inkinga yangempela ayikho ubuchwepheshe bedijithali. Yisimo se-analog ngaphakathi kwe-VCR.
Ngenhlanhla, kunesixazululo kodwa kuzodinga izindleko zezezimali uma ungenayo imishini edingekayo.
Izinto Ezidingekayo
- I-antenna eyodwa
- I-splitter eyodwa-2
- Amabhokisi amabili e- DTV converter (khetha amagama ahlukene)
- I-VCR eyodwa
- Ukushintsha okukodwa kwe-A / B
- Enye ithelevishini
- Ubude obuyisikhombisa bekhebula le-coaxial ngezixhumi ekugcineni
Uma uthola zonke izinto ezidingekayo usulungele ukuxhuma. Sicela ufunde imiyalo bese ubheka lo mdwebo wendimbi ngaphambi kokuqala.
Qaphela: Zonke iziphakamiso kanye neziphumo ezibalwe ngezansi zi-coaxial. Zonke izintambo ezisetshenzisiwe ziyi-coaxial.
Indlela Ama-Components enza ngayo ukuthi ikwazi ukubuka nokurekhoda
Ukuze ubuke isiteshi esisodwa ngenkathi siqopha enye ku-VCR sidinga izibonakaliso ezimbili nama-tuners amabili. Ezinsukwini zakudala ze-analog lokhu kwakungeyona inkinga, ngokusho kwe-Guide.com ye-Home Theater, uRobert Silva.
U-Silva uthe, "Ama-VCR ayenayo i-tuner eyodwa futhi i- RF idlulile . I-RF idlula yiyo evumela ukuthi isignali ihambe ngokuqondile nge-VCR naku-TV ukuze i-tuner ye-TV ingasetshenziselwa ukuhlangana kumzila ohlukile kunesiteshi ukuthi i-VCR iyabhalwa. "
Le nqubo ichazwa kangcono njengokushintshanisa phakathi kwe-TV ne-VCR uma ucindezela inkinobho ye-TV / VCR ekulawuleni okude kweVCR yakho.
Izimpawu zedijithali zinikeza ama-analog tuners ngaphakathi kwe-TV futhi ama-VCR ayinalutho. Yingakho sidinga ibhokisi lokuguqula iDTV. Ibhokisi lokuguqula i-DTV lingakwazi ukucacisa isignali etholakele yi-antenna.
Inkinga yukuthi ibhokisi lokuguqula i-DTV linomshini owodwa we-digital. Ngakho-ke, isignali kuphela esingayibona noma ukurekhoda kunoma yimuphi umguquli we-DTV owodwa odlula kuwo okwamanje.
Yingakho sidinga ukwakha imigudu emibili yesignali. Empeleni, isibopho esivamile kuphela esinesignali ngayinye esabelana ngaso yilowo nalowo uthola i-antenna efanayo futhi uboniswe ku-TV efanayo. Ngaphandle kwalokho, zihlukile.
Faka ukuhlukanisa nokushintsha kwe-A / B.
I-splitter ithatha isignali eyodwa futhi ihlukanisa imigwaqo emibili ehlukene - indlela yesignali A nomzila wesignali B. Ukushintsha kwe-A / B kwenza okuhlukile ngoba kuvumela umsebenzisi ukuthi aguqule phakathi kwamasignali amabili ahlukene ukuze aboniswe kuthelevishini elilodwa. Umshini we-A / B wenza ngendlela efanayo ne-TV / VCR inkinobho ekulawuleni kwakho okude.
Indlela Yokubuka I-One Channel Ngesikhathi Ukuqopha Enye
Zama ukucabangela ukusetha kwakho njengezindlela ezimbili zesignali ezihlukile. Indlela yokubonisa A yi-VCR ne-signal signal B yi-TV.
Ukurekhoda isiteshi uzocindezela inkinobho ethi 'A' ekushintsheni kwe-A / B bese uhlela ibhokisi lokuguquguqula le-A-side esiteshini ofuna ukurekhoda. Bese usethe iVCR yakho ukurekhoda kusiteshi 3 bese ukhetha isikhathi sokurekhoda.
Ngemva kokubeka i-VCR yakho ukurekhoda ucindezela inkinobho ye- 'B' ku-A / B ukuze ubukele i-TV. Ungakwazi ukuvula iziteshi ngokukhululekile ebhokisini lokuguqula i-B-DTV ngenkathi urekhoda ohlangothini A.
Kungcono ukusebenzisa amabhokisi amabili eguquguqukayo e-DTV, njengoba amabhokisi amabili aguquguqukayo e-DTV azobangela ukudideka, futhi kukhona ithuba lokuthi ukulawula okude okude kungakhipha iziteshi kuzo zombili amabhokisi ngesikhathi esifanayo. Uzoqeda lokhu ukukhathazeka ngamabhokisi amabili ahlukene.
- Xhuma ikhebula coaxia kusukela ekuphumeni kwe-antenna kuya kokufakwayo ku-splitter engu-2. Qaphela: Kukhona okukodwa kokufakelwa kwe-coaxial ku-splitter ngakho-ke ungatholi ukuphazamiseka kokungenayo ngemiphumela emibili.
- Xhuma ikhebula le-coaxia kusuka kwenye yeziphumo ku-splitter engu-2 kuya kokufaka kwenye ibhokisi le-DTV converter. Qaphela: Kunemiphumela emibili ku-splitter engu-2 namabhokisi amabili okuguqula i-DTV. Sizosebenzisa okunye okukhiphayo ku-splitter amabili futhi enye ibhokisi lokuguqula i-DTV ku-Isinyathelo 5.
- Xhuma ikhebula coaxial kusuka okukhiphayo ebhokisini lokuqala lokuguqulwa kwe-DTV kuya kokufaka kwi-VCR
- Xhuma ikhebula le-coaxial kusuka ekuphumeni kwe-VCR kuya kulokho okufakwayo okuthiwa 'A' ekushintsheni kwe-A / B
- Xhuma ikhebula le-coaxia kusukela ekuphumeni okungasetshenzisiwe ku-splitter 2-indlela ekufakeni kwebhokisi le-DTV yesibili.
- Xhuma ikhebula coaxia kusukela ekuphumeni kwesikhombisi sesibili se-DTV ebhokisini elibhalwe nge-'B 'ekushintsheni kwe-A / B.
- Xhuma ikhebula coaxial kusuka okukhiphayo okubizwa ngokuthi 'i-TV' ekushintsheni kwe-A / B ekufakweni ku-TV
