Ukuba unomdlalo omdala we-analog TV-khangela ezinye iingcebiso zokugcina zi luncedo
Abathengi abaninzi baphantsi kwengqiqo yokuba ekubeni i-analog ukuya kwi-DTV Transition yenzeke ngo-2009, ii-TV ze-analog zisasasetyenziswa. Nangona kunjalo, loo nto ayikho imeko.
Ukusasazwa kweTV ye-Analog - Ukuhlaziya ngokukhawuleza
Iimvumi ze-Analog zenzelwe ukufumana nokubonisa iimpawu ze-TV ezisasazwayo ngendlela efanelwe ukuhanjiswa kwerediyo ye-AM / FM-i-video idluliselwe kwi-AM, ngelixa i-audio isasazwa kwi-FM.
Ukuhanjiswa kwe-TV ye-Analog kwakuphantsi kokuphazamiseka, njengokugubungela kunye nekhephu, kuxhomekeke kumgama kunye nommandla we-TV ofumana uphawu. Ukuhanjiswa kwe-Analog kwakunqongophe kakhulu ngokubhekiselele kwisisombululo sevidiyo kunye nebala lebala.
Ukusasazwa kwamagqabantshintshi e-analog agcwele ngokusemthethweni kuphele ngo-Juni 12, 2009. Kungenzeka ukuba kukho iimeko eziphantsi kwamandla, ukusasazwa kwe-TV ye-analog kusenokufumaneka kwezinye iindawo. Nangona kunjalo, ngoSeptemba 1, 2015, oku kufuneke kwakhona kuphelelwe, ngaphandle kokuba imvume ekhethekileyo yokuqhubeka ihanjiswe kwisitishi esithile selayisenisi yi-FCC.
Ngokutshintshwa kwe- analog ukuya kwi-TV yedijithali yokusasazwa , ukuqhubeka nokufumana ukusasazwa kwe-TV, abathengi kufuneka bathenge i-TV entsha okanye baqalise ukusebenza ukuze baqhubeke besebenzisa i-analog TV.
Utshintsho oluthe lwachaphazelekayo kuphela kumaTV e-analog kodwa iiVCR kunye ne-2009 yangaphambili ye-DVD ezirekhodiweyo ezenzelwe ukufumana inkqubo nge-antenna. Abathengi be-Cable okanye i-satellites ye-TV banokuchaphazeleka, okanye bangenakuchaphazeleka (ngaphezulu nangaphezulu apha).
Iindlela zokudibanisa i-Analog TV namhlanje ne-# 39; s Digital World
Ukuba unayo i-TV ye-analog kwaye ngoku ungayisebenzisi, unokuphefumla ubomi obutsha kuyo ngenye yezinto ezilandelayo:
- Ukuba ufumana inkqubo yeTV nge-antenna, iibhokisi zenguqu zangaphandle ze- DTV ziyafumaneka ukwenzela ukuba i-TV edala isebenzise. Ibhokisi yokuguqula i-DTV ifakwa phakathi kwe-antenna kunye neTV kunye nokuguqula kwisignali ye-DTV / HDTV engenayo kwisignali ye-analog TV ehambelana nayo nayiphi na i-TV ye-analog. Awuyi kufumana izigqibo ezongeziweyo ze-DTV okanye i-HDTV kunye nayo yonke iprogram ekhulayo iya kubonisa njenge-letterboxed (emnyama imigca phezulu kunye nezantsi komfanekiso) kwisethi yakho ye-analog.
- Ukuba ubhalisa kwi-cable / satellite satellite, kunye nebhodi yekhebula / i-satellite inikezela ngokuphuma kwe-analog ye-analog ngenkonzo yesalathisi ye-analog, unokukwazi ukufikelela kwinkqubo. Nangona kunjalo, ukuba ufumene ikhebula elisisiseko ngaphandle kwebhokisi usebenzisa "i-cable-ready" ye-analog TV, ezininzi iinkonzo zekhebula / i-satelisayizibonelela ngokuveliswa kwezaziso ze-analog ngokusebenzisa le ndlela yokuxhunywa. Oku kuthetha ukuba nangona i-old analog TV yakho "ilungiselelwe ikhefu", ngoku unokufuneka ukuba uyiqeshe ibhokisi kumnikezeli wakho oza kugubungela izibonakaliso zekhebula zedijithali kwi-analog. Qhagamshelana nenkonzo yakho yekhebula okanye umboneleli we-satellite ukuze uthole iinkcukacha ezingaphezulu.
- Ukuba i-TV ye-analog iquka, ngaphezu kwe-antenna / uxhumano lwekhebula, iisethi ze- RCA zesitayela ze-AV izixhobo (obomvu, ezimhlophe, kunye nephuzi) , unokudibanisa ibhokisi yenguqu yangaphandle ye-DTV okanye ibhokisi / i-satellite unokhetho loxhumo.
- Ukuguqulwa kwe-DTV kuchaphazela iiVCR kunye nerekhodi zeDVD (abarekhoda beDVD eyenziwa ngaphambi ko-2009) enokuba ne-tuner eyakhelwe ukufumana iprogram nge-antenna ngaphezulu kwe-air kunye ne-DVD recorders engabandakanyi i-tuner eyakhelwe ngaphakathi. Kule meko, i-VCR kunye / okanye i-DVD irekhodi kufuneka ixhunywe kwibhokisi yenguqu yangaphandle ye-DTV okanye ibhokisi / i-satellite / i-satellite ukwenzela ukufumana inkqubo yeTV yeenjongo zokurekhoda. Nangona kunjalo, kukho ezinye izithintelo ezingaphezulu .
- Unokwazi ukuxhuma abafudumi be- media kwi-TV ye-analog ene-set of AV input, xa i-streamer media ine-setog AV. Oku kunqabile, kodwa omnye umzekelo yiRoku Express Plus. Olu khetho luvumela ukufikelela kwiinkonzo zokusakaza, njenge-Netflix, iVudu, ne-Hulu kwi-TV yakho yangaphambili ye-analog.
Kuzo zonke iinketho ezingentla, khumbula ukuba i-TV ye-analog ingabonisa kuphela imifanekiso kwisisombululo esifanelekileyo (480i) - ngoko nangona umthombo weprogram uqobo kwi- HD okanye i- 4K Ultra HD , uya kuwubona nje ngomfanekiso wesisombululo .
Inqaku elongezelelweyo Kubanikazi bee-HDTV zangaphambi kuka-2007
Enye into ebonisa ukuba kude kube ngo-2007, i- HDTV ayifuni ukuba ne-digital okanye i-HD tuners. Ngamanye amagama, ukuba unayo i-HDTV yangaphambili, inokuthi ibe ne-tunog yeTanor kuphela. Kwimeko apho, ezi zikhetho ezingentla apha ziya kusebenza, kodwa ekubeni unika isalathisi ecacileyo, kufuneka uxhomekeke kwi-TV yakho ye-upscaling ukubonelela umfanekiso ophezulu wokujonga.
Kwakhona, i-HDTV endala ingaba neziphumo ze- DVI , endaweni ye- HDMI iziphumo zokufikelela kwizibonakaliso ze-HD zesisombululo. Ukuba kunjalo, kuya kufuneka usebenzise ikhebula lokuguqula i-HDMI-to-DVI, kunye nokwenza uxhumano lwesibini lwe-Audio. Ezi ndlela zokunxibelelana zingasetyenziselwa i- OTA HD-DVR okanye i-HD ikhebula / iibhokisi ze-satellite zokufumana inkqubo ye-HD TV.
Ngaphantsi
Ukuba unomdala we-analog TV osebenzayo, usenako ukuwusebenzisa, ugcine ingqondo amandla akhe okunciphisa kunye nesidingo sokongeza i-DTV kwibhokisi yokuguqula i-TV.
I-HDTV nee-TV ze-HD zeNkcazo zibonelela ngokuqinisekileyo ngamava okubukela ama-TV angcono, kodwa ukuba unomabonakude we-analog, usenokukwazi ukuwusebenzisa "kwixesha ledijithali". Nangona kungenjalo ngokufanelekileyo njengoko iTV yakho ephambili (ngokukodwa kwi-home-based setup), i-TV ye-analog ingafaneleke ngokufanelekileyo njengesibili, okanye i-TV yesithathu.
Njengoko iminyaka idlulayo kwaye ii-TV zangaphambili ze-analog zigqitywa ( zithemba ukuba ziphinde zenziwe kwakhona ) umba we-analog-okanye-digital ugxininiswe uya kuphumla.
