Uma unayo i-Analog TV endala - hlola amanye amathiphu ukuze uwagcine ewusizo
Abathengi abaningi bangaphansi komqondo wokuthi kusukela i-analog kuya ku-DTV Transition eyenzeka ngo-2009, ama-TV anama-analog asakwazi ukusetshenziswa. Nokho, lokho akunjalo neze.
Ukusakazwa kwe-Analog TV - Ukuvuselela Ngokushesha
I-TV ye-Analog yenzelwe ukuthola futhi ibonise izimpawu zomsakazo ezisakazwa ngendlela efanayo esetshenziselwa ukuthunyelwa komsakazo we-AM / FM - ividiyo yathunyelwa ku-AM, ngenkathi umsindo uthunyelwa ku-FM.
Ukuthunyelwa kwe-TV ye-Analog kungaphansi kokuphazanyiswa, njengokuthunjwa neqhwa, kuye ngokuthi ibanga nendawo yendawo ye-TV ethola isignali. Ukuthunyelwa kwe-analog nakho kunciphise kakhulu ngokuvumelana nesinqumo sevidiyo kanye nobubanzi bombala.
Ukusakazwa kwe-TV okugcwele kwamandla e-analog kuphelile ngokusemthethweni ngo-12 Juni 2009. Kungase kube khona amacala ayengaphansi kwamandla, ukusakazwa kwe-TV e-analog kungasatholakala emiphakathini ethile. Kodwa-ke, kusukela ngo-1 kuSeptemba, 2015, lezi zifanele futhi ziyeke, ngaphandle uma imvume ekhethekile yokuqhubeka inikezwa kumnikazi welayisensi wesiteshi esithile yi-FCC.
Ngokushintshwa okuvela ku- analog kuya kokusakazwa kwe-TV ye-digital , ukuqhubeka nokuthola ukusakazwa kwe-TV, abathengi kufanele bathenge i-TV entsha noma baqalise ukusebenza ukuze baqhubeke besebenzisa i-analog TV.
Ukushintshwa akuthintanga kuphela ama-TV anama-analog kodwa ama-VCR kanye nama-DVD angaphambi kuka-2009 ayenamathrekhi akhakhiwe eklanyelwe ukuthola uhlelo nge-antenna ngaphezulu. Ababhalisile bekhamera noma abathintekayo be-TV bangase bathinteke, noma kungenjalo, (ngaphezulu kwalokhu ngezansi).
Izindlela Zokuxhuma i-Analog TV ku-Today & # 39; s Digital World
Uma usenayo i-analog TV futhi okwamanje ingayisebenzisi, ungaphefumula impilo entsha ngenye yezinketho ezilandelayo:
- Uma uthola uhlelo lwe-TV nge-antenna, amabhokisi eguquguqukayo angaphandle we- DTV atholakalayo ukuthi anike amandla ama-TV amadala ukuthi asetshenziswe. Ibhokisi lokuguquguqula le-DTV libekwa phakathi kwe-antenna ne-TV futhi liguqulwa kwisignali engenayo ye-DTV / HDTV kwisignali ye-analog TV evumelana nanoma iyiphi i-TV ye-analog. Ngeke uthole noma yikuphi ukuphakanyiswa okwenziwe kwe-DTV noma i-HDTV nayo yonke izinhlelo ezibukhoma ezibonakalayo zizobonisa njenge-letterboxed (amnyama emaceleni phezulu nangaphansi kwesithombe) kusethi yakho ye-analog.
- Uma ubhalisela isevisi yekhebula / satellite, futhi ibhokisi lekhebula / satellite linikeza umkhiqizo we-analog RF ngokusekela isevisi yesignali ye-analog, ungase ukwazi ukufinyelela izinhlelo. Kodwa-ke, uma ngabe uthola ikhebula elisisekelo ngaphandle kwebhokisi usebenzisa i-analog TV "ekulungele ukwakhiwa kwekhebula," izinsizakalo eziningi zekhebula / satellite azisekho ukunikeza isignali ye-analog TV ngalolu khetho lokuxhuma. Lokhu kusho ukuthi noma ngabe i-analog yakho yakudala i-TV "ikulungele ukukhethwa kwekhebula," manje usungadingeka ukuqasha ibhokisi kumhlinzeki wakho ozofaka izimpawu zekhebula zedijithali emuva ku-analog. Xhumana nesevisi yakho yekhebula noma umhlinzeki we-satellite ukuze uthole imininingwane eyengeziwe.
- Uma i-analog TV ihlanganisa, ngaphezu kokuxhumeka kwe-antenna / ikhebula, isethi (s) se- RCA isitayela se-AV zokufaka (okubomvu, okumhlophe, nokuphuzi) , ungaxhuma ibhokisi lokuguquguquka langaphandle le-DTV noma ibhokisi / i-cable / satellite unenketho yokuxhuma.
- Ukuguqulwa kwe-DTV kuthinta futhi ama-VCR kanye namarekhodi e-DVD (abarekhoda be-DVD okwenziwe ngaphambi kuka-2009) okungenzeka babe ne-tuner eyakhelwe ngaphakathi ukuze bathole uhlelo nge-antenna engaphezu kwe-air kanye namarekhodi e-DVD angafaki i-tuner eyakhelwe ngaphakathi. Kulezi zimo, i-VCR kanye / noma i-DVD yokuqopha idinga ukuxhunywe ebhokisini lokuguqula i-DTV langaphandle noma ibhokisi / ikhebula / satellite ukuze uthole izinhlelo ze-TV zokuqopha izinhloso. Noma kunjalo, kuneminye imikhawulo eyengeziwe .
- Ungakwazi ukuxhuma abanye abasakaza imidiya ku-TV ye-analog eneqoqo lezincomo ze-AV, uma ngabe umsakazo wezindaba abe nesethi yemiphumela ye-analog AV. Lokhu akuvamile, kodwa isibonelo esisodwa yiRoku Express Plus. Le ndlela ivumela ukufinyelela kumasevisi wokusakaza, njenge-Netflix, i-Vudu, ne-Hulu ku-TV yakho yangaphambili ye-analog.
Ngezo zonke izinketho ezingenhla, khumbula ukuthi i-analog TV ingabonisa izithombe kuphela ekuchazeni ukucaciswa okujwayelekile (480i) - ngakho-ke noma ngabe umthombo wohlelo usekuqaleni ku- HD noma i- 4K Ultra HD , uzoyibona nje njengesithombe sokulungiswa okujwayelekile .
Inothi Engeziwe Kubanikazi Bama-HDTV A-2007
Enye into okumele ikhombise ukuthi kuze kube ngu-2007, ngisho nama- HDTV ayengadingeki ukuba abe ne-digital noma i-HD tuner. Ngamanye amazwi, uma une-HDTV yokuqala, ingaba ne-tunog TV kuphela. Uma kunjalo, izinketho ezixhunywe ngenhla nazo zizosebenza, kodwa njengoba ufaka isignali yencazelo ejwayelekile, kuzomele uxhomeke ekutheni ukuphakanyiswa kwe-TV yakho ukuhlinzeka isithombe esihle kakhulu sokubukwa.
Futhi, i-HDTV endala ingase ibe nezimpendulo ze- DVI , esikhundleni sezinhlelo ze- HDMI zokufinyelela izimpawu zokuxazulula i-HD. Uma kunjalo, kuzomele usebenzise ikhebula lokuguqula i-HDMI-to-DVI, futhi wenze uxhumano lwesibili lwe-Audio. Lezi zindlela zokuxhuma zingasetshenziswa nge- OTA HD-DVRs ehambisanayo noma ikhebula le-HD / i-satellite ukuthola uhlelo lwe-HD TV.
Okubalulekile
Uma une-Analog TV endala eseyasebenza, ungase ukwazi ukuyisebenzisa, ugcine ingqondo yamandla akhe okulinganiselwe nezidingo zebhokisi lokuguqula i-DTV ukuze uthole uhlelo lwe-TV.
Ama-HDTV nama-HD HD ama-TV ahlinzekela ngokuqinisekile isipiliyoni esingcono sokubuka i-TV, kodwa uma une-TV ye-analog, ungase ukwazi ukuwusebenzisa "ku-digital age". Nakuba kungakalungi ngempela njenge-TV yakho eyinhloko (ikakhulukazi ekusethelweni kwethempeli ekhaya), i-TV ye-analog ingahle ifaneleke njengesibili, noma i-TV yesithathu.
Njengoba iminyaka idlula futhi ama-TV analokugcina alahliwe ( ngethemba lokuthi aphinde asetshenziswe ) ukukhishwa kwe-TV yesimo se-analog-noma-digital kuyobekwa ukuphumula.
