Ngati muli ndi TV yakale yakale - onani zowonjezera kuti zikhale zothandiza
Ogulitsa ambiri ali pansi pa kuganiza kuti popeza analog ku DTV Transition inachitika mu 2009, ma TV a analog sangagwiritsidwe ntchito. Komabe, izi siziri choncho.
Kusakaza TV pa Analog - Kubwezeretsa Mwamsanga
Ma TV a Analog anapangidwa kuti alandire ndi kusonyeza zizindikiro za pa TV zomwe zimagwiritsidwa ntchito mofanana ndi ma TV / AM / FM. - kanema kanatumizidwira mu AM, pomwe audio imatumizidwa mu FM.
Mafilimu ojambula ma TV ankanasokonezedwa, monga kutukumula ndi chisanu, malinga ndi mtunda ndi malo omwe TV ikulandira chizindikiro. Kujambula kwa analog kunali kochepa kwambiri ponena za kukonza kanema ndi mtundu wa mitundu.
Mauthenga onse a pa TV a analog anamaliza pa June 12, 2009. Pakhoza kukhala milandu inali yochepa mphamvu, ma TV a analog angakhalebe m'madera ena. Komabe, kuyambira pa 1 September, 2015, izi ziyenera kuti zinathetsedwanso, kupatula ngati chilolezo chapadera chopitiliza kuperekedwa chinaperekedwa kwa mwiniwake wothandizira chithandizo ndi FCC.
Pogwiritsa ntchito kusintha kuchokera ku analog kupita ku wailesi yakanema , kuti apitirize kulandira ma TV, ogula ayenera kugula TV yatsopano kapena kugwiritsa ntchito ntchito kuti apitirize kugwiritsa ntchito TV ya analog.
Kusintha kumeneku sikungakhudze ma TV ya analog koma makanema ndi makina ojambula ma DVD omwe asanakhalepo mu 2009 omwe adapanga mapulogalamu kudzera pa antenna. Olemba ma TV kapena satelesi amawunikira, kapena sangasinthe, (omwe ali pansipa).
Njira Zomwe Mungagwirizanitse TV ya Analog mu Today & # 39; s Digital World
Ngati muli ndi TV ya analog ndipo simukuigwiritsa ntchito, mukhoza kupuma moyo watsopano mwa izo ndi zotsatirazi:
- Ngati mulandira mapulogalamu a pa TV kudzera mu antenna, makina omwe ali kunja kwa DTV alipo omwe amathandiza ma TV akale kuti agwiritsidwebe ntchito. Bokosi logulira DTV laikidwa pakati pa antenna ndi TV ndipo limatembenuza chizindikiro cha DTV / HDTV chomwe chili ndi chizindikiro cha TV ya analog yomwe ikugwirizana ndi TV iliyonse ya analog. Simungapeze malingaliro onse a DTV kapena HDTV ndi mapulogalamu onse awunivesiti adzawonekera ngati lettersboxed (zitsulo zakuda pamwamba ndi pansi pa chithunzi) pazitsulo lanu la analoji.
- Ngati mutumizira ku chingwe / satellite, bokosi / satellite / bokosi limapereka chiwongoladzanja cha RF pogwiritsa ntchito chithunzi cha analog, mungathe kupeza mapulogalamu. Komabe, ngati mwakhala mutalandira chingwe chofunikira popanda bokosi pogwiritsa ntchito "TV yokonzeka", analumikiza ma telefoni / satellite satulutsanso chizindikiro cha analog pogwiritsa ntchito njirayi. Izi zikutanthauza kuti ngakhale ngati TV yanu yakale ya "analog-makonzedwe-makonzedwe", mukhoza tsopano kubwereka bokosi kuchokera kwa wothandizira wanu yemwe adzabwezeretsa zizindikiro zadijito kwa analog. Lumikizanani ndi chithandizo chanu chingwe kapena satelanti kuti mudziwe zambiri.
- Ngati TV ya analog imaphatikizapo, kuwonjezera pa kugwiritsira ntchito antenna / chingwe, zowonjezera za RCA zojambulajambula za AV (zofiira, zoyera, ndi zachikasu) , mukhoza kulumikiza bokosi lakutembenuka la DTV kapena kabati / satellite ali ndi njira yogwirizana.
- DTV Transition imakhudzanso ma VVs ndi zojambulajambula za DVD (zojambulajambula za DVD zomwe zisanachitike chaka cha 2009) zomwe zingakhale ndi chojambulira chokonzekera kuti alandire mapulogalamu kudzera pa antenna yodabwitsa komanso DVD zojambula zomwe siziphatikizapo chojambulira. Pazochitikazi, VCR ndi / kapena zojambula za DVD ziyenera kulumikizidwa ku bokosi lapadera la DTV converter kapena kabati / satana bokosi kuti alandire mapulogalamu a TV pa zolembera. Komabe, pali zina zowonjezera .
- Mukhoza kulumikizana ndi ma TV pa TV ya analoji yomwe imakhala ndi zolemba za AV, zomwe zimapangitsa kuti media broader ikhale ndi zotsatira za zotsatira za analoji. Izi ndizochepa, koma chitsanzo chimodzi ndi Roku Express Plus. Njirayi imapereka mwayi wopeza misonkhano, monga Netflix, Vudu, ndi Hulu pa TV yanu yakale yakale.
Ndi zonse zomwe mwasankha pamwambapa, kumbukirani kuti TV ya analog ingathe kusonyeza zithunzi muyeso yeniyeni yosinthira (480i) - kotero ngakhale pulogalamuyo iliyonse mu HD kapena 4K Ultra HD , mudzawona ngati chithunzi chosinthika .
Mfundo Yowonjezera Kwa Amene Ali ndi Matenda a HIV Pre-2007
Chinthu china chosonyeza kuti mpaka 2007, ngakhale HDTV sinafunikire kukhala ndi digito kapena HD tuners. Mwa kuyankhula kwina, ngati muli ndi HDTV yoyambirira, ikhoza kukhala ndi kanema wa kanema wa analoji. Zikatero, zosankha zapamwambazi zingagwiritsenso ntchito, koma popeza mukupereka chizindikiro choyimira, muyenera kudalira mphamvu yanu ya TV kuti mupereke chithunzithunzi chabwino cha kuwona.
Ndiponso, HDTV yakale ikhoza kukhala ndi zotsatira za DVI , m'malo mwa HDMI zopindulitsa zowonjezera zizindikiro zosinthika za HD. Ngati ndi choncho, muyenera kugwiritsa ntchito chingwe chotembenuza HDMI-to-DVI, komanso kupanga kugwirizana kachiwiri kwa Audio. Zokambiranazi zingagwiritsidwe ntchito ndi OTA HD-DVRs kapena HD chingwe / ma satana omwe amalandira mapulogalamu a HD TV.
Mfundo Yofunika Kwambiri
Ngati muli ndi TV yakale yakale yomwe ikugwirabe ntchito, mungathebe kuiigwiritsa ntchito, mukusunga malingaliro ake osakwanira ndipo mukufunikira kuwonjezera bokosi la DTV loti mulandire mapulogalamu a TV.
Mafilimu a HDT ndi ma TV a HD HD amakupatsani chithunzithunzi chabwino chowonera TV, koma ngati muli ndi TV ya analog, mungathe kuigwiritsa ntchito mu "zaka za digito". Ngakhale kuti siwothandiza kwambiri monga TV yanu yaikulu (makamaka kuwonetserako maofesi a nyumba), TV ya analog ingakhale yoyenera kwambiri ngati yachiwiri, kapena yachitatu ya TV.
Pamene zaka zapitazo komanso TV zotsiriza za analoji zimachotsedwa ( ndikuyembekeza kubwezeretsedwanso ) nkhani ya TV ya analogi-kapena-digito idzapumula.
