Pambuyo pa zaka makumi anayi akuwonerera TV, kufotokoza kwa HDTV kwatsegula chidziwitso cha TV ndi mtundu wabwino komanso tsatanetsatane. Komabe, monga chosafuna chotsatira, palinso otsala ambiri amene akuyang'ana mapulogalamu a televiyo a analog ndi ma VHS akale pa ma TV awo atsopano. Izi zakhala zikudandaula zambiri za khalidwe la zithunzi za analog televizioni ndi mavidiyo a analog pamene akuwoneka pa HDTV.
HDTV: I & # 39; t Nthawizonse Siyang'ana Bwino
Lingaliro lalikulu lopangitsa kulumpha kuchokera ku analog kupita ku HDTV ndiko kupeza mwayi wabwino wopenya. Komabe, kukhala ndi kachilombo ka HIV sikusintha zinthu nthawi zonse, makamaka pakuwona zinthu zosagwirizana ndi HD.
Ndipotu, mavidiyo a analog, monga VHS ndi chipangizo cha analog, nthawi zambiri, amawoneka ovuta kwambiri pa HDTV kuposa momwe amachitira pa televizioni yoyendera.
Chifukwa cha izi ndikuti ma HDTV ali ndi mwayi wowonetsa tsatanetsatane wambiri kuposa TV ya analog, imene mungaganize kuti ndi chinthu chabwino - ndipo, mbali yaikulu, ili. Komabe, HDTV yatsopanoyo sikuti nthawi zonse zimawoneka bwino ngati kanema kasinthidwe kavidiyo ( kamene kamathandizira mbali yomwe imatchulidwa ngati vidiyoyi ikukweza ) imapanga mbali zabwino ndi zoipa za chithunzi chochepa.
Kuyeretsa ndi kuyimitsa chizindikiro choyambirira, zotsatira zabwino zomwe mudzakhala nazo. Komabe, ngati chithunzicho chikukhala ndi phokoso lakumbuyo, kuyimitsidwa kwa chizindikiro, kutuluka kwa mtundu wa magetsi, kapena mavuto a m'mphepete, (zomwe zingakhale zosazindikirika pa TV ya analog chifukwa chakuti ndikukhululukira kwambiri chifukwa cha kusinthika kwapansi) kanema yosinthidwa mu HDTV adzayesera kuyeretsa. Komabe, izi zingapereke zotsatira zosiyana.
Chinthu chinanso chomwe chimapangitsa kuti ma TV a analog awonongeke pa HDTV amadalanso ndi kanema kamene kamagwiritsidwa ntchito ndi opanga mafilimu osiyanasiyana. Ma HDTV ena amachita kutembenuka kwa analog-to-digital ndi ndondomeko ya upscaling bwino kuposa ena. Mukamafufuza ma HDTV kapena ndemanga za HDTVs, lembani ndemanga iliyonse yokhudzana ndi khalidwe la upscaling.
Mfundo ina yofunikira yomwe ikupangidwira ndi yakuti ogulitsa ambiri akukonzekera ku HDTV ( ndipo tsopano 4K Ultra HD TV ) akukonzanso ku kukula kwakukulu kwazenera. Izi zikutanthauza kuti ngati chinsaluchi chikukula, zowonongeka mavidiyo (monga VHS) ziwoneka zovuta kwambiri, mofananamo ndi kuwomba zithunzi zomwe zimapanga maonekedwe ndi m'mphepete mwazomwe zimakhala zochepa. Mwachiyankhulo, zomwe zimawoneka bwino kwambiri pa TV yakale yakale ya 27-inch, siziwoneka bwino pa LCD HD 55 kapena 4K Ultra HD TV, ndipo imagwiranso ntchito pa ma TV aakulu.
Malingaliro Opititsa patsogolo Mafilimu Anu a HDTV Kuwona Zochitika
Pali zochitika zomwe mungatenge zomwe sizidzakuthandizani kukana chizoloŵezi chowonera kanema pa HDTV koma mukawona kusinthako - matepi akale a VHS adzakhala nthawi yochuluka mu chipinda chanu.
- Onetsetsani kuti muli ndi chizindikiro chabwino kwambiri - Ngati muli pa chingwe kapena satana, pita ku Digital Cable, HD Cable, kapena HD Satellite. Ngati muli ndi HDTV yapamwamba kwambiri, bwanji mukuwononga ndalama yanu poipereka ndi chizindikiro chochepa - mumalipira HD - muyenera kukolola mphoto.
- Ngati muli ndi bokosi la HD-HD kapena bokosi la Satellite satana, muziwagwiritsira ntchito ku HDTV pogwiritsa ntchito ma HDMI kapena mavidiyo omwe ali ndi ma Component (mtundu uliwonse wa kugwiritsiridwa ntchito ndi chingwe kapena satana bokosi kuti mutumize HDTV ndi zizindikiro za Digital), osati chikhalidwe kupunthira kapena kukankhira pa RF Connection .
- Imani kujambula ndikusewera matepi a VHS ndikulemba mavidiyo anu a kunyumba kapena TV pa DVD ( ngakhale kuti izi zimakhala zovuta kwambiri chifukwa cha zinthu zingapo ), kapena DVR (makamaka yomwe ili ndi HD) kuchokera ku chipangizo chapafupi kapena satellite. Ndipotu, palinso ma DVRs omwe amawoneka kuti azitha kujambula pulogalamu ya HD TV, monga Channel Master DVR + ndi Nuvyyo Tablo .
Mfundo Yofunika Kwambiri
Kwa iwo amene ali ndi TV ya analog, kumbukirani kuti ma TV onse omwe amatha kufalitsa mafilimu amatha pa June 12, 2009 . Izi zikutanthauza kuti TV yakale sungathe kulandira mapulogalamu onse a TV pokhapokha mutapeza bokosi loyambitsirana kapena lojambulajambula kapena ngati mulembera ku chingwe kapena satelanti, mumabwereka bokosi lomwe liri Analogogoda njira (monga RF kapena Composite video ) yomwe ikugwirizana ndi TV yanu. Zambiri zothandizira chingwe zimapereka bokosi la mini converter pazochitika zotero - tumizani chingwe chanu chapafupi kapena satelanti kuti mudziwe zambiri.
