Bwerezerani magetsi pang'ono mu chizindikiro chanu cha TV
Ngati mumagwiritsa ntchito antenna pakadali pano mwakhala mukuwona kusiyana pakati pa kanema wa analog ndi digito - pulojekiti yowonjezera, nambala zachitsulo ndi mfundo zapamwamba, kugwiritsa ntchito DTV converter box, ndi zina zotero.
Pali kusiyana kwina, kusiyana kosaoneka, ndiko chifukwa cha kutayika kapena kusakanizidwa kulandiridwa ndi pulogalamu yatsopano yomasulira a Federal Communications Commission (FCC).
Ndi chizindikiro cha TV yamagetsi.
Zojambula v. Digital Signal Signal
Chifukwa chodziwikiratu chimodzimodzi, chizindikiro cha TV choterechi sichidzayenda mpaka chizindikiro cha TV ya analog chifukwa zovuta zapadziko lapansi zimakhudza kwambiri kuposa analogog. Zinthu zomwe zimakhudza phwando zimaphatikizapo madenga, makoma, mapiri, mitengo, mphepo, ndi zina zotero.
Chizindikiro chadijito ndi chodziwika kwambiri kuti munthu akuyenda patsogolo pake akhoza kugogoda kunja. Poyerekeza, chizindikiro cha analog chiri ngati roach. Zitenga zambiri kuposa munthu wina akuyenda kutsogolo kwa antenna kuti agwetse chizindikiro.
Makhalidwe abwino ndikuti kuti mupeze chithunzi chabwino cha mlengalenga mukufunikira chizindikiro chabwino cholowa mu kanema wa TV, kaya ali mu TV kapena digiti yotsatila . Vuto ndilo kuti chizindikiro cha kutayika ndikumangirira ndi TV yadijito.
Muzochitika zina, mungathe kuchita zonse bwino koma simukupezabe chizindikiro. Kapena, mungathenso kuwonongeka kwambiri pamene chizindikiro cha digito ya TV chikuyenda kuchokera ku antenna kupita ku tuner.
Mulimonsemo, kukweza kapena kukulitsa mbendera ndiko kukonzekeretsa kulandira kwanu.
Kodi Mukufunikira Kukulitsa?
Njira zofunikira zowonjezera ndizoti muli ndi chizindikiro chopezeka chomwe chikupezeka ndi antenna. Ngati nyamayi imakhala ndi chizindikiro, ndiye kuti kupititsa patsogolo kungakhale chithandizo cha chiwonongeko chapakatikati. Ngati sichikuthandizani ndithu sichidzathetsa vuto lanu.
Kukulitsa chizindikiro cha TV
Kutsindika ndi lingaliro lovuta. Mtsogoleri wamkulu wa AllAmericanDirect.com, Mike Mountford, adalongosola bwino kwambiri pamene anayerekezera kupititsa patsogolo chizindikiro cha TV kuti agwirizane ndi bubu kumapeto kwa phula kuti apange mphamvu yopopera mbewu.
M'nkhani yake, nyenyezi popanda kupititsa patsogolo zili ngati phula ndi kuwala kochokera kumapeto. Pokhapokha, izi zimangokhala zopanda mphamvu pakapopera mbewu, koma pakutha mukhoza kugwiritsa ntchito bubu kuti muwonjezere kuthamanga kwa madzi mwa kuchepetsa kuchuluka kwa madzi kuchokera kumapeto. Phokoso lidzakhala ndi utsi wamphamvu kwambiri kuposa wopanda.
Mu chitsanzo ichi mphutsi ndi amplifier ndi madzi ndi chizindikiro cha digito ya TV. Mphamvu yamagetsi imagwiritsa ntchito magetsi kuti igwire chizindikiro cha TV ndi kutumiza njirayo ndi mphamvu ya magetsi. Izi zimalola chizindikiro cha DTV kuti chiyende patsogolo ndi mphamvu zambiri, zomwe ziyenera kupereka chithunzi chogwirizana.
Kukulitsa sikulingalira kotsimikizirika kwa aliyense wosauka TV pokhapokha zochitika koma ndi njira. Komanso sikokonzekera kuti mupeze chizindikiro cha TV pamene wina salipo-kutanthawuza kuti amplifier sawonjezera kuchuluka kwake kwa antenna. Zimangopereka chizindikiro chotsatira njira yake kuchokera ku antenna kupita ku digito ya digito (TV, DTV converter, ndi zina). Tikukhulupirira, kukakamiza uku kokwanira kuti mupeze chizindikiro chabwino pa TV .
Zamagetsi zowonongeka zimadula zambiri kuposa mankhwala osakanizidwa. Choncho, nthawi zonse ndi bwino kuthana ndi zochitika zina zomwe zingayambitse chizindikiro chosawonongeka musanapite ku sitolo ndikugwiritsa ntchito ndalama zanu pamtundu umene ungakonze kapena kukuthandizani kukalandira kwanu.
Kuthana ndi Mavuto Okulandirira Musanayambe Kuwonetsa Chizindikiro cha TV
Kodi mumagwiritsa ntchito splitter, RF modulator , kapena kusintha kwa A / B ? Izi ndizimene zimagwiritsidwa ntchito, ndipo anthu ambiri amazigwiritsa ntchito, makamaka ngati mukuyesera kuwonerera ndi kujambula njira ziwiri ndi bokosi la DTV.
Vuto ndi iwo ndikuti amachepetsa mphamvu ya chizindikiro cha digito - kutanthauza kuti siwamphamvu kwambiri kusiya gawolo pamene ilo lilowa. Kukulitsa kungapangitse mbendera kuti itheke pamwamba pazing'ono zomwe zigawo zanu zikufunikira kupanga chithunzi chabwino.
Ngati mumagwiritsa ntchito antenna panja , yang'anirani chingwe cha coaxial chomwe chimagwirizanitsa pakati pa antenna ndi mzere kulowa m'nyumba. Chingwe chanu cha coaxial chikhoza kukhala chifukwa cha chizindikiro chosauka chikubwera mnyumbamo.
Kutayika kwa chizindikirochi kumatchedwa kuchepetsedwa, komwe kuli kuyeza kwa kutayika kwa mbendera patali. Pankhani ya zingwe coaxial, tikukamba za RG59 ndi RG6. Mwachidule, RG6 ndi yogwirizana kwambiri ndi digito kuposa RG59.
Mwa kuyankhula kwina, RG59 imateteza kwambiri kapena imakhala ndi chiwonongeko choposa RG6. Cable RG59 ikhoza kukhala chifukwa cha chizindikiro chanu chosauka. Kusintha foni yanu ku RG6 (makamaka RG6 yotetezedwa ndi zida zogwiritsa ntchito golide) ikhoza kukonza vuto lanu lokulandira popanda kugwiritsa ntchito amplifier.
N'zoona kuti kugula chinthu chophweka kungakhale kosavuta kusiyana ndi kusintha kanyumba ka coaxial m'nyumba mwanu.
Nthano yanu yamakono ikhoza kukhala nambala chifukwa cha chithunzi chosauka. Mountford imanena kuti nyenyezi zina zimatha kugwira ntchito mpaka 50% zochepetsera zojambulajambula zamakanema a TV pa v analog.
Malangizo a Mountford pa kafukufuku wa nkhani za antenna ndi zofanana ndi zanga - pitani ku Antenna Web ndipo mugwiritse ntchito chida chawo pa intaneti pofufuza ma TV pa malo anu. Mukhozanso kuyesa kufotokozera antenna, koma musayambe kupita ku Antenna Web kuti mupeze malo enieni omwe mungayankhe.
Kugula Amplifier
Zowonjezera zamagetsi kapena ma TV ndizofala kwambiri mu nyerere, koma mungathe kuzigula ngati malo okhawo. Katundu wamakono kawirikawiri amalengeza amatsitsimula kapena amapatsa antenna. Ngati muwona chiwerengero cha DB ndiye mukudziwa kuti chikuwonjezeka.
Malinga ndi kugula malangizo, monga momwe mungathere pamwamba-kuthirira zomera, mutha kuwonjezera-kukonza digito. Zili zofanana ndi kuyankhula kwa olankhula stereo potulutsa voliyumu kwambiri.
Gawo lovuta ndilovuta kuti muzindikire zomwe ziri zamphamvu kwambiri pa tuner yanu. Akatswiri ena omwe ndalankhula kuti ndiwalimbikitsa kupititsa patsogolo 14db. Ngati mungathe kugula chinthu chomwe chimasintha ma DB.
Ngati mumagula antenna yowonjezereka, onetsetsani kuti mupite ku Antenna Web kuti mutsimikizire kuti muli ndi antenna yoyanjanitsidwa bwino musanagwirizane ndi mphamvu.
