Makina Omvera mu Televizioni ndi Dolby Atmos Technology
Kukula kwa wailesi yakanema yamakono sikungoyang'ana kwambiri pa khalidwe la zithunzi zokha. Ngakhale kuti kale chinali chinthu chachikulu chomwe chinkayang'aniridwa kwambiri—kuyambira HD, Full HD, 4K, mpaka 8K—kuwonera tsopano kumadalira kwambiri khalidwe la mawu. Owonera amafuna chidziwitso chozama kwambiri, ngati kuti ali pomwepo pa kanema, masewera, kapena konsati. Apa ndi pomwe Dolby Atmos imayambira, kukhala imodzi mwa njira zamakono zolankhulirana kwambiri za mawu ndipo ikuyamba kugwiritsidwa ntchito m'mitundu yosiyanasiyana ya wailesi yakanema. Dolby Atmos imapereka gawo la mawu lolemera komanso lolondola kuposa makina wamba a stereo kapena mawu ozungulira.
Kodi Dolby Atmos ndi chiyani?
Dolby Atmos ndi ukadaulo wa mawu wochokera ku chinthu womwe umapangidwira kupanga phokoso la magawo atatu. Mosiyana ndi makina amawu ozungulira, omwe amagawa mawu m'njira zinazake (monga 5.1 kapena 7.1), Atmos imagwiritsa ntchito zinthu zamawu ngati "zinthu" zomwe zitha kuyikidwa ndikusunthidwa momasuka mumlengalenga weniweni. Mwanjira imeneyi, mawu amatha kumveka kuchokera mbali zosiyanasiyana, kuphatikiza kuchokera pamwamba, ndikupanga zotsatira zenizeni "za malo".
Mu malo owonetsera mafilimu, Dolby Atmos nthawi zambiri amagwiritsa ntchito ma speaker angapo omwe amaikidwa mozungulira omvera, kuphatikizapo ma speaker a padenga. Komabe, pa wailesi yakanema, zovuta zimakhala zovuta kwambiri: malo ochepa, ma speaker ang'onoang'ono, komanso malo osiyanasiyana a omvera. Komabe, opanga ma TV akupanga njira zosiyanasiyana zokwaniritsira zotsatira za Atmos ngakhale popanda makina onse owonetsera panyumba.
Momwe Dolby Atmos Imagwirira Ntchito pa Televizioni
Kuti wailesi yakanema ipereke Dolby Atmos, iyenera kukwaniritsa zofunikira zingapo: kuthandizira kutanthauzira kapena kufalitsa ma siginecha a Atmos, kukonza mawu, ndi kukonza bwino ma speaker kapena kugwirizana ndi makina akunja amawu.
1. Kuzindikira ndi Kudutsa
Ma TV ena amatha kumasulira ma Dolby Atmos, zomwe zikutanthauza kuti amatha kusintha chizindikiro cha Atmos ndikuchisintha kukhala chotulutsa choyenera cha ma speaker omwe ali mkati. Komabe, ma TV ambiri amangothandizira kupititsa patsogolo, zomwe zikutanthauza kutumiza chizindikiro cha Atmos ku chipangizo china monga soundbar kapena AV receiver kudzera pa HDMI eARC/ARC. Pankhaniyi, TV imagwira ntchito ngati "mlatho" pakati pa gwero la zomwe zili mkati (monga pulogalamu yotsatsira) ndi chipangizo chakunja cha audio.
2. Kukonza Ma Audio ndi Kusintha Ma Virtualization
Popeza ma TV nthawi zambiri samakhala ndi ma speaker apamwamba ngati omwe amapezeka mu ma system a Atmos, opanga nthawi zambiri amagwiritsa ntchito njira zowonera. Ukadaulo uwu umagwira ntchito posintha gawo, ma frequency, ndi kuwunikira kwa mawu kuti akope makutu a wowonera kuti azindikire kuti mawuwo akuchokera mbali inayake. Zotsatira zake sizifanana ndi ma speaker enieni, koma amapereka mawonekedwe otakata kuposa ma stereo system akale.
3. Kapangidwe ka Sipika ya TV
Ma TV apakati mpaka apamwamba nthawi zambiri amakhala ndi ma speaker abwino: ma speaker angapo, subwoofer yomangidwa mkati, kapena ma speaker a mbali kapena apamwamba kuti apange mawonekedwe owala. Ma TV ena amaphatikizanso mapangidwe apadera, monga ma speaker akutsogolo kuti azitha kuyankhula bwino kapena kulekanitsa bwino mawu.
Gwero la Zomwe Zili mu Dolby Atmos
Kupezeka kwa Dolby Atmos pa TV sikutsimikizira zokha kuti zonse zomwe zili mkati zidzamveka ngati "Atmos." Ukadaulo uwu umafuna kuti zomwe zili mkati zipangidwe kapena kulembedwa mu mtundu wa Dolby Atmos. Pakadali pano, magwero odziwika kwambiri a Atmos ndi awa:
- Mautumiki owonera makanema monga Netflix, Disney+, Apple TV+, ndi Prime Video (kutengera dzina, dongosolo lolembetsa, ndi chipangizo).
– Blu-ray ndi Ultra HD Blu-ray nthawi zambiri zimapereka nyimbo za Atmos zamakanema ena.
- Masewera olimbitsa thupi ndi masewera ena amathandizira kutulutsa kwa Atmos kuti mawu azimveka bwino.
Kuphatikiza apo, khalidwe la kulumikizana limagwiranso ntchito. Dolby Atmos ikhoza kuperekedwa kudzera mu Dolby Digital Plus (nthawi zambiri imawonetsedwa) kapena Dolby TrueHD (nthawi zambiri Blu-ray). TV yanu ndi chipangizo chanu chomvera ziyenera kugwirizana ndi mtundu womwe wagwiritsidwa ntchito.
Udindo wa HDMI eARC ndi ARC
Chimodzi mwa zinthu zofunika kwambiri kuti muwonjezere luso la Dolby Atmos ndi kulumikizana kwa mawu. HDMI ARC (Audio Return Channel) imalola TV kutumiza mawu ku soundbar kapena receiver kudzera pa chingwe chimodzi cha HDMI. Komabe, bandwidth ya ARC ndi yochepa, kotero nthawi zina, imangogwira ntchito ku Dolby Digital Plus-based Atmos.
Kuti mukhale ndi khalidwe labwino kwambiri, HDMI eARC (yowonjezeredwa ARC) imapereka bandwidth yokwera, zomwe zimalola kuti mawu otayika amveke mosavuta ngati Dolby TrueHD, kuphatikizapo mtundu wa Atmos wopanda kutaya. Ngati mukufuna chidziwitso chabwino kwambiri cha Atmos kuchokera ku Blu-ray player yanu kapena chipangizo chakunja, kuphatikiza TV yolumikizidwa ndi eARC ndi eARC soundbar/receiver ndikwabwino.
Dolby Atmos kudzera pa TV Internal Speakers: Kodi Ndi Yothandiza Motani?
Funso limodzi lodziwika bwino ndi lakuti: kodi Dolby Atmos pa TV yopanda soundbar imaperekadi zotsatira zake? Yankho lake limadalira zomwe mukuyembekezera komanso kapangidwe ka TV. Ma TV okhala ndi ma speaker wamba nthawi zambiri amakhala ndi zoletsa: kukula kochepa kwa dalaivala, mphamvu yochepa yotulutsa, komanso mtunda wochepa wa ma speaker. Atmos imatha kuwonjezera "kuzindikira malo" ndi kulekanitsa mawu, koma kutalika kwake (mawu ochokera pamwamba) nthawi zambiri sikolimba ngati makina okhala ndi ma speaker enieni.
Komabe, ma TV apamwamba okhala ndi ma speaker amphamvu kapena ma multi-drive audio system ovuta kwambiri angapangitse zotsatira zabwino kwambiri. Opanga ena amaphatikizanso ma automatic calibration omangidwa mkati mwa maikolofoni kuti agwirizane ndi momwe chipinda chilili.

– Malo owonetsera chipinda ndi TV zimakhudza zotsatira zake. Kujambula zithunzi ndi kuwunikira mawu kumagwira ntchito bwino m'zipinda zomwe sizili zotseguka kwambiri komanso zomwe zili ndi malo okwanira owunikira.
Kuphatikiza Kwabwino Kwambiri: Dolby Atmos TV + Soundbar
Kwa ogwiritsa ntchito ambiri, njira yabwino kwambiri yolumikizirana ndi wailesi yakanema ya Dolby Atmos yokhala ndi soundbar ya Dolby Atmos. Ma soundbar amakono nthawi zambiri amakhala ndi ma speaker amphamvu komanso subwoofer yosiyana, zomwe zimapangitsa kuti zikhale zosavuta kuzimitsa komanso kukweza mawu. Kuphatikiza apo, kukhazikitsa kumakhala kosavuta kuposa makina ochitira zisudzo okhala ndi ma speaker ambiri.
Ngati mukufuna mulingo wapamwamba, cholandirira cha AV chokhala ndi mawonekedwe a 5.1.2 kapena 7.1.4 (nambala yomaliza imasonyeza kuchuluka kwa kutalika kwa sipika) chingapereke chidziwitso cha Atmos chomwe chili pafupi ndi sinema, ndithudi chokhala ndi mtengo wokwera komanso zovuta zoyika.
Mapeto
Makina olankhulira pa wailesi yakanema okhala ndi ukadaulo wa Dolby Atmos ndi gawo lalikulu pakukweza momwe anthu amawonera. Atmos imapereka mawu omveka bwino, okhala ndi magawo atatu, owonjezera tsatanetsatane wa mawu komanso opatsa mawonekedwe a kanema omwe kale anali okhudzana ndi makanema kapena malo owonetsera mafilimu apamwamba. Ngakhale kuti zotsatira zomwe zimapezeka kudzera mu ma speaker a TV nthawi zambiri zimadalira mtundu wa chipangizocho ndi njira zosinthira makanema, chithandizo cha Dolby Atmos chikadali chabwino kwambiri - makamaka kwa ogwiritsa ntchito ntchito zowonera makanema komanso okonda makanema.
Kuti mupeze zotsatira zabwino, ndikofunikira kuganizira gwero la zomwe zili mkati, kulumikizana kwa HDMI eARC, ndi zosankha za zida zakunja zamawu monga soundbar kapena AV receiver. Ndi kuphatikiza koyenera, Dolby Atmos imatha kusintha chipinda chochezera kukhala bwalo losangalatsa komanso losangalatsa, komwe mawu samangomveka komanso "amazungulira" wowonera, kuwalowetsa m'nkhaniyo.
