Kanye nje ngo-4K uhlala-8K usendleleni!
Isisombululo se-8K simele iipekseli ezingama-7680 x 4320 (4320p - okanye ilingana ne-33.2 Megapixel). I-8K iphindwe kathathu iinkcukacha ze- 4K kwaye izihlandlo ezili-16 zichazwe ngaphezulu kwe- 1080p .
Kutheni 8K?
Yintoni eyenza i-8K ebalulekileyo kukuba izikrini zeTV zikhudlwana kwaye zikhulu xa uhlala kufuphi ukuze ufumane amava okubheka amanzi, ii-pixels kwiikrini ze-1080p kunye ne-4K zingabonakalisa ukuphazamiseka. Nangona kunjalo, nge-8K, isikrini sifanele sibe sikhulu kakhulu ukuba "siveze" isakhiwo sebonakalayo somfanekiso.
Ngomlinganiselo weenkcukacha ezinikezelwa ngu-8K, nokuba unemizuzwana embalwa ukusuka kwiskrini eninzi i-intshi ezingama-70 okanye ngaphezulu, umfanekiso ubonakala "ungaphantsi kwe-pixel". Ngenxa yoko, i-TV ye-8K igqibelele kwindlela yokubukela i-movie-size yesayizi, kunye nokubonisa iinkcukacha ezintle, ezifana nesicatshulwa kunye neefayile kuma-supervised PC kunye nesibane esikhulu samaphephancwadi e-PC kunye nezibonakaliso zempawu zedijithali.
Imiqobo yokuphunyezwa kwe-8K
Eyona nto ibonakalayo, ingakumbi kwizicelo zobungcali, ukujoliswa kweemakethe zabathengi akulula. Iibhiliyoni zeedola sele zityalwe ngabasasazo, abakhiqizi kunye nabathengi kwezobuchwepheshe bokusasazwa kwe-HDTV njengamanje, ii-TV ze-4K , kunye nezixhobo zendalo, kunye ne- TV ye-4K ukusasazwa ngoku nje , ukufumaneka nokusetyenziswa kwe-8K yindlela ukucima. Nangona kunjalo, emva kweembononongo, kwenziwa amalungiselelo kumhlaba we-8K ojongene nabathengi.
8K kunye noThutho lweTV
Enye yeenkokheli ekuphuhliseni i-8K yokusasazwa kwe-TV yi-NHK yaseJapan ephakamise i-video yayo ye-Super Hi-Vision kunye nefomati yokusasaza njengendlela enokwenzeka. Le fomati yokusasazwa nje kuphela ekuboniseni ividiyo yesisombululo esingu-8K kodwa ingaphinde idlulisele kwii-22.2 iziteshi zomsindo. Iindlela ezingama-22.2 zomsindo zingasetyenziselwa ukuhlangabezana naluphi na uhlobo oluthile olukhoyo okanye oluzayo olufomathiweyo, kunye nokubonelela indlela yokubonelela ngeendlela ezininzi zokulalelwayo zelwimi-eziza kwenza ukusasazwa kwe-TV emhlabeni jikelele.
Njengengxenye yokulungiselela kwabo, i-NHK ihlolisisa i-8K kwindawo yokusasazwa kwe-TV kunye nomnqweno wokugqibela wokubonelela ngezibonelelo zokusakaza ii-8K ze-Olimpiki zase-Tokyo zase-Tokyo ezingama-2020.
Nangona kunjalo, nangona i-NHK inako ukubonelela ngezibonelelo zokusasazwa nge-8K, enye imbambano yindlela abaninzi abasasazo abasasazwayo (njenge-NBC - isasazo se-Olimpiki esisemthethweni se-US) baya kukwazi ukuwadlulisela kunye nababukeli, kwaye ngaba ababukeli bayoba ngu-8K IiTV eziza kubafumana?
8K kunye noxhumo
Ukuze kulungele iimfuno zokuhamba kwee-bandwidth nokudluliselwa kwejubane kwi-8K, ukuxhamla ngokomzimba kwiiTV ezizayo kunye nezixhobo zendalo kufuneka ziphuculwe.
Ukulungiselela oku, inguqu ephuculweyo ye- HDMI (ver 2.1) ifumaneke kubakhiqizi abangabandakanywa nje kwiiTV kunye nezixhobo zendalo kodwa abaguquleli, abahluli , kunye nokwandisa . Isantya sokwamukelwa sisengqiqweni lwabakhiqizi, kodwa kunenjongo yokuba amaTV kunye nabamkeli bemidlalo yasesekhaya ababandakanya le ntuthuko baya kuqala ukuvela kwiithalafu zentengiso ngasekupheleni kuka-2018 okanye ngasekuqaleni kuka-2019.
Ukongezelela kwi-HDMI ephucukisiwe, imilinganiselo emibini yokuxhamla ngokomzimba, i- SuperMHL kunye nePort Port (ver 1.4) iyafumaneka kwakhona kunye ne-8K, ngoko ke qhubeka ukhangelele ezi zikhetho kwii-8K zixhobo, ngakumbi kwi-PC kunye ne-smartphone.
8K kunye nokusasaza
Njengokuba nge-4K, ukusasazwa kwe-intanethi kunokufumana ibhola ehamba phambi kwezinto zombini kunye nokusasazwa kweTV. Nangona kunjalo, kukho ukubamba - Udinga uxhumano lwe-intanethi ngokukhawuleza kakhulu - phezulu kwama-50mbps okanye ngaphezulu. Nangona oku kungenakufikeleleka, qwalasela ukujonga ngokukhawuleza iqela leemiboniso ze-TV zeeyure eziyi-1 okanye iifrimu zeeyure ezingama-2 ziza kudla nayiphi na iifowuni zedatha zenyanga kunye nokugxininisa umgca wendlela ekuthintela amanye amalungu entsapho ekusebenziseni i-intanethi enye ixesha.
Kwakhona, kukho ukungangqinelani okukhulu ngokubhekiselele kwiinketho zokukhawulezisa ezikhoyo kubasebenzisi (kukho iindawo zelizwe apho 50mbps ifisa ukucinga). Ngoko ke, nangona ufuna ukukhupha i-bucks enkulu ye-TV ye-8K, awukwazi ukufikelela kwii-intanethi ezifunekayo ukuze ukhangele nayiphi na into enomxholo oyi-8K.
Oko kuthethwa, zombini i-YouTube kunye neVimeo banikela ngokukhethwa kwevidiyo ye-8K kunye nokukhethwa kwevidiyo. Ewe, nangona kunzima umntu ukuba akwazi ukubukela iividiyo kwi-8K okwangokunje, unokufikelela kwi-4K, 1080p, okanye ukhetho lokusombulula isisombululo esincinane kwimixholo ye-8K enikeziwe.
Nangona kunjalo, xa ii-TV ze-8K ziqala ukufumana indawo kumakhaya ababukeli beTV, i-YouTube kunye neVimeo zilungele, kwaye, sinethemba, ezinye iinkonzo (ngokukodwa ezinikezela ngokusakaza okungama-4K, njenge- Netflix kunye neVudu ), zibandakanyeke, ukuba zinokufikelela kwi-8K -kukhutshwa komxholo.
Iimidlalo ze-8K kunye neVidiyo
Kwi-side side, i-LG, i-Samsung, i-Sharp kunye no-Sony baye batyelela imibukiso yezorhwebo iminyaka emininzi ibonisa iimpawu ze-TV ze-8K, ezithintela kakhulu ingqalelo. Nangona kunjalo, ngowe-2018, akukho nto eye yabetha kwi-market nakubathengi base-US, ngaphandle kwe-$ 4,000 + 32-intshi ye-PC Monitor evela kwiDell. Ngakolunye uhlangothi, i-Sharp ivelisa kwaye ithengise i-TV ye-8-intshi ye-8K eJapan, e-China naseTaiwan, ngokufumaneka kweYurophu ngexesha elithile. Isethi inomlinganiselo wexabiso lase-US elilingana ne-73,000.00.00.
I-8K kunye ne-3D-Free Free ye-TV
Esinye isicelo se-8K sisesithuba se- Glass-Free Free 3D . Ngenani elikhulu lokunyuka kwama-pixel ekusebenzisaneni nalo, ngokudibanisa nobukhulu beetkrini ezinqwenelekayo kwi-3D immersive experience, i-3D ye-3D yeeklasi ezingabonakaliyo ngeeklasi zingaboneleli ngeenkcukacha ezifunekayo. Nangona i-Sharp kunye ne-Samsung zibonise iiprototypes kwiminyaka yamuva, i-Stream TV Networks inikezele ngumbonakaliso obalaseleyo kunje. Iindleko ezinokuthi zibe ngumcimbi wabathengi (kwaye, ngokuqinisekileyo, kukho umbuzo okhoyo umxholo). Nangona kunjalo, i-3D-free 3D ye-glass-free-effect ineempembelelo kwizorhwebo, imfundo, kunye nokusetyenziswa kwezobisi.
8K kunye nokuLondolozwa kweMifanekiso
Enye indawo yokulungiselela ihlabathi le-8K, kusetyenziswe isisombululo se-8K, kunye neendlela zokucoca ngevidiyo, ezifana ne- HDR kunye ne-Wide Color Gamut ekubuyiseleni ifilimu nokuqonda. Ezinye ii-studio zee-movie zithatha iifrikhi ze-classic kwaye zigcinwe njengeifayile zedijithali ze-8K ezingasetyenziswa njengemithombo eqhelekileyo yokufunda kwi-Blu-ray / Ultra HD Blu-ray Disc, ukusasazwa, ukusasazwa okanye ezinye izicelo zokubonisa.
Nangona iifom zangoku eziphezulu ezisetyenziswayo ngoku ziyi-1080p kunye no-4K, ukuqonda ngokuvela kumthombo we-8K kuqinisekisa ukugqithiswa komgangatho ophezulu. Kwakhona, ukuqonda kwi-8K kuthetha ukuba iifilimu okanye enye into ayiyi kulungiswa rhoqo emva kokuba ifomathi entsha yokucacisa ifumaneka kwiimfuno zentengiso okanye zabathengi.
Ngaphantsi
Kungakhathaliseki ukuba banako ukuhambisa nokubonisa iimifanekiso ze-pixel ezi-338 zezombululo kwiiskrini zeTV, isitshixo sokwamkelwa kwayo siya kuba nako ukukwazi ukukwazi ukukwazi ukukwazi ukubonelela kunye nokukwazi ukubonelela ababukeli benomxholo we-8K wangempela. Ngaphandle kokuba ii-studio ze-TV kunye ne-movie zivelise okanye zikhuphe umxholo kwi-8K kwaye zineendawo zokuhambisa (ukusasaza, ukusasaza, okanye isistim sezinto ezibonakalayo), akusayi kuba nefuthe lokwenene kubathengi ukuba baphinde bakhuphe kwizikhwama baze bachithe imali yabo kwi-TV entsha ye-8K , kungakhathaliseki ukuba lixabiso.
Kwakhona, ngelixa isisombululo se-8K sinokusetyenziswa kwiifowuni ezinkulu kakhulu, ukuba ubukhulu beeskrini zingaphantsi kwama-intshi ezingama-70, i-8K iya kuba yinto engaphezulu kwabathengi abaninzi, kwakunye nenyaniso yokuba abathengi abaninzi banolonwabo nge-1080p okanye kwi-4K Ultra HD TVs .
Ngakolunye uhlangothi, abo baphelisa ukugqiba kwi-TV ye-8K ngokukhawuleza xa beqala ukufumaneka kuya kufuneka bahlale bebukele ukujonga izinto ezikhoyo ezingaphezulu kwe-1080p kunye ne-4K malunga nayo yonke into yokubukela iTV kwiminyaka embalwa ezayo, ezinokubonakala zihle kakhulu, kodwa aziyi kuvelisa iqondo elipheleleyo elibukwayo eli-8K.
Njengoko indlela eya kwi-8K ibonisa ukuphuhliswa okukhulu, eli nqaku liya kuhlaziywa ngokufanelekileyo.
