Njengoba nje 4K ihlala - 8K isendleleni!
Isinqumo se-8K simelela amaphikseli angu- 7680 x 4320 (4320p - noma okulingana nama-33.2 Megapixel). I-8K iphindwe izikhathi ezingu-4 ngemininingwane ye- 4K futhi iphindwe izikhathi ezingu-16 ngaphezulu kunezingu- 1080p .
Kungani 8K?
Okwenza 8K kubaluleke kakhulu ukuthi izikrini ze-TV zikhudlwana futhi zikhulu uma uhlala eduze ukuze uthole lokho okubukwayo okubukwayo, amaphikseli ku-skrini engu-1080p no-4K angaba ukuphazamiseka okubonakalayo. Noma kunjalo, nge-8K, isikrini sidinga ukuba sikhulu kakhulu ukuze "siveze" isakhiwo sezithombe ezibonakalayo.
Ngenani lemininingwane ehlinzekwa ngu-8K, noma ngabe unamasentimitha ambalwa kuphela ukusuka esikrinini njengenkulu ngamasentimitha angu-70 noma ngaphezulu, isithombe sibonakala sibe "ngamaphikseli angaphansi". Ngenxa yalokho, i-TV ye-8K iphelele ngisho nokubukwa kwe-movie yobukhulu besidonga, kanye nokubonisa imininingwane enhle, njengombhalo kanye nehluzo kuma-monitor esayizi nkulu amakhulu we-PC kanye nezibonisi zedijithali.
Izithiyo ekusebenzeni kwe-8K
Njengoba kubonakala sengathi, ikakhulukazi izinhlelo zokusebenza, ukubhekisa emakethe yabathengi akulula lokho. Njengoba izigidigidi zamaRandi sezibekwe imali ngabasakazo, abakhiqizi, nabathengi kwezobuchwepheshe bokusakazwa kwe-HDTV njengamanje, ama-TV angu-4K , namadivaysi emithombo, futhi ukusakazwa kwe-TV ye-4K njengamanje kuvele phansi , ukutholakala okubanzi nokusetshenziswa kwe-8K kuyindlela kuvaliwe. Kodwa-ke, ngemuva kwezigcawu, kwenziwa amalungiselelo kumhlaba we-8K othengiwe ngabathengi.
I-8K ne-TV Broadcasting
Omunye wabaholi ekuthuthukiseni i-8K yezokusakaza kwe-TV yi-NHK yaseJapane ephakamise ifomethi yayo ye-Super Hi-Vision njengendlela evamile. Le fomethi yokusakaza ayihlosiwe kuphela ukubonisa ividiyo engu-8K yesinqumo kodwa ingadlulisela ku-22.2 iziteshi zomsindo. Iziteshi ezingu-22.2 zomsindo zingasetshenziswa ukwamukela noma yikuphi ukufometha okuzungezile okukhona noma okuzayo, kanye nokuhlinzeka indlela yokunikeza amathrekhi amaningi alalelwayo alalelwayo - okwenza ukusabalalisa kwe-TV emhlabeni wonke kusebenze ngokwengeziwe.
Njengengxenye yokulungiselela kwabo, i-NHK ihlolisisa i-8K esimweni sokusakazwa kwe-TV nomgomo wokugcina ukuhlinzeka ngemikhiqizo yokusakazwa engu-8K yama-Olympics ase-Tokyo ase-2020.
Kodwa-ke, noma ngabe i-NHK ikwazi ukuhlinzeka ngemikhiqizo yokusabalalisa engu-8K, enye inkinga yilapho abaningi abasakaza abahlanganyeli (njenge-NBC - umsakazo osemthethweni we-Olimpiki wase-US) bazokwazi ukudlulisela kuzo kubabukeli, futhi labo ababukeli bayoba ngu-8K Ama-TV azokwazi ukuthola wona?
8K nokuxhumana
Ukuze uhambisane nezidingo ze-bandwidth nokudluliselwa kwejubane le-8K, ukuxhumeka komzimba kwama-TV azayo kanye namadivayisi omthombo kufanele kuthuthukiswe.
Ukuze ulungiselele lokhu, inguqulo ethuthukisiwe ye- HDMI (ver 2.1) yenziwe itholakale kubakhiqizi abangabandakanyeka kuphela kuma-TV nakumadivaysi omthombo kodwa abashintshi, abahlukanisi , nabandiseli . Isivinini sokwamukelwa siwukuqonda kwabakhiqizi, kodwa kuhloswe ukuthi amathelevishini nezamukeli zaseshashalazini ezihlanganisa i-upgrade bazoqala ukuvela emahalafolini esitolo ngasekupheleni kuka-2018 noma ekuqaleni kuka-2019.
Ngaphandle kwe-HDMI ethuthukisiwe, amazinga amabili okuxhumeka ngokomzimba engeziwe, i- SuperMHL ne-Display Port (ver 1.4) ayatholakala futhi ayisebenzise nge-8K, ngakho-ke qhubeka ukhangele lezi zinketho kumadivayisi angama-8K, ikakhulukazi kwi-PC ne-smartphone.
I-8K neyasakaza
Njengoba nje nge-4K, ukusakaza kwe-intanethi kungase kutholwe ibhola ngaphambi kokubili imidiya yemvelo nokusakazwa kwe-TV. Kodwa-ke, kukhona ukudoba - Udinga uxhumano lwe-intanethi olusheshayo kakhulu - phezulu kwama-50mbps noma ngaphezulu. Nakuba lokhu kungenakufinyeleleka, cabanga ukuthi ukubuka ngokushesha kangakanani iqembu le-TV yamahora angu-1 noma ama-movie amahora angu-2 kuzodla noma yimaphi ama-caps wedatha yenyanga kanye nokubamba ukuhamba komkhawulo okungavimbela amanye amalungu omndeni ekusebenziseni i-inthanethi ngokufanayo isikhathi.
Futhi, kukhona ukungahambisani okuningi ngokuqondene nokukhethwa kwejubane lokusakaza okutholakala kubathengi (kunezindawo ezweni lapho 50mbps ukucabanga okufisa khona). Ngakho-ke, ngisho noma uphakamisa amabhakede amakhulu we-TV ye-8K, ungase ungakwazi ukufinyelela ukuvinjelwa kwe-intanethi okudingeka uyithathe ukuze ubuke noma yikuphi okunikezwayo okuqukethwe okungu-8K.
Lokho okushiwo, kokubili i-YouTube ne-Vimeo inikeza ukukhethwa kwevidiyo ye-8K nokusakaza kokusakaza. Yiqiniso, yize noma ubani engeke akwazi ukubukela amavidiyo ku-8K okwamanje, ungathola ama-4K, 1080p, noma izinketho zokudlala zokunciphisa okuphansi ezitholakala ku-8K okuqukethwe.
Kodwa-ke, uma ama-TV angu-8K eqala ukuthola izindawo kulabo ababukeli be-TV, i-YouTube ne-Vimeo zilungele, futhi, ngethemba, ezinye izinsizakalo (ikakhulukazi ezinikezela ngokusakaza okungu-4K, njenge- Netflix ne- Vudu ), bajoyine, uma nje befinyelela ku-8K okuqukethwe okukhiqiziwe.
Ama-TV we-8K nokubukwa kwevidiyo
Ehlangothini lokubonisa, i-LG, i-Samsung, i-Sharp, ne-Sony beyibukele imibukiso yezohwebo iminyaka eminingana ebonisa ama-prototype angu-8K we-TV, okuheha kakhulu. Kodwa-ke, kusukela ngo-2018, akukho lutho olwenzile emakethe okwamanje kubathengi base-US, ngaphandle kwe-PC $ 4,000 + 32-intshi PC Monitor kusuka kuDell. Ngakolunye uhlangothi, i-Sharp empeleni ikhiqiza futhi ithengise iTV ye-70-intshi ye-8K eJapane, e-China naseTaiwan, ngokulindela ukutholakala eYurophu, ngesikhathi esithile ngo-2018 (ayikho igama kunoma yikuphi ukutholakala kwe-US). Isethi ithwala umthamo wamanani wase-US olingana no- $ 73,000.00.
I-8K ne-3D ye-3D yamahhala ayi-Glass
Olunye uhlelo lokusebenza lwe-8K lungaphakathi isikhala se- Glasses-Free 3D TV . Njengoba inani elikhulu lamaphikseli alandele ukusebenza, ngokubambisana namasayizi amakhulu esikrini afaneleka ekuhlangenwe nakho kwe-3D emzimbeni, ama-TV angama-3D angama-3D angenamalazi angahlinzeka ngemininingwane ejulile nokujula okudingekayo. Nakuba i-Sharp ne-Samsung zombili zibonise iziboniso eminyakeni yamuva nje, i-Stream TV Networks inikeze isibonakaliso esihle kakhulu kuze kube manje. Izindleko ezingahle zibe yinkinga kubathengi (futhi, nakanjani, kukhona umbuzo wokuqukethwe okhona). Kodwa-ke, i-3D engenazibuko eziyi-8K-free 3D inomthelela ekusetshenzisweni kwezohwebo, ezemfundo, kanye nokwelashwa.
Ukulondolozwa kwe-8K nefilimu
Enye indawo yokulungiselela i-World 8K, isebenzisa ukulungiswa kwe-8K, kanye namasu okucubungula ividiyo, njenge- HDR ne-Wide Color Gamut ekubuyiselweni kwefilimu nasekufundiseni. Amanye ama-studio e-movie athatha amafilimu akhethiwe e-classic futhi uwagcina njengamafayela e-digital resolution we-8K angasetshenziswa njengemithombo evamile yokufunda i-Blu-ray / Ultra HD Blu-ray Disc, ukusakaza, ukusakaza noma ezinye izinhlelo zokusebenza zokubonisa.
Ngisho noma amafomethi amanje aphezulu aphezulu-definition asetshenziswa njengamanje ayi-1080p no-4K, ukuqonda kusuka kumthombo we-8K kuqinisekisa ukuthi ukudluliswa kwekhwalithi engcono kunayo yonke. Futhi, ukusebenzisa i-8K kusho ukuthi amafilimu noma okunye okuqukethwe ngeke kulungiswe njalo uma ifomethi entsha yokucacisa ephakeme isebenza kumabhayisikobho noma kubathengi izicelo.
Okubalulekile
Kungakhathaliseki ukuthi ikhono lokudlulisela nokubonisa izithombe ze-pixel ezingu-33k zokulungiswa kwe-pixel ku-screen ye-TV, isihluthulelo sokwamukelwa kwayo sizokwazi ukukwazi ukukwazi ukukwazi nokukwazi ukunikeza ababukeli abanokuqukethwe okungokoqobo okungu-8K. Ngaphandle kokuthi ama-studios we-TV ne-movie akhiqize noma okuqukethwe okuvuselelwa ku-8K futhi abe nezindawo zokusabalalisa (ukusakazwa, ukusakaza, noma ukuxhumana okungokwenyama), ngeke kube khona umgqugquzeli wangempela kubathengi ukuba baphinde babeke emalokishini bese bechitha imali yabo kwi-TV entsha ye-8K , kungakhathaliseki ukuthi inani.
Futhi, ngenkathi isinqumo esingu-8K singase sisebenze kwizicelo ezinkulu zesikrini, ukuze ubukhulu beskrini bungaphansi kwama-intshi angu-70, i-8K izoba ngaphezulu kwabathengi abaningi, kanye nokuthi abathengi abaningi bajabule ngama-1080p noma 4K Ultra HD TVs .
Ngakolunye uhlangothi, labo abaphetha ekunqumeni ukwenza i-TV ye-8K ngokushesha nje lapho beqala ukutholakala kuyodingeka baxazulule ngokubuka okuqukethwe okukhona kwe-1080p no-4K okukhona okwedlula cishe konke ukubukwa kwabo kwe-TV eminyakeni embalwa ezayo, okungase kubonakale kuhle kakhulu, kepha ngeke kuhambisane nesipiliyoni esigcwele se-8K sokubuka.
Njengoba indlela eya ku-8K yembula ukuthuthukiswa okuningi, lesi sihloko sizobuyekezwa ngokufanele.
