Iyini i-HDR ku-TV, amamodeli ayisekelayo nokuthi ubuchwepheshe bunikwa amandla kanjani

I-HDR (High Dynamic Range) ku-TV iyisici ozikhethela sona esisho ikhwalithi yesithombe esihle uma ubuka amamuvi. Ubuchwepheshe be-HDR obusetshenziswa kuma-TV anamuhla buguqula ikhwalithi yesithombe osibukayo. Imibala esikrinini iba sobala nakakhulu, futhi isithombe ngokwaso – semvelo. Isici se-HDR kuma-TV sikuvumela ukuthi ubonise izithombe ezinobubanzi obubalulekile bethoni, ukuze ujabulele imininingwane yezigcawu ezimnyama nezikhanya kakhulu.

Iyini i-HDR ku-TV, Izinzuzo Zebanga Elinamandla Eliphezulu

Imodi ye-HDR ku-TV yenza isithombe sibe ngokoqobo ngokwengeziwe, okunikeza umbukeli umuzwa omuhle kakhulu lapho ebuka amamuvi noma izinhlelo eziyintandokazi. Imibala egqamile yenza ukubuka okufanayo neminye imisebenzi yezemidlalo kube mnandi kakhulu. Isistimu ye-HDR kuma-TV ayifani ngaso sonke isikhathi. Amamodeli atholakala emakethe ayahluka ngekhwalithi yesithombe (i-HDR 10, HDR 10+, HLG ne-Dolby Vision ayatholakala). Izinzuzo zokusekelwa kwe-hdr ku-TV:

1. Lolu khetho lunikeza imibala ecebile kanye nokugqama okubukhali.
2. I-4K TV ehlanganiswe ne-HDR ivumela abasebenzisi ukuthi bajabulele ukunyakaza okushelelayo nemifanekiso engokoqobo.

Kuyaphawuleka ukuthi izigcawu ezivezwa esikrinini ziwumfanekiso walokho okubonwa iso lomuntu. I-shades eminingi yombala ngamunye iyatholakala, okwenza isithombe sibe semvelo.

Imodi ye-HD ku-TV iwusizo ikakhulukazi ekubukeni okurekhodiwe kwemvelo namafilimu ashuthwe ngemishini yokukhiqiza yekhwalithi ephezulu kakhulu. Ama-hues ahlala efana, ngakho-ke amagrey, amnyama neminye imibala aqinile, akhanyayo futhi acacile kakhulu. [i-id yamagama-ncazo = “okunamathiselwe_2866″ align=”aligncenter” wide=”512″]

Imaphi ama-TV asekela i-HDR

Kunama-TV amaningi e-HDR atholakala emakethe. Kodwa-ke, lapho ukhetha, kufanele ugxile kumingcele ebaluleke kakhulu ukuze ujabulele ikhwalithi yesithombe engcono kakhulu. I- HDR +
i- Samsung Smart TV iyinhlanganisela ephelele yolwazi olujulile lapho ubuka amamuvi noma udlala imidlalo. Futhi emakethe kunamamodeli alandelayo e-Smart TV asekela ububanzi obuguquguqukayo obunwetshiwe:

1. Ama- Samsung TV azoba wusizo kuqala kukho konke kubasebenzisi abathanda imidlalo namafilimu amangalisayo. Izinga elihle kakhulu lihambisana nenani elifanele, futhi imiphumela ibonakala kakhulu ngenxa yokukhanya okungemuva kwe-FALD ye-multi-zone.
2. Amamodeli e-Toshiba angama-TV athengekayo avame ukusekela i-HDR10 ne-Dolby Vision. Ngenxa yenani lawo eliphansi, awukwazi ukulindela imiphumela ekhangayo kubo, njengoba kunjalo ngamamodeli abiza kakhulu, kodwa umehluko wekhwalithi ye-HDR ubonakala ngokubuka nje.
3. Ama -TV akwaSony ahambisana ngokugcwele ne-PlayStation 5. Asebenzisa ukukhanya okungemuva kwezindawo eziningi. Ungakhetha kumamodeli ane-Dolby Visi, i-HDR 10 ne-HDR 10+, ngenxa yalokho imiphumela ngesikhathi sokubuka izokwanelisa ngisho nabasebenzisi abafuna kakhulu.
4. I- Panasonic inikeza ama-TV angu-65-intshi aqinisekisa ikhwalithi ephezulu nokulindelwe okuphezulu kwezici ze-HDR. Imibala egqamile idinga ukunakwa, ngakho yonke imuvi oyibukayo ikunikeza umuzwa ongenakulibaleka kanye nekhwalithi yesithombe ehamba phambili.

Amafomethi e-HDR atholakalayo

I-HDR (High Dynamic Range) ihumusha ngokwezwi nezwi ngokuthi “ububanzi obunamandla obuphezulu”, okuthi, ngakolunye uhlangothi, buhambisane nomqondo wobuchwepheshe, kodwa ngakolunye uhlangothi, buwunciphisa kakhulu. Okubaluleke kakhulu kulo mongo ububanzi bethoni yesithombe. I-HDR ikuvumela ukuthi ubuke izinhlobo ezihlukene zokuqukethwe ngekhwalithi okunokwanda okusabalala phakathi kwamaphoyinti alula kakhulu namnyama kakhulu. Ngenxa yalokho, imibala iyagqama, ithatha isimo esingokwemvelo, futhi imininingwane iba bukhali. Lokhu kubonakala ikakhulukazi ezigcawini ezimnyama ngokwazo kodwa ezinamachashaza akhanyayo. Njengoba kunamazinga amaningana we-HDR emakethe, kubalulekile ukwazi ukuthi ahluka kanjani, yiziphi izinketho ezidingwa yimishini yethu ukuze sikwazi ukuzisebenzisa:

1. I- HDR10 ifomethi ye-HDR eyisisekelo futhi isekelwa yibo bonke abakhiqizi besikrini be-TV noma abanye abasakazi (ayikho ilayisense edingekayo kulokhu). Ifomethi ye-HDR10 isebenzisa i-gamut yombala we-10-bit (imibala engu-1024 uma iqhathaniswa no-220 kuma-TV ajwayelekile).
2. I- HDR10+ iyifomethi ethuthukisiwe ngokuya ngemethadatha esetshenzisiwe – iyashintshashintsha. Umbhalo wekhodi usekelwe ebangeni lemibala engu-12-bit (amanani ombala angu-4096), okunikeza imiphumela engcono nakakhulu kune-HDR10 eyisisekelo. Umehluko usekugcineni idatha (ngefomethi ye-Dolby Video, ifremu ngayinye iyifayela elihlukile). Kubalulekile ukuqaphela ukuthi uma lobu buchwepheshe busekelwa, intengo ye-TV iyakhuphuka.
3. IHybrid Log Gamma ifomethi ye-HDR eyakhiwe yiBritish BBC (British Broadcasting Corporation) ngokubambisana ne-NHK, umsakazi kazwelonke wase-Japan.

ukubukwa kwe-HDR[/caption]

Inkinga ngama-TV endabuko ukuthi iningi lababukeli bawo lisabambelele kuma-SDR TV amadala angakwazi ukubonisa izinga le-HDR elivame ukwanda.

I-SDR nayo ishibhile ukwenza ifilimu, futhi i-BBC ithandabuza ngokwemvelo ukushiya ifomethi engabizi amashumi ezinkulungwane zababukeli abasathembele kuyo. Ifomethi ye-HLG inqoba lesi “sithiyo” ngokufaka ikhodi yolwazi lwe-HDR ne-SDR kusignali eyodwa, okuvumela ama-TV asebenzisana ne-HDR ukuthi abonise isithombe esithuthukisiwe. I-Hybrid Log Gamma isebenzisa lokho okwaziwa ngokuthi “i-opto-optical transmission function”, okuyinqubo esetshenziselwa ukuguqula isignali yokusakaza ibe ukukhanya okuboniswa kusikrini sakho se-TV.

Yini oyidingayo ukuze ujabulele ikhwalithi yesithombe se-HDR?

Okokuqala udinga okokusebenza okufanele bese udinga ividiyo efanele. Idivayisi kufanele ihlangabezane nezimfuneko ezithile. Kufanele unakekele lezi zinto ezilandelayo:

• udinga i-TV eyi-8K noma i- 4K enamaphaneli okugreda kombala angu-10-bit;
• umehluko omkhulu – ophakeme ungcono;
• ukukhanya 1000 cd / m^2 (inani elilungile), kodwa ukuphakama kungcono.

I-Sony TV namanye amamodeli asekela i-HDR angase abe nezici ezengeziwe ezithinta ikhwalithi ye-movie noma igeyimu oyibukayo, njenge:

• Isixazululo se-4K Ultra HD – amaphikseli angu-3840 × 2160, ngenxa yokuthi ngisho nemininingwane emincane ibonakala;
• isixhumi se-HDMI 2.0 yisixazululo esihle uma ubuka amafilimu avela kweminye imithombo (ikhebula elikhethekile lisetshenziselwa ukuxhuma).

I-TV kufanele ihlangabezane nezimfuneko ezithile (bheka ilebula ye-UHD Premium) ukuze isithombe se-HDR singasindi kakhulu kumamukeli. Uma umsebenzisi efuna ukubuka amamuvi ku-inthanethi, kudingeka uxhumano lwesivinini esifinyelela okungenani ku-25 Mbps. Ukuxhumana kwe-inthanethi okungcono, kuba ngcono ikhwalithi yesithombe sokusakaza.
