Niki HDR kuri TV, moderi irabishyigikira nuburyo bwo gukora ikoranabuhanga

HDR (High Dynamic Range) kuri TV ni ibintu bidahitamo bisobanura ubuziranenge bwamashusho mugihe ureba firime. Ikoranabuhanga rya HDR rikoreshwa muri TV zubu rihindura ubwiza bwishusho ureba. Amabara kuri ecran arasobanuka neza, kandi ishusho ubwayo – karemano. Ikiranga HDR kuri TV kigufasha kwerekana amashusho afite intera ihambaye ya tone, bityo urashobora kwishimira ibisobanuro birambuye byijimye kandi byiza cyane.

Niki HDR kuri TV, Inyungu zo murwego rwohejuru

Uburyo bwa HDR kuri TV butuma ishusho iba impamo, iha abayireba uburambe buhebuje iyo ureba firime cyangwa gahunda ukunda. Amabara meza atuma kureba imikino nibindi bikorwa bya siporo birushaho gushimisha. Sisitemu ya HDR kuri TV ntabwo buri gihe ari imwe. Moderi iboneka kumasoko iratandukanye mubwiza bwibishusho (HDR 10, HDR 10+, HLG na Dolby Vision irahari). Ibyiza bya hdr inkunga muri TV:

1. Ihitamo ritanga amabara meza kandi atandukanye cyane.
2. 4K TV ihujwe na HDR ituma abayikoresha bishimira kugenda neza n’amashusho afatika.

Birakwiye ko tumenya ko amashusho yerekanwe kuri ecran yerekana ibyo ijisho ryumuntu ribona. Igicucu kinini cya buri bara kirahari, bigatuma ishusho iba karemano.

Ubwoko bwa HD kuri TV ni ingirakamaro cyane cyane mu kureba amashusho y’ibidukikije na firime zafashwe hamwe n’ibikoresho byo mu rwego rwo hejuru. Indabyo ziguma ari zimwe, bityo imvi, umukara nandi mabara arakomeye, yaka kandi arasobanutse neza.

Nihe TV zishyigikira HDR

Hano hari TV nyinshi za HDR ziboneka kumasoko. Ariko, mugihe uhisemo, ugomba kwibanda kubintu byingenzi kugirango ubashe kwishimira ubwiza bwibishusho. HDR + Samsung Smart TV ni ihuriro ryiza kuburambe bwa immersive mugihe ureba firime cyangwa ukina imikino. No ku isoko hari Moderi ya Smart TV ikurikira ishyigikira intera yagutse:

1. TV za Samsung zizagira akamaro mbere yambere kubakoresha bakunda imikino na firime zidasanzwe. Ubwiza buhebuje bujyana nigiciro cyumvikana, kandi ingaruka ziragaragara cyane kuberako urumuri rwinshi rwa FALD.
2. Moderi ya Toshiba ni TV zihenze zikunze gushyigikira HDR10 na Dolby Vision. Bitewe nigiciro cyabyo gito, ntushobora kwitega ingaruka zitangaje kuri bo, nkuko bimeze kuri moderi zihenze cyane, ariko itandukaniro ryubwiza bwa HDR rigaragara iyo urebye.
3. Sony TV zirahuza rwose na PlayStation 5. Bakoresha amatara menshi ya zone. Urashobora guhitamo mubyitegererezo hamwe na Dolby Visi, HDR 10 na HDR 10+, kuberako ingaruka mugihe cyo kureba zizahaza nabakoresha cyane.
4. Panasonic itanga TV-65-yerekana ubwiza buhebuje kandi buteganijwe cyane kubiranga HDR. Amabara meza akwiye kwitabwaho, buri firime rero ureba iguha uburambe butazibagirana hamwe nubwiza bwamashusho.

Inkunga ya TV kuri HDR

Imiterere ya HDR iboneka

HDR (High Dynamic Range) isobanurwa ngo “urwego rwo hejuru rufite imbaraga”, kuruhande rumwe, ruhuye nigitekerezo cyikoranabuhanga, ariko kurundi ruhande, rugabanya cyane. Icyingenzi muriki gice ni tone yerekana ishusho. HDR igufasha kureba ubwoko butandukanye bwibirimo mubwiza bufite ubwiyongere bukwirakwira hagati yumucyo kandi wijimye. Nkigisubizo, amabara afite imbaraga, fata imiterere karemano, kandi ibisobanuro birakaze. Ibi biragaragara cyane cyane mubice byijimye ubwabyo ariko bifite ibibara byiza. Kubera ko ku isoko hari amahame menshi ya tekinoroji ya HDR ku isoko, ni ngombwa kumenya uko atandukanye, ni ubuhe buryo ibikoresho byacu bikenera kugirango tubashe kubikoresha:

1. HDR10 nuburyo bwibanze bwa HDR kandi bushigikirwa na TV zose cyangwa izindi nganda zikora ecran hamwe na tereviziyo (nta ruhushya rusabwa muriki kibazo). Imiterere ya HDR10 ikoresha gamut ya biti 10 (amabara 1024 na 220 kuri TV zisanzwe).
2. HDR10 + nuburyo bunoze muburyo bwa metadata yakoreshejwe – ni dinamike. Kodegisi ishingiye kumurongo wa 12-bit (ibara ryamabara 4096), itanga ibisubizo byiza kurenza HDR10. Itandukaniro riri no kubika amakuru (muburyo bwa Video ya Dolby, buri kadamu ni dosiye itandukanye). Ni ngombwa kumenya ko niba iri koranabuhanga rishyigikiwe, igiciro cya TV kizamuka.
3. Hybrid Log Gamma nuburyo bwa HDR bwakozwe na BBC yo mu Bwongereza (British Broadcasting Corporation) ku bufatanye na NHK, umunyamakuru w’igihugu cy’Ubuyapani.

Ikibazo na TV gakondo nuko benshi mubabareba bagifata kuri TV za kera za SDR zidashobora kwerekana ibipimo bisanzwe bya HDR.

SDR nayo ihendutse cyane gufata amashusho, kandi BBC isanzwe idashaka kureka imiterere ihendutse ibihumbi icumi byabareba baracyashingiraho. Imiterere ya HLG yatsinze iyi “mbogamizi” ikoresheje amakuru ya HDR na SDR mu kimenyetso kimwe, bigatuma televiziyo ihuza HDR yerekana ishusho nziza. Hybrid Log Gamma ikoresha ikizwi nka “imikorere ya opto-optique yohereza”, ni inzira ikoreshwa muguhindura ibimenyetso byamamaza mumucyo bigaragara kuri ecran ya TV yawe.

Niki ukeneye kwishimira ubwiza bwibishusho bya HDR?

Ubanza ukeneye ibikoresho byiza hanyuma ukenera amashusho meza. Igikoresho kigomba kuba cyujuje ibisabwa. Ugomba kwita ku bintu bikurikira:

• ukeneye TV 8K cyangwa 4K hamwe na 10-biti yo gutondekanya ibara;
• itandukaniro rinini – urwego rwo hejuru ni rwiza;
• umucyo 1000 cd / m ^ 2 (agaciro keza), ariko hejuru nibyiza.

Sony TV nizindi moderi zishyigikira HDR zishobora kuba zifite ibintu byinyongera nabyo bigira ingaruka kumiterere ya firime cyangwa umukino ureba, nka:

• 4K Ultra HD ikemurwa – 3840 × 2160 pigiseli, tubikesha utuntu duto duto tugaragara;
• umuhuza wa HDMI 2.0 nigisubizo cyiza mugihe ureba firime ziva ahandi (umugozi udasanzwe ukoreshwa muguhuza).

Televiziyo igomba kuba yujuje ibisabwa (reba ikirango cya UHD Premium) kugirango ishusho ya HDR itaremereye cyane kubakira. Niba umukoresha ashaka kureba firime kuri enterineti, birasabwa guhuza byihuse byihuta byibura 25 Mbps. Nibyiza guhuza umurongo wa enterineti, nibyiza byifoto yerekana.

Niki HDR kuri TV nimpamvu ikenewe, ni izihe nyungu itanga:

Nakura he ibikubiye mubwiza bwa HDR?

Sisitemu ya HDR muri TV ni ikintu cyiza cyane gituma abakoresha benshi bagura moderi runaka kubera inyungu zaganiriweho. Bituma kureba firime bishimishije rwose, amashusho arasobanuka neza, amabara arasobanutse neza, kandi itandukaniro rigaragara bigira ingaruka kumyumvire yishusho. Ariko, iyo umaze kugura ibyuma byawe, ni ngombwa kumenya aho watangirira gushakisha amashusho agufasha gupima ubushobozi bwibikoresho byawe. Amahitamo menshi aboneka aho ushobora gukuramo cyangwa kureba amashusho na firime muburyo bwa hdr:

1. 4K UHD Disiki ya Blu-ray . Umukinnyi winyongera arakenewe, buri gishya kigura amafaranga 3000.
2. Niba ushaka firime nziza kandi ukaba udashaka kwishyura cyane, hari ikindi gisubizo. Nibijyanye no gukoresha serivise. Icyamamare cyane mubakoresha ni Netflix (https://www.netflix.com/ru/), igufasha kureba firime na televiziyo muri HDR10 na Dolby Vision nziza.
3. Mubyongeyeho, ibiri muri HDR byakirwa kurubuga ruzwi rwa YouTube .

HDR – birakwiye amafaranga?

Niba utekereza kugura TV, birakwiye ko ureba moderi ifite amahitamo ya HDR kuko itanga uburambe bwinyongera kubantu bareba firime nizindi gahunda ziboneka mbere. Gukina neza no kureba ubuziranenge bizahaza abantu bose bafite ibyifuzo byinshi nibipimo byibikoresho bya elegitoronike bitanga imyidagaduro murugo. Ingaruka ya HDR kuri TV itanga inyungu nyinshi kubakoresha, icyakora iraboneka mubipimo byinshi. Kubwibyo, birakwiye kumenya ibiranga, hanyuma ugahitamo. HDR ni umusingi ukina kuri ecran zose.
