Chii chinonzi HDR paTV, mamodheru anoitsigira uye maitiro ekugonesa tekinoroji

HDR (High Dynamic Range) paTV chinhu chaunosarudza chinoreva kunaka kwemifananidzo kana uchiona mafirimu. Tekinoroji yeHDR inoshandiswa mumaTV anhasi inoshandura kunaka kwemufananidzo waunoona. Mavara ari pachiratidziro anove akajeka, uye mufananidzo wacho pachawo – wakasarudzika. Iyo HDR ficha paTV inokutendera iwe kuti uratidze mifananidzo ine yakakosha tonal renji, kuti iwe ugone kunakidzwa neruzivo rweakasviba uye anopenya zvakanyanya.

Chii chinonzi HDR paTV, Mabhenefiti eHigh Dynamic Range

Iyo HDR modhi paTV inoita kuti mufananidzo uve wechokwadi, izvo zvinopa muoni chiitiko chinoshamisa pakuona mafirimu kana mapurogiramu aunofarira. Mavara akajeka anoita kuti kuona machisi uye zvimwe zviitiko zvemitambo zviwedzere kunakidza. Iyo HDR system paTV haina kufanana nguva dzose.

Zvakakosha kucherechedza kuti zviratidziro zvinoratidzwa pachiratidziri zvinoratidza izvo zvinoonekwa neziso remunhu. Mithunzi yakawanda yemuvara wega wega inowanikwa, iyo inoita kuti chifananidzo chive chakasikwa.

Iyo HD modhi paTV inonyanya kubatsira pakuona zvisikwa zvakarekodhwa uye mafirimu akapfurwa nemhando yepamusoro yekugadzira michina. Iwo mavara anoramba akafanana, saka grey, dema uye mamwe mavara akanyanya, akajeka uye akajeka kwazvo.

Ndeapi maTV anotsigira HDR

Kune akawanda HDR TV anowanikwa pamusika. Zvisinei, pakusarudza, iwe unofanirwa kuisa pfungwa pane zvakanyanya kukosha parameters kuitira kuti iwe unakidzwe nemhando yepamusoro yemufananidzo. HDR + Samsung Smart TV ndiyo musanganiswa wakakwana wekunyudza ruzivo kana uchiona mafirimu kana kutamba mitambo. Zvakare pamusika pane anotevera Smart TV modhi inotsigira yakawedzera simba renji:

1. Samsung TVs ichave yakakosha kutanga kune vese vashandisi vanoda mitambo nemafirimu anoshamisa. Hunhu hwakanaka hunoenderana nemutengo unonzwisisika, uye mhedzisiro yacho inotonyanya kuoneka nekuda kweFALD yakawanda-zone backlight.
2. Toshiba modhi maTV anokwanisika anowanzo tsigira HDR10 uye Dolby Vision. Nekuda kwemutengo wavo wakaderera, haugone kutarisira zvinokatyamadza kubva kwavari, sezvazvakaita nemamodheru anodhura, asi misiyano yeHDR mhando inoonekwa nekungotarisa.
3. Sony maTV anoenderana zvizere nePlayStation 5. Vanoshandisa multi-zone backlighting. Iwe unogona kusarudza kubva kumamodheru ane Dolby Visi, HDR 10 uye HDR 10+, nekuda kwekuti mhedzisiro panguva yekuona inogutsa kunyangwe vashandisi vanonyanya kuda.
4. Panasonic inopa 65-inch maTV anovimbisa emhando yepamusoro uye tarisiro yepamusoro yeHDR maficha. Mavara akajeka anokodzera kutariswa, saka bhaisikopo rega rega raunoona rinokupa iwe usingakanganwike chiitiko uye yakanakisa mhando yemifananidzo.

Inowanikwa HDR mafomati

HDR (High Dynamic Range) inoshandura se “high dynamic range”, iyo, kune rumwe rutivi, inoenderana nepfungwa yetekinoroji, asi kune rimwe divi, inoidzikisa zvakanyanya. Chinonyanya kukosha munyaya iyi ndeye tonal range yemufananidzo. HDR inokutendera kuti utarise mhando dzakasiyana dzemukati mumhando ine yakawedzera kupararira pakati peakareruka uye akasviba mapoinzi. Nekuda kweizvozvo, mavara ane simba, anotora mamwe echisikigo chimiro, uye ruzivo rwakapinza. Izvi zvinonyanya kucherechedzwa muzviitiko zvine rima mazviri asi zvine mavara akajeka. Sezvo paine akati wandei HDR tekinoroji zviyero pamusika, zvakakosha kuziva kuti anosiyana sei, ndedzipi sarudzo dzinodiwa nemidziyo yedu kuti tikwanise kuzvishandisa:

1. HDR10 ndiyo yekutanga HDR fomati uye inotsigirwa neTV yese kana vamwe vanogadzira skrini nevatepfenyuro (hapana rezinesi rinodiwa mune iyi kesi). Iyo HDR10 fomati inoshandisa gumi-bit color gamut (1024 mavara maringe ne220 pamaTV akajairika).
2. HDR10+ ifomati yakagadziridzwa maererano nemetadata inoshandiswa – ine simba. Iyo encoding yakavakirwa pagumi nembiri-bit color renji (4096 color values), ichipa kunyange nani mhedzisiro pane yekutanga HDR10. Musiyano uriwo mukuchengetedza data (muDolby Vhidhiyo fomati, furemu yega yega ifaira rakasiyana). Zvakakosha kuziva kuti kana teknolojia iyi yakatsigirwa, mutengo weTV unokwira.
3. Hybrid Log Gamma imhando yeHDR yakagadziriswa neBritish BBC (British Broadcasting Corporation) ichibatsirana neNHK, nhepfenyuro yenyika yeJapan.

Dambudziko nemaTV echinyakare nderekuti vazhinji vevaoni vavo vachiri kubatirira kune ekare SDR TV isingakwanise kuratidza iyo iri kuwedzera kuwanda HDR standard.

SDR zvakare yakachipa zvakanyanya kuita firimu, uye iyo BBC inozeza kusiya iyo inodhura-inoshanda fomati iyo makumi ezviuru zvevaoni vachiri kuvimba nayo. Iyo HLG fomati inokunda iyi “chipingaidzo” nekukodha zvese zviri zviviri HDR uye SDR ruzivo muchiratidzo chimwe chete, ichibvumira HDR-inoenderana maTV kuratidza mufananidzo wakakwidziridzwa. Hybrid Log Gamma inoshandisa inozivikanwa se “opto-optical transmission function”, inova maitiro anoshandiswa kushandura chiratidzo chekutepfenyura kuita chiedza chinoratidzwa paTV skrini yako.

Chii chaunoda kuti unakirwe HDR mufananidzo mhando?

Kutanga iwe unoda midziyo yakakodzera uye ipapo iwe unoda iyo chaiyo footage. Chigadzirwa chacho chinofanira kusangana nezvimwe zvinodiwa. Iwe unofanirwa kutarisira zvinotevera zvinhu:

• unoda 8K kana 4K TV ine 10-bit color gradation panels;
• kusiyanisa kwepamusoro – iyo yakakwirira iri nani;
• kupenya 1000 cd / m^2 (yakanyanya kukosha), asi iyo yakakwirira iri nani.

Sony TV uye mamwe mamodheru anotsigira HDR anogona kunge aine zvimwe zvinokanganisa kunaka kwemufirimu kana mutambo wauri kuona, senge:

• 4K Ultra HD resolution – 3840 × 2160 pixels, nekuda kwekuti kunyange zvidiki zvidiki zvinoonekwa;
• iyo HDMI 2.0 connector ndiyo mhinduro yakanaka kana uchiona mafirimu kubva kune dzimwe nzvimbo (tambo yakakosha inoshandiswa pakubatanidza).

Iyo TV inofanirwa kusangana nezvimwe zvinodiwa (tsvaga iyo UHD Premium label) kuitira kuti mufananidzo weHDR usanyanya kurema kune anogamuchira. Kana mushandisi achida kuona mabhaisikopo kubva paInternet, chinongedzo chekumhanya chinodiwa chinosvika kanenge 25 Mbps. Izvo zvirinani kubatana kweInternet, zvirinani kunaka kwemufananidzo wekutepfenyura.
