U-Vratislav Holub Muva nje sibone kwethulwa uchungechunge olusha lwe-Apple TV 4K, oluziqhayise ngezinto eziningi ezintsha ezithokozisayo. Ngokukhethekile, ibone ukwanda okubalulekile ekusebenzeni noma ukususwa kwesixhumi se-Ethernet, manje esitholakala kuphela enguqulweni ebiza kakhulu enesitoreji esikhulu. Kodwa ake siqhubekele kwikhwalithi yesithombe. Njengoba igama ngokwalo liphakamisa, i-Apple TV iyakwazi ukuletha okuqukethwe kwe-multimedia kuze kufike ekulungisweni kwe-4K. Nokho, kusekude ukuphela ngaye. I-HDR idlala indima ebaluleke kakhulu.
Kungaba njalo okuthakaselayo
Adam Kos I-HDR noma i-High Dynamic Range (ububanzi obuguquguqukayo obuphezulu) ubuchwepheshe obusebenzisa ukujula okukhulu futhi obungakwazi ukunakekela isithombe sekhwalithi ephezulu kakhulu. Kafushane kakhulu, kungashiwo ukuthi uma ubuka okuqukethwe kwe-HDR, unenguqulo engcono kakhulu etholakalayo, lapho yonke imininingwane eyodwa ibonakala khona. Ngokucacile, imininingwane ingabonwa ngisho nasethunzini elimnyama kakhulu, noma ngokuphambene nalokho ezigcawini ezikhanya ngokukhazimulayo. Kodwa kulokhu, udinga ukuba nehadiwe ehambisanayo engakwazi ukubonisa kuphela kodwa futhi idlale i-HDR. Ngakho-ke umbandela wokuqala i-TV esekelwa amafomethi athile e-HDR. Ngakho-ke ake sigxile ekutheni yini ngempela i-Apple TV 4K esekelayo nokuthi yikuphi okuqukethwe (nokuthi kuphi) ongakubuka.
Imaphi amafomethi we-HDR i-Apple TV ewasekelayo?
Okokuqala, ake sibheke ukuthi yimaphi amafomethi we-HDR esekelwa yi-Apple TV. Uma sikhuluma ngesizukulwane sakamuva, bese sihlangabezana nezindinganiso ze-Dolby Vision kanye ne-HDR10+/HDR10/HLG ngefomethi ye-HEVC. Kuzo zombili izimo, zisebenza kuzinqumo ezifika ku-4K (2160p) kumafreyimu angama-60 ngomzuzwana. Kodwa-ke, uchungechunge oludala lwe-Apple TV 4K (isizukulwane sesibili) alwenzi kahle kangako. Ngokucacile, ayinikezi i-HDR2+, nokho ingakwazi ukuphatha i-Dolby Vision, i-HDR10 ne-HLG. Amafomethi angawodwana abalulekile ekudlaleni okuqukethwe ngokwako. Noma okuqukethwe kungase kusatshalaliswe nge-HDR, lokho akusho ukuthi uzokwazi ukukudlala. Ukhiye yilelo kanye izinga nokuthi idivayisi yakho iyalisekela nhlobo.
Isibonelo, uma ubunefilimu enobubanzi obuguquguqukayo obuphezulu (i-HDR) ngefomethi ye-HDR10+ futhi ubufuna ukuyidlala ku-TV esekela i-Dolby Vision kuphela, cishe ulahlekelwe yinhlanhla futhi ngeke uyijabulele. izinzuzo ezishiwo. Ngakho-ke kuyadingeka njalo ukuthi izindinganiso zihambisane. Ngakho masiyifingqe ngokushesha.
I-Apple TV 4K (2022) isekela amafomethi alandelayo:
- Umbono we-Dolby
- I-HDR10
- HDR10 +
- HLG
Yini engabukwa ku-HDR ku-Apple TV
Uma ufuna ukusebenzisa i-Apple TV 4K yakho ukuze udlale okuqukethwe kwe-HDR, kuya ngokuthi uyidlala kuphi. Uma uya kuhlelo lokusebenza lwe-TV lwendabuko, awudingi ukubhekana nanoma yini. Vele uthole imuvi emakwe ngesithonjana se-HDR futhi usuqedile. Uma i-HDR isekela okuqukethwe kwe-multimedia ethile kanye ne-TV yakho, i-Apple TV izoyidlala ngokuzenzekelayo ngendlela engcono kakhulu. Kodwa qaphela ngoxhumo lwenethiwekhi. Njengoba amamuvi ebizwa ngokuthi ukusakaza nge-inthanethi, athonywa kakhulu ukusebenza kwamanje koxhumano ngokwalo. Uma siwohloka, ikhwalithi yesithombe ingase yehle. I-Apple incoma ngokuqondile isivinini esincane sokulanda esingu-4Mbps sokusakaza ividiyo ye-25K, ngaphandle kwalokho ikhwalithi izokwehliswa ngokuzenzakalelayo ukuze idlalwe ukuze isebenze nhlobo.
Igalari yezithombe
Izinkundla zokusakaza
Kodwa kuthiwani uma ufuna ukubuka okuqukethwe kwe-HDR ngaphandle kohlelo lokusebenza lwendabuko? Iningi lezinhlelo zokusebenza/izinsizakalo azinankinga nalokhu. Ngokungangabazeki, inkundla yokusakaza ethandwa kakhulu yi-Netflix, okwamanje esekela amafomethi amabili we-HDR - i-Dolby Vision ne-HDR10 - okusho ukuthi ngisho nabanikazi besizukulwane esedlule i-Apple TV 4K bangajabulela amandla ayo aphelele. Ukuze ukwazi ukubuka izinhlelo zakho eziyintandokazi ku-Netflix nge-HDR, udinga ukukhokhela uhlelo olubiza kakhulu lwe-Premium (esekela ukulungiswa okufika ku-4K + HDR) kanye nedivayisi esekela amazinga e-Dolby Vision noma i-HDR (i-Apple TV 4K + ithelevishini). Akugcini lapho. Kufanele uxhume i-Apple TV 4K kumabonakude ngesixhumi se-HDMI esisekelwa i-HDCP 2.2. Ezimweni eziningi, lokhu kuyimbobo ye-HDMI 1. Ngemva kwalokho, ngenhlanhla kulula. Udinga nje ukuba noxhumano lwe-inthanethi oluzinzile (i-Netflix ithi isivinini sokulanda esingu-15 Mbps noma ngaphezulu) bese usetha ikhwalithi yokusakaza ibe "Phezulu" kuzilungiselelo ze-Netflix.
Empeleni, isebenza ngendlela efanayo nakwezinye izinkundla zokusakaza. Isibonelo, singabala i-HBO MAX. Isevisi ithi okudingayo nje i-TV elungile, idivayisi esekela ukudlalwa kwevidiyo efika ku-4K ku-HDR (Apple TV 4K), i-inthanethi eyanele (ubuncane obungu-25 Mbps, 50+ Mbps enconyiwe). Ngokufanayo, wonke amadivayisi kufanele axhunywe nge-HDMI 2.0 ne-HDCP 2.2. Zonke izihloko ezitholakala ku-4K ziyatholakala futhi ngokusekelwa kwe-HDR, esebenza ngokuzenzakalelayo (uma uhlangabezana nayo yonke imibandela).
Kungaba njalo okuthakaselayo
Ukundiza emhlabeni wonke nge-Apple 
noma iyiphi i-tv esekela uhlobo oluthile lwe-hdr isekela i-hdr10 eyisisekelo.
I-hdr10+ kanye nombono we-dolby kuyizengezo kuphela - ngakho-ke ku-TV enama-10 hhayi i-hdr10+, okuqukethwe kwe-hdr10+ kusazokhishwa ku-hdr (uma usebenzisa i-hdrXNUMX eyisisekelo)
Pho akazange ahlukane? Angazi okuningi ngakho
I-HDR izophinde ibe khona - okungukuthi, izosebenzisa ukukhanya okuphezulu kwephaneli nobubanzi obugcwele bemibala. ukwethulwa kwemibala kuphela okungaba "okungalungile"
kodwa umehluko ucishe ufane nomehluko wekhwalithi ye-mp3 phakathi kuka-192 no-256 kbs - abantu abaningi abawubhalisi ngisho
engcono kakhulu i-Dolby Vision, bese kuba i-HDR10+. Ama-TV amaningi anokunye noma okunye, okuqukethwe okuningi ku-Dolby Vision ngaphandle kwe-Amazon, kodwa kufike ne-Dolby Vision, futhi bheka Izindandatho Zamandla. Uma ufuna ikhwalithi ephezulu, kuzomele uthenge i-OLED kwaPanasonic, inakho kokubili kanye nezethulo ezinembe kakhulu ze-HDR emakethe.
Abantu abaningi abafana ne-OLED yakwa-LG, lapho baya khona nge-Dolby Vision, i-HDR10+ iyisizinda se-Samsung.
Sawubona, kuthiwani uma ngine-OLED LG TV futhi nginezinhlelo zokusebenza zokusakaza-bukhoma ezilayishwe kuyo ngokuqondile? Ingabe izodlalwa ngekhwalithi yesithombe efanayo nebhokisi le-apple tv? Siyabonga ngolwazi
uma unohlelo lwe-primo ku-TV yakho, aluhlangene nebhokisi
Okubalulekile: Setha i-Apple TV ku-4K SDR, futhi kuye ngokuqukethwe, kokubili yebo, khona-ke isithombe njengoba senziwa sizohlala sikufanela.
U-Pavel cishe wayezibuza ukuthi ngabe kukhona umehluko ngekhwalithi lapho, isibonelo, eqala i-Netflix ngokuqondile kuhlelo lokusebenza ku-TV, noma uma eqala i-Netflix nge-Apple TV.
