Ukubuka konke Kwezobuchwepheshe kwe-HDMI 2.1b Ukucaciswa

Kubathandi bomsindo nevidiyo, okokusebenza okujwayeleke kakhulu ngokungangabazeki izintambo ze-HDMI nezixhumi ezibonakalayo. Selokhu kwakhululwa inguqulo engu-1.0 yokucaciswa kwe-HDMI ngo-2002, sekuyiminyaka engaphezu kwengu-20. Eminyakeni engu-20-plus edlule, i-HDMI isibe indinganiso yesixhumi esibonakalayo esetshenziswa kakhulu kumadivayisi alalelwayo namavidiyo. Ngokusho kwamarekhodi asemthethweni, umthamo wokuthunyelwa we-HDMI ufinyelele amayunithi ayizigidi eziyizinkulungwane ezingu-11, okulingana cishe namadivayisi amabili we-HDMI ngomuntu ngamunye emhlabeni jikelele. Inzuzo enkulu ye-HDMI ukufana kwezinga layo. Eminyakeni engu-20 edlule, usayizi womzimba wesixhumi esibonakalayo esijwayelekile se-HDMI uhlale ungashintshile, futhi iphrothokholi yesofthiwe izuze ukuhambisana okuphelele emuva. Lokhu kulungele ikakhulukazi izinto zikagesi ezinkulu zasendlini ezinokuvuselelwa kwehadiwe okuhamba kancane, ikakhulukazi amathelevishini. Ngisho noma i-TV yasekhaya iyimodeli endala kusukela eminyakeni engaphezu kweshumi edlule, ingaxhunywa ngokuqondile kumakhonsoli egeyimu wesizukulwane esilandelayo ngaphandle kwesidingo sama-adaptha. Ngakho-ke, eminyakeni yamuva nje, i-HDMI ishintshe ngokushesha ividiyo yengxenye edlule, i-AV, umsindo, nezinye izixhumanisi kumathelevishini futhi isibe isikhombimsebenzisi esivame kakhulu kumathelevishini. Ngokwezibalo, yonke imikhiqizo kamabonakude emakethe ngo-2024 isebenzisa ubuchwepheshe be-HDMI, futhi i-HDMI isiphinde yaba inkampani ehamba phambili yamafomethi anencazelo ephezulu njenge-4K, 8K, ne-HDR. Izinga le-HDMI 2.1a selithuthukisiwe futhi: lizongeza amandla okunikezwa kwamandla ezintamboni futhi lidinga ukufakwa kwama-chip kumadivayisi omthombo.

I-HDMI® Specification 2.1b inguqulo yakamuva ye-HDMI® Specification, esekela ububanzi bokulungiswa kwamavidiyo aphezulu namazinga okuvuselela, okuhlanganisa i-8K60 ne-4K120, kanye nezinqumo ezifika ku-10K. Iphinde isekele amafomethi we-HDR ashukumisayo, amandla omkhawulokudonsa akhuphuka abe ngu-48Gbps HDMI. Izintambo ezintsha ze-Ultra High Speed ​​HDMI zisekela umkhawulokudonsa ongu-48Gbps. Lawa makhebuli aqinisekisa ukuhlinzekwa kwezici ezizimele zomkhawulokudonsa ophezulu kakhulu, okuhlanganisa ividiyo engacindezelwanga ye-8K enokusekelwa kwe-HDR. Ane-ultra-low EMI (ukuphazamiseka kazibuthe), okunciphisa ukuphazamiseka kumadivayisi aseduze angenawaya. Izintambo zibuyela emuva ziyahambisana futhi zingasetshenziswa namadivayisi akhona e-HDMI.

Izici ze-HDMI 2.1b zifaka:

Ukulungiswa okuphezulu kwevidiyo: Ingakwazi ukusekela uhla lwezinqumo eziphakeme namazinga okuvuselela ngokushesha (okuhlanganisa i-8K60Hz kanye ne-4K120Hz), inikeze umuzwa wokubuka ogxile kanye nemininingwane eshelelayo yokunyakaza okusheshayo. Isekela isinqumo esingafika ku-10K, ihlangabezana nezidingo ze-AV yokuhweba, izinhlelo zokusebenza zezimboni, nezomsebenzi.
I-Dynamic HDR iqinisekisa ukuthi isigcawu ngasinye ngisho nohlaka lwevidiyo lubonisa amanani afanelekile okujula, imininingwane, ukukhanya, ukugqama, kanye ne-gamut yombala ebanzi.
Imephu yethoni esekelwe emthonjeni (SBTM) isici esisha se-HDR. Ngaphandle kwemephu ye-HDR eqedwe idivayisi yokubonisa, iphinde inike amandla idivayisi yomthombo ukuthi yenze ingxenye yemephu ye-HDR. I-SBTM iwusizo ikakhulukazi lapho ihlanganisa amavidiyo e-HDR ne-SDR noma izithombe zibe isithombe esisodwa, njengesithombe-esithombeni noma imihlahlandlela yohlelo enamawindi evidiyo ahlanganisiwe. I-SBTM iphinde ivumele i-PC namadivayisi amageyimu ukuthi akhiqize ngokuzenzakalela amasiginali e-HDR athuthukisiwe ukuze asebenzise ngokugcwele amakhono e-HDR esibonisi ngaphandle kwesidingo sokucushwa mathupha kwedivayisi engumthombo.

Izintambo ze-HDMI ezinesivinini esiphezulu zingasekela umsebenzi ongacindezelwanga we-HDMI 2.1b kanye nomkhawulokudonsa ongu-48G owusekelayo. I-EMI ekhishiwe ezintanjeni iphansi kakhulu. Futhi zibuyela emuva ziyahambisana nezinguqulo zangaphambili zezinga le-HDMI futhi zingasetshenziswa namadivayisi akhona e-HDMI.
Ukucaciswa kwe-HDMI 2.1b kuthatha indawo ye-2.0b, kuyilapho ukucaciswa kwe-2.1a kuqhubeka nokubhekisela futhi kuncike ekucacisweni kwe-HDMI 1.4b. I-HDMI®
Indlela yokuhlonza yemikhiqizo ye-HDMI 2.1b
Ukucaciswa kwe-HDMI 2.1b kufaka phakathi ikhebuli entsha - I-Ultra High-Speed ​​HDMI® Cable. Iyona kuphela ikhebula ethobelana nezicaciso eziqinile, okuhloswe ngayo ukuqinisekisa ukusekelwa kwayo yonke imisebenzi ye-HDMI 2.1b, okuhlanganisa i-8k@60 engacindezelwanga kanye ne-4K@120. Umthamo womkhawulokudonsa othuthukisiwe wale khebula usekela kufika ku-48Gbps. Wonke amakhebuli aqinisekisiwe anoma yibuphi ubude kufanele aphumelele ukuhlolwa kwesitifiketi se-HDMI Forum Authorized Testing Center (Iforamu ATC). Uma isiqinisekisiwe, ikhebuli izodinga ukuthi ilebula yesitifiketi se-Ultra High-Speed ​​HDMI inamathiselwe kuphakheji ngayinye noma iyunithi yokuthengisa, ukuze abathengi bakwazi ukuqinisekisa isimo sesitifiketi somkhiqizo.
