Izinga le-HDMI 2.1a selithuthukisiwe futhi: amandla okunikezwa kwamandla azokwengezwa kukhebula, futhi i-chip izofakwa kudivayisi engumthombo.

Ngasekuqaleni konyaka, i-HDMI inhlangano yokuphatha ejwayelekile i-HMDI LA ikhiphe i-HDMI 2.1a ukucaciswa okujwayelekile.Ukucaciswa okujwayelekile kwe-HDMI 2.1a kuzokwengeza isici esibizwa nge-SOURce-based Tone Mapping (SBTM) ukuvumela okuqukethwe kwe-SDR ne-HDR ukuthi kuboniswe kuma-Windows ahlukene ngesikhathi esisodwa ukuze kuthuthukiswe umphumela wokubonisa we-HDR ukuze uthole ulwazi olungcono lomsebenzisi.Ngesikhathi esifanayo, amadivaysi amaningi akhona angasekela umsebenzi we-SBTM ngokusebenzisa isibuyekezo se-firmware.Manje i-HMDI LA isimemezele ngokusemthethweni ukuthi ithuthukisa izinga le-HDMI 2.1A ukwethula isici esiwusizo kakhulu.Ngokuzayo, Ikhebuli entsha izosekela ubuchwepheshe be-“HDMI Cable Power” ukuze kutholwe amandla okunikezela Amandla.Ingaqinisa ukunikezwa kwamandla kwemishini yomthombo futhi ithuthukise ukuzinza kokudluliswa kwebanga elide.Iphuzu elilula, lingaqondwa njengelisekelwe kubuchwepheshe be-“HDMI Cable Power”, ulayini wedatha we-HDMI osebenzayo osebenzayo ungathola umthamo omkhulu Wokuhlinzeka Amandla kumshini womthombo, ngisho noma ungamamitha ambalwa ubude umugqa wedatha we-HDMI, awusadingi. Ukunikezwa kwamandla okungeziwe, kulula kakhulu.

“Siyazi ukuthi uma ikhebula ende, kuba nzima nakakhulu ukuqinisekisa ukuzinza kwesignali, kanye nesivinini sokudlulisa idatha se-HDMI 2.1 esingu-48 Gbps senza le nkinga ibe sobala kakhulu.”Ukwengezwa kobuchwepheshe be-HDMI Cable Power akunikezi amandla okunikezwa kwamandla kwemigqa yedatha ye-HDMI kuphela, kodwa futhi kuthuthukisa ukuzinza kokudluliswa kwedatha okude, inqobo nje uma kokubili idivayisi engumthombo nedivayisi eyamukelayo isekela lo msebenzi.Ngaphezu kwalokho, ikhebula elisha lingaxhunywa ohlangothini olulodwa kuphela, isiphetho esisodwa sizomakwa esisetshenziswa somthombo, kanti esinye isiphetho kufanele sibe ngesedivayisi eyamukelayo.Uma ukuxhumeka kungalungile, idivayisi ngeke yonakale, kodwa ngeke ixhumeke.Izintambo zedatha ye-HDMI ezinobuchwepheshe be-“HDMI Cable Power” zifaka phakathi isixhumi Samandla esihlukile samadivayisi omthombo angasekeli ubuchwepheshe, ngokuvamile lezi zixhumi ziyi-USB Micro noma izimbobo ze-USB Type-C.Njengoba amadivayisi omthombo anda engeza usekelo lobuchwepheshe be-“HDMI Cable Power”, okwenza kube lula kubasebenzisi ukwakha ithiyetha yasekhaya elula nethembekile.

I-HDMI chip

Uma usebenzisa okokusebenza namakhebuli asekela Amandla Ekhebula, indawo eyodwa kuphela Yekhebula engaxhunywa kudivayisi engumthombo, okuwukugcina okusetshenziselwa ukuthola Amandla engeziwe.Kodwa noma uyibhekise phansi, akukho monakalo kudivayisi, kodwa ikhebula alidlulisi noma iyiphi isignali nhlobo.Ukuthola amaphethelo ezintambo ngendlela efanele kuzobaluleka kulabo abacabanga ukuwasebenzisa ngaphakathi kwezindonga noma ezinye izikhala ezivaliwe.Uma uthenga idivayisi entsha esekela Amandla Ekhebula, akudingekile ukuba usebenzise Ikhebuli esekela Amandla Ekhebula ekusetshenzisweni okuvamile, imbobo entsha ihambisana nokubuyela emuva, futhi izintambo zakho ezikhona ze-HDMI zisengenza ezihlala zikwenza.Ngokuphambene, uma unquma ukuthenga Ikhebuli esekela Amandla Ekhebula, kodwa okwamanje awukabi ngumnikazi wanoma iyiphi impahla Yamandla Ekhebula, lokhu nakho kulungile.Amakhebuli asekela Amandla Ekhebula afika nezixhumi ezihlukene Zamandla, ukuze anikwe amandla nge-adaptha ye-USB engu-5-volt (imvamisa i-micro-USB noma i-USB Type-C) ukuze asebenze, kodwa uma ekugcineni uthuthukisa okokusebenza komthombo wakho wesiginali ukuze kusekele Ikhebuli. Amandla, Azokwazi ukuqeda i-adaptha yamandla ye-USB, ukufakwa kulula ngokwemvelo.Uma lokhu kuzwakala kufana nobuchwepheshe be-RedMere, ezinye izintambo ze-HDMI zisetshenziselwa ukuthola amandla engeziwe kancane kusuka kudivayisi yomthombo ukuvumela ukugijima amabanga amade - lokho kungenxa yokuthi umqondo ofanayo kakhulu.Umehluko ukuthi ikhebula le-RedMere alikwazi ukuqoqa amandla anele ukuvumela ukunwetshwa komkhawulokudonsa ogcwele wekhebula lejubane eliphezulu.Njengombono weCable Power, kodwa ufuna ukuthenga okuthile okusha ngaphandle kokusebenzisa imali?Ngeshwa lokho akunakwenzeka, umkhulumeli we-HDMI Licensing Authority uthe, ngoba i-Cable Power izodinga ukufaka ama-chips kumadivayisi omthombo, okuzodinga ukwenzelwa lowo msebenzi, futhi indaba ye-chip ye-HDMI izoqala.
