Ekuqaleni kwalonyaka, inhlangano yokuphatha ejwayelekile ye-HDMI i-HMDI LA ikhiphe imininingwane ejwayelekile ye-HDMI 2.1a. Imininingwane entsha ejwayelekile ye-HDMI 2.1a izongeza isici esibizwa ngokuthi i-SOURce-based Tone Mapping (SBTM) ukuvumela okuqukethwe kwe-SDR ne-HDR ukuthi kuboniswe kumaWindows ahlukene ngesikhathi esisodwa ukuze kuthuthukiswe umphumela wokubonisa we-HDR ukuze kube nolwazi olungcono lomsebenzisi. Ngesikhathi esifanayo, amadivayisi amaningi akhona angasekela umsebenzi we-SBTM ngokuvuselelwa kwe-firmware. Manje i-HMDI LA imemezele ngokusemthethweni ukuthi ithuthukisa indinganiso ye-HDMI 2.1A ukuze yethule isici esiwusizo kakhulu. Esikhathini esizayo, ikhebula elisha lizosekela ubuchwepheshe be-“HDMI Cable Power” ukuze lithole amandla okunikezwa kwamandla. Lingaqinisa ukunikezwa kwamandla kwemishini yomthombo futhi lithuthukise ukuzinza kokudluliselwa kwebanga elide. Iphuzu elilula, elingaqondwa njengoba ngokusekelwe kubuchwepheshe be-“HDMI Cable Power”, umugqa wedatha we-HDMI osebenzayo osebenzayo ungathola amandla amakhulu okunikezwa kwamandla kusuka kumishini yomthombo, noma ngabe umugqa wedatha we-HDMI ubude obungamamitha ambalwa, awusadingi ukunikezwa kwamandla okwengeziwe, uba lula kakhulu.
“Siyazi ukuthi uma ikhebula lide, kuba nzima kakhulu ukuqinisekisa ukuzinza kwesignali, kanye nesivinini sokudlulisa idatha esijwayelekile se-HDMI 2.1 esingu-48 Gbps kwenza le nkinga ibe sobala kakhulu.” Ukwengezwa kobuchwepheshe be-HDMI Cable Power akugcini nje ngokwenza amandla okunikezwa kwamandla emigqeni yedatha ye-HDMI, kodwa futhi kuthuthukisa ukuzinza kokudluliselwa kwedatha ebangeni elide, uma nje idivayisi yomthombo kanye nedivayisi eyamukelayo kusekela lo msebenzi. Ngaphezu kwalokho, ikhebula elisha lingaxhunywa ohlangothini olulodwa kuphela, ukuphela okukodwa kuzomakwa kudivayisi yomthombo, kanti okunye ukuphela kumele kube kwedivayisi eyamukelayo. Uma uxhumano lungalungile, idivayisi ngeke yonakale, kodwa ngeke ixhunywe. Izintambo zedatha ze-HDMI ezinobuchwepheshe be-“HDMI Cable Power” zifaka isixhumi samandla esihlukile samadivayisi omthombo angasekeli ubuchwepheshe, ngokuvamile lezi zixhumi ziyi-USB Micro noma i-USB Type-C ports. Njengoba amadivayisi omthombo amaningi engeza ukwesekwa kobuchwepheshe be-“HDMI Cable Power”, okwenza kube lula kubasebenzisi ukwakha i-home theater elula nethembekile.
I-chip ye-HDMI
Uma usebenzisa imishini namakhebula asekela i-Cable Power, kungaxhunywa ukuphela okukodwa kwe-Cable kudivayisi yomthombo, okuyi-end esetshenziselwa ukuthola amandla engeziwe. Kodwa noma ngabe uyiphendulela phansi, akukho monakalo kudivayisi, kodwa ikhebula alidluliseli nhlobo isignali. Ukuthola iziphetho zamakhebula ziqondiswe kahle kuzoba kubalulekile kulabo abacabanga ukuzisebenzisa ngaphakathi kwezindonga noma kwezinye izikhala ezivalekile. Uma uthenga idivayisi entsha esekela i-Cable Power, akudingeki usebenzise i-Cable esekela i-Cable Power ekusetshenzisweni okuvamile, i-port entsha iyahambisana nokubuyela emuva, futhi amakhebula akho e-HDMI akhona asengawenza lokho ahlala ekwenza. Ngokuphambene nalokho, uma unquma ukuthenga i-Cable esekela i-Cable Power, kodwa awunayo imishini ye-Cable Power okwamanje, lokhu kulungile. Amakhebula asekela i-Cable Power eza nezixhumi zamandla ezihlukene, ngakho-ke angasebenza nge-adaptha ye-USB engu-5-volt (ngokuvamile i-micro-USB noma i-USB Type-C) ukuze asebenze, kodwa uma ekugcineni uthuthukisa imishini yakho yomthombo wesignali ukuze isekele i-Cable Power, izokwazi ukuqeda i-adaptha yamandla e-USB, ukufakwa kulula kakhulu ngokwemvelo. Uma lokhu kuzwakala njengobuchwepheshe beRedMere, ezinye izintambo ze-HDMI zisetshenziselwa ukuthola amandla engeziwe kusuka kudivayisi yomthombo ukuze kuvunyelwe ukusebenza amabanga amade - lokho kungenxa yokuthi umqondo ofanayo kakhulu. Umehluko ukuthi ikhebula leRedMere alikwazi ukuqoqa amandla anele ukuvumela ukunwetshwa kwe-bandwidth ephelele yekhebula lesivinini esikhulu. Njengombono weCable Power, kodwa ufuna ukuthenga into entsha ngaphandle kokusebenzisa imali? Ngeshwa lokho akunakwenzeka, kusho okhulumela i-HDMI Licensing Authority, ngoba iCable Power kuzodingeka ifake ama-chip kumadivayisi omthombo, okuzodinga ukwenziwa ngqo kulowo msebenzi, futhi indaba ye-HDMI chip izoqala.
