Izinguquko zemininingwane kusukela kukhebula le-HDMI 1.0 kuya ku-2.1

Inguqulo yokuqala ye-HDMI, inguqulo 1.0, yethulwa ngoDisemba 2002. Kungashiwo ukuthi yenzelwe ngokukhethekile isofthiwe ye-HD egcwele njenge-Blu-ray yalowo nyaka. Isici sayo esikhulu ukuthi ihlanganisa ukudluliswa kwesithombe nomsindo ngesikhathi esisodwa. Uma kuqhathaniswa nekhebula le-DVI kanye Ikhebula le-Displayport kumakhompyutha, Isixhumi esibonakalayo sokudlulisa isithombe esimsulwa, esifaneleka kakhulu imishini yomsindo nevidiyo. I-HDMI 1.0 isivele isekela ividiyo ye-DVD ne-Blu-ray, ene-bandwidth ephezulu engu-4.95 Gbps, lapho i-3.96 Gbps isetshenziselwa ukudlulisa ukusakazwa kwevidiyo, okungasekela i-1080/60p noma i-UXGA resolution; ukwesekwa komsindo i-LPCM 24bit/192kHz yeziteshi ezingu-8, ngamanye amazwi, isakazwe ku-Hi-Res yeziteshi eziningi. Uma kuqhathaniswa nezincazelo zekhebula zesikhathi esifanayo, inamandla impela; manje isithuthukisiwe yaba yinguqulo ye-HDMI2.1; izinguquko ezinguqulweni zakamuva zitholakala kakhulu Ngokuphathelene namapharamitha okuklama, isakhiwo sentambo asikashintshi kakhulu!

Ekuqaleni konyaka, inhlangano yokuphatha ejwayelekile ye-HDMI i-HMDI LA ikhiphe i- I-Hdmi 2.1incazelo ejwayelekile (i-HDMI standard ibuyekeziwe futhi, futhi inguqulo ithuthukiswe yaba yi-HDMI 2.1a). Imininingwane ejwayelekile entsha ye-HDMI 2.1a izongeza isici esisha esibizwa ngokuthi i-SBTM (Source-Based Tone Mapping) Umsebenzi uvumela amafasitela ahlukene ukuthi abonise okuqukethwe kwe-SDR ne-HDR ngesikhathi esisodwa ukuze kuthuthukiswe umphumela wokubonisa we-HDR futhi kunikeze abasebenzisi ulwazi olungcono. Ngesikhathi esifanayo, amadivayisi amaningi akhona angasekela umsebenzi we-SBTM ngezibuyekezo ze-firmware. Muva nje, i-HMDI LA imemezele ngokusemthethweni ukuthi iphinde yathuthukisa indinganiso ye-HDMI 2.1a futhi yethula umsebenzi owusizo kakhulu. Esikhathini esizayo, izintambo ezintsha zizosekela ubuchwepheshe be-"HDMI Cable Power" ukuthola amakhono okunikeza ugesi. Kungaqinisa ukunikezwa kwamandla kwemishini yomthombo futhi kuthuthukise ukuzinza kokudluliselwa kwebanga elide. Kalula nje, kungaqondwa ukuthi ngokusekelwe kubuchwepheshe be-"HDMI Cable Power", ikhebula ledatha le-HDMI elisebenzayo lingathola amandla amakhulu okunikeza ugesi kusuka kudivayisi yomthombo. Ngisho nekhebula ledatha le-HDMI elinobude obungamamitha amaningana alidingi amandla engeziwe. Ukunikezwa kwamandla kulula kakhulu.
