Kusintha kwa mafotokozedwe kuchokera pa chingwe cha HDMI 1.0 kupita ku 2.1
Mtundu woyamba wa HDMI, mtundu 1.0, unayambitsidwa mu Disembala 2002. Tinganene kuti unapangidwira mapulogalamu athunthu a HD monga Blu-ray ya chaka chimenecho. Mbali yake yayikulu ndi yakuti imagwirizanitsa zithunzi ndi mawu nthawi imodzi. Poyerekeza ndi chingwe cha DVI ndi Chingwe cha Displayport pa makompyuta, mawonekedwe osavuta otumizira zithunzi, oyenera kwambiri zida zamawu ndi makanema. HDMI 1.0 imathandizira kale makanema a DVD ndi Blu-ray, okhala ndi bandwidth yayikulu ya 4.95 Gbps, pomwe 3.96 Gbps imagwiritsidwa ntchito kutumiza makanema, omwe amatha kuthandizira 1080/60p kapena UXGA resolution; chithandizo chamawu cha 8-channel LPCM 24bit/192kHz, mwa kuyankhula kwina, chawulutsidwa ku Hi-Res yamakanema ambiri. Poyerekeza ndi mafotokozedwe a chingwe cha nthawi yomweyi, ndi champhamvu kwambiri; tsopano yasinthidwa kukhala mtundu wa HDMI2.1; kusintha kwa mitundu ina kumakhala makamaka mu Ponena za magawo a kapangidwe, kapangidwe ka waya sikunasinthe kwambiri!
Kumayambiriro kwa chaka, bungwe loyang'anira ma HDMI standard HMDI LA linatulutsa Hdmi 2.1muyezo wokhazikika (muyezo wa HDMI wasinthidwanso, ndipo mtunduwo wasinthidwa kukhala HDMI 2.1a). muyezo watsopano wa HDMI 2.1a udzawonjezera chinthu chatsopano chotchedwa SBTM (Source-Based Tone Mapping) Ntchitoyi imalola mawindo osiyanasiyana kuwonetsa zomwe zili mu SDR ndi HDR nthawi imodzi kuti akonze bwino zotsatira za HDR ndikupatsa ogwiritsa ntchito chidziwitso chabwino. Nthawi yomweyo, zida zambiri zomwe zilipo zitha kuthandizira ntchito ya SBTM kudzera mu zosintha za firmware. Posachedwapa, HMDI LA yalengeza mwalamulo kuti yakweza muyezo wa HDMI 2.1a kachiwiri ndikuyambitsa ntchito yothandiza kwambiri. M'tsogolomu, zingwe zatsopano zidzathandizira ukadaulo wa "HDMI Cable Power" kuti zipeze mphamvu zamagetsi. Zitha kulimbitsa mphamvu zamagetsi a zida zoyambira ndikukweza kukhazikika kwa kutumiza kwakutali. Mwachidule, zitha kumveka kuti kutengera ukadaulo wa "HDMI Cable Power", chingwe chogwira ntchito cha HDMI chogwira ntchito chingapeze mphamvu yayikulu yopezera mphamvu kuchokera ku chipangizo choyambira. Ngakhale chingwe chogwira ntchito cha HDMI chokhala ndi kutalika kwa mamita angapo sichifuna mphamvu yowonjezera. Mphamvu yamagetsi ndi yosavuta.
