Kumayambiriro kwa chaka chino, bungwe loyang'anira HDMI standard HMDI LA linatulutsa HDMI 2.1a standard specification. HDMI 2.1a yatsopano idzawonjezera chinthu chotchedwa SOURce-based Tone Mapping (SBTM) kuti zilole kuti zinthu za SDR ndi HDR ziwonetsedwe mu Windows zosiyanasiyana nthawi imodzi kuti ziwongolere zotsatira za HDR kuti ogwiritsa ntchito azisangalala nazo. Nthawi yomweyo, zipangizo zambiri zomwe zilipo zitha kuthandizira ntchito ya SBTM kudzera mu firmware update. Tsopano HMDI LA yalengeza mwalamulo kuti ikukweza muyezo wa HDMI 2.1A kuti ipange mawonekedwe othandiza kwambiri. M'tsogolomu, Cable yatsopanoyi idzathandizira ukadaulo wa "HDMI Cable Power" kuti ipeze mphamvu yamagetsi. Ikhoza kulimbitsa mphamvu yamagetsi ya zida zoyambira ndikukweza kukhazikika kwa kutumiza kwakutali. Mfundo yosavuta, yomwe ingamveke ngati kutengera ukadaulo wa "HDMI Cable Power", mzere wamagetsi wa HDMI wogwira ntchito ukhoza kupeza mphamvu yayikulu yamagetsi kuchokera ku zida zoyambira, ngakhale utakhala wautali mamita ochepa, wosafunikiranso mphamvu yowonjezera, umakhala wosavuta.
"Tikudziwa kuti chingwe chikakhala chachitali, zimakhala zovuta kwambiri kutsimikizira kukhazikika kwa chizindikiro, ndipo liwiro lotumizira deta la HDMI 2.1 la 48 Gbps limapangitsa vutoli kukhala lodziwikiratu." Kuwonjezeredwa kwa ukadaulo wa HDMI Cable Power sikuti kumangothandiza mphamvu yamagetsi ya mizere ya data ya HDMI, komanso kumathandizira kukhazikika kwa kutumiza deta kutali, bola ngati chipangizo choyambira ndi chipangizo cholandira zithandizira ntchitoyi. Kuphatikiza apo, chingwe chatsopanocho chingalumikizidwe mbali imodzi yokha, mbali imodzi idzalembedwa pa chipangizo choyambira, ndipo mbali inayo iyenera kukhala ya chipangizo cholandira. Ngati kulumikizana kuli kolakwika, chipangizocho sichidzawonongeka, koma sichidzalumikizidwa. Zingwe za data za HDMI zokhala ndi ukadaulo wa "HDMI Cable Power" zimaphatikizapo cholumikizira cha Power chosiyana cha zida zoyambira zomwe sizikugwirizana ndi ukadaulo, nthawi zambiri zolumikizira izi ndi madoko a USB Micro kapena USB Type-C. Popeza zida zoyambira zambiri zimawonjezera chithandizo cha ukadaulo wa "HDMI Cable Power", zomwe zimapangitsa kuti ogwiritsa ntchito apange malo ochitira masewera olimbitsa thupi osavuta komanso odalirika.
Chipu ya HDMI
Mukagwiritsa ntchito zida ndi zingwe zothandizira Cable Power, mbali imodzi yokha ya Cable ingalumikizidwe mu chipangizo choyambira, chomwe ndi kumapeto komwe kumagwiritsidwa ntchito kulandira Mphamvu yowonjezera. Koma ngakhale mutachitembenuza mozondoka, palibe vuto pa chipangizocho, koma chingwecho sichitumiza chizindikiro chilichonse. Kupeza malekezero a zingwe molondola kudzakhala kofunikira kwa iwo omwe akuganiza zozigwiritsa ntchito mkati mwa makoma kapena malo ena otsekedwa. Ngati mugula chipangizo chatsopano chomwe chimathandizira Cable Power, simuyenera kugwiritsa ntchito Cable Power yomwe imathandizira Cable Power nthawi zonse, doko latsopanoli limagwirizana ndi kubwerera m'mbuyo, ndipo zingwe zanu za HDMI zomwe zilipo zitha kuchita zomwe nthawi zonse zimachita. Mosiyana ndi zimenezi, ngati mwasankha kugula Cable yomwe imathandizira Cable Power, koma mulibe zida zilizonse za Cable Power, izi zili bwino. Zingwe zomwe zimathandizira Cable Power zimabwera ndi zolumikizira zosiyana za Power, kotero zimatha kuyendetsedwa ndi 5-volt USB adapter (nthawi zambiri micro-USB kapena USB Type-C) kuti zigwire ntchito, koma mukamaliza kukweza zida zanu zoyambira chizindikiro kuti zithandizire Cable Power, zidzatha kuchotsa adaputala yamagetsi ya USB, kukhazikitsa kumakhala kosavuta kwambiri. Ngati izi zikumveka ngati ukadaulo wa RedMere, mawaya ena a HDMI amagwiritsidwa ntchito kuti apeze mphamvu yowonjezera pang'ono kuchokera ku chipangizo choyambira kuti alole kuyenda mtunda wautali - chifukwa ndi lingaliro lofanana kwambiri. Kusiyana kwake ndikuti chingwe cha RedMere sichingasonkhanitse mphamvu zokwanira kuti chilole kukulitsa bandwidth yonse ya chingwe chothamanga kwambiri. Monga lingaliro la Cable Power, koma mukufuna kugula china chatsopano popanda kugwiritsa ntchito ndalama? Tsoka ilo sizingatheke, wolankhulira wa HDMI Licensing Authority adatero, chifukwa Cable Power ingafunike kuyika ma chips muzipangizo zoyambira, zomwe ziyenera kupangidwira ntchitoyo, ndipo nkhani ya HDMI chip iyamba.
