Intshayelelo
Ngokunyuka kwekhontrakthi ephakamileyo yevidiyo kunye nokwamukelwa kwe-HDTV, imfuno yesikhonkco esivumeleneyo esifanelekileyo yayimfuneko. I-interface ye-DVI yayisungulwe ngokutsha kwiinkqubo zekhomputha kwaye yafakwa kwiiyunithi ze-HDTV zakudala, kodwa kukho inani lokunciphisa naloo nto abakhiqizi bajonge ukuhlanganisa isixhobo esitsha. Ukususela kule ndawo, i-High-Definition Multimedia Interconnect okanye i-HDMI imigangatho yaphuhliswa eyayiyi-connecto video connector.
Abaxhamli abancinane abaQinisekisiweyo
Enye yeenzuzo ezinkulu ze-HDMI kwi-interface ye-DVI ubukhulu bomnxibelelwano. I-interface ye-DVI ifana nesayizi kwi-VGA interface ekhulayo kwi-1.5 intshi ngobubanzi. Umxhasi we- HDMI osemgangathweni ubuncinane kwisithathu kwisayizi soxhumano lwe-DVI. I-HDMI version 1.3 inkcazelo eyongeziweyo yenkxaso yenkampani encinci ye-HDMI eyayixhamla kwiiptops ezincinci kakhulu kunye ne-electronics zabathengi ezincinane ezifana neekhamera. Nge-HDMI ingu-1.4, umxhasi we-HDMI wongezwa kunye nekhonkco encinci eyayiluncedo ekusebenziseni ukusetyenziswa kwezixhobo zeethebhulethi kunye ne-smartphone.
Umsindo kunye neVidiyo kwiCandelo elilodwa
Izinzuzo zekhebula ze-HDMI ziba zivakaliswe ngakumbi kwi-DVI kuba i-HDMI nayo inomsindo wedijithali. Uninzi lweekhomputha zekhaya usebenzisa ubuncinane kunye kunye nangoko kunokwenzeka ukuya kwiintambo ezintathu zokubeka i-audio ukuya kuyo izithethi, ikhebula le-HDMI lenza lula ukuba inani leetambo lifune ukuqhuba isignali yomsindo kwisilathisi. Kwimigaqo yokuqala ye-HDMI yamakhadi emifanekiso, ukusetyenziswa kwee-nonsthrough kusetshenziselwa ukuongeza umrhumo womsindo kumakhadi anemifanekiso kodwa ezininzi ngoku sele ziqhuba ukuqhutshwa kwemisindo yokusingatha zombini izandi kunye nevidiyo ngexesha elifanayo.
Ngoxa i-audio kunye nevidiyo kwikhebuli enye yayingqalileyo xa i-HDMI iqalelwa kuqala, le nxalenye iphinde ifakwe kwikhonkco yevidiyo ye- DisplayPort . Ekubeni oko kwenzekile, iqela le-HDMI liye lasebenza ekukhuliseni inkxaso yongezwa ngee-multi-channel. Oku kubandakanya 7.1 isandi kwi-HDMI inguqulelo 1.4 kwaye ngoku ukuya kwii-32 zezandi zomsindo nge-HDMI version 2.0.
Ukunyuka koMbala
Umbala we-Analog kunye nedijithali yeekhompyutheni ze-PC sele inqandekile kumbala we-24-bit ovelisa imibala eyi-16.7 yezigidi. Oku ngokuqhelekileyo kuthathwa njengombala oyinyaniso kuba iso lomntu alikwazi ukuhlukanisa phakathi kwee-shades kalula. Ngenxa yesisombululo sokwandiswa kwe-HDTV , iliso lomntu linokuchazela umahluko kumgangatho ophezulu wombala phakathi kobunzulu bombala obu-24-bit kunye namanqanaba aphezulu, nokuba ngaba ayinakuhlukanisa imibala ethile.
I-DVI iyanqamla kulo bunzulu bombala obu-24. Iinguqulelo ze-HDMI zakuqala nazo zikhawulelwe kulo mbala we-24-bit, kodwa nge-1.3 yobubanzi bemibala engama-30, 36 kunye ne-48-bit yongezwa. Oku kukwandisa kakhulu umgangatho osemgangathweni wombala onokuboniswa, kodwa zombini i-adapter i-graphics kunye neenyawo kufuneka zixhase i-HDMI version 1.3 okanye ngaphezulu. Ngokwahlukileyo, i-DisplayPort nayo yavelisa inkxaso yokwandiswa kombala ophezulu kunomlinganiselo wobunzulu be-48-bit.
Emuva iyahambelana
Enye yezinto ezibaluleke kakhulu ezibandakanyiweyo kwi-HDMI izinga elikwazi ukusetyenziswa kunye ne-DVI connectors. Ngokusebenzisa ikhebula le-adapter, i-plug ye-HDMI inokuqhotyoshelwa kwi-port ye-DVI ye-monitor yesignali yevidiyo. Oku kuyimpawu ebalulekileyo kulabo abathengayo inkqubo kunye ne-HDMI ekhutshweyo yevidiyo kodwa umboniso wabo we-TV okanye ikhompyutha unayo i-input input ye-DVI. Kufuneka kuqatshelwe ukuba oku kuphela isebenzisa inxalenye yevidiyo yekhebula le-HDMI ukuze akukho myalezo ungasetyenziswa nayo. Ukongeza, ngelixa i-monitor kunye ne-DVI isixhumi sinokuxhuma kwi-HDMI port port kwi khomputha, i-monitor ye-HDMI ayikwazi ukuxhuma kwi-DVI imifanekiso yecomputer.
I-DisplayPort ayinakho ukuguquguquka okuninzi kule ndawo. Ukuze usebenzise i-DisplayPort kunye nezinye izixhumo zevidiyo, ikhonkco esebenzayo ye-dongle iyadingeka ukuguqula uphawu lwevidiyo ukusuka kwi-Displayport standard ukuya kwi-HDMI, i-DVI okanye i-VGA. Ezi zixhumo zinokuba zibiza kakhulu kwaye ziyi-drawback enkulu kwikhonkco ye-DisplayPort.
Iinguqulelo ze 2.0
Ngokunyuka kwama- UltraHD okanye ii-4K Ukubonisa , kukho ezinye iimfuno ezinkulu zokuhamba kwee-bandwidth ukuze zithwale zonke iinkcukacha ezifunekayo kwisiboniso esiphezulu. Imigangatho ye-HDMI yangama-1.4 yakwazi ukunyuka ukuya kwiinqunto ezingama-2160p ezifunekayo kodwa kuphela kuma-30 ozimele ngeesibini. Oku kwakuyimpembelelo enkulu ekuthelekeni nemilinganiselo ye-DisplayPort. Ngombulelo, iqela leqela le-HDMI likhuphe i-version 2.0 ngaphambi kokuba ubuninzi beemiboniso ze-4K zifike kwiimakethi. Ukongeza kwimiba ephakamileyo yeerhafu kwizigqibo ze-UltraHD, iphinde isekele:
- Amandla okuba nemifudlana emibini yevidiyo (1080p) ethwele ikhebuli enye.
- Ukuphucula amaxabiso omlinganiselo wokuphulaphula umsindo.
- Ikhono lokuthwala imilambo emine yomsindo kubasebenzisi abaninzi kwikhebula elilodwa.
- Inkxaso ye-21: 9 imilinganiselo yevidyo yevidiyo yokubonisa isikrini.
- Umsindo onamandla ukuvumelanisa ngevidiyo.
- Inkxaso yomyalelo kunye nokwandiswa kolawulo lwe-multiple control control ngokusebenzisa isixhobo esisodwa.
Uninzi lwale mveliso alukahlanganiswa nakwii-computer zombane okanye iinkqubo zekhomputha kodwa zineempawu ezibonakalayo zabasebenzisi abangadinga ukwabelana ngefowuni, ukubonisa okanye ukusethwa komsindo.
Ngaba Umele Ukhangele i-HDMI kwi-Computer System?
Ngeli nqanaba, bonke abasebenzisi beekhomputha kunye nekhompyutheni bekhompyutha kufuneka bafike nge-HDMI port port standard. Oku kwenza kube lula ukuwasebenzisa kunye nabagadi bekhompyutheni be-digital standard kunye ne-HDTVs. Kufuneka kuqatshelwe ukuba kusekho iikhomputha zeklasi zebhajethi ezimbalwa kwiimarike ezingabonakali esi sixhobo. Ndingaziphepha ezi khompyutheni njengoko zinokuba yimfanelo kwixesha elizayo. Ukongeza kule nto, ezinye iikhomputha zeklasi zenkampani zingenakufaka ichwethi ye-HDMI kodwa kunoko, yiza ne-DisplayPort. Le yindlela efanelekileyo kodwa kufuneka uqinisekise ukuba unesigqeba esinokuxhasa eso sixhobo.
Ingxaki nge-HDMI inkxaso inkxaso ngakumbi kwiikhompyuter ze- tablet kunye nee-smartphone. Oku akuyona into enomgangatho kubo kodwa unokufuna inkxaso yesikhonkco esincinci okanye encinci ye-HDMI ukuze iqhutywe kwi-HDTV yokusakaza okanye ukudlala kwevidiyo.
