Isingeniso
Ngokuphakama kokuqukethwe kwevidiyo ephezulu-definition kanye nokwamukelwa kwe-HDTV, isidingo se-connector ehlanganisiwe ejwayelekile sasidinga. I-interface ye-DVI yasungulwa ekuqaleni kwezinhlelo zekhompuyutha futhi yafakwa kumadivaysi e-HDTV ekuqaleni, kodwa kunamanani okulinganiselwa ngayo lapho abakhiqizi babheka ukuhlanganisa isixhumi esisha. Kusukela kulokhu, i-High-Definition Mulconedia Interconnect noma i-HDMI amazinga athuthukile okuye kwaba yi-connecto video connector.
Izixhumanisi ezincane ezimisiwe
Enye yezinzuzo ezinkulu ze-HDMI isikhombimsebenzisi phezu kwesikhombikubona se-DVI ubukhulu bomxhumanisi. I-interface ye-DVI ifana nobukhulu ku-VGA interface ephakathi kwengu-1.5 amasentimitha ububanzi. Isixhumi se- HDMI esilinganiselwe cishe ingxenye eyodwa yesithathu ubukhulu bomxhumanisi we-DVI. I-HDMI version 1.3 incazelo yokwesekwa okungeziwe yesikhulumi esincane esincane se-HDMI esasizosiza ama-laptops amancane kakhulu kanye ne-electronics abasebenzisi abancane njengamakhamera. Nge-HDMI version 1.4, isixhumi esincane se-HDMI sanezelwa nomxhumo omncane kakhulu owawusizo ekusetshenzisweni okukhulayo kwamadivayisi we-tablet ne-smartphone.
Umsindo nevidyo kuChebula elilodwa
Izinzuzo zekhebula ze-HDMI zisho nakakhulu nge-DVI ngoba i-HDMI nayo iphethe umsindo wedijithali. Ngamakhompyutha amaningi asekhaya asebenzisa okungenani oyedwa futhi angakwazi ukufika kumakholi amathathu-jack ukuze asebenzise umsindo avela kuwo izikhulumi, ikhebula le-HDMI lenza inani lamakhodi lidinga ukuphatha isignali yomsindo kumqapha. Ekusebenziseni kwe-HDMI yokuqala yamakhadi ehluzo, ama-nonsthrough connectors asetshenziselwa ukwengeza ukusakazwa komsindo kumakhadi wegrafu kodwa iningi manje linamashayela omsindo wokusingatha kokubili umsindo nomculo ngesikhathi esifanayo.
Ngesikhathi umsindo nevidiyo kwikhebula elilodwa lihlukile uma i-HDMI isungulwe kuqala, lesi sici safakwa futhi kwisixhumanisi sevidiyo se- DisplayPort . Kusukela lokho kwenzekile, iqembu le-HDMI liye lasebenza ekukhuliseni ukusekelwa komsindo owengeziwe wesiteshi. Lokhu kubandakanya umsindo we-7.1 ku-HDMI version 1.4 futhi manje kuze kube yiziteshi ezingu-32 zomsindo nge-HDMI version 2.0 yakamuva.
Ukwanda koMbala okwandisiwe
Umbala we-Analog nedijithali wekhompyutha ye-PC sekuyisikhathi eside uvinjelwe kumbala we-24-bit okhiqiza imibala eyizigidi ezingu 16.7. Lokhu ngokuvamile kubhekwa njengombala weqiniso ngoba iso lomuntu alikwazi ukuhlukanisa phakathi kwe-shades kalula. Ngesinqumo esandisiwe se-HDTV , iso lesintu lingasho umehluko kukho konke umbala wombala phakathi kokujula kombala wama-24-bit namazinga aphezulu, ngisho noma engakwazi ukuhlukanisa imibala ngayinye.
I-DVI ilinganiselwe kulokhu ukujula kombala we -24-bit. Izinguqulo ze-HDMI zakuqala nazo zikhawulelwe kulo mbala we-24-bit, kodwa ngezinguquko ezingu-1.3 zezinhlobo ezingu-30, 36 kanye nama-48-bit. Lokhu kukhulisa kakhulu ikhwalithi yonke yombala ongaboniswa, kodwa kokubili i-adapter ihluzo neqapha kufanele zisekele i-HDMI version 1.3 noma ngaphezulu. Ngokuphambene, i-DisplayPort iphinde ithule ukwesekwa kokujula kombala okwandisiwe kuze kufike ekujuleni kombala we-48-bit.
Emuva iyahambisana
Esinye sezici ezibaluleke kakhulu ezifakwe ngezinga le-HDMI yikhono layo lokusetshenziswa nezixhumi ze-DVI. Ngokusebenzisa ikhebula le-adapter, i-plug ye-HDMI ingaxhunywe ku-port ye-DVI ye-monitor yesignali yevidiyo. Lesi isici esiwusizo kakhulu kulabo abathenga uhlelo nge-HDMI okukhiphayo okukhiphayo kodwa umbukiso wethelevishini noma ikhompiyutha kuphela onokufaka kwe-DVI. Kumele kuqashelwe ukuthi lokhu kusebenzisa kuphela ingxenye yevidiyo yekhebula le-HDMI ngakho akukho myalezo ongasetshenziswa nawo. Ngaphezu kwalokho, ngenkathi i-monitor ne-connector ye-DVI ingaxhuma kwi-HDMI port port, ikhompiyutha ye-HDMI ayikwazi ukuxhuma kwi-port ihluzo le-DVI kukhompyutha.
I-DisplayPort ayinayo ukuguquguquka okuningi kule ndawo. Ukuze usebenzise i-DisplayPort namanye amaxhumo wevidyo, i-dongle ixhuma esebenzayo iyadingeka ukuguqula isignali yevidiyo kusukela ku-Displayport standard kuya ku-HDMI, i-DVI noma i-VGA. Lezi zixhumanisi zingaba zibiza kakhulu futhi kuyinhloko enkulu ekuxhumaneni kwe-DisplayPort.
Izinguqulo ze-Version 2.0
Ngokuphakama kwe- UltraHD noma i-4K Ekhombisa , kunesidingo esikhulu se-bandwidth ukuze sithwale yonke idatha edingekayo ekubonisweni okuphezulu. Amazinga we-HDMI version 1.4 akwazi ukufika ezinqumweni ezingu-2160p ezidingekayo kodwa kuphela kuma-30 ozimele ngomzuzwana. Lokhu kwakuyisiphambeko esikhulu uma kuqhathaniswa namazinga we-DisplayPort. Ngokujabulisayo, iqembu le-HDMI elisebenzayo likhishwe inguqulo ye-2.0 ngaphambi kokuba isibonakaliso se-4K sifike emakethe. Ngaphandle kwamazinga aphezulu ohlakeni ezinqumweni ze-UltraHD, ibuye isekele:
- Amandla okuba nemifudlana yevidiyo emibili (1080p) ethathwe ngaphezu kwekhebula elilodwa.
- Amazinga wokulinganisa okulalelwayo okuthuthukisiwe ekuthuthukiseni ukuthembeka kwezwi.
- Amandla okuphatha imifudlana emine yomsindo kubasebenzisi abaningi kwikhebula elilodwa.
- Ukusekela ividiyo engu-21: 9 ye-aspect ratio ukuze kuboniswe izibuko ezibukwayo.
- I-Dynamic umsindo ukuvumelanisa kwevidiyo.
- Ukusekela izandiso zokulawula nokulawula ukulawula okuningi kwedivayisi ngokusebenzisa idivayisi eyodwa.
Iningi lalezi zici akukafaneli lihlanganiswe kumakhompiyutha omthengi wekhaya noma izinhlelo zekhompyutha kodwa zinekhono elikhulu labasebenzisi abangase badinge ukwabelana ngedivaysi yekhompyutha, ukubonisa noma ukusetha umsindo.
Ingabe Kufanele Uhlole i-HDMI ku-Computer System?
Kuleli qophelo, wonke amakhompiyutha e-laptop nabathengi bekhompuyutha kufanele eze ngezinga le-HDMI port. Lokhu kwenza kube lula ukuwasebenzisa ngezindinganiso ezijwayelekile zekhompyutha yakho ye-digital kanye nama-HDTV. Kumele kuqashelwe ukuthi kusekhona amakhompiyutha amancane esigaba sebhajethi emakethe engayifaki lesi sixhumano. Ngingazigwema ngokucophelela lezi makhamera ngoba kungaba yindleko esikhathini esizayo. Ngaphezu kwalokhu, amanye amakhompiyutha eklasi ezinkampani angahle angafaki i-HDMI port kodwa esikhundleni salokho, eze ne-DisplayPort. Lokhu kuyindlela efanelekayo kodwa kufanele uqiniseke ukuthi unomqapha ongasisekela lo mxhuma.
Inkinga ngokusekelwa kwe-HDMI kungaphezulu kwamakhompyutha we- tablet nama-smartphone. Lokhu akuyona into ejwayelekile kubo kodwa ungase ufune ukwesekwa kwesikhamera se-micro noma esincane se-HDMI ukuze sikhishwe ku-HDTV yokusakaza noma ukudlala okuqukethwe kwevidyo.
