Lo ngumbuzo ophazamisa iingqondo zabadlali abaninzi: Uqhagamshelo lweHDMI okanye iDisplayPort? Yeyiphi engcono? Zezona migangatho zimbini zoqhagamshelo zisetyenziswa kakhulu ekudluliseleni ividiyo yedijithali kunye nesandi phakathi kwezixhobo. Eyangaphambili isetyenziswa kakhulu kulonwabo lwasekhaya kunye nethiyetha yasekhaya; eyesibini isetyenziswa kakhulu kwiindawo zobuchwephesha okanye ezidityaniswe ngakumbi kubuchwephesha bekhompyuter.
Ukuphendula umbuzo, kungcono ukuphonononga ngokweenkcukacha ukuba uhlobo ngalunye loxhulumaniso lusebenza njani, ukuchonga iinzuzo zalo eziphambili kunye nobuthathaka. Ngoko unokugqiba ukuba yeyiphi eyona ikulungeleyo.
Yintoni i-HDMI?
Umgangatho HDMI (I-High Definition Multimedia Interface ”) yaziswa ngo-2003 ukuze idityaniswe koomabonakude bedijithali / ii-HDTV kunye namacandelo ethiyetha yasekhaya. Ividiyo, isandi kunye nemiqondiso yolawulo olulinganiselweyo inokuhanjiswa kusetyenziswa iintambo zeHDMI.
Los zixhobo enokusebenzisa uqhagamshelo lweHDMI ngolu hlobo lulandelayo:
- Iikhamera zedijithali, iikhamera kunye nee-smartphones.
- Iintuthuzelo zomdlalo.
- Ikhebula / iibhokisi zeSathelayithi kunye neeDVR.
- Abamkeli icinema yasekhaya.
- DVD, Blu-ray kunye nabadlali be-Ultra HD.
- Oomabonakude kunye neeprojektha zevidiyo.
I-HDMI okanye iDisplayport: iingenelo kunye nokungeloncedo ngakunye
Iintambo ze-HDMI
Iintambo ze-HDMI zibonelela ngezakhono ezahlukeneyo ngokuxhomekeke kwisantya sokudlulisa umqondiso (okanye i-bandwidth). Olu lukhetho abasinika lona:
- Estándar-Ukuhanjiswa kwevidiyo ngesisombululo ukuya kuthi ga kwi-720p kunye ne-1080i, izinga lokudlulisela ukuya kuthi ga kwi-5 Gbps. Iyahambelana ne-HDMI iinguqulelo ze-1.0 kunye ne-1.2a.
- Isantya esiphezulu- I-1080p kunye ne-4K (30Hz) izigqibo zevidiyo, kunye ne-3D kunye nenkxaso yoMbala onzulu. Isantya sokudlulisa i-bandwidth sifikelela kwi-10 Gbps. Iyahambelana ne-HDMI iinguqulelo ze-1.3 kunye ne-1.4a.
- Isantya esiphezulu esiphezulu: inguqulelo ephuculweyo yangaphambili. Ilungele ukuhanjiswa kwevidiyo nge-4K / Ultra HD isisombululo ukuya kuthi ga kwi-4K / 60 Hz kunye ne-HDR enoluhlu lombala olwandisiweyo. Isantya sokudlulisa sifikelela kwi-18 Gbps. Iyahambelana neHDMI 2.0 iinguqulelo.
- Isantya esiphezulu kakhulu-Isisombululo sevidiyo ukuya kuthi ga kwi-8K eneHDR. Isantya sokutshintshela ukuya kuthi ga kwi-48 Gbps. Ikwabonelela ngokhuseleko olukhulu ngokuchasene nokuphazamiseka kwe-electromagnetic okubangelwa zezinye izixhobo ezingenazingcingo kwaye iyahambelana ne-HDMI version 2.1.
Kukho neemodeli ze Iintambo zeHDMI zeemoto, ikakhulu esetyenziselwa ukudibanisa izixhobo kwizikrini zevidiyo ngaphakathi kwezithuthi.
Iziqhagamshelo
Intambo ye-HDMI inokubonelela ngodidi olunye okanye ngaphezulu kwesidibanisi sesiphelo:
- Uhlobo A-Kuqhagamshelo olusuka kwiDVD, iBlu-ray, abadlali beUltra HD, iiPC, iilaptops, imidiya esasaza, kunye nemidlalo yekhonsoli koomabonakude, iiprojektha zevidiyo, abamkeli bethiyetha yasekhaya, kunye nezinye izixhobo.
- Ubuncinci (uhlobo C): yeyona isetyenziswa kakhulu kwiikhamera ze-DSLR kunye neetafile ezinkulu zefomathi.
- Uhlobo D-Sizifumana kwiikhamera ezincinci zedijithali, ii-smartphones kunye neetafile.
- Isidibanisi seemoto (uhlobo E).
Yintoni iDisplayPort?
Inkqubo yoqhagamshelwano Umboniso wePort (DP) Kuthe emva kwexesha kune-HDMI, njengoko yaziswa ngo-2006. Yayiyinkqubo eyilwe yiVESA (Umbutho weMigangatho yezoMbane zeVidiyo) ngenjongo yokutshintsha i-VGA kunye ne-DVI uxhulumaniso, iintambo kunye nezixhumi ezisetyenziselwa ikakhulu ukudibanisa i-PC kunye ne-monitor.
I-HDMI okanye iDisplayport: iingenelo kunye nokungeloncedo ngakunye
Ukongeza kwimifanekiso, iDisplayPort inokuphinda iphathe iimpawu zomsindo. Nangona kunjalo, ukuba isixhobo sokubonisa asiboneleli ngenkqubo yesithethi okanye imveliso kwisixokelelwano somsindo sangaphandle, isignali ye-audio ayifikeleleki.
Los zixhobo enokusebenzisa uqhagamshelo lweDisplayPort yiPC, iMac, iimonitha kunye nazo zonke iintlobo zezixhobo eziphathwayo. Uxhulumaniso lwe-DP luyahambelana nezixhobo ezinezinye iintlobo zokudibanisa, ezifana ne-VGA, i-DVI kunye ne-HDMI, rhoqo ngoncedo lwe-adapter.
Iintambo zePortPort
Iimpawu eziqhelekileyo zeDisplayPort iinguqulelo ezintlanu ezahlukeneyo cable. Ngethamsanqa, inguqulelo nganye entsha eye yavela iyahambelana nezi zangaphambili. Ezi zilandelayo, zidweliswe ngokonyaka wokukhululwa kwazo:
- Bonisa iPort 1.0 (2006): Isisombululo sevidiyo ukuya kuthi ga kwi-4K / 30 Hz. Izinga lokutshintshela ukuya kuthi ga kwi-8,64 Gbps HBR1 (iNqanaba eliphezulu le-Bitrate 1).
- Bonisa iPort 1.1 (2007): Ngokufana nenguqulo yangaphambili kuzo zonke iiparameters zayo, kodwa ngokuphuculwa okufana ne-HDCP (inkcazo ephezulu yokukhusela ikopi).
- Bonisa iPort 1.2 (2009): Isisombululo sevidiyo sinyuka ukuya kwi-4K / 60 Hz. Ikwabandakanya ukhetho lwezothutho ezininzi ezizimeleyo (i-Multi-Stream Transport okanye i-MST) kunye nesantya sokudlulisa idatha yevidiyo ukuya kwi-17.28 Gbps, kunye nezinye iimpawu ze-HBR2 (Inqanaba le-Bitrate ephezulu ye-2).
- Bonisa iPort 1.3 (2014): Igalelo layo eliphambili lihambelana ne-HDMI, i-HDCP 2.2 kunye nesantya sokudlulisa i-25.92 Gbps kunye nezinye iimpawu ze-HBR3 (i-High Bitrate Level 3).
- Bonisa iPort 1.4 (2016): Isisombululo esiphezulu sevidiyo, ukuya kuthi ga kwi-8K / 60 Hz.
Iziqhagamshelo zeDisplayPort
Kukho iintlobo ezimbini kuphela ze-DisplayPort connectors: ubungakanani obuqhelekileyo kunye ne-mini. Eyokuqala ixhaphake kakhulu kuneyesibini. Isidibanisi iDisplayPort encinci (iMiniDP okanye mDP) yaziswa kunye nenguqulo 1.2 yentambo ye-DisplayPort ngo-2009. Esi siqhagamshelo sihlala sifumaneka kwi-Macs kunye nezinye izixhobo ze-Apple, nangona inokusetyenziswa kunye nezinye iinguqulelo zeentambo ngokusetyenziswa kwee-adapters.
Ukuthelekisa: I-HDMI okanye i-DisplayPort
I-HDMI okanye iDisplayport: iingenelo kunye nokungeloncedo ngakunye
Ngokusekelwe kulo lonke ulwazi oluchazwe kwimihlathi yangaphambili, lixesha lokuthelekisa zombini imigangatho yoqhagamshelwano: i-HDMI okanye i-DisplayPort. Yeyiphi oyikhethayo? Zombini zineengenelo ezinkulu kunye nezinye izinto ezingezizo ezintle. Masizithelekise ukuze sigqibe ukuba yeyiphi eyona ilungileyo kuthi:
Ividiyo kunye nesandi
Umthamo wokuhanjiswa kwevidiyo weDisplayPort ungaphezulu kancinane kuneHDMI. Oku kungenxa yokuba ixhasa iintambo zefiber optic njengenye indawo kunobhedu. Kwelinye icala, akukho mahluko ubonakalayo kwiaudiyo: yomibini imigangatho ixhasa ukuya kuthi ga kwiitshaneli ezisibhozo ze-24-bit 192 KHz yomsindo.
Uqhagamshelo lweKhompyutha-TV
Ayizizo zonke iimpawu zeTV kunye neemodeli ezibonelela ngoqhagamshelo lweDisplayPort. Ngaloo ndlela, ukudibanisa umthombo we-DisplayPort kumabonwakude oxhotyiswe nge-HDMI inputs (engafaniyo ne-DP, kuzo zonke iimpawu), uya kufuna i-adapter.
Iinkqubo ezininzi zesikrini
Ngakolunye uhlangothi, kule ntsimi i-DisplayPort ingaphezulu ngokucacileyo kwi-HDMI sibonga amandla ayo okuvelisa umxholo wevidiyo kwiziboniso ezininzi ngeteknoloji ye-Multi-Stream Transport (MST). Eli zibuko lingaqwalaselwe ukuze iziboniso zibotshwe ngamatyathanga. Le nto i-HDMI ayinikezeli okwangoku.
Gaming
Ukuba sithetha ngonxibelelwano lokudlala kunye nePC yethu, sijongene neqhina lobugcisa. I-DisplayPort ibe yireferensi kuyo nayiphi na i-gamer kwiminyaka yakutshanje, kodwa oku kwatshintsha ngokufika kwe-HDMI 2, eshiye izinto kakhulu. Kwimeko nayiphi na into, xa ukhetha phakathi kweDisplayPort okanye i-HDMI kubalulekile ukujonga iinguqulelo zabo nganye, kuba zibonelela ngezinto ezahlukeneyo.
Njengoko ubona, akunakuchazwa ngokupheleleyo ukuba umgangatho wonxibelelwano ungcono kunomnye. Ukhetho luxhomekeke kwiimfuno zethu.
