Lona umbuzo ohlupha abadlali abaningi bamageyimu: Ukuxhumeka kwe-HDMI noma kwe-DisplayPort? Yikuphi okungcono? Ziyizindinganiso ezimbili zokuxhuma ezisetshenziswa kakhulu zokudlulisa ividiyo yedijithali nomsindo phakathi kwamadivayisi. Owokuqala usetshenziswa kakhulu ukuzijabulisa kwasekhaya kanye nethiyetha yasekhaya; eyesibili isetshenziswa kakhulu ezindaweni ezichwepheshile noma ngaphezulu exhumene nobuchwepheshe bekhompyutha.
Ukuze uphendule umbuzo, kungcono ukubukeza ngokuningiliziwe ukuthi uhlobo ngalunye lokuxhuma lusebenza kanjani, ukukhomba izinzuzo zalo eziyinhloko nobuthakathaka. Ngakho ungakwazi ukunquma ukuthi iyiphi engcono kuwe.
Yini i-HDMI?
Okujwayelekile I-HDMI (High Definition Multimedia Interface ”) yethulwa ngo-2003 ukuze ixhunywe kumathelevishini edijithali / ama-HDTV kanye nezingxenye zetiyetha yasekhaya. Ividiyo, umsindo kanye namasignali okulawula anomkhawulo angadluliselwa kusetshenziswa izintambo ze-HDMI.
I-Los amadivaysi ezingasebenzisa ukuxhumana kwe-HDMI zimi kanje:
- Amakhamera edijithali, ama-camcorder nama-smartphone.
- Ama-consoles wegeyimu.
- Amabhokisi ekhebula / Isathelayithi nama-DVR.
- Abamukeli ekhaya cinema.
- Izidlali zeDVD, Blu-ray kanye ne-Ultra HD.
- Ama-TV namaphrojekhtha wevidiyo.
I-HDMI noma i-Displayport: izinzuzo kanye nokubi ngakunye
Izintambo ze-HDMI
Izintambo ze-HDMI zinikeza amandla ahlukene kuye ngesivinini sokudlulisa isignali (noma umkhawulokudonsa). Lezi yizinketho abasinika zona:
- Estándar- Ngokudluliswa kwevidiyo ngokulungiswa okufika ku-720p no-1080i, izinga lokudlulisa lifika ku-5 Gbps. Iyahambisana ne-HDMI izinguqulo 1.0 kanye ne-1.2a.
- Ijubane eliphezulu- Ukulungiswa kwevidiyo okungu-1080p kanye no-4K (30Hz), kanye nokusekelwa kwe-3D nombala Ojulile. Isivinini sokudlulisa komkhawulokudonsa sifika ku-10 Gbps. Iyahambisana ne-HDMI izinguqulo 1.3 kanye ne-1.4a.
- Isivinini esiphezulu se-Premium: inguqulo ethuthukisiwe yangaphambilini. Ilungele ukudluliswa kwevidiyo nge-4K / Ultra HD ukulungiswa okufika ku-4K / 60 Hz kanye ne-HDR enobubanzi bemibala enwetshiwe. Isivinini sokudlulisa singafika ku-18 Gbps. Iyahambisana nezinguqulo ze-HDMI 2.0.
- Isivinini esiphezulu kakhulu- Ukulungiswa kwevidiyo kufika ku-8K nge-HDR. Isivinini sokudlulisa sifika ku-48 Gbps. Iphinde inikeze ukuvikeleka okukhulu ekuphazamiseni kazibuthe kagesi okubangelwa ezinye izisetshenziswa ezingenantambo futhi ihambisana nenguqulo ye-HDMI engu-2.1.
Kukhona futhi amamodeli we Izintambo ze-HDMI zezimoto, esetshenziselwa kakhulu ukuxhuma amadivayisi kuzikrini zevidiyo ngaphakathi kwezimoto.
Izixhumi
Ikhebula le-HDMI linganikeza uhlobo olulodwa noma eziningi zesixhumi sokugcina:
- Thayipha u-A- Ngoxhumo olusuka ku-DVD, i-Blu-ray, izidlali ze-Ultra HD, ama-PC, amakhompyutha aphathekayo, ama-media streamer, namakhonsoli egeyimu kuya kumathelevishini, ama-video projektha, izamukeli zetiyetha yasekhaya, nezinye izisetshenziswa.
- Okuncane (uhlobo C): yiyona esetshenziswa kakhulu kumakhamera e-DSLR namathebulethi efomethi enkulu.
- Thayipha D- Sizithola kumakhamera amancane edijithali, ama-smartphones kanye namathebulethi.
- Isixhumi sezimoto (uhlobo E).
Iyini i-DisplayPort?
Isistimu yokuxhumana I-DisplayPort (DP) Sekudlule isikhathi kune-HDMI, njengoba yethulwa ngo-2006. Bekuyisistimu eklanywe ngabakwa-VESA (I-Video Electronics Standards Association) ngenhloso yokushintsha ukuxhumana kwe-VGA ne-DVI, izintambo nezixhumi ezisetshenziswa kakhulu ukuxhuma i-PC ngemonitha.
I-HDMI noma i-Displayport: izinzuzo kanye nokubi ngakunye
Ngokungeziwe ezithombeni, i-DisplayPort ingaphatha namasignali alalelwayo. Nokho, uma idivayisi yesibonisi inganikezi isistimu yesipika noma okokukhiphayo kusistimu yomsindo yangaphandle, isignali yomsindo ayifinyeleleki.
I-Los amadivaysi ezingasebenzisa i-DisplayPort uxhumano yi-PC, i-Mac, iziqapha kanye nazo zonke izinhlobo zamadivayisi eselula. Uxhumano lwe-DP luphinde luhambisane namadivayisi anezinye izinhlobo zokuxhuma, njenge-VGA, i-DVI ne-HDMI, njalo ngosizo lwe-adaptha.
Izintambo ze-DisplayPort
Izici ezijwayelekile ze-DisplayPort izinguqulo ezinhlanu ezahlukene zekhebula. Ngenhlanhla, inguqulo ngayinye entsha evelayo iyahambisana neyangaphambili. Lawa alandelayo, abhalwe ngokonyaka akhululwa ngawo:
- BonisaPort 1.0 (2006): Ukulungiswa kwevidiyo kufika ku-4K / 30 Hz. Izinga lokudlulisela lifika ku-8,64 Gbps HBR1 (Izinga eliphezulu le-Bitrate 1).
- BonisaPort 1.1 (2007): Ifana nenguqulo yangaphambilini kuyo yonke imingcele yayo, kodwa ngokuthuthukiswa okufana ne-HDCP (ukuvikelwa kwekhophi kwencazelo ephezulu).
- BonisaPort 1.2 (2009): Ukulungiswa kwevidiyo kukhuphukela ku-4K / 60 Hz. Kuphinde kuhlanganise nenketho yokudlulisela okuningi okuzimele (I-Multi-Stream Transport noma i-MST) kanye nezinga lokudluliswa kwedatha yevidiyo elifika ku-17.28 Gbps, ngaphezu kwezinye izici ze-HBR2 (Izinga eliphezulu le-Bitrate 2).
- BonisaPort 1.3 (2014): Iminikelo yayo eyinhloko ihambisana ne-HDMI, i-HDCP 2.2 kanye nesivinini sokudlulisa esingu-25.92 Gbps kanye nezinye izici ze-HBR3 (Izinga Le-Bitrate Eliphezulu 3).
- BonisaPort 1.4 (2016): Ukulungiswa okuphezulu kwevidiyo, kufika ku-8K / 60 Hz.
Izixhumi ze-DisplayPort
Kunezinhlobo ezimbili kuphela zezixhumi ze-DisplayPort: usayizi ojwayelekile kanye ne-mini. Esokuqala sande kakhulu kunesesibili. Isixhumi I-DisplayPort encane (i-MiniDP noma i-mDP) yethulwa kanye nenguqulo 1.2 yekhebuli ye-DisplayPort ngo-2009. Lesi sixhumi sivame ukutholakala kuma-Mac nakwamanye amadivaysi e-Apple, nakuba singasetshenziswa nezinye izinguqulo zezintambo ngokusebenzisa ama-adaptha.
Ukuqhathanisa: I-HDMI noma i-DisplayPort
I-HDMI noma i-Displayport: izinzuzo kanye nokubi ngakunye
Ngokusekelwe kulo lonke ulwazi olunemininingwane ezigabeni ezedlule, sekuyisikhathi sokuqhathanisa zombili izindinganiso zokuxhuma: i-HDMI noma i-DisplayPort. Yikuphi okumele ukhethe? Kokubili kunezinzuzo ezinkulu nezinye izici ezingezinhle kangako. Ake siziqhathanise ukuze sinqume ukuthi iyiphi esilungele:
Ividiyo nomsindo
Umthamo wokudluliswa kwevidiyo we-DisplayPort uphakeme kancane kunalowo we-HDMI. Lokhu kungenxa yokuthi isekela izintambo ze-fiber optic njengenye indlela kunethusi. Ngokuphambene, awukho umehluko obonakalayo emsindweni: womabili amazinga asekela iziteshi eziyisishiyagalombili zomsindo we-24-bit 192 KHz.
Uxhumano lwekhompyutha-TV
Akuwona wonke amabhrendi we-TV namamodeli anikeza uxhumano lwe-DisplayPort. Ngakho, ukuxhuma umthombo we-DisplayPort kumabonakude efakwe okokufaka kwe-HDMI (okungafani ne-DP, ikuwo wonke amabhrendi), uzodinga i-adaptha.
Amasistimu anezikrini eziningi
Ngakolunye uhlangothi, kulo mkhakha i-DisplayPort iphakeme ngokusobala kune-HDMI sibonga ikhono layo lokukhipha okuqukethwe kwevidiyo kuzibonisi eziningi ngobuchwepheshe be-Multi-Stream Transport (MST). Le port ingalungiswa ukuze izibonisi ziboshwe ngamaketango. Lokhu kuyinto i-HDMI enganikezi okwamanje.
Gaming
Uma sikhuluma ngokuxhunywa kokudlala nge-PC yethu, sibhekene nethayi yezobuchwepheshe. I-DisplayPort ibilokhu iyinkomba yanoma yimuphi umdlali eminyakeni yamuva, kodwa lokhu kushintshile ngokufika kwe-HDMI 2, eshiye izinto ngisho nakakhulu. Kunoma ikuphi, lapho ukhetha phakathi kwe-DisplayPort noma i-HDMI kubalulekile ukuthi uhlole izinguqulo zazo ngayinye, ngoba zinikeza izici ezihlukile.
Njengoba ubona, akunakushiwo ngokuphelele ukuthi indinganiso eyodwa yokuxhuma ingcono kunenye. Ukuzikhethela kuncike ezidingweni zethu.
