Siyini isixhumi se-DisplayPort, sibukeka kanjani futhi kungani sisetshenziswa

Isixhumi se-DisplayPort (DP) namuhla siyisixhumi esibonakalayo esidumile, esisetshenziswa njalo esiklanyelwe ukuxhuma ubuchwepheshe besimanje, ama-TV, iziqapha. Lesi sikhombimsebenzisi esiqhubekayo, sesimanje sikuvumela ukuthi uthole ukuxhumana kwekhwalithi ephezulu lapho uxhuma okokusebenza komsindo noma kwevidiyo.
Kodwa-ke, ezimweni eziningi, i-DisplayPort isetshenziswa abasebenzisi uma kudingekile ukuxhuma izibonisi ezihlukahlukene, iziqapha noma amathiyetha asekhaya, ama-TV ku-PC yasekhaya (ideskithophu) noma i-laptop. Ngokusebenzisa lesi sikhombimsebenzisi sesimanje, umsebenzisi angadlulisela izinto zedijithali, okuqukethwe kumadivayisi ezinkampani zangaphandle kuyilapho egcina ukulungiswa okuphezulu (kufika ku-8K).

Incazelo yechweba kanye nobubanzi balo

Namuhla, abasebenzisi abaningi, imvamisa, basebenzisa i-DP ezimeni lapho kudingekile ukuxhuma amamodeli wokuqapha wesimanje ku-PC. Ngaphezu kwalokho, le port ilungile ezimeni lapho udinga ukuxhuma i-TV kudeskithophu. Kwezinye izimo, i-DisplayPort (DP) isetshenziswa ngokusebenzayo lapho kuxhunywa ama-acoustics noma amanye amadivaysi emidiya. Ngokungeziwe ezintweni ezinemifanekiso, leli chweba liyakwazi ukudlulisa amathrekhi alalelwayo nezinto ezilalelwayo kwamanye amadivaysi. Ngenxa yokusebenzisa i-DP, umsebenzisi angaxhuma imonitha engaphezu kweyodwa ku-PC yakhe ngesikhathi esisodwa. Kumele kuqashelwe ukuthi ngenxa yomkhawulokudonsa ophezulu wamachweba, ukudluliswa kwezithombe kubaqaphi kungenzeka ezinqumweni eziphezulu ezivunyelwe namuhla (2K, 4K).

Yiziphi izinhlobo zezixhumi ze-DisplayPort ezikhona

Kunezinhlobo eziningana ezahlukene zezixhumi eziza ne-DisplayPort. Lezi zixhumi ziyizi:

1. Okujwayelekile (usayizi ogcwele) . Njengomthetho, cishe wonke amamodeli wesimanje TV, amakhompyutha siqu, laptops ifakwe esibonakalayo esinjalo. Kuze kube manje, yilolu hlobo lwesici sefomu oluthole ukusatshalaliswa okubanzi kakhulu futhi lusetshenziswa kakhulu.
2. I- DP encane . Inguqulo encane yembobo yokubonisa evamile. Izixhumi zalolu hlobo zivame ukuhlonyiswa ngemishini ephathekayo, ephathekayo. Isibonelo, amamodeli wesimanje amaphilisi kanye netbooks ngokuvamile ifakwe mini DP port.

Akuzona zonke izixhumi ze-DP mini ezifakwe amadivayisi akhethekile, izinto zokulungisa (ukuvimbela). Nokho, kuzo zonke izixhumi ezibonakalayo zembobo ezinosayizi ogcwele, into enjalo yokukhiya ivamise ukuba khona.

Imininingwane yesixhumi

Isici samachweba okubonisa amandla kagesi aphansi kanye nokuphazamiseka okuphansi okungaphandle. Uma kuqhathaniswa ne-DVI evamile, i-DP yesimanje inomkhawulokudonsa ongcono kakhulu (cishe kabili). Ngesikhathi esifanayo, kufanele kuqashelwe ukuthi inguqulo encane yembobo yokubonisa ngobukhulu bayo cishe izikhathi eziyishumi ezincane kunesixhumi esivamile sohlobo lwe-DVI.
Akuyona into engafanele ukusho ukuthi i-DisplayPort ingadlulisela kanyekanye amasiginali wevidiyo, kanye nefomethi yomsindo. Izinga lokuphuma phambili lamamodeli e-DP okuqala lalingu-9Gbps. Izinga lokudlulisa lamamodeli amasha ezimbobo ezinjalo liyahlukahluka kufika ku-29 Gb / s.

Kuyaphawuleka! Ubude obuphelele bekhebula le-DP elisetshenziselwa ukuxhuma ku-PC nokudlulisa isignali akufanele budlule amamitha angu-15. Ngesikhathi esifanayo, ikhebula ende (15 m) iyakwazi ukudlulisa isithombe ngekhwalithi ye-Full HD. Ukuze uthole ukulungiswa okuphezulu kwesithombe esidlulisiwe, kunconywa ukusebenzisa izintambo ezincane ze-DP (kufika ku-3 m).

Izixhumi ze-DP zifakwe izikhonkwane ezingu-20 futhi ziyakwazi ukudlulisa imifudlana yolwazi zisebenzisa iziteshi ezi-4. Kuyaphawuleka ukuthi futhi ngaphezu kwalokho ifakwe okuthiwa isiteshi sobuchwepheshe (kufika ku-800 Mbps). Ubukhulu bokulungiswa okunokwenzeka kwesibonisi sembobo ye-DP (inguqulo 1.4) sifinyelela ku-7680×4320.

Izinzuzo kanye nokubi echwebeni

Izimbobo zokubonisa (DP) zinakho kokubili okuhle nokubi. Izinzuzo zalesi interface zihlanganisa:

• ukuba khona kwesixhumi esikhethekile nokukhetha ukuzikhiya;
• ibethela ngokuphephile idatha;
• iyahambisana nezibonisi zokucaca okuphezulu;
• ilungele ukuxhumeka ngesikhathi esisodwa kwabaqaphi abaningana ngesikhathi esisodwa;
• ukuba khona kwesistimu elula yokulungisa izixhumi;
• ifakwe ngesivinini esiphezulu, isiteshi esingeziwe esiyisizayo.

Ukungalungi kwamachweba okubonisa kufaka phakathi iqiniso lokuthi abakwazi ukusebenza ngokugcwele ngekhebula elide kakhulu (ukuze udlulise isithombe sekhwalithi ephezulu nesinqumo, kunconywa ukusebenzisa ikhebula elingekho ngaphezu kwamamitha angu-3). Ngaphezu kwalokho, namuhla akuwona wonke amadivaysi esimanje asekela ukusebenza futhi afakwe lesi sixhumi. Kodwa-ke, ukuxhuma i-multimedia nezinye izinto zokusebenza ezingafakelwe isixhumi sesimanje se-DisplayPort, ungasebenzisa ama-adaptha akhethekile. Phakathi kwabasebenzisi, amadivaysi akhethekile adingeka kakhulu – ama-adaptha asuka ku-DP kuya kwizixhumi ezifana ne-HDMI, noma ku-VGA ejwayelekile, evamile.

Imibandela Yokukhetha Ikhebula le-DisplayPort

Zonke izinhlobo ezahlukene zezintambo ze-DP zihambisana namadivayisi afakwe imbobo yokubonisa. Ukuhambisana nokusebenzisana akuthintwa inguqulo yesixhumi esibonakalayo esisetshenzisiwe, noma izinga lesitifiketi. Ngakho-ke, uma usebenzisa noma iyiphi ikhebula le-DisplayPort, ngenxa yokuthi uhlelo olulodwa lokuxhuma oluyisisekelo lusetshenziswa, yonke imisebenzi ehlinzekwa yilesi sikhombimsebenzisi izogcinwa.

Yiziphi izici okufanele zilandelwe lapho kukhethwa ikhebula le- displayport (DP)?

Ngesikhathi sokukhethwa kwezintambo ze-DP, kufanele kucatshangelwe ukuthi zingase zibe namazinga ahlukene ejubane lokudlulisa ulwazi lokuqala. Sekukonke, imbobo yokubonisa ingasebenza ngezindlela ezi-4 zokudlulisa ulwazi: HBR3, HBR2, HBR, ne-RBR. Kunezinhlobo eziningana zezitifiketi (ukuqinisekiswa okunjalo akudingekile, futhi izintambo ezidlulisiwe zimakwe ngokufanele), ezingasetshenziswa ukucacisa ukuphuma kwekhebula elisetshenzisiwe. Ngokuvumelana namazinga wokuqinisekisa ngokuvamile amukelwayo, izintambo ezisetshenziswa ukuxhuma ngezimbobo zokubonisa yilezi:

1. Okujwayelekile . Iyakwazi ukudlulisa ulwazi ngokushesha. Ijubane le-HBR lifika ku-10 Gb / s, futhi ku-HBR2 – alikho ngaphezu kuka-21.60 Gb / s.
2. Izintambo ze-RBR . Ahlukaniswa ngezinga eliphansi lokudlulisa ulwazi (akukho ngaphezu kuka-6.48 Gbps).
3. Ikhebula le-DP8K . Iyakwazi ukudlulisa idatha ngesivinini esikhulu (akukho ngaphezu kuka-32.40 Gbps).

Ngokwezinga le-DisplayPort, ubude (okusho inani layo eliphezulu) lekhebula ledatha elisetshenzisiwe abuchazwa. Kodwa-ke, ngokwezindinganiso ezamukelwe i-DisplayPort 1.2, le nto yefomu inezidingo ezincane ngokosayizi nezinga lokudlulisela kolwazi lwangempela (amakhebuli afinyelela kumamitha angu-2 ubude kufanele asekele isivinini esifika ku-21.6 Gb/s). https://youtu.be/7n9IQ_GpOlI

Izidingo ezijwayelekile kanye nemithetho yokuxhuma

Okusha futhi kancane kancane okuthola ukuthandwa phakathi kwabasebenzisi yi-interface ye-DisplayPort, namuhla ebhekwa njengenye yezimbangi eziyinhloko zesixhumi sesimanje nesaziwayo se-HDMI. Ngenxa yokusebenzisa i-DP, umsebenzisi angaxhuma ngesikhathi esisodwa iziqaphi ezimbalwa ku-PC yakhe ngesikhathi esisodwa. Ngaphezu kwalokho, lesi sikhombimsebenzisi siyakwazi ukusekela ukudluliswa kwezithombe ezinokulungiswa okuphezulu (4K), kanye namafayela wevidiyo ngefomethi ye-3D. Kuyaqapheleka ukuthi i-DP iza ngamasayizi amabili – ejwayelekile kanye ne-mini. Uhlelo lokuxhuma ikhompuyutha, ikhompuyutha ephathekayo kumamonitha, i-TV, noma enye ividiyo, impahla yomsindo iyafana nalapho usebenzisa izintambo ezijwayelekile ze-HDMI. Udinga nje ukuxhuma idivayisi eyodwa kwenye usebenzisa intambo ye-DP. Uma imonitha yakho noma i-TV ingenaso lesi sixhumi,
Nge-DP kukhompyutha, ungakwazi ukuxhuma amamonitha amabili ahlukene ochungechungeni. Ukuze wenze lokhu, udinga ukwenza isiqiniseko sokuthi ikhadi levidiyo elifakwe ku-PC lisekela i-DP, futhi umqaphi uyahambisana nomsebenzi wokudlulisa idatha okusakazwa okuningi (MST DisplayPort). Khona-ke ukuqapha kokuqala kufanele kuxhunywe ngekhebula ku-DisplayPort, etholakala ku-PC. Okuphumayo kwe-DP kwemonitha yokuqala bese kuxhunywa ngentambo kokokufaka kwe-DisplayPort kwemonitha yesibili. Eqapheni lokuqala, udinga ukwenza kusebenze imodi ye-DisplayPort, kanti kowesibili, okokugcina ochungechungeni lokuxhuma, udinga ukuyivala ngokuphambene nalokho. Uma kuqhathaniswa nezinye i-interface, i-DisplayPort isanda kuqala ukuthola ukuthandwa phakathi kwabasebenzisi. Manje isisetshenziswa kakhulu ukuxhuma ama-PC esimanje, athuthukile kumamodeli amasha wokuqapha afakwe i-DP. Kuyaqapheleka ukuthi abakhiqizi bamakhadi wevidiyo bahlomisa iningi lemikhiqizo yabo, eyingxenye yamamodeli aphambili, ngalesi sikhombimsebenzisi. Ngaphezu kwalokho, leli chweba lisetshenziswa ngenkuthalo ezimweni lapho kudingekile ukufaka ithiyetha yasekhaya. Ngokusho kwabanye ochwepheshe, ubuchwepheshe be-DisplayPort bungase bube namandla esikhathini esizayo ngenxa yokuthandwa nokusetshenziswa kwezinga lokudlulisa izithombe le-8K.
