- Ubude obude bekhebula nekhwalithi yokudlulisela;
- Isixazululo esikhulu esisekelwa ngokuqukethwe okudlulisiwe.
Izinhlobo ze-HDIMI zokuxhuma
Isixhumanisi se-HDMI sinamaxhumana nabo angu-19 okudluliswa kwesithombe futhi sikhiqizwa ngezici ezine ezahlukene:
- Thayipha i-A ukuhluka okuthandwa kakhulu kwalesi sixhumano, esetshenziselwa cishe wonke amakhompyutha, amathelevishini, abaqaphi, ama-laptops. Inketho enkulu kakhulu;
- Thayipha C - inguqulo encishisiwe, evame ukusetshenziselwa ezincwadini ze-netbooks nezinye izinhlobo ze-laptops namathebulethi;
- Thayipha i-D inguqulo encane kakhulu yesikhombisi esetshenziselwa ubuchwepheshe obuncane obuphathekayo - ama-smartphone, amaphilisi, ama-PDA;
- Uhlobo E lenzelwe kuphela izimoto, likuvumela ukuba uxhume noma iyiphi idivayisi ephathekayo kukhompyutha yebhodi. Unokuvikeleka okukhethekile ngokushintsha kwezinga lokushisa, ukucindezela, umswakama nokudlidliza okukhiqizwa injini.
Izinhlobo zezixhumi ze-DisplayPort
Ngokungafani nomxhuma we-HDMI, i-DisplayPort inokuxhumana okukodwa - oxhumana nabo abangu-20 kuphela. Noma kunjalo, inani lezinhlobo nezinhlobo zezixhumi kuncane, kodwa ukuhluka okukhona kuyashintsha kakhulu kwezobuchwepheshe obuhlukile be-digital, ngokungafani nomncintiswano. Lezi zinhlobo zezixhumi ziyatholakala namuhla:
- I-DisplayPort - isixhumi esiphezulu, ifika kumakhompyutha, ama-laptops, amathelevishini. Kufana nehlobo le-HDMI A;
- I-Mini DisplayPort yinguqulo encane ye-port, engatholakala kwezinye i-laptops ezinama-compact, amaphilisi. Izici zobuchwepheshe zifana kakhulu nomxhumanisi wohlobo C we-HDMI
Ngokungafani namapayipi e-HDMI, i-DisplayPort inesici esikhishiwe sokuvimbela. Naphezu kokuthi abathuthukisi be-DisplayPort abazange bacacise ngesitifiketi somkhiqizo wabo iphuzu ngokufaka ukukhiya njengento evumelekile, abakhiqizi abaningi basakhipha imishini yokudoba. Noma kunjalo, kwi-Mini DisplayPort kuphela abakhiqizi abambalwa bafake i-cap (ngokuvamile, ukufaka le ndlela kumxhumanisi onjalo akuvunyelwe).
Amakhodi we-HDMI
Izintambo zokugcina ezinkulu zokuvuselela zalesi sixhumano zamukelwe ekupheleni kuka-2010, ngenxa yokuthi ezinye izinkinga zamafayela alalelwayo namavidiyo zizinzile. Izitolo azisezidayise izintambo zesikhathi esidala, kodwa ngenxa yokuthi Ama-HDMI amachweba ajwayelekile kunawo wonke emhlabeni, abanye abasebenzisi bangase babe nezintambo eziningana ezidlule isikhathi esingeke bakwazi ukuhlukanisa kusuka ezisha, ezingabangela ubunzima obengeziwe.
Lezi zinhlobo zamakholi ezixhumi ze-HDMI ezisetshenziswayo okwamanje:
- I-HDMI Standard iyindlela evamile kakhulu futhi eyisisekelo yekhebula elingase isekele ukuhanjiswa kwevidiyo ngesinqumo esingaphezu kuka 720p no-1080i;
- I-HDMI Standard ne-Ethernet yikhebula elifanayo ngokuqondene nezici njengeyaphambilini, kodwa ukusekela ubuchwepheshe be-intanethi;
- I-HDMI ephezulu kakhulu-lolu hlobo lwekhebula lungcono kakhulu kulabo abasebenza ngokusebenza ngehluzo noma bathanda ukubukela amabhayisikobho / ukudlala imidlalo ku-Ultra HD isinqumo (4096 × 2160). Noma kunjalo, ukwesekwa kwe-Ultra HD yale divayisi kuyiphutha, okwenza ividiyo idlale imvamisa kuze kube yi-24 Hz, okwanele ukubukwa kwamavidiyo akhululekile, kodwa izinga legeyimu lizoba mpofu kakhulu;
- I-HDMI ne-Ethernet ephezulu kakhulu ifana ne-analog esivela esigabeni esandulele, kodwa futhi inezela ukwesekwa kwevidiyo ye-3D ne-intanethi.
Zonke izintambo zinomsebenzi okhethekile - i-ARC, evumela umsindo wokudlulisela kanye nevidiyo. Ezinhlobonhlobo zanamuhla zezintambo ze-HDMI, kukhona ukusekelwa kobuchwepheshe be-ARC egcwele, ngenxa yokuthi umsindo nevidiyo kungadluliselwa ngekhebula elilodwa ngaphandle kwesidingo samafelethi angeziwe.
Noma kunjalo, lobu buchwepheshe abusebenziswanga kakhulu emakhompheni endala. Ungabuka ividiyo futhi ngesikhathi esifanayo uzwe umsindo, kodwa ikhwalithi yayo ngeke ihlale ihamba phambili (ikakhulu uma uxhuma ikhompyutha / laptop kwi-TV). Ukulungisa le nkinga, kufanele uxhume i-adaptha yomsindo ekhethekile.
Izintambo eziningi zenziwe ngethusi, kodwa ubude babo abudluli ngamamitha angu-20. Ukuze udlulisele ulwazi ngamabanga amade, lawa ma-cable subtypes asetshenziswa:
- I-CAT 5/6 - isetshenziselwa ukudlulisa ulwazi ngaphezu kwebanga lamamitha angu-50. Umehluko ezinguqulo (5 noma 6) awudlali indima ekhethekile kulekhwalithi kanye nebanga lokudluliswa kwedatha;
- Coaxial - ikuvumela ukuba udlulise idatha ngaphezu kwebanga lamamitha angu-90;
- Ama-fibre optic - adingeka ukudlulisa idatha ngaphezu kwebanga lamamitha angu-100 noma ngaphezulu.
Amakhodi we-DisplayPort
Kukhona uhlobo olulodwa kuphela lwekhebula, elino-version 1.2 lwanamuhla. Izici zekhebula ze-DisplayPort ziphakeme kakhulu kune-HDMI. Isibonelo, ikhebula le-DP liyakwazi ukudlulisela ividiyo ngokuxazulula amaphikseli angu-3840x2160 ngaphandle kwezinkinga, ngenkathi ingalahlekelwa izinga lokudlala - lihlala liphelele (okungenani i-60 Hz), futhi isekela ukudluliswa kwevidiyo ye-3D. Noma kunjalo, angase abe nezinkinga ngokudlulisa umsindo, kusukela Awekho i-ARC eyakhelwe ngaphakathi, ngaphezu kwalokho, lezi zinkambo ze-DisplayPort azikwazi ukusekela izixazululo ze-intanethi. Uma udinga ukuhambisa ngesikhathi esifanayo ividiyo nokuqukethwe komsindo ngekhebula elilodwa, kungcono ukhethe i-HDMI, ngoba I-DP kufanele ukhethe ngokungeziwe ukuthenga i-headset ekhethekile yomsindo.
Lezi zingcingo zikwazi ukusebenza ngosizo lwe-adapters ezifanele hhayi kuphela nezixhumanisi ze-DisplayPort, kodwa futhi ne-HDMI, i-VGA, i-DVI. Isibonelo, izintambo ze-HDMI zingasebenza kuphela nge-DVI ngaphandle kwezinkinga, ngakho-ke i-DP iwina umncintiswano wayo ngokuhambisana nezinye izixhumi.
I-DisplayPort inezinhlobo zekhebula ezilandelayo:
- I-Passive Ngalo, ungadlulisela isithombe njengama-pixel angu-3840 × 216, kodwa ukuze yonke into isebenze kuma-maximum frequencies (i-60 Hz ilungile), kubalulekile ukuthi ubude bekhebula lungabi ngaphezu kwamamitha amabili. Amakhodi anebude bamamitha angu-2 kuya ku-15 angadlala kuphela ividiyo ye-1080p ngaphandle kokulahlekelwa ngesilinganiso sehlaka noma 2560 × 1600 ngokulahlekelwa okuncane kwesilinganiso sehlaka (cishe ama-45 Hz angama-60);
- Isebenza. Iyakwazi ukudlulisela amaphuzu angu-2560 × 1600 wevidiyo ngaphezu kwebanga elingamamitha angu-22 ngaphandle kokulahlekelwa kwekhwalithi yokudlala. Kukhona ukuguqulwa okwenziwa nge-fiber optical. Esikhathini salokugcina, ibanga lokudlulisela ngaphandle kokulahlekelwa kwekhwalithi landa ngamamitha angu-100 noma ngaphezulu.
Futhi, izintambo ze-DisplayPort zinebude obujwayelekile kuphela bokusetshenziswa kwekhaya, ezingenakudlula amamitha angu-15. Ukuguqulwa ngohlobo lwama fiber optic, njll. I-DP ayikho, ngakho-ke uma udinga ukudlulisa idatha ngekhebula ngaphezu kwamamitha angaphezu kwamamitha angu-15, kuzodingeka ukuthi uthenge izilinganiso ezikhethekile noma ubuchwepheshe bokuncintisana. Noma kunjalo, izinkambo ze-DisplayPort ziyazuza ngokuhambisana nezinye izixhumanisi futhi njengokudluliselwa kokuqukethwe okubukwayo.
Amathrekhi wokuqukethwe komsindo nevidiyo
Kuleli phuzu, izixhumi ze-HDMI nazo zilahlekelwa, ngoba ayisekeli imodi ye-multi-streak yokuqukethwe kwevidiyo neyomsindo, ngakho-ke, ulwazi lungavela ngaphandle kokuqapha eyodwa. Ngomsebenzisi ovamile, lokhu kuwanele, kodwa kubadlali be-professional, abahleli bevidiyo, abaklami be-graphic ne-3D lokhu kungase kunganele.
I-DisplayPort inenzuzo ehlukile kule ndaba, kusukela Ukukhishwa kwesithombe ku-Ultra HD kungenzeka ngokushesha kulabaqaphi ababili. Uma udinga ukuxhuma abaqaphi abangu-4 noma ngaphezulu, kuzomele uhlehlise ukuxazulula kwakho konke ku-Full noma nje i-HD. Futhi, umsindo uzoboniswa ngokwahlukana ngamunye kwabaqaphi.
Uma usebenza ngokusebenza ngamahluzo, ividiyo, izinto ze-3D, imidlalo noma izibalo, unake ama-computer / i-laptops nge-DisplayPort. Kungcono nakakhulu, uthenge idivayisi enezixhumi ezimbili ngesikhathi esisodwa - i-DP ne-HDMI. Uma ungumsebenzisi ovamile ongadingi lutho oluthe xaxa olusuka kukhompyutha, ungamisa imodeli nge-HDMI port (lawo madivaysi ngokuvamile ayabiza kancane).
