Yintoni uqhagamshelwano lwetshiphu emsebenzi

Ngesibizo «uqhagamshelwano lwetshiphu emsebenzi output" ngokuyimfuneko lifumana wonke umntu wagqiba ukuthenga TV elisetyenziswayo lomqhubekisi phambili okanye esweni. Intuthuko kwezobuchwepheshe yedijithali olukhula ngokukhawuleza, leyo ngaphambili umntu kunzima ukucinga. Kwanele ukuba ukukhumbula endala iziseko eriyali RF (iziseko) e balwamkele TV, ebezikho ingatshintshanga amashumi eminyaka. Ukuze siphendule lo mbuzo, "Yintoni na uqhagamshelwano lwetshiphu emsebenzi?», Khumbula imbali uphuhliso lwemigangatho.

Nokufika iiphaneli umabonakude wedijithali kunye ividiyo kunye nokugqama, kwacaca ukuba indlela analog yokusasazela uphawu ngokwalo phantse ndidiniwe. Ngenxa yoko, oko saphuhliswa ze safezekiswa DVI. Kulula kakhulu ukuba ukusebenzisa, yaye umsebenzi transmission ividiyo ukumelana ngokupheleleyo. Nangona kunjalo, iye ezinye iingxaki xa - ukudlulisa isandi (ngakumbi kule kamva), akukho nako ukukhusela umxholo ukuva ukukopa, akunamsebenzi ukuphumeza iimpawu ezongezelelweyo. Ukusombulula ezi ngxaki ziye ecetywayo imigangatho ezininzi - uqhagamshelwano lwetshiphu emsebenzi, Bonisa Port, kunye nabanye. Makhe sibone oko uqhagamshelwano lwetshiphu emsebenzi.

Igama elithi «lwetshiphu» yi acronym sakhiwa oonobumba bokuqala amagama High Definition semalthimidiya esikumgangatho ophezulu (semalthimidiya esikumgangatho ophezulu nokusombulula Isinxulumaniso). Uqhagamshelwano lwetshiphu emsebenzi ujongano ikuvumela ukuba ukusika data kumajelo enkcazelo omnye multicore cable evela Sombhalo, idikhowuda, ividiyo okanye omnye umthombo ukuya TV. Ngenxa yoko akukho ucinezelo uphawu, okanye nayiphi na enye ingxoxo zenziwe. Enyanisweni, kukho transfer of "mzobo-nani." Okwangoku, eli zibuko uqhagamshelwano lwetshiphu emsebenzi isetyenziswa yi video and audio izixhobo ezininzi. Advertising uthi ukuba oku lolusezantsi elizayo.

Nabani na onomdla koko lwetshiphu, ngokuqinisekileyo uyazi ukuba esibonakalayo ekuvumela ukuba usebenze njenge eqhelekileyo isignali yevidiyo yedijithali, kwaye nokuqukuqela lwezigqibo ukuya 1080p (HDTV). Ngaphezu koko, eqala version 1.3 (2006) wazisa inkxaso-bit 48 umbala, umsebenzi ochanekileyo yazalisekiswa format Dolby HD yaye ekugqibeleni iyasebenza indlela oluzenzekelayo ukuba sync imisinga ezirekhodiweyo neevidiyo. Wesibili kuyimfuneko kuba ixesha ukucazulula ulandelelwano wevidiyo phantse lonk obungaphezu kokulibazisa isandi. Ukuvumelanisa kwenza lo mahluko ayibonakali kumsebenzisi ekupheleni.

Osuka version 1.3 (enyanisweni, Kuyinto nqanaba) imbonakalo bandwidth iphakanyiswe phantse ndineSibini usiphinda - ukusuka 4,95 ukuya 10.2 Gbps. Oku kuphunyezwe ngokwandiswa rhoqo clock ukusuka endala MHz 165 ukuya 340 MHz. Phela, oko umdla DVI bandwidth kukuthi "kuphela" 3.4 Gbps. Nangona oku kwanele ukuba le vidiyo, kodwa ikamva kuphela uqhagamshelwano lwetshiphu emsebenzi okanye nezisombululo ezifanayo. Kwanele ukuba bathi uguqulelo 1.4 (2009) wazisa inkxaso isisombululo 4096h2160, ukuza kuthi ga kwi-24 Hz nditshayele.

Enye yezona iinkalo uqhagamshelwano lwetshiphu emsebenzi - ukukwazi transfer asibhozo-channel yedijithali isandi ezineempawu of 24-bit 192 kHz. Kumalunga DTS HD, DTS, Dolby Digital, Dolby TrueHD, yaye ke, i-stereo ukungafi.

Kutshanje, (funda: iinguqulelo ezintsha) yinxalenye umgangatho uqhagamshelwano lwetshiphu emsebenzi waye indlela nokhuseleko ukukopisha isiqulatho ezosulela - HDCP. Xa udlala copyright-ekhuselweyo lo bugcisa multimedia izixhobo umlambo kwananwe iqhosha-idikhowuda. Naluphi na utshintsho eliphakathi uvalela transmission isitshixo kwaye kwenza kube nzima ukuba badlale. Inethiwekhi ulwazi oluninzi malunga ngokuqhekezwa kule yokhuseleko, kodwa kude HDCP ayikho kakhulu isoloko isetyenziswa, okoko nje kukho ezinye imithombo lasemaphandleni umxholo.

Ngokucacileyo, le umba we "Yintoni uqhagamshelwano lwetshiphu emsebenzi?» Akukho nto ingakumbi ezintsonkothileyo okanye bengasiqondi. Kuba umsebenzisi isiphelo iluncedo ukuba isinxibelelanisi Ngokomzi (abafowunelwa-19 okanye 29) kwaye ikuvumela ukuba okudlulisela isandi ukusuka 3D ividiyo, ngenxa ekwiqondo eliphezulu, unako ukusebenza kunye HDTV kwi multi-esweni uqwalaselo. Kwezinye iimeko, le DVI njengesiqhelo ayikho ngaphantsi uqhagamshelwano lwetshiphu emsebenzi. Ubuncinane ngokuba ngoku ...
