Uyini-HDMI

Ethemini «-HDMI okukhipha" ngempela sihlangana wonke umuntu banquma ukuthenga TV yesimanje noma ukuqapha. Intuthuko kwezobuchwepheshe digital ithuthuka ngokushesha, okuyinto ekuqaleni wawungeke nokuyicabanga. Engingakusho nje kokukhumbula ubudala antenna RF enethiwekhi (enethiwekhi) e abamukelayo TV, okuyinto ikhona ingashintshiwe amashumi eminyaka. Ukuze siphendule lo mbuzo, "Kuyini-HDMI?», Khumbula umlando ukuthuthukiswa kwamazinga.

Njengoba sekunama-digital ithelevishini panel kanye nokuqukethwe video nge lesinqumo high, kwaba sobala ukuthi indlela analog yokudlulisela isignali ngokwalo cishe sikhathele siyingcuba. Ngenxa yalokho, yayilokhu lwenteke DVI esibonakalayo. Kulula ukusebenzisa, nevidiyo yokudlulisela umsebenzi ukubhekana ngokugcwele. Nokho, it has ezithile ezingathandeki - hhayi Ukudlulisa umsindo (okwengeziwe lokhu kamuva), akakwazi ukuvikela okuqukethwe ngocansi kusukela ukukopisha, ke akusho liqalise izici ezengeziwe. Ukuze kuxazululwe lezi zinkinga okuphakanyiswe amazinga eziningana - HDMI, yembobo yokubonisa, nabanye. Cabanga ngalokho yocezuningi.

Igama elithi «-HDMI» kuyinto emelela sakhiwa izinhlamvu zokuqala amagama soxhumanoningi oluchazayo (soxhumanoningi oluchazayo nge ephezulu definition isixazululo). -HDMI interface kwenza kube kungenzeka ukuba adlulisele umfudlana digital imininingo soxhumanoningi komunye multicore ikhebula Sombhalo, a isiqophi semithombo, ikhadi isiqophi noma omunye umthombo ku-TV. Ngakho akukho kokucindezelwa isignali, noma yimuphi omunye ukuguqulwa hhayi lwenziwa. Eqinisweni, kukhona ukudluliselwa "sibalo-oneso elibukhali." Okwamanje, ye-HDMI isetshenziswa ividyo ne-odiyo kumadivayisi amaningi. Ukukhangisa uthi lena ejwayelekile esizayo.

Noma ubani onesithakazelo lokho yocezuningi, ngokuqinisekile uyazi ukuthi esibonakalayo likuvumela ukuba sizosebenza njengothisha ezivamile digital Isignali yevidiyo, futhi ukugeleza izinqumo kuze kube 1080p (HDTV). Ngaphezu kwalokho, kusukela enguqulweni 1.3 (2006) wethula usekelo umbala 48-bit, operation lesifanele luyasetshenziswa ngefomethi Dolby HD futhi ekugcineni isebenze ngendlela okuzenzakalelayo ukuze uvumelanise ukusakaza alalelwayo video. Lesi sakamuva kwakudingekile ngoba isikhathi ukuqopha ukulandelana isiqophi cishe njalo mkhulu kunezinhliziyo ukubambezeleka ngenxa umsindo. Ukuvumelanisa kwenza lo mehluko ayibonakali umsebenzisi sekupheleni.

Kuzoqalwa nge-version 1.3 (eqinisweni, kuba soshintsho) esibonakalayo-bandwidth seluphakanyiswe cishe amabili izikhathi - kusuka 4.95 kuya 10.2 Gbps. Lokhu kwenziwa ngokuba okwandisa imvamisa iwashi kusukela elidala 165 MHz ukuze 340 MHz. Phela, kuyathakazelisa ukuthi DVI komkhawulokudonsa kuyinto "kuphela" Gbps 3.4. Nakuba lokhu kwanele zevidiyo, kodwa esikhathini esizayo-HDMI noma izixazululo efanayo ungakwazi kuphela. Engingakusho nje ukuthi inguqulo 1.4 (2009) wethula ukweseka isinqumo 4096h2160, kuze kube manje at 24 Hz shanela.

Esinye sezici-HDMI - ikhono ukudlulisa nesishiyagalombili isiteshi umsindo digital nge izici-24-bit 192 kHz. Kumayelana DTS HD, DTS, Dolby Digital, Dolby TrueHD, futhi yebo, stereo ongafi.

Muva nje, (funda: izinguqulo ezintsha) ingxenye yocezuningi standard kwaba inqubo isivikelo ukukopisha okuqukethwe ngocansi - HDCP. Uma udlala enamalungelo avikelwe lokhu ubuchwepheshe multimedia amadivayisi ekusakazeni benana ukhiye-isiqophi semithombo. Noma yimuphi inkinobho Lesisemkhatsini ikhiye ukudluliswa ukhiye bese kukwenza kungenzeki ukudlala. Inethiwekhi has a lot of ulwazi breaking lokhu kuvikela, kodwa kuze kube se-HDCP akuyona ezivame ukusetshenziselwa, inqobo nje uma kukhona eminye imithombo eminingi okuqukethwe okungavikelwe.

Ngokusobala, impikiswano "Kuyini-HDMI?» Akukho lutho eziyinkimbinkimbi ikakhulukazi noma engaqondakali. Ukuze umsebenzisi ekupheleni kulungile ukuthi izixhumi kuyinto compact (19 noma 29 oxhumana nabo) futhi ikuvumela ukuba udlulise umsindo wokuqukethwe 3D, ngenxa bandwidth okusezingeni eliphezulu, ungasebenza ne-HDTV ekucushweni multi-qapha. Kwezinye izimo, le DVI evamile akuyona kunabayeni yocezuningi. Okungenani okwamanje ...
