Lapho i-DVD isungulwa ngonyaka ka 1996/1997, kwaba ngcono kakhulu kusuka ku-VHS. Ngenxa yalokho, i-DVD yaba umkhiqizo wevidiyo ophumelele kakhulu emlandweni. Kodwa-ke, lapho i-HDTV isungulwa, amafomu amabili atholakale kubathengi ngo-2006 okwakhulisa ibha phezulu: i- HD-DVD ne-Blu-ray .
I-Blu-ray vs i-DVD
Umehluko oyinhloko phakathi kwe-DVD ne-Blu-ray / HD-DVD ukuthi i-DVD iyifomethi yokuchaza ejwayelekile lapho ulwazi lwama disc lukhokhwa ngesixazululo sama-480i , ngenkathi ulwazi lwe-Blu-ray / HD-DVD lwama disc lungabhalwa ku- 1080p . Lokhu kusho ukuthi i-Blu-ray / i-HD-DVD yayinamandla okusebenzisa ikhwalithi yesithombe se-HDTV.
Kodwa-ke, nakuba i-Blu-ray ne-HD-DVD ifinyelele imiphumela efanayo, indlela abayisebenzisayo ngayo yayihlukile, okwenza ibe namafomethi angahambisani (khumbula iVHS vs BETA). Yiqiniso, lokhu kuholele "impi yokufometha" lapho ama-studio e-movie ayefanele akhethe ukuthi iyiphi ifomethi yokukhulula ama-movie kuwo, futhi abathengi kwakudingeka bavote nge-dollar yabo ukuze banqume ukuthi yibaphi abadlali abazokuthenga. Umphumela - ngo-2008 i-HD-DVD yavalwa ngokusemthethweni, ibeka i-Blu-ray ngokuthi "inkosi yegquma" njenge-disc-definition disc eyahlukile ku-DVD.
Uma ungazange uqhubekele ku-Blu-ray okwamanje, okulandelayo izinto eziyinhloko okudingeka wazi.
I-Blu-ray Discs
Inhloso eyinhloko ye-Blu-ray Disc player yiqiniso ukuthi idlale ama-Blu-ray Discs, futhi kuneziqu ezingaphezu kuka-100,000 ezitholakalayo, ezikhishwe yizo zonke izikhulu ezinkulu nezinkampani ezincane kakhulu. Abadlali abaningi bangadlala kokubili i-2D ne-3D Blu-ray Discs (i- 3D TV noma iprojekti yevidiyo ye-3D edingekayo ).
Amanani wezinhlamvu ze-Blu-ray ngokuvamile asebenzisa ama-$ 5-noma- $ 10 ngaphezulu kwama-DVD. Noma kunjalo, iziqu ezindala ze-Blu-ray Disc ngezinye izikhathi zingatholakali zenani eliphansi kunezinye izihloko zeDVD ezintsha. Amaphakheji amaningi we-Blu-ray Disc abuye ne-DVD version ye-movie (noma i-TV show).
Isidlali se-Blu-ray Disc Ukungafani
Ngaphezu kokudlala i-Blu-ray Discs, laba badlali baye bavela ekufinyeleleni okuphelele kokuqukethwe kanye nesistimu yokudlala.
Bonke abadlali be-Blu-ray Disc (ngaphandle kwamanye amamodeli asekuqaleni) nabo badlala ama-DVD nama-CD. Ukuze uthole ukuguquguquka okungeziwe, abadlali abaningi bangafinyelela nokuqukethwe komsindo / ividiyo okusakazwa kusuka ku-intanethi (okungabandakanya i-Netflix, i-Vudu, i-Hulu, njll ...) noma inethiwekhi yasendaweni yasendaweni (ama-PC / amaseva wemidiya), nokuqukethwe okugcinwe kumadivayisi e-USB ahambisanayo , njenge-flash drives.
Ukufinyelela okwengeziwe kokufinyelela nokuphathwa kokuqukethwe okuhlinzekwa ngabanye abadlali be-Blu-ray Disc kufaka Screen Mirroring (Miracast) , okuvumela ukukwabelana ngokuqukethwe komsindo / ividiyo kusuka e-smartphone ehambisanayo nethebhulethi, okusho ukuthi, ngokufanayo i-audio nevidiyo ku-TV ehambisanayo uhlelo lokulalelwayo, kanye ne-CD-to-USB Ripping, okuthi, njengegama eliwela, likuvumela ukukopisha umculo kusuka ku-CD kuya ku-USB flash drive.
I-DVD yakho yamanje ayikho Isisetshenziswa Uma Ushintshela ku-Blu-ray
Njengoba kushiwo esigabeni esandulele i-Blu-ray Disc Players nayo idlala ama-DVD, okusho ukuthi awudingi ukukhipha iqoqo lakho le-DVD futhi, empeleni, ama-DVD angabheka kangcono uma edlalwa kumdlali we-Blu-ray Disc ngoba bonke abadlali ube nevidiyo ye-upscaling . Lokhu kunikeza umlinganiso osondelene phakathi kwesinqumo ukufundwa i-DVD kanye nokuveza okubonakalayo ukuveza amandla we-HDTV noma i-HD Video projector. Nakuba angeke wenze ama-DVD akho abukeke njengama-Blu-ray wangempela amaDiski (akukho lutho olushintshwa ngokomzimba kwi-DVD), nakanjani kuthuthukiswa ngaphezu kwezinga elijwayelekile lokudlala i-DVD.
Yazi izinhlobo zoxhumo Abadlali be-Blu-ray Disc Have
Lapho beqala ukuphuma ngo-2006/2007, abadlali be-Blu-ray Disc banikeza izinketho zokuxhumanisa ezazijwayele abanikazi be-DVD abadlali, okubandakanya okunye, noma okunye okulandelayo: Imiphumela ehlanganisiwe, i-S-Video, neyengxenye yevidiyo, i-Analog Stereo , I-Digital Optical, kanye / noma i-Digital Coaxial Audio imiphumela. Noma kunjalo, ukuhlangabezana nezidingo ze-High Definition resolution output output (kufika ku-1080p), imiphumela ye-HDMI ifakiwe.
Futhi, kuma-Blu-ray disc abaphezulu be-Blu-ray disk 5.1 / 7.1 iziphumo zesimanje zesiteshi esithumela isignali yomsindo ozungezile abamukeli be-AV ababenezimpendulo ze-analog 5.1 / 7.1, ngezinye izikhathi zifakiwe.
Noma kunjalo, kukhona okuningi. Bonke abadlali (ngaphandle kwamanye amamodeli asekuqaleni) nabo banamaphakheji e-Ethernet / LAN okuxhumeke ohlangothini lwenethiwekhi yasendaweni kanye ne-intanethi ( abadlali abaningi nabo bane-WiFi eyakhelwe ngaphakathi ), futhi abadlali be-Blu-ray Disc ngokuvamile banesisodwa noma ezimbili ze-USB amarekhodi angasetshenziswa ukulayisha izibuyekezo ze-firmware , kanye / noma ukuhlinzekela okukodwa noma okungaphezulu kwalokhu okulandelayo: Ukwandiswa kwememori ye-BD-Live (enikeza ukufinyelela kokuqukethwe okusekelwe ku-intanethi okuhlobene nezihloko ezithile ze-Blu-ray Disc), ukufinyelela kumafayela womidijithali wedijithali agcinwe kuma-flash drive, noma ahlinzeke ukuxhumeka kwe-adapter ye-WiFi ye-USB yabadlali abangenayo i-WiFi eyakhelwe kakade.
Ukuxhumeka kwe-Blu-ray ne-Isinqumo sika-2013
Ngokuphathelene nokuxhumana, kwenziwa isinqumo sokuthi zonke izixhumanisi zevidiyo ze-analog zisuswe kubadlali be-Blu-ray Disc eziqhubeka phambili kusukela ngo-2013. Futhi, nakuba kungadingeki, abanye abakhiqizi baye bakhetha nokususa uxhumano lwe-analog audio.
Lokhu kusho ukuthi wonke ama-Blu-ray Disc abadlali okwamanje bathengiswa amasha kuphela aneziphumo ze-HDMI zokukhishwa kwevidiyo, nokulalelwayo, i-HDMI kanye nokukhishwa kwe-Digital Optical kanye / noma i-Digital Coaxial. Futhi, abanye abadlali banemiphumela emibili ye-HDMI esetshenziselwa lapho amavidyo namavidiyo adinga ukuthunyelwa ezindaweni ezihlukene.
Ukuhluka okungeziwe kuphela ukuthi abanye abadlali abaphezulu be-Blu-ray Disc banikeza isethi yemiphumela yomsindo we-analog wesiteshi 5.1 / 7.1 yokusetshenziswa kanye nabamkeli bemidlalo yaseshashalazini be-analog kuphela noma ama-amplifiers.
Ukwenza ikhodi yesifunda kanye nokuvikelwa kokukopisha
Ngokufanayo ne-DVD, ifomethi ye-Blu-ray Disc nayo inesimiso sokubhala ikhodi nokukopisha ikhophi . Lokhu kusho ukuthi abadlali abathengiswa ezindaweni ezithile zomhlaba bahambisana nekhodi ethile yesifunda - Nokho, ngokungafani neDVD, kunezifunda ezimbalwa kanye nama-Blu-ray amaningi ama-disc, empeleni, akuzona izigcawu zesigodi njalo.
Ngakolunye uhlangothi, ifomethi ye-Blu-ray Disc nayo isekela ukuvikela ikhophi ethuthukisiwe ngezindlela ezimbili. Okokuqala, izinga le-HDMI ludinga ukuthi amadivaysi anikwe amandla we-HDMI akwazi ukubonana amadivaysi avikelwe nge-"Process Handshake Process". Uma ukuxhashazwa kwesandla kungenzeki, akukho mshini wesidlali se-Blu-ray Disc kuya kwi-HDMI ene-TV noma iVidiyo yevidiyo ezoboniswa. Noma kunjalo, "inqubo yokubamba ngesandla" ngezinye izikhathi ine-alamu yamanga, engadinga ukuxazulula izinkinga ukulungisa.
Enye izinga lokukopisha-ukuvikelwa, okuklanyelwe ngqo i-Blu-ray yiCinavia. Ukukhokhiswa kwe-Cinavia kuvimbela ukudlala kwamakhophi angagunyaziwe okuqukethwe kokuqukethwe kwe-Blu-ray Disc. Bonke abadlali be-Blu-ray disc eyenziwe eminyakeni yamuva yokusatshalaliswa kwe-US, futhi iningi elenzelwe ukusatshalaliswa kwamanye izimakethe, kuyadingeka ukuthi libe amandla aseCinavia.
Udinga i-HDTV ukuthola ama-Visual Benefits of Blu-ray
Lapho ziqala, abaningi abadlali be-Blu-ray Disc bangakwazi ukuxhumeka ku-TV okungenani okungenayo imibono yevidiyo. Kodwa-ke, indlela kuphela yokufinyelela ekucacisweni okuphezulu okuphezulu kwe-Blu-ray isinqumo (1080p) ngokuxhumeka kwe-HDMI, noma kubadlali abenziwe ngaphambi kuka-2013, neminye imikhawulo, ukuxhumeka kwevidyo yevidyo.
I-Blu-ray ayikho nje ukuthuthukiswa kwevidiyo
Ngaphezu kwevidiyo yekhwalithi ye-1080p, abadlali be-Blu-ray Disc bangafinyelela amafomethi engeziwe alalelwayo angabhaliswa kuma-Blu-ray Discs (kodwa hhayi kwiDVD), njenge- Dolby TrueHD , i- Dolby Atmos , i- DTS-HD Master Audio , ne- DTS: X , futhi mhlawumbe ukhethe ngaphakathi (uma kwenzeka ku-Dolby TrueHD / DTS HD-Master Audio) noma udlulisele lokho, ne-Dolby Atmos / DTS: X, engafakiwe kwi-home receiver reception ye-decoding. Uma umamukeli wakho engahambisani nalezi zakhiwo, ungakhathazeki, umdlali uzothola ngokuzenzakalelayo lokhu futhi azenzeke kuDolby Digital / DTS ejwayelekile
I-Factory ye-4K
Ngenxa yokungeniswa kwe- 4K Ultra HD TV , umqondo we-Blu-ray Disc player uye waqhubeka ngokuqhubekayo ukuze uhlangabezane nenselele. Kusukela ngo-2012/2013, abadlali be-Blu-ray Disc abanekhono lokwenza u- 4K Upscaling bavele, ngokukhetha okuhle manje kuyatholakala.
Lokhu kusho ukuthi uma unayo i-4K Ultra HD TV, ungathenga isidlali se-Blu-ray disc esinamandla okubuka okuqukethwe kwe-Blu-ray Disc (ne-DVD) ye-upscale ukuze ibukeke kangcono ku-4K Ultra HD TV. Njengoba nje i-DVD upscaling ingefani ne-high-definition definition yangempela (1080p), ukuphakama okungu-4K akukhipha imiphumela efanayo ebonakalayo njenge-4K yeqiniso, kodwa isondela, futhi empeleni, kubathengi abaningi, abasondelene ngokwanele.
Noma kunjalo, indaba ka-4K ayipheli lapho. Ngo-2016, ifomethi entsha yeDiski yenziwa itholakale kubathengi: i- Ultra HD Blu-ray . Le fomethi isebenzisa ama-discs abukeka kwangaphandle njenge-Blu-ray Disc, kodwa ulwazi lwevidiyo lukhokhwe kwisinqumo se-4K sangempela (nomunye umbala owengeziwe nokuthuthukiswa kwe- HDR / ukukhathanisa okuhlukile ) okungasebenzisa amandla okugcwele we-4K Ultra HD TV ehambisanayo .
Yebo, lokhu kusho ukujikeleza okusha kwabadlali nama-discs - kodwa, ungesabi, nakuba ngeke ukwazi ukudlala ama-disk ama-Blu-ray amafomethi we-Blu-ray kumanje abadlali be-Blu-ray Disc, abadlali abasha bayakwazi ukudlala ama-Blu-ray Discs wamanje (2D / 3D), ama-DVD, (nge-4K upscaling kokubili ama-Blu-ray Discs nama-DVD) nomculo womculo. Abadlali abaningi nabo bahlanganisa uxhumano lwenethiwekhi yokufinyelela okuqukethwe kokusakazwa kwe-intanethi ( kufaka okuqukethwe okukhipha okungu-4K ), nokuqukethwe okutholakala kwamanye amadivaysi ahambisanayo angase abe yingxenye yenethiwekhi yakho yasekhaya.
Yazi ukuthi Ukungena Kanjani Ku-Blu-ray Kuzokubiza
Abadlali be-Blu-ray baqala ngezinga eliphansi njenge $ 79 futhi bafinyelela ku-$ 1,000. Ukuze uthole imali engu-$ 99, ungathola ngempela umdlali ohloniphekile, kodwa njengoba ukhuphuka ngentengo, izinketho zokuxhumeka ezengeziwe, ukucubungula kwevidiyo okungcono, ukuxhumana okunzulu ngokwengeziwe, nokunye okukhethwa kukho kokusakaza kwe-intanethi kunikezwa ngokujwayelekile.
Njengoba ungena kumaphuzu amanani aphezulu, ukudlala komsindo we-analog kugcizelelwe kulabo abasebenzisa isidlali sabo se-Blu-ray ukuze kube nomculo ojulile olalele kumaCD, kanye namafomethi e-audiophile- target SACD ne-DVD-Audio.
Kodwa-ke, ngisho nabadlali be-Blu-ray Disc abanamanani aphansi abanikeza ukudlala kwe-3D lapho bexhunywe ku-3D TV ne-4K Upscaling uma bexhunywe ku-4K Ultra HD TV.
Mayelana nabadlali be-Ultra HD Bu-ray Disc, bangatholakala ku-$ 199 kuya ku-$ 1,500, okuyinto, nakuba ibiza kakhulu kunezingcingo eziningi ze-Blu-ray disc, vele ukhumbule emuva ngo-2006/2007 lapho abadlali be-Blu-ray Disc kuthengiswa ngo-$ 1,000 ububanzi bamanani, futhi abadlali bokuqala be-DVD abaqalisiwe ngo-1996/1997 babenani lika-$ 500 lamanani entengo.
