Konke okudingeka ukwazi nge-Blu-ray
I-Blu-ray ingenye yefomathi ezimbili ezinkulu eziphezulu zeDesk Definition (enye enye i-HD-DVD) eyathunyelwa kubathengi ngo-2006. Inhloso yayiwukufaka esikhundleni se-standard standard ye-DVD emakethe yase-US naseMhlabeni. Kodwa-ke, ngo- Febhuwari 19, 2008 i-HD-DVD yavalwa futhi manje i-Blu-ray iyona kuphela ifomethi ephezulu ye-disk esekelwe ukusetshenziswa, ne-DVD isasebenza futhi.
I-Blu-ray vs i-DVD
I-Blu-ray ikha isisekelo esungulwe yi-DVD ekufuneni izinga eliphezulu lokubukwa kwe-TV nokulalela. Nakuba i-DVD inikeza isipiliyoni esihle sokubuka, akuyona ifomethi ephezulu yokuchaza. Ngokufika kokubili kwe-HDTV kanye nomkhuba wokubukwa kwe-TV ekhudlwana, nokusetshenziswa kakhudlwana kwamavidyo wevidyo, ukulinganiselwa kwekhwalithi ye-DVD kubonakala kakhulu.
I-Blu-ray yenza umthengi ukuthi abone ukujula okubanzi, ububanzi obuningi be-shades ombala, nemininingwane eminingi esithombeni kunokuba avela ku-DVD, enikeza isipiliyoni esibukwayo sokubuka i-TV esiphezulu esivela kokuqukethwe okubhalwe ngaphambilini esisekelwe kwi-disc esekelwe we-DVD.
Lapho i-DVD isebenzisa ubuchwepheshe be-Red Laser, ifomethi ye-Blu-ray Disc isebenzisa ubuchwepheshe be-Blue Laser nokuxilongwa kwevidiyo eyinkimbinkimbi ukuze kutholakale ukudlala kwevidiyo encazelo ephezulu kwi-disc yesayizi njenge-DVD evamile.
Ukubaluleka kobuchwepheshe be-laser bluhlaza ukuthi i-laser eluhlaza okwesibhakabhaka incane kunomshini obomvu, okusho ukuthi ungagxila ngqo kwi-disc surface. Ukusebenzisa lokhu, onjiniyela bakwazi ukwenza "izibhamu" erekini lapho ulwazi lugcinwa khona encane futhi, ngaleyo ndlela, uvumelane "emigodini" engaphezulu kwi-blu-ray disc kunokungena kwiDVD. Ukwandisa inani lemikhosi kudala amandla okugcina ngaphezulu ku-disc, okudingekayo ukuze isikhala esingeziwe sidingeka ukurekhoda ividiyo ecacile ephezulu.
Ngaphandle komthamo owengeziwe wevidiyo, i-Blu-ray iphinde ivumele amandla amaningi alalelwayo kuneDVD. Esikhundleni sokufaka nje i-Standard Dolby Digital ne-DTS yomsindo esaziwayo kwi-DVD (okubizwa ngokuthi "amafomethi alalelwayo" alahlekile ngoba aqinile kakhulu ukuze afane ne-disc disc), i-Blu-ray inamandla ukubamba iziteshi ezingu-8 zomsindo ongaxhunyiwe ngaphandle kwe-movie.
Sibutsetelo ngokucacile kwefomethi ye-Blu-ray Disc
- I-Disc Storage Cap for Pre-okuqoshiwe (BD-ROM) Izinto zokudlala: I- single-layer (25GB) - I-Double-layer (50GB)
- Ikhono lokugcina i-disc lokuqopha ikhaya: I- single-layer (25GB) - Uhlu olulodwa (50GB). Kunezinhlobo ezimbili ze-Blu-ray Discs eziqoshiwe, i-BD-R (i-Blu-ray Disc Record Once), ne-BD-RE (i-Blu-ray Disc Eyabhalwa kabusha).
- Isilinganiso sokudluliswa kwedatha: 36 kuya ku-48 Mbps (i-Megabits ngayinye yesibili) isilinganiso - esingafinyelela kuma-MPS angu-54 - Lokhu kudlula izinga lokudlulisa le-19.3 Mbps elivunyelwe ukuhanjiswa kwe-HDTV. Lokhu kusho ukuthi i-Blu-ray ayisebenzisi kuphela ulwazi oluthe xaxa kuneDVD, kodwa futhi ingaphatha imininingwane eyengeziwe kunezokusakazwa kwethelevishini ye-HDTV.
- Imininingwane yevidiyo: Iyahambisana ne-Encryption MPEG2 ephelele, kanye ne-MPEG4 AVC (futhi iyazi njenge-H.264), ne-VC1 (ngokusekelwe kwefomethi ye-Microsoft WMV (Windows Media Video). Izinqumo ezivela kuma-480i kuya ku-1080p (ku-2D noma ku-3D - Ukuhambisana kwe-3D kwabanye abadlali kwanezelwa ngonyaka ka-2010) kungasetshenziswa ekuqalisweni komkhiqizi wokuqukethwe.
- Imininingwane Yomsindo: Ngu- Dolby Digital kuphela , i- DTS , ne- PCM engaxhunyiwe kuphela okudingekayo kubo bonke abadlali. Amafomethi alalelwayo alandelayo angakhetha - I- Dolby Digital Plus , i- Dolby TrueHD , i- DTS-HD Master Audio . Kodwa-ke, cishe bonke abadlali be-Blu-ray Disc okwenziwe kusukela ngo-2008 bafaka i-Master Audio TrueHD / DTS-HD i-Master Audio ebhodini lokukhipha ikhodi, okukhiphayo okungenakulinganiswa , noma kokubili. Ngaphezu kwalokho, abadlali abaningi be-Blu-ray Disc nabo bahambisana ne- Dolby Atmos ne- DTS: X ukufaka ikhodi ye-audio enomsindo ozungezile.
- Ukuxhumeka komsindo / yevidiyo: I-Blu-ray format isekela ukukhishwa komsindo kusuka kubadlali nge-analog, ukuxhuma kwe-digital optical / coaxial ne-HDMI. Lapho abadlali beqala ukuqaliswa, ukukhishwa kwevidiyo kuvunyelwe nge- composite, i-S-video, ingxenye, ne-HDMI - kodwa kusukela ngo-2013 konke ukwesekwa kwexhumo yevidiyo nge-composite, i-S-video, nevidyo yevidyo kwaqedwa. Lokhu kusho ukuthi kunoma yisiphi isidlali se-Blu-ray esenziwe kusukela ngo-2013 kuqhubeke, i-TV yakho kufanele ibe ne-HDMI yokufaka ukuze ubuke okuqukethwe kwevidyo.
- Ukuxhumeka kwe-Inthanethi / Inethiwekhi: Nakuba ifomethi ye-Blu-ray isekela ukuxhumeka kwe-intanethi kanye ne-intanethi (BD-Live), ama-intanethi akhiwe ngaphakathi kanye ne-ethernet kuma-Blu-ray Disc Players ngamunye adingeka kuphela kubadlali abenziwe ngemva kukaNovemba 2007. Abadlali abaningi nabo manje abe nenketho yokuxhumana ye-WiFi eyakhelwe ngaphakathi. Futhi, nakuba kungadingeki njengengxenye yezincazelo ze-Blu-ray, abadlali abaningi be-Blu-ray Disc banikeza nokukwazi ukusakaza kwe-intanethi, njengokufinyelela ku-Netflix, Vudu, HuluPlus, njll.
- Ukwesekwa Kwezokukhiqiza Ne-Software: I- Blu-ray isekelwa yibo bonke abakhiqizi abakhulu kanye nama-studio e-movie afaka: Oppo Digital, Denon, Funai, Hitachi, LG, Panasonic, Onkyo, Pioneer, Philips, Samsung, Sharp, Sony, Toshiba, HP, Dell, Apple, TDK, Thomson, ne-Yamaha. I-Blu-ray iphinde isekelwe eceleni kwesofthiwe ngu-Sony / Columbia, Twentieth Century Fox, Disney, MGM, Paramount, Dreamworks, Lionsgate, Warner, ne-Universal, nabanye.
- Ukusekela okuhambisana nokwaziswa okulandelayo: Nakuba ifomethi ye-Blu-ray ayihambisani namafomethi wangaphambilini - ngamanye amazwi, awukwazi ukudlala i-Blu-ray Disc ku-DVD noma kumdlali we-CD, ngaphandle kwenani elilinganiselwe labadlali elitholwa ngaphambi kuka-2008, yonke i-Blu -abadlali be-Disc bangadlala ama-DVD nama-CD, futhi abanye bangadlala i-dis eyengeziwe namafomethi wefayela wesiteshi esivela ku-USB.
I-Blu HD ye-Ultra HD
Ngasekupheleni kuka-2015, i- Ultra HD Blu-ray disk format yathuliswa . Le fomethi isebenzisa ama-discs ofanayo efanayo nefomethi ye-Blu-ray, kodwa yakhiwe ukuze ikwazi ukulingana nolunye ulwazi olusekela ukudlala kwe- Resolution 4K ye-Resolution (lokhu akufani no-4K upscaling olunikezwe kuma-Blu-ray abadlali abajwayelekile) , kanye namanye amakhono okuthuthukisa ividiyo, njenge-gamut ebanzi yombala ne- HDR .
Awukwazi ukudlala i-Ultra HD Blu-ray Disc kumdlali we-Blu-ray Disc standard, kodwa abadlali be-Ultra HD Blu-ray Disc bangadlala ama-Blu-ray, iDVD, nama-CD ajwayelekile, futhi abaningi bangasakaza okuqukethwe kusuka kwi-inthanethi - konke ekuhlakanipheni komkhiqizi.
