ISAZISO: I- HD-DVD inqanyuliwe ngo-2008. Nokho, ulwazi nge-HD-DVD kanye nokuqhathaniswa kwalo ne-Blu-ray kusengaphakathi kwalesi sihloko ngezinhloso zomlando, kanye nokuthi kukhona namanje abanikazi abaningi be-HD-DVD, futhi abadlali be-HD-DVD nama-discs bayaqhubeka bethengiswa futhi bathengiswa emakethe yesibili.
I-DVD
I-DVD iye yaphumelela kakhulu, futhi ngokuqinisekile iyoba khona isikhathi esithile. Kodwa njengoba isetshenziswe, i-DVD ayiyona ifomethi ephezulu-definition. Abadlali be-DVD bavame ukukhipha ividiyo kuma-standard standard ye-NTSC 480i (ama-pixels angu-720x480 kufomethi yokuskena elayishiwe), nabadlali be-DVD abaqhubekela phambili abakwazi ukukhipha ividiyo ye-DVD kuma-480p (ama-pixels angu-720x480 aboniswe ngendlela ekhishwe ngokuqhubekayo). Nakuba i-DVD inesinqumo esiphezulu nekhwalithi yesithombe, uma kuqhathaniswa ne-VHS ne-cable ye-cable ejwayelekile, kuseyingxenye yesixazululo se-HDTV.
Upscaling - Ukuthola okuningi ngaphandle kwe-DVD evamile
Ngomzamo wokwandisa ikhwalithi ye-DVD yokubonisa kuma-HDTVs anamuhla, abakhiqizi abaningi baye bafaka amandla okukhulisa nge- DVI kanye / noma i- HDMI yokuphuma kokuphuma kuma-DVD abadlali abasha.
Upscaling yinqubo eyenza ngezibalo ukulinganisa inani lephikseli kokukhipha isignali yeDVD kumanani wephikseli ngokomzimba kwi-HDTV noma i-Ultra HD TV, okungaba yi- 1280x720 (720p), i-1920x1080 (1080i) , i- 1920x1080p (1080p) , noma i- 3840x2160 (4K) .
Inqubo ye-upscaling yenza umsebenzi omuhle wokufanisa ukukhishwa kwephikseli yedlali yeDVD kwisixazululo sokuboniswa kwe-pixel sokuzalwa kwe-HDTV, okwenza kube nemininingwane engcono kanye nombala ongaguquguquki. Noma kunjalo, i-upscaling ayikwazi ukuguqula izithombe ezijwayelekile zeDVD zibe izithombe eziphezulu zezincazelo eziphezulu.
Ukufika kwe-Blu-ray ne-HD-DVD
Ngo-2006, i-HD-DVD ne-Blu-ray yaziswa. Zombili amafomethi ahlinzeka ikhono lokudlala eliphezulu eliphezulu le-disk, futhi nokukwazi ukurekhoda kuyatholakala nakwamanye ama-PC kanye nama-laptops. I-standalone ye-HD-DVD ne-Blu-ray Disc recorders ayakaze yenziwe itholakale emakethe yase-US, kodwa yenziwa itholakale eJapane namanye amakhemikhali angaphandle kwamanye amazwe. Nokho, kusukela ngo-Ephreli 19, 2008, i-HD-DVD isusiwe. Ngenxa yalokho, abadlali be-HD-DVD abasatholakali.
Ukubhekisela, i-Blu-ray ne-HD-DVD kokubili isebenzisa ubuchwepheshe be-Blue Laser (obunomqondo obukhulu obuncane kunomthamo we-laser obomvu osetshenziselwa i-DVD yamanje). I-Blu-ray ne-HD-DVD yenza i-disc isayizi ye-DVD yamanje yamanje (kodwa, yimuphi umthamo omkhulu wokugcina i-DVD evamile) ukugcina yonke ifilimu ku-HDTV isinqumo noma ukuvumela umthengi ukuthi alobe amahora amabili echazwe ngevidiyo ephezulu okuqukethwe.
I-Blu-ray ne-HD-DVD Ifomethi Yokwakheka
Kodwa-ke, kukhona ukubamba ngokuphathelene nokuchazwa okuphezulu kweDVD ukurekhoda nokudlala. Kuze kube ngo-2008, kwakukhona amafomethi amabili okuncintisana ayengavumelani. Ake sibuke ukuthi ubani owayesemva kwesakhiwo ngasinye nokuthi yiyiphi indlela enikezwa ngayo, futhi, uma kwenzeka i-HD-DVD, lokho okwenziwe.
Ukusekelwa kwefomethi ye-Blu-ray
Ekuqaleni kwalo, i-Blu-ray ekuqaleni isixhaswe eceleni kwe-hardware yi-Apple, i-Denon, i-Hitachi, i-LG, i-Matsushita (i-Panasonic), iphayona, i-Philips, i-Samsung (nayo ixhaswe i-HD-DVD), i-Sharp, i-Sony ne-Thomson (Qaphela: U-Thomson naye wasekela i-HD-DVD).
Ehlangothini lwesofthiwe, i-Blu-ray ekuqaleni isixhaswe yiSions Gate, MGM, Miramax, Twentieth Century Fox, i-Walt Disney Studios, i-New Line, ne-Warner. Noma kunjalo, njengomphumela wokuqedwa kwe-HD-DVD, i-Universal, Paramount, ne-Dreamworks manje seyikho nge-Blu-ray.
Ukusekelwa kwefomethi ye-HD-DVD
Lapho i-HD-DVD isetshenzisiwe yayisekelwe eceleni kwe-hardware nge-NEC, i-Onkyo, i-Samsung (nayo isekela i-Blu-ray) i-Sanyo, i-Thomson (Qaphela: i-Thomson nayo isekela i-Blu-ray), no-Toshiba.
Ehlangothini lwesofthiwe, i-HD-DVD isekelwe yi-BCI, Dreamworks, Paramount Pictures, I-Canal, ne-Universal Pictures, ne-Warner. IMicrosoft nayo yaqala ukusekela i-HD-DVD, kodwa ayisekho, emva kokusekelwa kwe-Toshiba nge-HD-DVD ngokusemthethweni.
QAPHELA: Yonke i-HD-DVD hardware kanye nokwesekwa kwesofthiwe kukhishiwe futhi yashintshwa ku-Blu-ray maphakathi no-2008.
I-Blu-ray - Imininingwane Ejwayelekile:

- Ikhono lomnethiwekhi: Nakuba ifomethi ye-Blu-ray isekela ukuxhumana nokuxhumeka kwe-intanethi, izintandokazi zokuxhumana nezindawo ze-ethernet kumuntu ngamunye we-Blu-ray Disc Players zazikhethela ezimbhangqwaneni zokuqala zezizukulwane. Noma kunjalo, cishe bonke abadlali be-Blu-ray Disc banikeza ukuxhumeka kwe-intanethi nokuxhumeka kwenethiwekhi. Bheka imikhiqizo ethile namamodeli ongase ucabange ngawo.
I-HD-DVD - Imininingwane Ejwayelekile
- Ikhono Lokugcina - Izinto zokudlala ezandulele ngaphambilini (i-HD-DVD-ROM): I- single-layer (15GB) - I-Double Ground (30GB) - I-Triple Layer (51GB - ithuthukiswe, kodwa ayizange ifakwe emakethe).
- Amandla okugcina - Ukurekhoda Kwekhaya (i-HD-DVD-R / HD-DVD-Inzuzo): Uhlaka olulodwa (20GB) - I-Disc Okubili Ephakathi (40GB) - I-Layer Double (35GB - ehlongozwayo).
- Isilinganiso sokudluliswa kwedatha: 36 MBPS (iMegabits ngayinye yesibili) - Lokhu kudlula izinga lokudlulisa le-19.3 Mbps elivunyelwe ukuhanjiswa kwe-HDTV.
- Izakhiwo zeDiski: Ukufometha okufana nesakhiwo se-disc disc esivele sikhona, okudinga ukuthuthukiswa okuncane nokubuyisela kabusha ukukhiqizwa kwe-disc disc kanye nezitshalo zokuphindaphinda.
- Ukucaciswa kwevidiyo: Iyahambisana ne-MPEG2, MPEG4, ne-VC1 Ukucubungula. I-3D ayizange ihlanganiswe njengengxenye yezinketho ze-HD-DVD njengoba ifomethi ishiyiwe ngaphambi kokuba kuqaliswe i-3D.
- Imininingwane Yomsindo: Bonke abadlali be-HD-DVD kwakudingeka ukuba bahlanganise okulandelayo - i-Dolby Digital Plus, i-Dolby TrueHD, i-DTS-HD, ne- PCM engaxhunyiwe, kanye ne-Dolby Digital ne-DTS ejwayelekile.
- Amandla enethiwekhi: Bonke abadlali be-HD-DVD kwakudingeka babe inethiwekhi amandla futhi bahlomele i-port e-Ethernet eyakhelwe ngaphakathi ekulayisheni izibuyekezo ze- firmware nezinye izici ezisebenzayo.
Ifomethi ye-Blu-ray Disc kanye namaphrofayli omdlali
Ngaphandle kokufometha okuyisisekelo kwe-Blu-ray Disc kanye nokucaciswa komdlali. Kukhona "Amaphrofayli" amathathu okuthengwa ngabathengi. Lezi ziprofetho zibandakanya amakhono ama-Blu-ray Disc abadlali, futhi asetshenzisiwe yi-Blu-ray Disc Association kanje:
- Iphrofayela ye-1.0 - Le phrofayela ihlanganisa bonke abadlali be-Blu-ray Disc eyenziwe ngaphambi kukaNovemba 2007. Abadlali kuleso sigaba bane-single decoder video futhi akukho uxhumano lwe-intanethi. Lokhu kusho ukuthi laba abadlali abakwazi ukufinyelela ku-PIP (Isithombe-ku-Isithombe) okuqukethwe okuhlanganisiwe kuma-Blu-ray Discs, futhi abakwazi ukufinyelela okuqukethwe okunikeziwe ngeWeb kuhlanganiswe kuma-Discs Blu-ray. Njengombhalo ohlangothini, bonke abadlali be-HD-DVD badinga ukuthi babe namakhono akhelwe ngaphakathi kusuka ngosuku olulodwa.
- Iphrofayili 1.1 - Le phrofayili ineza iprosesa yesibili yomsindo / yevidiyo kanye nokugcinwa kwememori engu-256 MB kuzo zonke izinhlobo ze-Blu-ray zeDiski ezenziwe ngemuva komhla kaNovemba 1, 2007. Lokhu kuvumela ukufinyelela kokuqukethwe okuhlaziyikayo kwe-PIP kanye nezinye izici ezisebenzayo ezifakiwe kwi-Blu- ama-Disc Disc (okubizwa nangokuthi "Bonus View"). Amanye ama-1.1 abadlali futhi bavumela ukufinyelela okuqondile ukuthuthukiswa kwe-firmware okutholakala kuwebhu. Kodwa-ke, akudingeki ukuthi isidlali se-Blu-ray Disc sinokuxhumeka kwe-intanethi ukufaneleka njenge-Profile 1.1 ehambisanayo nomdlali.
- Iphrofayli 2.0 - Le phrofayela ibizwa ngokuthi "BD-Live". Ifana nephrofayela 1.1, kodwa ineza amandla okugcina imemori ye-1GB futhi idinga ukufakwa kokuxhumeka kwe-Ethernet, okuvumela ukuguquguquka okwengeziwe ekufinyeleleni izici ezengeziwe ezingase zifakwe kuma-Blu-ray Discs kanye nokufinyelela okungaphezulu kwe-web-enabled enabled feature i-port enkulu ye-intanethi. Lokhu kuletha ifomethi ye-Blu-ray Disc endaweni efanayo ne-HD-DVD abadlali bevela ekusungulweni kokuqala kwaleso fomethi manje.
Inhloso yukuthi yonke i-Blu-ray Discs, kungakhathaliseki ukuthi i-Profile iboshelwe kuyo, izobe idlale kuwo wonke ama-Blu-ray Disc abadlali. Noma kunjalo, noma yikuphi okuqukethwe okukhethekile okudinga i-Profile 1.1 noma 2.0 ngeke kutholakale kubadlali be-Profile 1.0, futhi okuqukethwe okuqondene ne-Profile 2.0 ngeke kufinyeleleke yi-Profile 1.0 noma 1.1 isidlali esilungisiwe.
Ngakolunye uhlangothi, abanye abadlali be-Profile 1.1 bangaba i-firmware kanye nokukhumbuza imemori (ngekhadi le-flash yangaphandle), uma nje bevele benokuxhumeka kwe-ethernet nokuxhumeka kokufaka kwe-USB, kuyilapho i-Sony Playstation 3 Blu-ray ekhonjiwe ikhonsoli yemidlalo ingathuthukiswa kuphrofayela I-2.0 kuphela ukuthuthukiswa kwe-firmware yokuthuthukisa.
QAPHELA: I-HD-DVD ifomethi ayiklanyelwe uhlelo lwephrofayela. Bonke abadlali be-HD-DVD akhululwe, kuze kube yilapho ukuyeka kwabo, kusukela ekubizeni okungenani kakhulu, kuya kubabizayo, abasebenzisi abavumelekile ukufinyelela kuzo zonke izici ezisebenzisanayo ne-intanethi ezihambisana nama-HD-DVD afaka izici ezinjalo.
Yeka ukuthi i-Blu-ray ne-HD-DVD yenzani uMakethe Wathengi
Ngokusekelwe kokusekelwa kwe-hardware okubanzi ngabafaki befomethi ye-Blu-ray, kungabonakala sengathi i-Blu-ray ithandana elinengqondo evele njengendlela evamile yokudlala i-high-definition disc, kodwa i-HD-DVD inenzuzo eyodwa eyodwa. Ngeshwa, leyo nzuzo ayikwazanga ukunqoba ukwesekwa okuqhubekayo kwe-Blu-ray.
I-Blu-ray, izakhiwo ezintsha kwakudingeka ukukhiqiza ama-disks nabadlali kanye nokuphindaphinda kwe-movie disc. Kodwa-ke, ngenxa yokuthi imininingwane ye-HD-DVD yayifana kakhulu neDVD ejwayelekile, izitshalo eziningi zokukhiqiza okwenza amanje ama-DVD abadlali, ama-disks, nokukhishwa kwe-movie angasetshenziswa i-HD-DVD.
Ngesikhathi i-HD-DVD inenzuzo ngokuqondene nokuqala kokukhiqiza kokuqala, ngezindleko zokuqala ezingase zibe phansi, inzuzo eyinhloko ye-Blu-ray nge-HD-DVD ingumthamo wokugcina. Ngenxa yesikhumulo esikhulu se-disk, i-Blu-ray disc ingakwazi kalula ukufaka amafilimu nezici ezengeziwe.
Ukuqeda lokhu, i-HD-DVD yayisetshenzisile ama-disk multi-layered discs, futhi isebenzisa ubuchwepheshe bokucindezela i-VC1, okuvumela okuqukethwe okungaphezulu, ngaphandle kokulahlekelwa kwekhwalithi, kwi-disc yayo encane yesitoreji somthamo. Lokhu kunikwe amandla ifomethi ye-HD-DVD ukufaka izici ezengeziwe namafilimu amade kudoti elilodwa.
I-Blu-ray ne-HD-DVD Ukutholakala
Abadlali be-Blu-ray Disc batholakala kabanzi emhlabeni wonke, kuyilapho abadlali abasha be-HD-DVD bengatholakali, amadivaysi asetshenzisiwe noma angasetshenziswa nge-HD-DVD angase atholakale ngamaqembu abo (njenge-eBay). Kusukela ngo-2017, akusekho ama-Recorder Blu-ray e-standalone abasebenzisi abakhululiwe emakethe yaseNyakatho Melika.
Enye yokubamba ukutholakala kwe-Blu-ray Disc yokuqopha (i-HD-DVD ayisona isici) yizimpawu zokukopisha-ukuvikelwa okuzohlangabezana nezidingo zomabonakude nama-studio e-movie. Futhi, ukuthandwa kwe-HD-TIVO ne-HD-I-Cable / I-Satellite DVRs kuyinkinga yokuncintisana.
Ngakolunye uhlangothi, kukhona abalobi befomethi ye-Blu-ray yama-PC. Kukhona futhi amarekhoda ambalwa we- Blu-ray Disc atholakalayo ekusetshenzisweni kobuchwepheshe, kodwa angenawo amathrekhi we-HDTV anakhelwe ngaphakathi futhi awunayo imibono yevidiyo ephezulu yokuchaza. Indlela kuphela yokungenisa ividiyo ephezulu yokuchaza kulezi zinyunithi ngokuxhumeka kwekhamera ye-high definition (nge-USB noma i-Firewire) noma ngevidiyo ecacile egciniwe egcinwe kuma- flash drive noma imemori khadi.
Kukhona amafilimu kanye nokuqukethwe kwevidiyo okutholakala kokubili kwe-Blu-ray ne-HD-DVD format (Ukukhishwa okusha kwe-HD-DVD lapho kuqedwa ngasekupheleni kuka-2008). Kuneziqu ezingaphezu kuka-20,000 ezitholakalayo ku-Blu-ray, ezinezihloko ezikhishwe ngesonto onke. Futhi, kunezinkulungwane eziningana zokukhishwa kwe-HD-DVD ezisekhona emakethe yesibili. Amanani wezinhlamvu ze-Blu-ray angama-$ 5-noma- $ 10 ngaphezu kwama-DVD wamanje. Amanani amabhayisikobho, njengalabo abadlali, qhubeka ehla ngokuhamba kwesikhathi, njengoba ukuncintisana ne-DVD evamile kukhula. Kukhona manje abadlali be-Blu-ray Disc abanani eliphansi njenge $ 79.
Ikhodi ye-Blu-ray yekhamera:
- Isifunda A: US, Japan, Latin America, East Asia (ngaphandle kweChina).
- Isifunda B: IYurophu, i-Afrika, i-Australia, i-New Zealand
- Isifunda C: China, Russia, amazwe asele.
Kukhona (kwakungekho) ukuCoding kwesifunda okusetshenziselwe i-HD-DVD.
Ezinye Izinto
Ngenkathi ukusungulwa kwe-Blu-ray ne-HD-DVD kubonakalisa umcimbi obalulekile kumlando wabathengi we-electronics, futhi i-Blu-ray yenza ukubonakala okuphawulekayo ekudayiseni kokubili abadlali nesofthiwe, ngeke kuhlinzeke iDVD engasebenzi. I-DVD njengamanje ifomethi yokuzijabulisa ephumelele kunazo zonke emlandweni, futhi bonke abadlali be-Blu-ray Disc (nanoma yibaphi abadlali be-HD-DVD abasasebenza) bangadlala ama-DVD ajwayelekile . Lokhu kwakungenjalo nge-VHS kuya kwezinguquko ze-DVD, njengoba abadlali be-DVD / VHS ama-combo bengangeni emakethe kuze kube neminyaka ethile emva kokufakwa kweDVD.
Nakuba ama-Blu-ray ne-HD-DVD abadlali bebuyele emuva ehambisana neDVD evamile, azihambisani. Ukurekhoda nama-movie ngesakhiwo esisodwa ngeke kudlale kunoma iyiphi enye amayunithi wefomethi. Ngamanye amazwi, awukwazi ukudlala ibhayisikobho ye-Blu-ray kusidlali se-HD-DVD, noma ngokufanayo.
Izixazululo Ezingahle Zingase Zisombulule Izingxabano ze-Blu-ray ne-HD-DVD
Isixazululo esisodwa esingaxazulula ukungahambisani kwe-Blu-ray Disc ne-HD-DVD senziwe yi-LG, sethule isidlali somculo we-Blu-ray Disc / HD-DVD. Ukuze uthole imininingwane eyengeziwe, hlola ukubuyekeza kwami kwe-LG BH100 Blu-Ray / HD-DVD Super Multi Disc Blue Player . Ngaphezu kwalokho, i-LG iphinde yafaka i-Combo yokulandela, i-BH200. I-Samsung iphinde ithule isidlali se-Blu-ray Disc / HD-DVD. Manje ukuthi i-HD-DVD ayisekho, cishe akunakwenzeka ukuthi abadlali abasha be-combo bazokwenziwa.
Ngaphezu kwalokho, amakamu ama-Blu-ray ne-HD-DVD ayebonise ukuthi angaveza i-disc hybrid engaba yi-DVD evamile ngakolunye uhlangothi noma i-Blu-ray noma i-HD-DVD komunye. Ama-disk hybrid ama-HD-DVD / DVD ayatholakala kuze kube sekupheleni kwendlela. Abanikazi bamanje bama-discs banokufinyelela ku-version evamile ye-DVD engadlalwa kunoma iyiphi umdlali wefomethi, nakuba engekho kwifomu yayo ephezulu-definition.
Futhi, u-Warner Bros umemeze futhi wabonisa i-disc hybrid ye-Blu-ray / HD-DVD. Lokhu kuzokwenza ukuthi ifilimu noma uhlelo lubekwe kwi-disc eyodwa kumafomethi we-Blu-ray ne-HD-DVD. Ngenxa yalokho, akunandaba ukuthi yimuphi umfaki wefomethi ongayithola. Kodwa-ke, njengoba i-HD-DVD isusiwe manje, i-hybrid ye-Blu-ray / HD-DVD ngeke isetshenziswe.
Ulwazi oluningi
