Lokho I-Letters & # 34; DVD & # 34; Empeleni Yima
I-DVD imele iDiski ehlukahlukene yeDiski . Ama-DVD angasetshenziswa ukugcina ividiyo, umsindo, isithombe, noma idatha yekhompyutha. Abantu abaningi babheka i-DVD njengeDivid Video Disc , Nokho, ngokweqiniso, lokhu akulungile.
Yini eyenza i-DVD ihluke kune-VHS
I-DVD ihluke ku-VHS ngezindlela ezilandelayo:
- Ku-VHS, ulwazi lwama-audio nolwazi lwevidiyo lufakwe emshinini we-magnetic oqoshwe ku-videotape, efundwa yinhloko ejikelezayo ku-VCR. Ukuze i-DVD, ulwazi lwevidiyo neyomsindo luhlanganiswe emigodini efundwa yi-laser.
- Okumangalisa ukuthi i-DVD ngokomzimba ihambisana kakhulu nerekhodi le-vinyl yendabuko kunevidiyo yevidiyo. Izimpawu zomsindo kwirekhodi le-vinyl zifakwe emanzini omzimba, afundwa ngokomzimba nge-stylus. Umehluko, ngaphandle kwe-groove vs ukukhipha ama-cits disc, ukuthi isignali kwirekhodi ye-vinyl iyinhlobo ye-analog waveform futhi isignali kwi-DVD yizinkinobho zedijithali.
- I-DVD isekela kokubili izilinganiso zesici sesibuko se- screen ye-16x9 nesibuko esibucayi se-anamxphic.
- I-DVD iyakwazi ukuhlinzeka kabili ukulungiswa kwevidiyo kune-VHS, okwenzela isithombe esinemininingwane eningi nokulinganisa okungcono kombala. Kodwa-ke, nakuba i-DVD inikeza isinqumo esiphezulu kune-VHS, akuyona ifomethi yeqiniso ephezulu yeqiniso - okuningi kulokhu ku-"Upscaling DVD Players" ingxenye yalesi sihloko.
- Ungakwazi ukufinyelela noma yikuphi ingxenye yeDVD ngendlela engahleliwe noma esheshayo, kuyilapho kufanele uqhube phambili noma uphinde uvuselele i-VHS tape ukuze uthole indawo ethile kwi-tape.
- I-DVD isekela amamenyu asebenzisanayo nezici ezengeziwe, njengezingoma eziningi zamagama, amazwana okulalelwayo, nezinye izici ezingatholakali kwifomethi ye-VHS. I-DVD nayo isekela amazwibela avaliwe ne-On / Off Subtitling ngezilimi eziningana.
- I-DVD isekela ukubuka okubonakalayo kwekhamera eminingi ehambisanayo, unikezwe ukuthi umenzi wefilimu uhlinzeke ngenye indlela yama-camera footage shot ngesikhathi inqubo yokuqopha kubasebenzi bokukhiqiza i-DVD (lesi sici asivami ukusetshenziswa).
- Ama-DVD awaphethwe yizinkinobho zamagnetic. I-DVD yezohwebo ayikwazi ukusulwa.
Ukwenza ikhodi ye-DVD

Izwe lihlukaniswe ngezifunda eziningana zeDVD. Abadlali beDVD bangadlala kuphela ama-DVD aqoshiwe esifundeni esithile.
Kodwa-ke, kukhona abadlali be-DVD abatholakala ukuthi bangadlula uhlelo lweKhodi yeSifunda. Lolu hlobo lwe-DVD player libizwa ngokuthi i-Code Free DVD player.
Ukuze uthole incazelo egcwele ye-DVD Region Amakhodi, Izifunda, kanye Nezinsiza ze-Code Free DVD Players, bheka isihloko sethu somngane: Amakhodi Wendawo - Imfihlo Ye-DVD Engcolile .
Ukufinyelela Umsindo On A DVD
Enye yezinzuzo ze-DVD yikhono layo lokunikeza izinketho eziningi zokulalelwayo kwi-disc.
Nakuba umsindo kwi-DVD yedijithali, ingafinyelelwa ku-analog noma ifomu ledijithali. Abadlali be-DVD banemiphumela ejwayelekile ye-audio stereo analog engakwazi ukuxhumeka kunoma iyiphi isistimu ye-stereo noma i-TV ye-stereo eneziphakamiso zomsindo we-stereo. Abadlali be-DVD banemiphumela yomsindo wedijithali engakwazi ukuxhumeka kunoma iyiphi isamukeli se-AV eneziphakamiso zomsindo wedijithali. Kumele usebenzise ukuxhuma kwe- digital optical noma i-digital coaxial audio ukuze ufinyelele umsindo we-surround sound we- Dolby Digital noma we- DTS 5.1 .
Ukuxhumeka kwevidiyo ye-DVD Player
Abaningi be-DVD abadlali banevidiyo ejwayelekile ye- RCA , i- S-video , neziphumo zevidiyo ze-Component Video .
Kulabadlali abaningi be-DVD, iziphumo zevidiyo ezingenayo zingadlulisela isignali yevidiyo ejwayelekile phakathi noma isignali yevidiyo yokusakaza ku-TV (ngaphezulu kwalokho kamuva kulesi sihloko). Abadlali abaningi be-DVD banemiphumela ye-DVI noma ye- HDMI yokuxhuma okungcono kuma-HDTV. Abadlali be-DVD ngokuvamile abanalo i-antenna / iziphumo zekhebula.
Ukusebenzisa i-DVD Player ene-TV Enayo kuphela i-Antenna / Connection Cable
Into eyodwa abakhiqizi abazange baziphendule: isidingo sokuba abadlali bakwazi ukuxhuma ekufakeni i-antenna / ikhebula ejwayelekile kuma-TV andala ase-analog.
Ukuxhuma isidlali se-DVD ku-TV ene-antenna / uxhumano lwekhebula, udinga idivayisi ebizwa ngokuthi i- RF Modulator , ebeka phakathi kwe-DVD player ne-TV.
Ukuze uthole imiyalelo yesinyathelo esinezinyathelo zokuxhuma i-modulator ye-RF, i-TV, ne-DVD isidlali ndawonye, bhekani ku- Setup bese usebenzisa i-RF Modulator ene-DVD Player ne-Television
Ama-DVD ama-movie nama-DVD ayenziwa kwi-DVD Recorder noma i-PC
Amabhayisikobho e-DVD owathengayo noma oqashisayo anezici ezihlukile kunezingqikithi zamaDVD ozenza ekhaya kwi-PC noma i- DVD yokuqopha .
Amafomethi okuqopha ama-DVD okusetshenziselwa abathengi afana nesakhiwo esetshenziselwa ama-DVD angaphandle, okuthiwa yi-DVD-Video. Noma kunjalo, indlela ividiyo erekhodiwe ngayo i-DVD ihlukile.
Zombili ama-DVD azenzele futhi ezentengiselwano asebenzisa "izigobo" kanye "nezibhamu" ezidalwe ngokomzimba kuma-discs ukugcina ulwazi nevidiyo yomsindo, kodwa kukhona umehluko phakathi kokuthi "ama-pits" kanye "nama-bumps" adalwe kuma-DVD athengiswayo ngekhaya ama-DVD aqoshiwe.

Abadlali be-DVD ne-Scan Progressive
Ividiyo evamile, efana ne-VHS VCRs, amakhamera, kanye nemisakazo eminingi ye-TV iboniswa esikrinini (njenge-CRT display) ngenxa yochungechunge lwezintambo zomugqa kwendawo yeskrini kufomethi ebizwa nge-scan interlaced. Hlanganisa ukukhipha imigqa yevidiyo ekhonjiswe ngenye indlela kwesikrini se-TV. Yonke imigqa engavamile ihlolwe kuqala, ngakho yonke imigqa. Lezi zibhekwa njengamasimu.
Ifreyimu ehlongozwa ngaphakathi ihlanganiswe ngamasimu amabili evidiyo (yilapho igama "ukuskena okuphambene" livela). Nakuba ama-video ozimele aboniswa zonke izikhathi ezingu-30 zesibili, umbukeli, kunoma yiliphi iphuzu elithile ngesikhathi esifanayo ubona isigamu sesithombe kuphela. Njengoba inqubo yokuskena ishesha kangaka, umbukeli ubona ividiyo esikrinini njengesithombe esiphelele.
Izithombe zokuskena eziqhubekayo ziyahlukahluka kwezithombe ezithwetshaniswa ngaphakathi lapho isithombe siboniswa esikrinini ngokuskena umugqa ngamunye (noma umugqa wamaphikseli) ngokulandelana okulandelanayo kunokulandelana okunye. Ngamanye amazwi, imigqa yesithombe (noma imigqa yamaphikseli) iskenwa ngokulandelana kwezinombolo (1,2,3) phansi kweskrini kusukela phezulu kuya phansi, esikhundleni somunye umyalelo (imigqa noma imigqa 1,3,5, njll. .. kulandelwa imigqa noma imigqa 2.4,6).
Ngokuskena isithwebuli ngokuqhubekayo esibukweni njalo kunama-60 wesibili kunokuba "ulandelele" imigqa eminye imizuzu engama-30 yesibili, elula futhi eningiliziwe, izithombe zingakhishwa esikrinini esilungele ukubuka imininingwane emihle, njengombhalo futhi futhi kuncane kakhulu ongakwazi ukugubha.
Ukuze ufinyelele isici sokuskena okuqhubekayo se-DVD player, kufanele ube ne-TV engabonisa izithombe ezithwetshulwa ngokuqhubekayo, njenge- LCD , iPlasma , i- OLED TV, noma iprojekthi yevidiyo ye- LCD ne- DLP .
Isici sokuskena se-player isidlali seDVD singacinywa noma sivuliwe. Lokhu kusho ukuthi usengasebenzisa isidlali nge-TV engabonisa kuphela izithombe ezithwetshwe ngaphakathi (njenge-CRT endala).
Ukuze uthole imininingwane eyengeziwe, bheka kusihloko sethu somngane: Iskena Esiqhubekayo - Okudingeka Ukwazi .
Indlela abadlali be-DVD abakwazi ngayo ukudlala ama-CD
Ama-CD nama-DVD, nakuba ahlanganyela okufana okuyisisekelo, njengokwama-discs, i-video encoded video, alalelwayo, noma / noma namanje isithombe sithombe sigxiliwe (ukuhweba) noma sishisiwe (ikhaya eliqoshiwe) - lihlukile.
Umehluko oyinhloko wukuthi ubukhulu bezintambo noma ukushiswa kwama DVD namaCD ahlukile. Ngenxa yalokho, yilowo nalowo udinga ukuthi i-laser yokufunda ithumele isigxobo sokukhanya se-wavevel ehlukene ukuze ufunde ulwazi ngohlobo ngalunye lwe-disc.
Ukuze ufeze lokhu, umdlali we-DVD unesici sezinto ezimbili: I-laser enekhono lokuguqula ukugxila kwayo ngokunembile ngokusekelwe kwiDVD noma i-CD ukutholakala noma, ngokuvamile, umdlali we-DVD uyoba nama-lasers amabili, enye yokufunda i-DVD kanye neyodwa yokufunda ama-CD. Lokhu kuvame ukubhekiswe eMhlanganweni We-Twin-Laser.
Esinye isizathu sokuthi abadlali beDVD bangadlala ne-CD akuyona ezobuchwephesha kodwa kuyindlela yokuthengisa yokuqaphela. Ngesikhathi i-DVD iqala ukuthengiswa emakethe ngo-1996-1997, kunqunywa ukuthi enye yezindlela ezinhle kakhulu zokwandisa ukudayiswa kwabadlali beDVD futhi yenza ukuba bakhangise kakhulu abathengi kwakuzofaka futhi ikhono lokudlala ama-CD. Ngenxa yalokho, umdlali we-DVD empeleni waba amayunithi amabili kwesinye, umdlali we-DVD nomdlali we-CD.
Okungcono Kokudlala Ama-CD - I-DVD Player noma Umdlali we-CD kuphela?
Yize amanye ama-processing processing circuit ayabelwe, izidingo eziyisisekelo kokuhambisana kweCD kanye neDVD zihlala ngokwahlukana ngaphakathi kwe-chassis efanayo.
Uma ngabe bonke abadlali beDVD bangama-CD abadlali abangcono, akuzona zonke. Kufanele uqhathanise nabo-unit-by-unit. Kodwa-ke, abaningi abadlali be-DVD empeleni badlala kakhulu abadlali be-CD. Lokhu kungenxa yezigaba zabo zokucubungula okuphezulu kokulalelwayo. Futhi, ngenxa yokuthandwa kwabadlali be-DVD, kuba nzima ukuthola abadlali be-CD kuphela. Abaningi abadlali be-CD kuphela abakhona kulezi zinsuku ziyizigaba zamatayipi angama-middle or end-single, kanye nabadlali abambalwa be-carousel. Abadlali be-jukebox ye-CD ne-DVD babeningi kakhulu, kodwa baye bawela eceleni.
Ama-DVD ama-Superbit
Ama-DVD ama-Superbit ama-DVD asebenzisa wonke isikhala se-movie kanye ne-soundtrack-akukho okungeziwe okufana namazwana noma ezinye izinto ezikhethekile ezifakiwe kwi-disc efanayo. Isizathu salokhu ukuthi inqubo ye-Superbit isebenzisa lonke izinga elincane (ngaleyo ndlela igama elingu-Superbit) le-disc ye-DVD, okwandisa ikhwalithi yefomethi yeDVD. Imibala ine-depth and variation eyengeziwe futhi kunezinkinga ezingezansi ezingxenyeni ze-artifact kanye nezindaba zomsindo wevidiyo. Cabanga ngokuthi "i-DVD eyithuthukisiwe".
Kodwa-ke, nakuba ama-DVD ama-Superbit anikeza ukuthuthukiswa kwekhwalithi yesithombe kuma-DVD ajwayelekile, ayikafani ne-Blu-ray disc.
I-DVD ye-Superbit iyadlala kuwo wonke ama-DVD ne-Blu-ray Disc abadlali. Nokho, kusukela ekusungulweni kwe-Blu-ray, i-Superbit DVD ayisakhululwa.
Ukuze uthole imininingwane eminingi nge-Superbit DVD, bhekisela ku-Look ku-Superbit (i-DVD Talk) nohlu lwazo zonke iziqu ze-Superbit DVD ezikhishwe (phawula ukuthi isixhumanisi se-Now Available asisasebenza) kanye nokuqhathanisa okuhle kakhulu phakathi kwe Standard I-DVD ne-Superbit DVD.
I-DualDisc
I-DualDisc iyinhlangano engavumelani lapho i-disc ine-layer ye-DVD ngakolunye uhlangothi kanye nohlaka lwe-CD-uhlobo kolunye. Njengoba i-disc ine-thickness ehlukile kune-DVD evamile noma i-CD evamile, kungenzeka ukuthi ingabi nokuhambisana okuphelele kokudlala kwabanye abadlali be-DVD. Ama-DualDiscs awaqashelwa ngokomthetho njengemininingwane ye-CD yokuhlangana. Ngenxa yalokho, i-Philips, abathuthukisi be-CD nabanikazi bezincwadi eziningi ze-CD, abagunyazisi ukusebenzisa i-label esemthethweni ye-CD ku-DualDiscs.
Ukuze uthole ulwazi lokuthi ngabe i-DVD yakho siqu idinga yini i-DualDisc, hlola umhlahlandlela wakho womsebenzisi, uxhumane noxhaso lwe-tech, noma uye ekhasini lewebhu lomenzi wesidlali sakho se-DVD.
Ama-Discs Blu-ray / DVD Flipper
Enye i-disc ye-"Double" i-disc ye-Blu-ray / DVD ye-flipper. Loluhlobo lwe-disc luyi-Blu-ray ngakolunye uhlangothi, ne-DVD kolunye. Kokubili izingxenye ze-Blu-ray ne-DVD zingadlalwa kumdlali we-Blu-ray Disc, kodwa kuphela uhlangothi lwe-DVD lungadlalwa kumdlali we-DVD. Kunamabhayisikobho ambalwa kakhulu atholakala kwi-Disc-Blu-ray flipper Disc.
I-HD-DVD / DVD ye-Combo Discs
Ngokufana ne-disc-Blu-ray flipper, i-HD-DVD / iDVD yama-disbo disc i-HD-DVD ngakolunye uhlangothi, ne-DVD kwenye. Kokubili izingxenye ze-HD-DVD ne-DVD zingadlalwa kumdlali we-HD-DVD, kodwa kuphela i-DVD side engadlalwa kumdlali we-DVD.

I-DVD Yonke Abadlali
Isidlali se-DVD jikelele sibhekisela kumdlali we-DVD odlala i- SACDs (i-Super Audio CD) ne-DVD-Audio Discs kanye namaDVD nama-CD ajwayelekile.
I-SACD ne-DVD-Audio yizifomethi zokulalelwayo eziphezulu ezihloselwe ukufaka esikhundleni somculo ojwayelekile we-CD kodwa azange zenze umthelela omkhulu emakethe nabathengi. Abadlali be-DVD yonke baneqoqo lemiphumela yomsindo we-analog wesiteshi esingu-6 ovumela umthengi ukuthi afinyelele i-SACD ne-DVD-Audio kumamukeli we-AV obuye abe nomthelela womsindo we-analog wesiteshi 6.
Ngenxa yokungafani ngendlela ye-SACD ne-DVD-Audio izimpawu ezifakiwe kwi-disc, isidlali seDVD kufanele siguqule isignali kufomu le-analog njenge-digital optical kanye ne-digital coaxial uxhumano kumdlali weDVD osetshenziselwa ukufinyelela ku-Dolby Digital ne-DTS imisindo ayihambisani nemisindo ye-SACD noma ye-DVD-Audio.
Ngakolunye uhlangothi, izimpawu ze-SACD ne-DVD-Audio zingadluliswa nge-HDMI, kodwa leyo ndlela ayitholakali kubo bonke abadlali. Futhi, uma kwenzeka izimpawu ze-SACD, ukuze zidluliselwe nge-HDMI, ivame ukuguqulwa ku- PCM
Ukuqeda i-DVD Players
I-Upscaling DVD player iyunithi ehlomelelwe nge-DVI noma i-HDMI uxhumano. Lezi zixhumanisi zingadlulisa ividiyo kusuka kumdlali weDVD kuya kwi-HDTV enesimo esifanayo soxhumano lwevidiyo kwifomu ye-digital ehlanzekile, kanye nokuvumela "ukukhishwa kwe-upscaling".
Isidlali se-DVD esivamile, ngaphandle kokuphakamisa, singakhipha isinqumo sevidiyo ngo-720x480 (480i). Isidlali se-DVD esiqhubekayo sokuskena, ngaphandle kwe-upscaling, singakhishwa ama-video angu-720x480 (ama-480p - okuqhubekayo okuskena).
Upscaling yinqubo eyenza ngezibalo ukulinganisa inani lephikseli kokukhipha kwesignali yeDVD kumbalo wepikseli ngokomzimba kwi-HDTV, ngokuvamile eyi- 1280x720 (720p) , 1920x1080 ( 1080i noma 1080p .
Ngokubukeka, kukhona umehluko omkhulu emehlweni omthengi ophakathi phakathi kuka 720p noma 1080i . Kodwa-ke, i-720p ingaletha isithombe esibhekene nesisindo esincane, ngenxa yokuthi imigqa namaphikseli aboniswa kwiphethini elilandelanayo, kunokuba kusetshenziswe enye iphethini. Uma une- 1080p noma i- 4K Ultra HD TV - isilungiselelo se-1080p sizoletha imiphumela engcono kakhulu.
Inqubo ye-upscaling yenza umsebenzi omuhle wokufanisa ukukhipha kwephikseli okuphakanyisiwe kwesidlali seDVD kusixazululo sokubonisa umbukiso we-pixel we-TV ye-HDTV, okwenza kube nemininingwane engcono kanye nokungafani kombala.
Noma kunjalo, i-upscaling ayikwazi ukuguqula izithombe ezijwayelekile zeDVD zibe yividiyo yeqiniso ephezulu. Nakuba i-upscaling isebenza kahle ngama-pixel ahleliwe, njengama-Plasma, i-LCD, nama-TV e-OLED, imiphumela ayihlali ihambisana ne-TV ephezulu ye-TV ephezulu.
Ngaphandle kweDVD - I-Blu-ray Disc
