Bhala uhlu lwezingxenye zalo mbhalo uhlu oluhlukaniswe ngama-comma
Context:Izingxenye Ngezansi kunezingxenye nezinqubo ezihilelekile ku-digital supply chain, ngokulandelana okulandelanayo, ukuletha okuqukethwe okuluhlaza kufomethi etholakala kumthengi ngekhompyutha yomuntu siqu noma nge-set-top box:  Umhlinzeki Wokuqukethwe Umhlinzeki wokuqukethwe uhlinzeka ngokuqukethwe kwangempela okuzodliwa ekugcineni ngumsebenzisi wokugcina. Umhlinzeki wokuqukethwe unikeza okuqukethwe ngezindlela ezihlukahlukene - kuhlanganise ifilimu, i-tape, i-CD, i-DVD, ama-hard disk namafayela edijithali.  Ukubamba Uma okuqukethwe okunikezwe ngumhlinzeki wokuqukethwe kungakabi ngefomethi yedijithali, kufanele kuqala kuguqulwe kube ngefomethi yedijithali. Endabeni yefilimu noma i-tape, lokhu kuvame ukubizwa ngokuthi inqubo ye- "capture" lapho i-hardware izodlala khona imidiya yokuqala futhi "ithathe" okuqukethwe kwayo bese ikuguqula kube yifomethi yedijithali. Leli fayela elithunjiwe livame ukuthathwa ngekhwalithi ephezulu kakhulu njengoba kulindeleke ukuthi lidlule ezinqubweni ezahlukahlukene ezingase zehlise ikhwalithi. Ngakho-ke, kuhlale kufunwa ukubamba okuphezulu kakhulu.  Ukucindezela Ifayela ledijithali elibanjiwe livame ukuba likhulu kakhulu, lidinga inani elikhulu lesikhala sokugcina esidijithali futhi akunakwenzeka ukuliletha kumthengi ngezindlela zebhendi ebanzi. Ngakho-ke, kumelwe icindezelwe ngenqubo ebizwa ngokuthi ukufaka ikhodi noma ukuguqula ikhodi.  Kule nqubo, i-codec isetshenziselwa ukucindezela ifayela ledijithali elibanjwe libe yifomethi encane ngokwanele ukuthi ingahanjiswa kumsebenzisi wokugcina, imvamisa ngezindlela zebhendi ebanzi. Le nqubo yokufaka amakhodi ihilela ukucatshangelwa kwezinto eziningi eziguquguqukayo ngokuthi ifayela lizocindezelwa kanjani. Okwe-audio, lokhu kuvame ukuba ne-bit-rate kanye nesilinganiso sesampuli. Okunye okuguquguqukayo kwevidiyo kufaka phakathi isinqumo, isilinganiso sefreyimu futhi futhi ine-bit-rate yayo edinga ukucaciswa.  Lezi zinto eziguquguqukayo zinqunywa ukuthi ifayela elithile lizosetshenziswa kanjani; ukulanda, ukusakaza ku-PC, ukusakaza kudivayisi ephathekayo, njll.  Kodwa-ke, ikhwalithi ivame ukuba yinkinga kulesi sigaba futhi kunakekelwa kakhulu ukuqinisekisa ukuthi ikhwalithi yendawo ingeyekhwalithi ephezulu kakhulu ngendlela yayo yokulethwa ehlosiwe. Ngokwesibonelo, ividiyo efakwe ikhodi ukuze isakazwe kumadivayisi eselula idinga izinga eliphakeme kakhulu lokucindezelwa kunalokho obekungenzeka uma ilandwa kwi-PC, ngakho-ke ikhwalithi yevidiyo ngeke ibe yinhle kangako.  Ukulawulwa Kwekhwalithi Ukulawulwa kwekhwalithi kuyadingeka ukuze kuqinisekiswe ukuthi ifayela elifakwe ikhodi ngendlela efanele, linemiphumela efiselekayo futhi alinalo ukonakala. Izinga lapho ifayela lithathwa njengelamukelekayo lisuselwa kunoma yikuphi ukubonwa kweqembu elibhekene nokufaka ikhodi kokuqukethwe, noma indinganiso ethile echazwe ngumnikazi wokuqukethwe okumele iqembu elifaka ikhodi liyihloniphe.  Ukulawulwa kwekhwalithi akudingeki ukuba kwenzeke kuphela kulesi sikhathi. Iningi lezinkampani ezibhekene nenqubo yokuhlinzekwa kwedijithali zizobeka abezindaba ngaphansi kokuhlolwa kwenqubo yokulawulwa kwekhwalithi ezigabeni ezahlukahlukene kufaka phakathi: ukutholwa kwasekuqaleni, ngemuva kokucindezelwa, ngemuva kokungeniswa kanye nokushicilelwa ngemuva kokushicilelwa, ngaleyo ndlela kuqinisekiswe ukuthi abezindaba abakonakalanga noma abawohlokanga ngokungadingekile kunoma yisiphi isigaba senqubo yokuhlinzekwa kwedijithali.  Ukuphathwa Kwempahla Yedijithali Isistimu yokuphathwa kwempahla yedijithali iphatha imethadatha, okuqukethwe kanye nempahla ehlobene nayo efana nesembozo se-albhamu nomdwebo wephosta yama-movie. Imvamisa yizinhlelo zokuphathwa kwempahla yedijithali ezisingatha nokushicilelwa kokuqukethwe uqobo ku-digital storefront. Ezinye izinhlelo zokuphathwa kwempahla yedijithali ezakhelwe ngqo uchungechunge lokuthengiswa kwedijithali kanye nokulethwa kwemidiya ye-elekthronikhi kuzolandelela inqubekela phambili yokuqukethwe njengoba kudlula uchungechunge lokuthengiswa kwedijithali. Uhlelo oluhle lokuphathwa kwezimpahla zedijithali kufanele futhi luhlanganise amathuluzi okubika angakwazi ukubuyisa isimo sezici ezahlukahlukene zochungechunge lokuhlinzekwa kwedijithali uqobo.  Ukufakwa Kwemethadatha I-metadata iwulwazi olukhomba futhi luchaze okuqukethwe okuqukethwe. Lolu lwazi lungabandakanya ulwazi oluthile lwezindaba ezifana: Isihloko, umculi, inkampani yokukhiqiza, incazelo yesizini / isiqephu, usuku lokukhishwa kwasekuqaleni, njll. I-metadata ingabandakanya nolwazi oluhlobene nebhizinisi olufana: amanani nokutholakala.  Ukuphathwa Kwamalungelo Ezedijithali Isici esibalulekile sokuhlinzekwa kwedijithali inqubo yokubethela okuqukethwe ukuze kungadlalwa ngaphandle kwelayisense elifanele elivame ukutholakala ngokuthenga okuqukethwe noma ukubhalisa. Lokhu kunciphisa amathuba okuba abezindaba baphucwe izincwadi.  Ukungenisa Ukungenisa yisigaba lapho ifayela elicindezelwe nemethadatha kufakwa khona ohlelweni lokuphathwa kwempahla yedijithali. Akudingekile ukuthi i-metadata nefayela lemidiya elicindezelwe lifakwe ohlelweni ngasikhathi sinye, noma kunjalo, kuzoba khona iphuzu kwinqubo lapho bobabili befakwe ohlelweni futhi i-metadata ingabhekisa kufayela lemidiya.  Inethiwekhi Yokuletha Okuqukethwe Lapho amafayela abezindaba edliwa, agcinwa futhi ahanjiswe ngenethiwekhi yokulethwa kokuqukethwe (i-CDN) ekwazi ukuletha abezindaba kumsebenzisi wokugcina. I-CDN kufanele ikwazi ukusekela inani elilindelekile labathengi.  Umthengisi/Umthengisi Wezitolo/Umthengisi Wezinhlelo Zedijithali/Umhlinzeki Wezinsizakalo Zedijithali Okuqukethwe ekugcineni kuzoboniswa esitolo esidijithali lapho umthengi angabuka khona uhlu lwekhathalogi lokuqukethwe futhi afinyelele kokuqukethwe ngokuthenga, ukubhalisa noma enye indlela umthengisi akhethe ukuyenza itholakale.
