Uma i-Android TV yakho, i-Mi Box, i-TV Box eshibhile, noma ngisho nefoni yakho isakaza i-Netflix, i-Disney+, noma i-Prime Video kuphela ngekhwalithi ephansi, njenge-DVD edabukile kabi, inkinga cishe inegama: i-Widevine kanye ne-switch ye-L1 kuya ku-L3 eyesabekayo . Into ekhungathekisayo ukuthi ngezinye izikhathi awukashintshi lutho; idivayisi ithi isekela i-HD noma i-4K, kodwa izinhlelo zokusebenza zokusakaza zinamathele ku-SD noma zenza amaphutha angajwayelekile.
Lokhu kuziphatha akuyona inkinga elula noma into exakile ye-Netflix: kuhlobene ngqo nendlela i-Google ephatha ngayo i-Widevine CDM DRM ku-Android naku-Android TV , kanye nendlela ipulatifomu ngayinye (i-Netflix, i-Disney+, i-DigiTV, njll.) esabela ngayo lapho ithola izinga lokuphepha elinganele. Ukuqonda ukuthi iyini i-Widevine, ukuthi amazinga ayo asho ukuthini, ukuthi kungani kuvela amaphutha afana ne-NW-6-404, nokuthi yini ongayenza ku-Android TV nakumadivayisi eselula ukuzama ukuyilungisa kubalulekile ekubuyiseleni i-HD ne-4K ngaphandle kokuhlanya.
Iyini i-Widevine futhi kungani inquma ikhwalithi ku-Android TV?
I-Widevine uhlelo lokuphathwa kwamalungelo edijithali (i-DRM) oluphethwe yi-Google olusetshenziselwa ukuvikela okuqukethwe kwevidiyo ekubanjweni kwezithombe. Akuyona i-Android TV kuphela: ikhona nakumafoni e-Android, iziphequluli (i-Chrome, i-Edge, njll.), ama-Smart TV amaningi, ama-game consoles, amadivayisi okusakaza asemthethweni, futhi, ngama-SDK, ngisho naku-iOS.
Umqondo ulula: uma uvula i-Netflix, i-Disney+, noma i-Prime Video, uhlelo lokusebenza ludinga ukuqinisekisa ukuthi idivayisi iphephile ngokwanele ukuyivumela ukuthi idlale ividiyo ku-HD, i-Full HD, noma i-4K . Ukuze yenze lokhu, ithembele ku-Widevine CDM (Content Decryption Module), okuyiyona ngxenye ephethe ukubethela, ukususa ukubethela, nokuphatha okhiye bokuqukethwe okuvikelwe.
I-Widevine isebenzisa amazinga ahlukene okuphepha (L1, L2, kanye ne-L3) achaza izinga iprosesa kanye nendawo ephephile yedivayisi (TEE) ezihileleke ngalo ekuvikeleni ividiyo. Uma izinga liphezulu, amapulatifomu aqiniseka kakhulu ekuvuleni izinqumo eziphakeme. Uma izinga lehla, izinhlelo zokusebenza zisabela ngokubeka umkhawulo wekhwalithi noma ngisho nokuvimba ukudlala.
Umehluko phakathi kwe-Widevine L1, L2 kanye ne-L3 nokuthi iyithinta kanjani i-Netflix
Empeleni, kumafoni e-Android TV kanye ne-Android uzobona amazinga amabili kuphela: i-Widevine L1 kanye ne-Widevine L3 . I-L2 ikhona, kodwa ayisetshenziswa kakhulu emakethe yabathengi. Umehluko phakathi kwe-L1 ne-L3 yilokho okunquma ukuthi uzobona isithombe esihle se-4K noma esifiphele.
Uma idivayisi ine- Widevine L1 , ukuqaqwa kwevidiyo kwenzeka ngaphakathi kwe-Trusted Execution Environment (TEE), indawo ephephile exhunywe ku-processor kanye nezingxenye ezizinikele. Lokhu kusho ukuthi okhiye kanye nokusakazwa kwevidiyo kuvikelwe kahle, ngakho-ke izinsizakalo ezifana ne-Netflix noma i-Disney+ zivumela ukudlalwa kwe- HD (720p), i-Full HD (1080p), kanye ne-4K HDR , uma nje uhlelo lokubonisa kanye nokubhalisa luyisekela.
Uma idivayisi ine- Widevine L3 kuphela , ukubethela akwenzeki ngaphakathi kwehadiwe evikelekile, kodwa endaweni evamile ye-Android. Kubahlinzeki bokuqukethwe, lokhu kubeka ingozi, ngakho-ke basabela ngokukhawulela ukudlala ekuchazeni okujwayelekile (SD, 480p/540p) . Lesi yisimo esivamile lapho, kufoni ephathekayo enesikrini se-Full HD noma ithelevishini ye-4K, i-Netflix ibonakala inombala ogqamile kakhulu kunokujwayelekile.
Enye imininingwane edida abantu abaningi ukuthi i-YouTube ayinciki ku-Widevine ngendlela efanayo ngokuqukethwe kwayo okuningi kwamahhala, ngakho-ke isengakhipha i-1080p noma i-4K ngisho nakumadivayisi lapho i-Netflix noma i-Disney+ ikhawulelwe ku-SD. Lokhu kuchaza lawo macala lapho i-YouTube ibukeka iphelele ku-Android TV, kodwa i-Netflix ibukeka sengathi yaqoshwa ngocingo oludala.
Izibonelo ezijwayelekile: I-Mi Box, i-Android TV, omakhalekhukhwini baseShayina nama-TV Box
Elinye lamacala okukhulunywa kakhulu ngawo yilelo lesizukulwane sokuqala se-Mi Box S ene-Android TV . Abasebenzisi abaningi baqinisekisile ngezinhlelo zokusebenza ezifana ne-DRM Info ukuthi i-Mi Box yabo ivela njenge-Widevine L1, kodwa-ke uma befinyelela i-Netflix, okuqukethwe kudlala kuphela ku-SD. Okwenza izinto zibe zimbi kakhulu, kuleyo Mi Box efanayo, i-Prime Video kanye ne-YouTube output HD ngaphandle kwezinkinga , okwenza kucace ukuthi inkinga iqondene ne-Netflix nokuthi ihumusha kanjani isitifiketi saleyo divayisi.
Kuye kwabonakala izimo ezifanayo kumafoni e-Android. Amanye amamodeli e-Google Pixel 5 kanye nawangaphambilini ahlukunyezwe yi-Widevine ngokuzumayo esuka ku-L1 aya ku-L3 ngemva kokushintshashintsha okuthile kokuphepha (ngoFebhuwari, ngoMashi, nango-Ephreli 2021). Naphezu kokuqinisekiswa ngokusemthethweni kwe-HD kanye ne-HDR ku-Netflix, uhlelo lokusebenza lubavumele kuphela ukudlala ku-SD, futhi esigabeni sokucaciswa kokudlala, bavele njengamadivayisi e-L3.
Ezweni lamabhokisi e-TV ashibhile, ikakhulukazi lawo athengiswa njenge-"Android TV" kodwa empeleni angamabhokisi e-TV aseShayina angenazo iziqinisekiso ezisemthethweni , inkinga inamandla kakhulu: amaningi aqale ukukhombisa iphutha le-NW-6-404 ku-Netflix , okusho ukuthi uhlelo lokusebenza lubheka idivayisi njengengafanele futhi luvimba ukufinyelela kukhathalogi, yize lonke uhlelo lungakhipha i-4K ngaphandle kwenkinga.
Kuyafaneleka futhi ukukhuluma ngezinkinga amanye amafoni e-Xiaomi, Redmi, kanye ne-POCO abhekana nazo ngemva kokubuyekeza i-MIUI noma i-HyperOS: uhlelo lwehlisa i-Widevine kusuka ku-L1 kuya ku-L3, ngakho-ke i-Netflix, i-Disney+, kanye ne-Prime Video ziyeke ukubonisa i-HD noma i-4K yize umsebenzisi engakashintshi lutho. Isikrini singase sibe sihle kakhulu, uxhumano lwe-fiber luphelele… kodwa i-DRM ilawula indawo.
Inkinga ye-Google Pixel Widevine L3
Kwenzeke isigameko esibi kakhulu kumafoni e-Pixel: ngemva kokushintshashintsha kokuphepha ngo-2021, abasebenzisi abaningana baqala ukubona izinga labo le-Widevine lehla lisuka ku-L1 laya ku-L3 ngaphandle kwesizathu esibonakalayo. Babevula i-Netflix, bahlole Izilungiselelo Zohlelo Lokusebenza > Ukucaciswa Kokudlala, bese bethola ukuthi idivayisi yabo ikhawulelwe ku-L3, okunciphisa ngempumelelo ikhwalithi ibe yi-SD.
Into ekhungathekisa kakhulu ukuthi ukusetha kabusha kwasefekthri, ukusula i-cache, ukukhanyisa izithombe ezihlanzekile zasefekthri, noma ukufaka kabusha i-Netflix akuzange kulungise lutho, ngoba inkinga yayikukuthi uhlelo luphatha kanjani okhiye be-Widevine nokuthi yiluphi ulwazi oluthunyelwe kwezinye izinhlelo zokusebenza. I-Google yaze yavuma ukuthi iyazazi iphutha futhi yayisebenza esixazululweni, futhi yaxwayisa nokuthi lokhu kungathinta hhayi amafoni e-Pixel kuphela, kodwa namafoni avela kwabanye abakhiqizi.
Okwamanje, abanye abasebenzisi bathole izindlela ezingavamile zokubuyisa i-L1. Belandela iziqondiso ezivela kumaforamu afana ne-droidwin.com, abanye bazama ukukhubaza nokuvuselela ukuqinisekiswa kwe-biometric ku-Google Play Store , basula i-cache kanye nesitoreji sezinhlelo zokusebenza ze-Play Store kanye ne-Netflix, futhi bangena ngemvume kuhlelo lokusebenza. Kwezinye izimo, ngemva kokwenza lezi zinyathelo nokuphoqa ukuxoxisana kwelayisense entsha, i-DRM Info ibonise i-L1 futhi, futhi i-Netflix ivule i-HD.
Abanye bathi ukubhalisa ku- beta ye-Android 12L, ukubuyekeza nge-OTA, bese bebuyela enguqulweni eqinile kugcina isimo sabo se-L1 tier. Abasebenzisi be-Pixel 4 XL kanye ne-Pixel 5 babike ukuthi ngemuva kokulandela lo mjikelezo (ukujoyina i-beta, ukuthola isibuyekezo se-OTA, nokubuyela egatsheni elizinzile), i-Netflix yaqhubeka nokuqaphela amadivayisi ayo njenge-L1. Nakuba kungekho ncazelo yomphakathi egcwele imininingwane, kubonakala sengathi amanye ama-beta ayefaka ama-patches e-DRM aqhubeka ngemva kokushintsha kwe-beta.
I-Widevine L3 iyithinta kanjani i-Netflix, i-DigiTV, i-Disney+, namanye amapulatifomu?
Uma idivayisi inamathele ku- Widevine L3 , imiphumela ibonakala cishe kunoma iyiphi isevisi edinga izinga eliphezulu lokuphepha. Ku-Netflix, ungaqhubeka nokudlala okuqukethwe, kodwa kuphela ngencazelo ejwayelekile . Ayikho i-HD futhi ngokuqinisekile ayikho i-4K, kungakhathaliseki ukuthi ihadiwe yakho inamandla kangakanani.
Ngezinye izinhlelo zokusebenza, ukuziphatha kungaba nomkhawulo nakakhulu. Isibonelo, kube nezimo zabasebenzisi abanamafoni eselula asezingeni eliphansi noma amabhokisi e-TV angenaso isitifiketi lapho uhlelo lokusebenza lwe-DigiTV lungavumeli ngisho nokudlala i-SD . Usekelo lobuchwepheshe luhlola izinga le-Widevine kusetshenziswa i-DRM Info, lubone ukuthi idivayisi iku-L3, futhi luyibheka ngokuqondile njengengahambisani, luvimbele ukufinyelela eziteshini.
Umhlinzeki ngamunye uchaza izinqubomgomo zakhe ze-DRM : ezinye, njengeNetflix, zibekezelela i-L3 ngokushintshana nesisombululo esincishisiwe, kanti ezinye zidinga i-L1 ngisho nokuqukethwe kwe-SD. Kukhona futhi umehluko phakathi kokukhawulela isinqumo nokuvimba ukudlala ngokuphelele: I-Netflix ivame ukuqhubeka isebenza, kodwa ngekhwalithi encishisiwe, kuyilapho ezinye izinhlelo zokusebenza ze-IPTV noma ze-opharetha zingase zenqabe ukuqalisa.
Isiphithiphithi seWidevine kuXiaomi, Redmi kanye nePOCO
Kuhlelo lwe-Xiaomi, iRedmi, kanye ne-POCO, abasebenzisi abaningi bathole ukuthi ngemuva kokubuyekezela enguqulweni entsha ye -MIUI noma i-HyperOS , amafoni abo alahlekelwe ikhono lokudlala okuqukethwe kwe-HD noma kwe-4K kumasevisi okusakaza. Iphethini ivame ukufana: konke kusebenze kahle ngaphambili, kodwa ngemuva kokubuyekezwa kwe-OTA, i-Netflix, i-Disney+, noma i-Prime Video ibukeka imbi kakhulu.
Imbangela imvamisa ukonakala noma ukungavumelanisi kwezitifiketi zokuphepha ze-Widevine . Ngemva kokubuyekezwa okuthile okungasetshenziswanga kahle, okhiye abasetshenziswa uhlelo ukufakazela ukuthi indawo iphephile baba abavumelekile noma ababikwa kahle. Amapulatifomu okusakaza, angasaboni izimo ezithembekile, ehlisa idivayisi ibe yi-L3 futhi asebenze ukuvimba kwe-HD.
Into ecasulayo ukuthi ngokuvamile asikho isixwayiso esicacile. Ikhwalithi imane yehle, futhi abasebenzisi abaningi basola uxhumano noma uhlelo lokusebenza uqobo . Kuphela ngokuhlola i-DRM Info kanye nemininingwane yokudlala ku-Netflix lapho kutholakale khona ukuthi impande yenkinga yi-Widevine.
Izindaba ezinhle ukuthi, kumamodeli amaningi akamuva e-Xiaomi, POCO, kanye ne-Redmi, leli phutha alihlali njalo, futhi kungenzeka ukubuyisela isitifiketi se-L1 ngaphandle kokucushwa kwezimpande noma ukukhanyisa ama-ROM enziwe ngokwezifiso . Kodwa-ke, lokhu kuncike ekutheni umenzi uvumele yini inketho ehambisanayo kuzilungiselelo zesistimu.
Indlela yokuhlola ukuthi idivayisi yakho ine-Widevine L1 noma i-L3
Ngaphambi kokuthi uqale ukususa izinto ngokunganaki, kuwukuhlakanipha ukuhlola ukuthi inkinga ibangelwe yi-Widevine. Indlela elula yokwenza lokhu ukufaka uhlelo lokusebenza lwe-DRM Info oluvela ku-Google Play , olubonisa lonke ulwazi mayelana namamojula e-DRM edivayisi.
Uma usuyivulile, skrolela phansi uye esigabeni se -Google Widevine bese ubheka insimu ethi "Izinga Lokuphepha". Amanani abalulekile yile:
- L1: izinga eliphezulu lokuphepha, livumela i-HD, i-Full HD kanye ne-4K uma ihadiwe kanye nohlelo lokusebenza kuyisekela.
- L2: izinga eliphakathi nendawo, elingavamile kumaselula entengiso kanye nama-TV e-Android.
- L3: izinga eliphansi, ngokuvamile livumela i-SD kuphela futhi, kwezinye izinsizakalo, alivumeli ngisho nokudlala.
Uma idivayisi yakho ibonisa i-L3 futhi ubhekene nekhwalithi ephansi noma amaphutha , usuvele ubonile umthombo wenkinga. Kodwa-ke, uma i-DRM Info ibonisa i-L1 kodwa i-Netflix iqhubeka nokunciphisa isisombululo, ungase ubhekane nenkinga yokuqinisekiswa ethize kulolo hlelo lokusebenza noma iphutha kumaseva ayo okunikeza amalayisense.
Esimweni esithile seNetflix, ungaya naku- App Settings > Playback Specification ukuze ubone ukuthi yiliphi izinga le-DRM elilitholayo nokuthi yiliphi ikhwalithi ephezulu evunyelwe. Lena indlela enhle yokuqinisekisa ukuthi uhlelo lokusebenza lufunda kahle izinga lakho le-Widevine noma kukhona okungahambi kahle.
Izindlela zokuzama ukubuyisa i-Widevine L1 ku-Xiaomi, POCO kanye ne-Redmi
Kumafoni amaningi e-Xiaomi, POCO, kanye ne-Redmi alahlekelwe yisitifiketi sawo se-HD ngemuva kokubuyekezwa, kunenketho elula yokulanda kabusha noma ukubuyisela isitifiketi se-L1 ngaphakathi kwezilungiselelo zesistimu. Indlela eqondile iyahlukahluka kuye ngenguqulo ye-MIUI/HyperOS kanye nemodeli, kodwa ngokuvamile ilandela inqubo efanayo.
Ngokuvamile udinga ukuya kuzilungiselelo ezihlobene neminwe, ukuqashelwa kobuso, kanye nokukhiya isikrini bese ubheka isigaba esixhunywe ekukhokheni kweminwe noma ukuphepha okwengeziwe. Ngaphakathi kwaleyo menyu, amanye amadivayisi anokufakwa okuthile kwe-Widevine (L1) okukuvumela ukuthi uvuselele, uqinisekise kabusha, noma ubuyisele isitifiketi. Ngemva kokuthepha leyo nketho bese uqala kabusha idivayisi, i-DRM Info izophinde ibonise i-L1, futhi izinhlelo zokusebenza zevidiyo zizophinde ziphinde zidlale i-HD.
Njengesinyathelo esengeziwe, kuyalulekwa ukusula idatha kanye nenqolobane yezinhlelo zokusebenza zokusakaza eziyinkinga . Isibonelo, ku-Netflix ku-Android, ungaya kuzilungiselelo > Izinhlelo zokusebenza > i-Netflix > Isitoreji, bese uthepha ku-clear data/clear cache. Lokhu kuphoqa uhlelo lokusebenza ukuthi luxoxisane ngamalayisense neseva futhi lubhalise kabusha idivayisi uma uhlelo selunesitifiketi se-Widevine L1 ngokulandelana.
Uma, ngemva kokubuyisela isitifiketi nokusula idatha, idivayisi isabonakala njenge-L3, inkinga ingase ibe senguqulweni ye-MIUI noma ye-HyperOS uqobo futhi ingalungiswa kuphela ngesibuyekezo se-OTA esizayo noma ngokukhanyisa enye i-firmware esemthethweni . Kulezi zimo, ngaphandle kokuthi ujwayelene kakhulu nenqubo yokukhanyisa, kungcono ukulinda izibuyekezo bese ulandela izinkundla ezisemthethweni zomenzi.
I-bootloader evuliwe, ama-ROM enziwe ngokwezifiso, kanye nokulahlekelwa unomphela kwe-L1
Esinye isimo esivame kakhulu phakathi kwabasebenzisi abathuthukile yileso salabo abavula i-bootloader ukuze bafake ama-ROM enziwe ngokwezifiso noma benze izinguquko zesistimu. Kumadivayisi amaningi (ikakhulukazi amamodeli amadala e-Xiaomi), ngokushesha nje lapho uchungechunge olusemthethweni lokwethenjwa seluphukile, idivayisi ayisabhekwa njengeqinisekisiwe ngokugcwele futhi i-Widevine yehliselwa ku-L3 cishe ngokushesha.
Ngaphezu kokulahlekelwa yi-L1 ne-HD ku-Netflix noma ku-Disney+, lolu shintsho lungabangela ukuthi ezinye izinhlelo zokusebenza ezibucayi, njengezinhlelo zokusebenza zasebhange noma ama-wallet e-cryptocurrency, ziyeke ukusebenza noma zibonise izixwayiso zokuthi imvelo ayiphephile. Ngisho noma kuphasiswa izinyathelo zokuphepha ze-SafetyNet noma ezifanayo, i-DRM ingase isakubheka njengendawo engathembekile.
Kulezi zimo, ukulungisa izilungiselelo noma ukususa ama-cache ngokuvamile akusizi: uma nje i -bootloader isavuliwe, uhlelo ngeke lubheke idivayisi njengephephile ngokwanele kwi-Widevine L1 . Isixazululo esithembekile kuphela ukubuyela ku-ROM yesitoko bese uvula kabusha i-bootloader.
Endabeni ye-Xiaomi, lokhu kuhilela ukulanda i -ROM esemthethweni yemodeli kuwebhusayithi ye-Xiaomi Community , ukufaka ifoni kwimodi ye-fastboot, ukuyixhuma kwi-PC, nokusebenzisa ithuluzi elifana ne-OS ROM Flashing Tool / MiFlash ukufaka kabusha i-firmware yokuqala. Uma inqubo yokukhanyisa isiqediwe futhi i-bootloader ikhiyiwe futhi, i-Widevine L1 izobuyiselwa kumamodeli amaningi, uma nje isekelwa umenzi.
Amabhokisi e-TV aseShayina, iphutha le-NW-6-404, kanye namalayisense e-Netflix
Amabhokisi e-Android TV ashibhile abhekane nenkinga yangempela selokhu iNetflix yaqinisa izidingo zayo zokuqinisekisa . Abasebenzisi abaningi bahlangabezane, cishe ngobusuku obubodwa, nephutha le-NW-6-404 lapho bezama ukuvula i-Netflix, okwaholela esikrinini esimnyama futhi kungabikho ukufinyelela kukhathalogi.
Umsuka wenkinga ukuthi iNetflix ayidingi nje kuphela i-Widevine L1 ezingeni lehadiwe , kodwa futhi nokuthi idivayisi ifakwe ohlwini lwamadivayisi aqinisekisiwe nokuthi umenzi ukhokhele futhi wahlangabezana nezimo ezithile zobuchwepheshe. Sekuyiminyaka eminingi, abakhiqizi abaningi bebhokisi lethelevishini laseShayina bebethembele kumalayisense angekho emthethweni noma aphethwe kabi, futhi lapho iNetflix iqeda ukuxhaswa ngemali, la madivayisi ayeshiywa ngaphandle komdlalo.
Ngisho noma imininingwane ibhalwe ohlwini oluthi "4K" noma "HDR" futhi i-chip isekela i-Widevine L1 ngokwethiyori, uma umenzi engakatholi (noma engakakhokhi) isitifiketi esisemthethweni se-Netflix , uhlelo lokusebenza luzovimba ukufinyelela futhi lubonise amaphutha afana ne-NW-6-404. Empeleni, kumsebenzisi wokugcina, lokhu kuyisikhiya esihlala njalo: kungakhathaliseki ukuthi ubuyekeza kangaki i-APK, iseva ye-Netflix izoqhubeka nokubona idivayisi engagunyaziwe.
Inketho ethembekile kuphela kulabo abathembele kakhulu kwiNetflix ukuthenga idivayisi ye-Android TV eqinisekiswe ngokusemthethweni noma i-Smart TV (i-Chromecast ene-Google TV, i-Nvidia Shield, amabhokisi e-TV avela kumikhiqizo emikhulu, ama-Smart TV athile, njll.). Kuze kube yilapho umenzi webhokisi le-TV elishibhile ethola ilayisensi edingekayo, akukho nkohliso yesimangaliso ezoqinisekisa ukusakazwa okuzinzile kwe-HD kanye ne-4K.
Izixazululo ezingaphelele ze-Netflix kumadivayisi angaqinisekisiwe
Noma kunjalo, abanye abasebenzisi bathole izindlela ezingaphelele zokuqhubeka nokusebenzisa i-Netflix kuma-TV box angaqinisekisiwe, yize cishe njalo kunemikhawulo ebalulekile futhi kungekho siqinisekiso sokuhambisana kwesikhathi esizayo . Elinye lamaqhinga okukhulunywe ngawo lihilela ukukhipha inguqulo yamanje ye-Netflix, ukusula i-cache nedatha, nokufaka i -Netflix APK eyenzelwe enye idivayisi eqinisekisiwe , njengamathebhulethi athile e-Samsung, nge-USB flash drive.
Kwamanye amamodeli athile, le nguqulo "ehlukile" ivumele abasebenzisi ukuthi bangene futhi badlale okuqukethwe , noma ngabe isikhombimsebenzisi silungiselelwe izikrini zokuthinta hhayi izilawuli ezikude. Kodwa-ke, lezi zixazululo zincike ezinguqulweni ezithile zohlelo lokusebenza futhi zingase ziyeke ukusebenza lapho iNetflix ishintsha inqubo yayo yokuqinisekisa.
Kuye kwabonwa nezindlela ezinolaka kakhulu, njengokushintsha uhlelo lokusebenza lwe-Netflix noma amafayela esistimu ukuze kuzanywe ukugwema ukuhlolwa kokuhambisana ngokwengxenye. Lezi zindlela zivame ukungazinzile, zingaphula imigomo yesevisi yesevisi, futhi azivamile ukubuyisela i-HD ngokuphelele. Ngokuvamile zivumela kuphela ukubukwa okuqhubekayo ku-SD noma ukusebenza isikhathi esilinganiselwe.
I-Widevine ne-iOS: kungani abaningi begcina bebalekele e-FairPlay
Nakuba iningi lezinkinga zekhanda ze-Widevine ligxile ku-Android TV, ama-TV Boxes, kanye namafoni e-Android, kunemibuzo mayelana nendima yayo ohlelweni lwe-iOS . I-Apple isungula i-DRM yayo, i-FairPlay, kanye ne-iOS ayisekeli ngokwendabuko i-combo ejwayelekile ye-Widevine (DASH + CENC), ngakho ukuhlanganiswa akulula kangako.
Ukuze kunqotshwe lo mehluko, i-Widevine inikeza i -iOS SDK ezinikele evumela abathuthukisi ukuthi bahlanganise i-DRM yayo kuzinhlelo zokusebenza ze-iPhone ne-iPad. Le SDK idlulisela okuqukethwe kusuka ku-DASH kuya ku-HLS ngokushesha, igcina okuqukethwe kuvikelwe ngelayibrari ye-CDM dynamic. Okunye kwalokhu kucubungula kwenziwa ohlangothini lweklayenti (ngaphakathi kohlelo lokusebenza ngokwalo), uma nje izinqubomgomo zokuphepha ze-Apple zihlonishwa.
Nokho, empeleni, amapulatifomu amakhulu avame ukukhetha i -FairPlay njenge-DRM yawo eyinhloko ku-iOS, ibhukha i-Widevine ye-Android, iziphequluli, nezinye izindawo . Le ndlela ehlanganisiwe inciphisa izinkinga zokuhambisana kwesikhathi eside. Akujwayelekile ukuthola abasebenzisi be-Android bekhathele yizinkinga ze-Widevine, behlisela ku-Layer 3, kanye neziphazamiso zesitifiketi, abagcina beshintshela ku-iOS befuna uchungechunge lwe-DRM olubikezeleka kalula, yize i-iOS nayo inemikhawulo yayo.
Lonke lolu daba lwe-Widevine, amazinga e-L1 kanye ne-L3, izitifiketi ze-Netflix, kanye namaphutha afana ne-NW-6-404 kwenza kucace ukuthi uma kukhulunywa ngokusakaza ku-Android TV noma kumadivayisi eselula, isikrini esihle kanye nokuxhumeka okuhle akwanele . Ukukhetha amadivayisi aqinisekisiwe kusukela ekuqaleni, ukuhlola izinga le-DRM nge-DRM Info lapho kukhona okungahambi kahle, ukubuyisela izitifiketi uma kungenzeka, nokugwema ukucushwa kwe-bootloader noma ama-ROM aphula uchungechunge lokwethembana ngokuvamile kuyindlela ethembekile kakhulu yokuqhubeka nokujabulela i-Netflix, i-Disney+, noma i-Prime Video ku-HD kanye ne-4K ngaphandle kwezimanga ezingathandeki. Yabelana ngalolu lwazi ukuze abasebenzisi abaningi bazi ngale nkinga.
