Ifomathi ye-Blu-ray Disc kunye namaProfayili omdlali
Ukongeza kwisiseko se-Blu-ray Disc kunye neenkcukacha zeMdlali. Kukho "iiprofayili" ezintathu ezithengwa ngabathengi. Ezi profayile zibandakanya amandla abadlali be-Blu-ray Disc, kwaye ziye zaphunyezwa yi-Blu-ray Disc Association ngale ndlela:
- Iprofayile 1.0 - Le phrofayili ihlanganisa bonke abadlali be-Blu-ray abayenziwe ngaphambi koNovemba 2007. Abadlali kule candelo banomnye umyalezo wevidiyo kwaye akukho khompyutha. Oku kuthetha ukuba aba badlali abakwazi ukufikelela kwi-PIP (Ifoto-in-Picture) okufakwe ngaphakathi kwi-Blu-ray Discs, kwaye abanako ukufikelela kwi-Web-enabled enabled content ezifakwe kwii-Blu-ray Discs. Njengengxelo yecala, bonke abadlali be-HD-DVD kufuneka bafumane ezi zinto zakhiwe ukususela ngosuku olulodwa.
- Iphrofayli 1.1 - Le proferenti ifaka iprojekthi yecala ye-audio / yevidiyo kunye ne-256 MB yokugcinwa kwememori kuyo yonke imodeli yokudlala ye-Blu-ray eyenziwe emva komhla ka-1 kuNovemba 2007. Oku kuvumela ukufikelela kwimixholo yokuhlaziya i-PIP kunye nezinye izinto ezibandakanyekayo ezibandakanya kwi-Blu- iiDis Discs (ezibizwa ngokuba yi "Bonus View"). Ezinye iipalenti 1.1 abadlali nabo bavumela ukufikelela ngokuthe ngqo kwi-web-available firmware upgrades. Nangona kunjalo, akudingeki ukuba umdlali we-Blu-ray Disc ane-intanethi yoxhumo lwe-intanethi ukuze afaneleke njengomdlali ofanelekileyo weProfayli 1.1.
- Iprofayile 2.0 - Le phrofayili ibhekiselwa kuyo ngokuthi "BD-Live". Kufana neProfayili 1.1, kodwa idibanisa amandla okugcina imemori ye-1GB kwaye ifuna ukuba kufakwe uxhumano lwe-Ethernet, olwenza kube lula ukulungelelanisa ukufumana iimpawu ezongezelelweyo ezingabandakanywa kwii-Blu-ray Discs kunye nolwazi oluninzi olufikelelekayo lwe-intanethi ngokufikelela kwi-intanethi yesantya esiphezulu. Oku kuzisa ifom ye-Blu-ray Disc kwindawo efanayo neye-HD-DVD abadlali bevela ekuqalisweni kokuqala kwefomathi yangoku-ntlawulo.
Injongo kukuba yonke i-Blu-ray Discs, kungakhathaliseki ukuba yiProfayili ababophelelwe kuyo, iya kudlalwa kuwo wonke umdlali we-Blu-ray Disc. Nangona kunjalo, nayiphi na into ekhethekileyo yediskiti efuna iProfayili 1.1 okanye i-2.0 ayiyi kufumaneka kumaqela abaProfayili 1.0, kunye neProfayili 2.0 umxholo othize awuyi kufumaneka yiProfayili 1.0 okanye 1.1 umdlali oxhobileyo.
Ngakolunye uhlangothi, abanye abadlali beProfayili 1.1 bangaba yi-firmware kunye nokukhutshwa kwememori (ngokusebenzisa i-flash flash yangaphandle), ukuba ngaba sele benesidityaniso se-ethernet kunye noxhumano lokufakelwa kwe-USB, ngoxa i-Sony Playstation 3 Blu-ray ifakwe ikhonsoli yemidlalo ingahlaziywa kwiProfayili. 2.0 kunye nokuphuculwa kwe-firmware yokuphucula.
QAPHELA: Ifomati ye-HD-DVD ayilwanga yinkqubo yeprofile. Bonke abadlali be-HD-DVD abaye bakhululwa, kwaze kwaba yilapho beyeke ukuyeka kwabo, ukusuka kwixabiso elincinci, ukuya kumaxabiso abizayo, abasebenzisi abavumelekile ukuba bafikelele kuzo zonke iinkqubo ezisebenzayo kunye ne-intanethi ezihambelana ne-HD-DVD ezibandakanya ezo zinto.
