Amakhodekhi evidiyo abelokhu ehlala njalo kusukela ekufikeni kwamakhompiyutha kanye nekhono lawo le-multimedia lokudlala amafayela evidiyo. Impela nina enivele nixoxa nge-PC ngeminyaka yama-90s, uzobe ujwayelene nabo bonke abaye bavela kuze kube namuhla, ngaleso sikhathi sase sibhebhana Izinqumo ze-8K kanye ne-10K yethelevishini. Kodwa, ingabe ukhona umehluko phakathi kwezimbili ezidume kakhulu esinazo namuhla?
Amakhodekhi amabili okubusa wonke
Impela asisho into entsha ongayazi uma siqinisekisa lokho i-codec ye-H.264 idume kakhulu esingayithola manje Okufanayo cishe kunoma yikuphi okuqukethwe esikuguqulayo noma esikudalayo ukuze kudlale kukhompuyutha, iselula, ithebhulethi nanoma yini. Kungakhathaliseki ukuthi usebenzisa luphi uhlelo, ngokuqinisekile uzothekelisa ifayela le-.mp4 nge-codec ye-H.264. Lokhu kungenxa yokuthi iyifomethi egxile kakhulu encazelweni ephezulu futhi ekwazi ukusebenza nanoma yiluphi uhlobo lwehadiwe ku-HD, i-FullHD (1080p) noma i-4K izinqumo futhi ayithathi umkhawulokudonsa omningi lapho kusakazwa.
Manje, cishe eminyakeni eyishumi edlule, okwakuzoba (futhi sicabanga ukuthi kuzoqhubeka kube) kwavela umlandeli wakhe, I-H.265, eyaziwa nangokuthi i-HEVC noma Ukufakwa Kwekhodi Ngevidiyo Esebenza Kakhulu nokuthi ayisebenzi kahle kuphela ku-HD, i-FullHD (1080p) nezinqumo ze-4K, kodwa naku-8 naku-10K, okuqinisekisa amandla okucindezela angafinyelela ku-50% we-H.264 izikhathi eziningi. Isibonelo, imuvi engu-4,3GB ngefomethi ye-DVD ingayishiya kumamegabhayithi angu-650 kuphela, uma kuqhathaniswa namagigabhayithi angaphezu kweyodwa ku-H.264.
Okusho ukuthi, ngezinga le-H.265 singadlala isiginali ye-8K ebukhoma kudivayisi yeselula enoxhumo olujwayelekile lwe-inthanethi, Ayisheshi kakhulu, yingakho, njengoba ungacabanga, isiphenduke indlela engcono kakhulu yokwandisa amafomethi wevidiyo maduze nje.
Kungani sisasebenzisa i-H.264?
Nokho, kukhona okumele kuhlukanise amafomethi amabili ukuze i-H.264 iqhubeke nokusetshenziswa ngaphezulu kwe-H.265 uma okwesibili sizothola isigamu sefayela esindayo futhi ezikhathini eziningi, ngekhwalithi ethe xaxa nokwethembeka kokwasekuqaleni. Futhi impendulo kufanele itholakale ku-hardware edingekayo ukuze wenze ngokushesha umsebenzi wokunciphisa leyo vidiyo bese uyidlala.
Ngakho-ke, kulula ku-hardware (eshibhile) yedivayisi yokudlala ividiyo ukuthi ikwazi ukusebenza ngefayela ku-H.264 kunenye eku-H.265, okudinga amandla amaningi okucubungula ukwenza umsebenzi. lokho kuzosibonisa esikrinini. uma ukhumbula, Kwenzeka into efana nalena kithi ngenkathi ifomethi ye-.mkv isakazeka, ukuthi bekungenzeki ukuyethula kunoma iyiphi ikhompuyutha noma umakhalekhukhwini. Kwakudingeka amandla amaningi okucubungula kunama-a .avi noma izinto ezifanayo kusukela ngesikhathi esifanayo.
Ukuqalisa ividiyo ngo-H.265 kudinga lawo mandla engeziwe okuyinto, okwamanje, imakethe ayikuceli ngoba nge-H.264 sinokungaphezu kokwanele: ayithathi isikhala esiningi noma umkhawulokudonsa, ngisho nokuqukethwe kwe-4K, ilawuleka cishe nge-100% yamadivayisi amanje futhi igcina inhlonipho eyikhwalithi kokwasekuqaleni. Enye into kuzoba lapho sidinga ukugxumela ku-8K, noma ku-10K bese, yebo, leso sikhala esincane esithatha ngenxa yokucindezelwa okukhulu, kanye nokuthuthuka kwehardware edingekayo kuzo zonke izindawo (omakhalekhukhwini, amaphilisi, isethi. -top box, njll.), yenza ukunwetshwa kwaleyo H.265 kugcwaliseke.
