Kanye nekhwalithi ehlala ikhula yamavidiyo ama-smartphones anamuhla akwazi ukuwathwebula, isidingo senkumbulo sokuqoshwa siyanda. Isibonelo, ividiyo yomzuzu owodwa ekulungisweni kwe-4K ithatha u-350 MB. Yingakho, kusukela ngonyaka odlule, ifomethi entsha ye-HEVC noma i-H.265 yaqala ukusabalala kabanzi, i-Samsung manje eqale ukuyisekela, ikakhulukazi kumamodeli ayo akamuva aphezulu. Galaxy I-S9 ne-S9+.
I-HEVC (I-High Efficiency Video Coding) iyindinganiso yevidiyo yokuminyanisa enciphisa izinga ledatha phakathi, kodwa kuyilapho igcina ikhwalithi yesithombe efanayo ne-H.264 yangaphambilini. Yize ifomethi yavunywa emuva ngo-2013, abakhiqizi be-smartphone baqale ukuyisebenzisa ngonyaka odlule. Ube ngowokuqala ukuthatha isinqumo ngokusetshenziswa kwayo Apple, owethule njengengxenye yohlelo iOS 11. Manje abakwaSamsung sebejoyine inkampani yakwa-Apple, okuthi nakuba ingazange iziqhayise esidlangalaleni ngokusetshenziswa kwefomethi, kodwa ivumela ukuqoshwa kwamavidiyo ku-HEVC ngo. Galaxy I-S9 ne-S9+.
Nakuba ukurekhoda ku-HEVC kukhutshaziwe ngokuzenzakalela, abasebenzisi bangakwazi ukukunika amandla kalula. Vele uvule uhlelo lokusebenza Ikhamera, Iya ku Izilungiselelo (ngesithonjana segiya), khetha Ukulungiswa kwevidiyo futhi wenze kusebenze umsebenzi lapha ngokushintsha Ividiyo esebenza kahle kakhulu.
Igalari yezithombe
Ehhovisi lokuhlela, ngenjongo yokuthakasela, senze izivivinyo lapho siqophe khona ividiyo yomzuzu owodwa kuqala ngefomethi endala ye-H.264 bese kuba ngefomethi entsha ye-H.265. Ngenkathi ukufakwa kokuqala kungu-350,01 MB, okwesibili kuthathe u-204 MB ngefomethi esebenza kahle kakhulu. Ividiyo eku-HEVC ngakho-ke ayiwona neze uhhafu wosayizi, kodwa futhi incike kwezinye izici ezimbalwa, njengokuhlukahluka kombala kanye nenani lokukhanya esigcawini esithwebuliwe.
Okokugcina, kubalulekile ukuqaphela ukuthi i-HEVC nayo ine-drawback eyodwa enkulu. Yize amavidiyo ashuthwe kuyo emancane ngokuphawulekayo futhi esesezingeni eliphezulu, angadala inkinga mayelana nokuhambisana. Ifomethi ye-HEVC isesekuqaleni, ngakho-ke ayisekelwe izinhlelo ezihlukahlukene zokuhlela, futhi amadivaysi amadala, njengama-smartphone, amaphilisi futhi ikakhulukazi amathelevishini, anezinkinga ngayo.
