I-DVR 4K, ebizwa nangokuthi i-Digital Video Recorder 4K / Digital 4 Ikhamera Recorder / 4K DVR System / 4K DVR CCTV / 4K DVR CCTV / 4K DVR Amazon, kusho ukuthi le DVR inesinqumo se-4K.
Ngakho-ke kusho ukuthini u-4k?
Ensimini yezobuchwepheshe yedijithali, abantu bavame ukusebenzisa imisebenzi kanambambili kanye namaphikseli ukuchaza usayizi wesithombe sedijithali. Ngenxa yenani elikhulu lamaphikseli akha isithombe sedijithali, usayizi wesithombe sedijithali uvame ukumelwa yi-K. Amandla we-10 ka-2 ngu-1024, ngakho: 1 = 1024, 24 = 2048, 4k = 2 ^ 12 = 4096. Mangaki amaphikseli angama-1024 akhona esiqondisweni esivundlile asho ukuthi ividiyo engakanani. Ngokukhuluma ngokuqondile, ngokwesibonelo, isixazululo 2048 × 1080, 2048 simelela inani lamaphikseli eqonde ngqo futhi ngo- 1080 limelela inani lamaphikseli aqonde mpo; Ngokufanayo, lapho isinqumo singama-4096 × 2160, 4096 simelela inani lamaphikseli erekhondweni evundlile, futhi angama-2160 amele inani lamaphikseli aqonde mpo. Ekukhiqizweni kwangempela kwe-alphanumeric nohlobo lwedijithali, inani lamaphikseli ekuqondisweni okuvundlile noma okuqondile kwesithombe kudinga ukulungiswa ngokuya ngezilinganiso ezihlukile zoMfanekiso. Ngakho-ke, ukulungiswa kwamaphikseli angama - 8847360 eduze kwesithombe se-4K nakho kungabizwa ngokuthi yi-4K Futhi ukukhuluma ngokuqinile, ukulungiswa kwe-Calve 4k kungukuthi nje amaphiki amaphikseli wesinqumo se-248 × 1080, nezikhathi eziyi-16 inani lamaphikseli we- 12 × 540.
Ukulungiswa kwesinqumo se-4k kungokwesinqumo se-Ultra HD, okusho ukuthi izilaleli zizokwazi ukubona yonke imininingwane futhi zisondele ezithombeni / amavidiyo kulesinqumo se-4K. Uma ukulungiswa kwe-4k kufakwa kwi-cinema, i- audienceencecan ibona inyamazane yonke futhi isondelene nefilimu noma ngabe iyiphi ikhosi ye-cinema ayikho.
Isixazululo se-4k sibhekisela kulokho inani le-pixel umugqa ngamunye endaweni evundlile lifinyelela noma lisondela ku-4096, kungakhathalekile ukuthi isilinganiso sini Ukulungiswa kwesinqumo se-4k nakho kunezinqumo ezahlukahlukene ezisuswayo , njenge- aperture ephelele 4K (4096 * 3112), i-Academy 4K (3656 * 2664), kanye ne-UHDTV 4K * 2160), njll. Futhi enkombeni yezokuphepha nezokuvikelwa , lapho sisho isisombululo se-4K, kubhekiswa kuma-3860 * 2160W Pixels.
Isinqumo se-4K sifanelana nesixazululo sesixazululo sesizukulwane esisha se-hollywood blockbusters. Kwehlukile kukho konke okubizwa ngokuthi i-High-Deserthery TV (1920 × 1080 Resolution) esibuke ekhaya kanye nesikrini esikhulu sesinqumo se-2k (2048 × 1080 Resolution) ye-cinema yendabuko yedijithali, isisombululo se-4K sisho ividiyo ye-Ultra- High kwesinqumo se-4096 × 21000. I-TV yendabuko ephezulu ibonisa ividiyo yamaphikseli ayizigidi eziyi-2.07, i-cinema yendabuko yendabuko ikhombisa ividiyo yamaphikseli ayizigidi ezingama-2.21, kuyilapho i-4096 × the the the the themeal sencazelo ephezulu yamaphikseli angama-8.85.
Ekuphetheni, kufanele sazi kahle nge-4K kanye nesinqumo, bese ukhetha isixazululo esifaneleke kakhulu lapho sithenga idivaysi kagesi, i-DVR, idivaysi yokuhlola ukuphepha noma okuthile.
