Okudingeka Ukwazi Ngo-720p no-1080p
Nakuba u- 4K uthola yonke i-buzz kulezi zinsuku njengoba isinqumo esiphezulu sitholakalayo kuma-TV namavidiyo weprojekthi, i-720p ne-1080p nayo inezinqumo eziphezulu ezicacile ezisetshenziswayo. Esinye isici se-1080p no-720p esivumelana ngaso sonke isikhathi ukuthi yizifomethi zokubonisa eziqhubekayo (yilapho i- "p" ivela khona). Noma kunjalo, yilapho ukufana phakathi kwe-720p no-1080p kuphetha.
Yeka ukuthi u-720p no-1080p umehluko kanjani
- I-720p ingamaphikseli angu- 1,280 aboniswe kwesikrini ngokuzungezile namaphikseli angu-720 phansi kweskrini ngokuqondile. Lokhu kuveza imigqa engama-720 enezingqimba esibukweni, okuyikho, ngokuboniswayo, kuboniswa kancane kancane, noma umugqa ngamunye uboniswa ngokulandela omunye.
- I-1080p imelela amaphikseli angu-1,920 aboniswe kwesikrini ngokuzungezile namaphikseli angu-1,080 phansi kwesikrini ngokuqondile. Lokhu kuphumela kuma-pixels angu-1,080 angemuva esibukweni, okube nawo, aboniswa kancane kancane, noma umugqa ngamunye wamaphikseli aboniswa ngokulandela omunye. Ngamanye amazwi, njengoba nje nge 720p, wonke imigqa yepikelli (imigqa) iboniswa kancane kancane.
Inani eliphelele lamaphikseli akha isithombe esingu-720p lingamamitha ayi-1 (okulingana no-megapixel ongu-1 kuyi-digital namanje ikhamera), kuyilapho kukhona amaphikseli ayizigidi ezingu-2 esithombeni se-1080p. Lokhu kusho ukuthi isithombe se-1080p singabonisa imininingwane eminingi kunesithombe se-720p.
Kodwa-ke, lokhu konke kuhumusha kanjani lokho okubonayo empeleni kwesikrini se-TV? Akufanele yini kube lula ukubona umehluko phakathi kwe-720p no-1080p TV? Akunjalo ngempela.
Ukuphakama kwe-720p no-1080p wephikseli, usayizi weskrini nokuhlala ubude kusuka kwesikrini kuyadingeka kucatshangelwe. Uma une-720p noma i-1080p ye-TV / ividiyo iphrofayli inombolo yamaphikseli aboniswe ngayinye ifana naphezu kokuthi ubukhulu beskrini - yiziphi izinguquko eziyinombolo yamaphikseli ngamasentimitha . Lokhu kusho ukuthi njengoba isikrini sithola sikhulu, ama-pixel akhula - futhi ibanga lakho lokuhlala lizophazamisa ukuthi ubona kanjani imininingwane eboniswe esikrinini.
720p, ukusakazwa kwe-TV, nekhebula / isatellite
Abasakazwa nge-TV kanye nabahlinzeki bama-cable / satellite bathumela uhlelo ngeziphakamiso eziningana. I-ABC ne-FOX (ehlanganisa iziteshi zabo zekhebula, njenge-ESPN, ABC Family, njll ...) sebenzisa i-720p, kuyilapho abanye abaningi abahlinzeki, njenge-PBS, i-NBC, i-CBS, i-CW, i-TNT, nezinsizakalo eziningi ze-premium, njenge-HBO , sebenzisa i-1080i. Ngaphezu kwalokho, kunezinye ikhebula kanye nama-satellite feeds athunyelwa ngo-1080p, futhi i- DirecTV inikeza uhlelo oluthile lwe-4K . Abahlinzeki bokusakazwa kwe-inthanethi bathumela izinqumo ezihlukahlukene, kufaka phakathi i-720p, 1080p, ne-4K.
Ukuze ikhebula ne-satellite, i-720p TV izokhipha amasignali wokufaka ama- 1080i no-1080p ngokuvumelana nesinqumo sayo samaphikseli asoqobo (ama-720p TV awahambisani nempawu ezine-4K). Uma ufinyelela okuqukethwe ngokusebenzisa umsakazo wezindaba ungasetha umkhiqizo ukufanisa isinqumo sakho se-TV. Uma unayo i- smart TV , izokwandisa isignali yokusakaza yokusakaza ukuze ifane nesinqumo sokubonisa.
I-Blu-ray ne-720p
Ngokuphambene nalokho abaningi bacabanga ukuthi ungasebenzisa isidlali se-Blu-ray Disc nge-720p TV . Bonke abadlali be-Blu-ray disc bangasethwa ukuze bakhiphe 480p / 720p / 1080i / noma 1080p nge- HDMI yokukhishwa kokukhipha.
Futhi, uma uxhumeke ku-TV noma iprojector yevidiyo nge-HDMI, abadlali abaningi be-Blu-ray Disc bazitholela ngokuzenzakalelayo isinqumo somdabu se-TV / iphrosesa abaxhunyiwe kuyo futhi bazobeka isinqumo sokukhishwa ngendlela efanele. Abadlali be-Blu-ray Disc banikeza ikhono lokusetha isinqumo sokukhishwa ngesandla.
Okubalulekile - Ingabe Kufanele Uthenge i-720p TV?
Ukuze uphendule lo mbuzo, kuzomele kuqaphele ukuthi iningi lamabhayisikobho manje liyi-4K, kodwa kusekhona inombolo (nakuba yehla) ama-TV angu-1080p atholakalayo. Noma kunjalo, amanani aphansi we-4K Ultra HD TV awagcini nje ukubeka ingcindezi ekutholakaleni kwama-TV angu-1080p kodwa anciphisa kakhulu ukutholakala kwama-TV angu-720p, ukuwaphonsa phansi kusigaba sesayizi esincane sesikrini - akuvamile ukubona i-720p TV enikezwe ubukhulu beskrini bukhulu kunama-intshi angu-32.
Kumele futhi kuqaphele ukuthi iningi lamabhayisikobho abhalwe manje njengama-TV angu-720p empeleni anezixazululo zesibalo se-pixel esivela ku-1366x768, okuyisisekelo esingu-768p. Noma kunjalo, zivame ukukhangiswa njengezingu-720p ze-TV. Ungavumeli lokhu kukulahle, lawa maqoqo azokwamukela wonke ama-720p, 1080i , kanye nama-1080p wokusombulula izimpawu. I-TV izocubungula futhi isilinganise noma yikuphi ukuxazulula okungenayo kwisinqumo sayo sokubonisa isibonisi se-pixel esingu-1366x768.
Uyabona kanjani umahluko phakathi kuka 720p, 1080p, noma esinye isinqumo, kuwona okwenzekayo okubukayo nge-TV yakho. Ungathola ukuthi i-720p TV ethize ingabheka kangcono kune-TV ethile ye-1080p njengoba isinqumo singesinye sezici. Impendulo yokunyakaza, ukucubungula umbala, ukuqhathanisa, ukukhanya, nokuphakanyiswa kwevidiyo noma ukuhlaselwa phansi kunomthelela ekukhwalweni kwesithombe.
Yiqiniso, ikhwalithi yesignali yomthombo nayo idlala ingxenye enkulu. Iprojector yevidiyo ye-TV ingakwazi ukukhokhela kuphela amakhomitha omthombo wekhwalithi ompofu, ikakhulukazi nge-VHS noma ikhebula le-analog, futhi, ngenxa yemithombo yokusakaza ye-intanethi, ikhwalithi ayincike kuphela kumthombo kodwa isivinini sakho sokusakaza kwe-intanethi .
Vumela amehlo akho abe ngumqondisi wakho.
