Oko Kufuneka Ukwazi Ngo-720p no-1080p
Nangona i- 4K ifumana yonke i-buzz kule mihla njengesixazululo esiphezulu seTV kunye neeprojekti zevidiyo, i-720p kunye ne-1080p nazo ziyizigqibo eziphakamileyo ezisetyenziswayo. Esinye isici esiyi-1080p kunye ne-720p esivamelanayo kukuba ziyiifomati zokubonisa eziqhubekayo (apho "p" ivela khona). Nangona kunjalo, oku kukuthi ukufana phakathi kwe-720p no-1080p kuphelile.
I 720p no-1080p ihluke njani
- I-720p yi- pixels eyi-1,280 iboniswe kwi-skrini ngasemva kunye nee-pixels ezingu-720 phantsi kwesikrini. Oku kuvelisa imizila engama-720 ejikelezayo kwiskrini, leyo leyo, ngokubhekiselele, iboniswa ngokuthe gqolo, okanye umgca ngamnye uboniswe emva kwesinye.
- I-1080p ibonisa iipekseli eziyi-1,920 eziboniswe kwinqanaba elingaphandle kunye neeplayseli ezili-1,080 phantsi kwesikrini ngokuzenzekelayo. Oku kuphumela kuma-pixels angama-1,080 angama-horizontal kwisikrini, ezo zibonakaliswa ngokukhawuleza, okanye nganye imida yeepekseli iboniswe emva kwesinye. Ngamanye amazwi, njengokuba nge 720p, yonke imigqa yepikel (imigca) iboniswa ngokuthe gqolo.
Inani elipheleleyo leepekseli ezenza umfanekiso we-720p lilingana nezigidi ezili-1 (ezilingana ne-megapixel enye kwi-digital nesekhamera), ngelixa kukho ii-pixels ezigidi ezi-2 kumfanekiso we-1080p. Oku kuthetha ukuba umfanekiso we-1080p ungabonakalisa inkcazelo eninzi kunomfanekiso we-720p.
Nangona kunjalo, le nto iguqulela njani into oyibona kwithempyuthele yeTV? Ngaba akufanele kube lula ukubona umehluko phakathi kwe-720p ne-1080p TV? Akunjalo.
I-720p kunye ne-1080p ye-pixel ubuninzi, ubungakanani bekrini kunye nokuhlala umgama ukusuka kwisikrini kufuneka kuthathelwe ingqalelo. Ukuba unayo i-720p okanye i-1080p ye-TV / iprojekthi yeprojekthi inombolo yeepekseli eboniswe nganye iyafana nokuba kungakanani ubungakanani besikrini - yiziphi iinguqu ziyi- pixels nge intshi . Oku kuthetha ukuba njengoko isikrini siba sikhulu, iipikseli ziba zikhulu - kwaye umgama wakho wokuhlala uya kuthintela njani ukuba uyazibona iinkcukacha eziboniswe kwisikrini.
720p, iiTV, kunye neChethern / Satellite
Abasasazwa ngeTV kunye nabanikezeli beeklayiti / ze-satellite bathumela iinkqubo kwizigqibo ezininzi. I-ABC ne-FOX (ebandakanya iziteshi zabo zekhebula, ezifana ne-ESPN, ABC Family, njl ...) sebenzisa i-720p, ngelixa abanye abaninzi ababoneleli, njenge-PBS, i-NBC, i-CBS, i-CW, i-TNT kunye neenkonzo ezininzi ze-premium, ezifana ne-HBO , sebenzisa i-1080i. Ukongezelela, kukho ikhefu kunye neefayili ezithunyelwa kwi-1080p, kwaye i- DirecTV inika iprogram ye-4K . Ababoneleli be-intanethi bayithumela izigqibo ezininzi, kubandakanya 720p, 1080p, ne-4K.
I-cable kunye ne-satellite, i-TV ye-720p iya kumisa amanqaku angama- 1080i kunye ne-1080p ngokuvumelana nesisombululo se-pixel yaso yangaphandle (ii-TV ze-720p azihambelani ne-4K). Ukuba ufaka umxholo nge- media streamer ungasetha umphumo ukufanisa isisombululo sakho seTV. Ukuba unayo i- TV ye-TV , iya kukulinganisa uphawu lokusasaza oluzayo ukuze luhambisane nesisombululo sokubonisa.
Blu-ray kunye no 720p
Ngokuchasene noko abaninzi bacinga ukuba ungasebenzisa umdlali we-Blu-ray Disc nge-720p TV . Bonke abadlali be-Blu-ray disc bangasetyenziselwa ukuvelisa i-480p / 720p / 1080i / okanye i-1080p ngokusebenzisa uxhumano lwentengo ye- HDMI .
Kwakhona, xa uxhunyiwe kwiTV okanye iprojekti yevidiyo nge-HDMI, abaninzi abadlali be-Blu-ray Disc bafumanisa ngokuzenzekelayo isisombululo somthonyama seTV / projekthi abaxhunyiwe kuyo kwaye baya kubeka isisombululo sesiphumo ngokufanelekileyo. Abadlali be-Blu-ray Disc banikezela ukuba bakwazi ukubeka isisombululo sesiphumo ngesandla.
Umxholo ophantsi - Ngaba ufanele uthenge iTV 720p?
Ukuze uphendule lo mbuzo, ku funeka kuqatshelwe ukuba ininzi yeTV yakwii-4K, kodwa kusekho inani (nangona lihla) i-TV ye-1080p iyatholakala. Nangona kunjalo, amanani aphantsi kwi-4K Ultra HD TV ayifuni nje ukubeka uxinzelelo kwi-TV ye-1080p kodwa iyanciphisa kakhulu ukufumaneka kwee-TV ze-720p, ukuzitshintsha phantsi kwinqanaba elincinci lesayizi leskrini - akunqabile ukubona i-720p TV enikezelwa ubukhulu besikrini obukhulu kunama-intshi angama-32.
Kufuneka kwakhona kuqaphele ukuba ezininzi iiTV ezibhalwa njengama-TV ye-720p ngokwenene zinezigqibo zokusombulula i-pixel yasekuhlaleni ye-1366x768, eyiyo eyi-768p. Nangona kunjalo, zivame ukupapashwa njengee-TV ze-720p. Ungavumeli le nto ikuphonsele, ezi setethi ziya kwamkela i-720p, i- 1080i , kunye ne-1080p isisombululo. I-TV iya kuqhuba kwaye ilandise nayiphi isisombululo esingenayo kwisigqibo sayo sokubonisa isibonakaliso se-pixel esingu-1366x768.
Uyabona njani umahluko phakathi kwe-720p, 1080p, okanye nayiphi enye isisombululo, kwimeko ebonakalayo yokujonga i-TV yakho. Unokufumana ukuba i-720p TV ethile ingabonakala ibhetele kuneTV ye-1080p njengoko isisombululo sinye kuphela. Impendulo yeempendulo, ukulungiswa kombala, ukuphambana, ukukhanya, kunye nevidiyo ukuphakanyiswa okanye ukunciphisa igalelo kunokuba negalelo kumgangatho wesithombe.
Ewe, umgangatho wesignali yomthombo udlala inxalenye enkulu. Umtshini wevidiyo womabonwakude unokuhlawula kuphela amanqaku omthombo weempawu ezimbi, ngokukodwa ngeVHS okanye ikhebula le-analog, kwaye, kwimithombo ye-intanethi ye-intanethi, umgangatho awuxhomeki kuphela kwimvelaphi kodwa isivinini sakho sokusasaza kwe-intanethi .
