Xa ukhethaIntambo yeHDMI, sihlala sibona ilebhile ethi “1080P.” Ithetha ukuthini ngokwenene? Eli nqaku lichaza ngokweenkcukacha.
1080Pyimigangatho yefomathi yedijithali yedijithali ekumgangatho ophezulu echazwe yiSociety of Motion Picture and Television Engineers (SMPTE). Isisombululo sayo esisebenzayo sesiboniso1920 × 1080, kunye nenani lilonke lee-pixel2.0736 yezigidi. Umgangatho ophezulu womfanekiso oveliswa yi-1080P unika abathengi amava okwenyani omsindo nomboniso obonakalayo kwinqanaba lemidlalo yasekhaya. Ngenxa yokuba ihambelana ngokupheleleyo nezinye iifomathi ze-HD, iguquguqukayo kakhulu kwaye iyasebenza ngokubanzi.
Kwinkqubo yokwenza idijithali, ukubekwa emgangathweni kwemiqondiso yedijithali yenye yezona nyathelo zibalulekileyo. Ukusuka kwimbono egxile kubathengi, eyona parameter iqondakalayo yileukucaca komfanekisoI-SMPTE ihlela imiqondiso ye-HDTV yedijithali ngokusekelwe kwiindlela zokuskena zibe1080P, 1080I, kunye ne-720P (iimele ii-interlacekunyepimele iinkqubela phambili).
I-1080P ibhekisa kwifomathi yokubonisa efikelelaIsisombululo se-1920 × 1080 kusetyenziswa ukuskena okuqhubekayo, emele ukuhlanganiswa okugqibeleleyo kobuchwepheshe bokufota ngemifanekiso yesinema yedijithali kunye nobuchwepheshe bekhompyutha.
Ukuze siqonde ngokucacileyo i-1080P, kufuneka siqale sichaze i-1080i kunye ne-720P. Zombini i-1080i kunye ne-720P zimigangatho yedijithali ephezulu eyaziwayo kwihlabathi liphela. Amazwe awayesebenzisa inkqubo ye-NTSC ekuqaleni amkele i-1080i / 60Hzifomathi, ehambelana nesantya se-NTSC analog TV. Ngokwahlukileyo koko, iYurophu, iTshayina, kunye neminye imimandla eyayisebenzisa inkqubo ye-PAL ekuqaleni yamkela1080i / 50Hz, ehambelana ne-PAL analog field frequency.
Ngoko720P, yaba ngumgangatho onganyanzelekanga ngenxa yokubandakanyeka okunzulu kwabavelisi be-IT kushishino lwethelevishini kwaye ukususela ngoko iye yafumana ukuthandwa kwezixhobo zokudlala ze-HDTV ezisebenzisa iidiski ze-optical njengesixhobo esiphambili. Kufuneka kuqatshelwe ukubaI-1080P yimigangatho eqhelekileyo, ukuba iyenzaayikho kwi-60Hz kuphela, kwaye okoI-1080P ayifani ne-FULL HD.
Ngoko ke yintoniI-HD EPHELELEYO?
I-FULL HD ibhekisa kwiithelevishini ezineephaneli ezisicaba ezinokukwaziibonisa ngokupheleleyo iiphikseli eziyi-1920 × 1080, oko kuthetha ukubaisisombululo somzimba (semveli) yi-1920 × 1080Ukuze ufumane iziphumo ezilungileyo zokubukela xa ubukele iinkqubo ze-HDTV, kufuneka ithelevishini ye-FULL HD. Kubalulekile ukuqaphela ukuba i-FULL HD ayifani nengcamango ethi “1080P” ebangwe ngabavelisi abaninzi ngaphambili.
Okubizwa ngokubaInkxaso ye-1080Pkuthetha ukuba umabonwakude unakoyamkela kwaye uqhube imiqondiso yevidiyo eyi-1920 × 1080, kodwa iTV ngokwayo ayinaso isisombululo esibonakalayo se-1920 × 1080. Endaweni yoko, inciphisa umfanekiso we-1920 × 1080 ukuya kwisisombululo sayo sokuqala ngaphambi kokuba iwubonise.
Umzekelo, iI-TV ye-LCD engama-intshi angama-32inokuba nesisombululo sendalo se1366 × 768, kodwa incwadi yayo yemiyalelo ingatsho ukuba ixhasa i-1080P. Oku kuthetha ukuba ingayamkela isignali ye-1920 × 1080 kwaye iyiguqulele kwi-1366 × 768 ukuze iboniswe. Kule meko, “1080P” ibhekisa kwiisisombululo esiphezulu esixhaswayo sokufaka okanye sokubonisa, nto leyo ebonisa ukuba iTV ingafumana isignali ye-1920 × 1080, kodwa iyayifumanahayiyibonise kweso sisombululo sipheleleyo.
