Mvetsetsani 1080P mu HDMI mwachidule

MukasankhaChingwe cha HDMI, nthawi zambiri timaona chizindikiro chakuti “1080P.” Kodi kwenikweni chimatanthauza chiyani? Nkhaniyi ikufotokoza mwatsatanetsatane.

1080Pndi muyezo wapamwamba kwambiri wa digito wa kanema wa pa TV wofotokozedwa ndi Society of Motion Picture and Television Engineers (SMPTE). Chiwonetsero chake chogwira ntchito bwino ndi1920 × 1080, ndi chiwerengero chonse cha ma pixel2.0736 miliyoni. Ubwino wa zithunzi zomwe zimaperekedwa ndi 1080P umapatsa ogula mwayi wowona bwino kwambiri pa malo ochitira zisudzo kunyumba. Chifukwa chakuti imagwirizana ndi mitundu ina ya HD, ndi yosinthasintha kwambiri komanso yogwiritsidwa ntchito kwambiri.

Mu ndondomeko ya digito, kukhazikika kwa zizindikiro za digito ndi chimodzi mwazofunikira kwambiri. Kuchokera pamalingaliro oganizira ogula, gawo lodziwika bwino kwambiri ndikumveka bwino kwa chithunziSMPTE imagawa zizindikiro za HDTV za digito kutengera njira zojambulira1080P, 1080I, ndi 720P (iimayimiracholumikizirandipimayimirakupita patsogolo).
1080P imatanthauza mawonekedwe owonetsera omwe amakwaniritsa1920 × 1080 resolution pogwiritsa ntchito progressive scanning, zomwe zikuyimira kuphatikiza kwabwino kwa ukadaulo wa kujambula zithunzi za digito ndi ukadaulo wa makompyuta.

Kuti timvetse bwino 1080P, choyamba tiyenera kufotokoza 1080i ndi 720P. 1080i ndi 720P zonse ndi miyezo yodziwika padziko lonse lapansi ya digito yapamwamba kwambiri. Mayiko omwe poyamba ankagwiritsa ntchito njira ya NTSC adagwiritsa ntchito njira iyi.1080i / 60Hzmtundu, womwe umagwirizana ndi ma field frequency a NTSC analog TV. Mosiyana ndi zimenezi, Europe, China, ndi madera ena omwe poyamba ankagwiritsa ntchito PAL system adagwiritsa ntchito1080i / 50Hz, yofanana ndi ma frequency a wailesi yakanema ya analog ya PAL.
Ponena za720P, inakhala muyezo wosankha chifukwa cha kutenga nawo mbali kwakukulu kwa opanga IT mumakampani opanga ma TV ndipo kuyambira pamenepo yakhala ikukopa zida zosewerera za HDTV zomwe zimagwiritsa ntchito ma disc optical ngati njira yayikulu yolumikizira. Tiyenera kudziwa kuti1080P ndi muyezo weniweni, kuti zimaterosizikupezeka pa 60Hz yokhandipo zimenezo1080P si yofanana ndi FULL HD.

Ndiye nchiyaniHD Yonse?
FULL HD ikutanthauza ma TV a flat-panel omwe angathekuwonetsa kwathunthu ma pixel a 1920 × 1080, kutanthauza zawoChisamaliro chakuthupi (chachilengedwe) ndi 1920 × 1080Kuti muwonere bwino kwambiri mukamaonera mapulogalamu a HDTV, pamafunika wailesi yakanema ya FULL HD. Ndikofunikira kudziwa kuti FULL HD si lingaliro lofanana ndi "1080P" lomwe opanga ambiri adanena kale.

WotchedwaThandizo la 1080Pzikutanthauza kuti TV ikhozakulandira ndikugwiritsa ntchito zizindikiro za kanema za 1920 × 1080, koma TV yokha siili ndi resolution yeniyeni ya 1920 × 1080. M'malo mwake, imatsitsa chithunzi cha 1920 × 1080 kufika pa resolution yake yeniyeni isanayambe kuiwonetsa.
Mwachitsanzo,TV ya LCD ya mainchesi 32akhoza kukhala ndi lingaliro lachibadwa la1366 × 768, komabe buku lake la malangizo linganene kuti limagwira ntchito ndi 1080P. Izi zikutanthauza kuti likhoza kulandira chizindikiro cha 1920 × 1080 ndikuchisintha kukhala 1366 × 768 kuti chiwonetsedwe. Pankhaniyi, “1080P” ikutanthauzakulowetsa kapena kuwonetsa kokwanira komwe kumathandizidwa, zomwe zikusonyeza kuti TV ikhoza kulandira chizindikiro cha 1920 × 1080, koma imalandiraosationetsani pa resolution yonseyo.
