PakusarudzaTambo yeHDMI, tinowanzoona zita rekuti “1080P.” Zvinorevei chaizvo? Chinyorwa chino chinotsanangura zvakadzama.
1080Pndiyo mwero wepamusoro-soro wedhijitari wemhando yepamusoro-soro unotsanangurwa neSociety of Motion Picture and Television Engineers (SMPTE). Chiratidziro chayo chinoshanda che display resolution ndeche1920 × 1080, ine huwandu hwemapikiseli ese e2.0736 miriyoni. Hunhu hwepamusoro hwemifananidzo hunowanikwa ne1080P hunopa vatengi ruzivo rwechokwadi rwekunzwa nekuona mumitambo yemitambo. Nekuti inoenderana zvizere nemamwe mafomati eHD, inogona kushandiswa zvakasiyana-siyana uye inoshanda zvakanyanya.
Mukuita kwedhijitari, kurongeka kwemasaini edhijitari ndeimwe yenhanho dzakakosha. Kubva pamaonero anotarisa vatengi, parameter inonyanya kunzwisisika ndeyekujeka kwemufananidzoSMPTE inoisa zviratidzo zveHDTV zvedhijitari muzvikamu zvichienderana nenzira dzekuskena1080P, 1080I, uye 720P (iinomirirajira rekubatanidzauyepinomirirakufambira mberi).
1080P inoreva fomati yekuratidzwa inoita kuti1920 × 1080 resolution uchishandisa progressive scanning, zvichimiririra kubatanidzwa kwakakwana kwetekinoroji yemifananidzo yemafirimu edhijitari uye tekinoroji yemakomputa.
Kuti tinzwisise 1080P zvakajeka, tinofanira kutanga tatsanangura 1080i ne720P. 1080i ne720P zvese zviri zviviri zvinozivikanwa pasi rose nedhijitari. Nyika dzakatanga kushandisa sisitimu yeNTSC dzakatanga kushandisa1080i / 60Hzfomati, inoenderana nefrequency yeterevhizheni yeNTSC analog. Kusiyana neizvi, Europe, China, nedzimwe nzvimbo dzakatanga kushandisa system yePAL dzakashandisa1080i / 50Hz, inoenderana nePAL analog terevhizheni field frequency.
Nezve720P, yakava mwero wekusarudza nekuda kwekubatanidzwa kwakawanda kwevagadziri veIT muindasitiri yeterevhizheni uye kubva ipapo yave nekubata mumidziyo yekutamba yeHDTV inoshandisa madhisiki e optical senzira huru yekushandisa. Zvinofanira kucherechedzwa kuti1080P ndiyo chiyero chechokwadikuti zvinoitahaisipo pa60Hz cheteuye izvozvo1080P haina kufanana neFULL HD.
Saka chii chiriHD yakazara?
FULL HD inoreva materevhizheni e flat-panel anogonakuratidza zvizere 1920 × 1080 pixels, zvichireva kuti yavoresolution yemuviri (yemuno) ndeye 1920 × 1080Kuti uwane mhedzisiro yakanaka yekuona paunenge uchiona mapurogiramu eHDTV, terevhizheni yeFULL HD inodiwa. Zvakakosha kuziva kuti FULL HD haisi pfungwa imwechete ne "1080P" yakataurwa nevagadziri vazhinji kare.
ZvinonziRutsigiro rwe1080Pzvinoreva kuti terevhizheni inogonagamuchira uye gadzirisa zviratidzo zvevhidhiyo zve1920 × 1080, asi TV pachayo haifanirwe kunge iine resolution chaiyo ye1920 × 1080. Pane kudaro, inodzikisa mufananidzo we1920 × 1080 kusvika paresolution chaiyo isati yauratidza.
Semuenzaniso, aTerevhizheni yeLCD ye 32-inchinogona kunge iine mhinduro yepakutanga ye1366 × 768, asi bhuku rayo rekushandisa rinogona kutaura kuti inotsigira 1080P. Izvi zvinongoreva kuti inogona kugamuchira chiratidzo che1920 × 1080 uye yochishandura kuita 1366 × 768 kuti chionekwe. Muchiitiko ichi, “1080P” zvinorevamhinduro yepamusoro inotsigirwa kana kuti resolution yekuratidzwa, zvichiratidza kuti TV inogona kugamuchira chiratidzo che1920 × 1080, asi inogamuchirakweteiratidze pa resolution iyoyo yakazara.
