Kumvetsetsa Video Frame Rate ndi Screen Refresh Mitengo
Kugula kwa TV masiku ano sikungakhale kosavuta monga kale. Pogwiritsa ntchito mawu oterewa monga HDTV , Progressive Scan , 1080p , 4K Ultra HD , Frame Rate, ndi Screen Refresh Rate, wogula akukuta ndi madzi omwe ali ovuta kuwongolera. Mwazinthu izi, ziwiri zovuta kwambiri kuzimvetsa ndi Zomwe Zakhazikitsa ndi Vuto Lotsitsimula.
Mafelemu Otani Ali
Mu kanema (onse analog ndi tanthauzo lapamwamba), monga momwe amaonera filimu, mafano amawonetsedwa ngati Mafelemu. Komabe, pali kusiyana pakati pa mafelemu omwe amawonetsedwa pa TV. Malingana ndi mavidiyo a chikhalidwe, m'mayiko omwe akuchokera ku NTSC muli mafelemu 30 omwe amawonetsedwa mphindi iliyonse (1 chimango chokwanira chilichonse 1/30 chachiwiri), pamene ali mu maiko a PAL, pali mafelemu 25 omwe amawonetsedwa mphindi iliyonse (1 chimango chokwanira chinasonyezedwa zonse 25 zachiwiri). Mafelemu awa amawonetsedwa pogwiritsira ntchito njira ya Interlaced Scan kapena njira ya Progressive Scan .
Komabe, popeza filimu ikuwombera pa mafelemu 24 pamphindi (1 chimango chokwanira chikuwonetsedwa ma 24 onse a sekondi), kuti muwonetse filimu pawindo lamakanema, mafelemu 24 oyambirira ayenera kutembenuzidwa kukhala mafelemu 30 ndi ndondomeko yotchedwa 3 : Malo awiri.
Ndi Vuto la Zotsitsimutsa Lililonse
Malinga ndi matekinoloje a lero omwe amawonetsedwa pa televizioni, LCD, Plasma, ndi DLP monga maofesi, monga Blu-ray Disc (komanso ma DVD) tsopano, chinthu china chatseketsa momwe mafelemu a Mavidiyo akuwonetsedwa pawindo: Mndandanda Wotsitsimula. Mphamvu yotsitsimula imasonyeza nthawi zingati TV, mavidiyo, kapena chithunzi chojambula chimamangidwanso kwathunthu. Lingaliro ndiloti nthawi zambiri pulogalamuyi imakhala "yotsitsimutsidwa" mphindi iliyonse, kuyendetsa chithunzichi ndikutanthauzira kuthamanga ndi kuwombera.
Mwachiyankhulo china, fano likuwoneka bwino bwino kuti chinsalucho chikhoza kudzikongoletsa. Kutsitsimula ma TV ndi mavidiyo ena omwe amawonetsedwa amawerengedwa mu "Hz" (Hertz). Mwachitsanzo, televizioni yomwe ili ndi 60hz mlingo wotsitsimula imasonyeza kukonzanso kwathunthu kwa chithunzi cha pulogalamu yamphindi 60 kamphindi iliyonse. Zotsatira zake, izi zimatanthauzanso kuti vidiyo iliyonse (mu chimango cha 30 pa chizindikiro cha sekondi) imabwerezedwa kawiri pa 60 iliyonse yachiwiri. Poyang'ana masamu, munthu amatha kuzindikira momwe maonekedwe ena amalinganirana ndi ziwerengero zina zotsitsimula.
Zotsatira za Vesi vs Refresh Rate
Chomwe chimapangitsa zinthu kusokoneza ndi lingaliro la kuchuluka kwa mafelemu osiyana ndi owonetserako omwe amasonyezedwa mphindi iliyonse, poyerekeza ndi kangati nthawi yomwe firimu imabwerezedwa nthawi zonse 1/24, 1/25, kapena 1 / 30th yachiwiri kuti lifanane ndi mphindi yotsitsimula ya Kuwonetserako TV.
Ma TV ali ndi mphamvu zawo zowonetsera zowonekera. Mawindo othandizira mafilimu a pa TV amayenera kutchulidwa mu bukhu lamagwiritsidwe ntchito kapena pa tsamba lokonzekera lajambula.
Mtengo wotsitsimula kwambiri wa makanema a lero ndi 60 Hz kwa machitidwe a NTSC ndi 50 Hz za ma PAL. Komabe, poyambitsa magulu ena a Blu-ray Disc ndi HD-DVD omwe angathe kutulutsa mawonekedwe 24 pa sewero lachiwiri la kanema, mmalo mwa chithunzi cha 30 pa sewero lachiwiri la kanema, miyeso yatsopano yotsitsimula ikugwiritsidwa ntchito ndi ena opanga ma TV kuti agwirizane ndi zizindikiro izi mu chiwerengero choyenera cha masamu.
Ngati muli ndi TV yomwe ili ndi 120Hz yomwe imakhala yofanana ndi 1080p / 24 (pixels 1920 pawindo ndi 1080 pixels pansi pa chinsalu, ndi mawonekedwe 24 pa mphindi mlingo). TV imathera kuwonetsera mafelemu 24 pamphindi iliyonse koma imabwereza chimango chilichonse molingana ndi mlingo wokonzanso wa TV. Pankhani ya 120 Hz, chimango chilichonse chidzawonetsedwa kasanu ndi kawiri mkati mwa mphindi iliyonse yachiwiri.
Mwa kuyankhula kwina, ngakhale ndi miyeso yowonjezera yowonjezera, pali mafelemu 24 okha omwe amawonetsedwa mphindi iliyonse, koma angafunikire kuwonetsedwa kangapo, malingana ndi msinkhu wotsitsimula.
- Kuti muwonetse mafelemu 24 pamphindi pa TV ndi mazenera a refreshing 120 Hz, chimango chilichonse chikubwerezedwa kasanu ndi kamodzi pa sekondi iliyonse yachiwiri.
- Kuti muwonetse mafelemu 24 pamphindi pa TV ndi ndondomeko yotsitsimutsa 72 Hz, chimango chilichonse chimabwerezedwa katatu pamphindi 24 iliyonse.
- Kuti muwonetse mafelemu 30 pamphindi pa TV ndi ma pulogalamu yotsitsimutsa 60 Hz, chimango chilichonse chikubwerezedwa 2 nthawi iliyonse ya makumi atatu.
- Kuti muwonetse mafelemu 25 pamphindi pa TV ndi ndondomeko yotsitsimula 50 Hz ( Mayiko a PAL ), chimango chilichonse chikubwerezedwa 2 nthawi iliyonse ya 25 yachiwiri.
- Kuti muwonetse mafelemu 25 pamphindi pa TV ndi phindu la kutsitsimula 100 Hz (Mayiko a PAL), chimango chilichonse chikubwerezedwa 4 nthawi iliyonse ya 25 yachiwiri.
ZOYENERA: Tsatanetsatane yomwe ili pamwambapa ili ndi chiwerengero choyera. Ngati TV ikuyeneranso kupanga fomu 24 pamphindi pa 30 mafelemu pamphindi kapena pamtundu umodzi pamasamba kutembenuka, ndiye kuti muyeneranso kuthana ndi 3: 2 kapena 2: 3 Pulldown, yomwe imapanganso masamu. Pulogalamu 3: 2 ikhoza kuchitidwa ndi DVD kapena Blu-ray Disc player, kapena chipangizo china chisanafike chizindikirocho kufika pa TV.

Ngati TV ndi 1080p / 60 kapena 1080p / 30 - yogwirizanitsa zokha, sizivomereza 1080p / 24 input. Pakalipano, ma CD Blu-ray ndi ma DVD-DVD okha ndizo zimayambira 1080p / 24 zakuthupi. Komabe, mafilimu ambiri a Blu-ray ndi HD-DVD amasintha chizindikiro cha 1080p / 60 kapena 1080i / 30 kuti chidziwitso chitha kukonzedwa ndi TV bwino kuti zisamangidwe ngati sizigwirizana ndi 1080p / 24.
ZOYENERA: Ngakhale ma TV 1080p / 60 okhawo sangathe kuwonetsera ma TV 1080p / 24 - 1080p / 24 akhoza kusonyeza 1080p / 60 kudzera pa kanema.
Chinthu chonsecho chimagwera pa lingaliro la mafelemu osiyana ndi mafelemu obwerezabwereza. Pankhani ya malipiro a chithunzi ndi mawerengedwe a zotsitsimutsa, mafelemu obwerezedwa mobwerezabwereza sali ngati mafelemu osiyana monga momwe zidziwitso mu mafelemu obwereza ndi ofanana. Ndi pamene mutasunthira ku chimango chokhala ndi chidziwitso chosiyana chomwe mukuchiwerengera ngati chimango chatsopano.
Kuwunika Kutsatsa
Komabe, kuwonjezera pa mlingo wokonzanso zowonetsera, njira ina imene opanga TV ena amagwiritsa ntchito yomwe ingathandize kuyendetsa kayendetsedwe kake ndi kuchepetsa kusuntha koyendetsedwe kumatchedwanso Kabukhu Kakang'ono. Mwa kuyankhula kwina, tiyeni tizinena kuti TV ili ndi madigiri oposa 120 Hz. N'zotheka kuti iyenso imaphatikizapo kuwalako komwe kumawunikira ndi kutuluka mofulumira pa 120 Hz yowonjezera iliyonse (pakati pa mapepala otsitsimutsa pafupipafupi mobwerezabwereza). Njirayi imapangitsa kuti pakhale mawindo atsitsi a 240 Hz pogwiritsa ntchito chinyengo.
Pa ma TV omwe amagwiritsa ntchito teknolojiyi, ikhoza kuwonetseredwa kapena kulephereka pokhapokha kuwonetsera kayendedwe kowonetsera masewera, ngati zotsatira za njira yowunikira kumbuyo siikonda.
