Kunzwisisa Video Frame Rates uye Screen Refresh Rates
Kutenga terevhizheni mazuva ano hazvirevi nyore sezvazvaimbova. Nemashoko ari kutumirwa kumativi akadai seHDTV , Progressive Scan , 1080p , 4K Ultra HD , Frame Rate, uye Screen Refresh Rate, mutengi ari kuvharwa nemagetsi anooma kutarisa. Kubva pamashoko aya, zviviri zvezvinonyanya kuoma kuita pfungwa ndeye Frame Rate uye Refresh Rate.
Ndezvipi Mafaira
Mumavhidhiyo (zvose analog uye tsanangudzo yakakwirira), sezvinongoita mufirimu, mifananidzo inoratidzwa seFrames. Zvisinei, kune kusiyana kune nzira iyo mapurisa anoratidzwa pane terevhizheni. Maererano nemitambo yemavhidhiyo, muNTSC-based nyika kune mafaira makumi matatu akasiyana-siyana anonyatsoratidzwa mashure ose (1 fomu yakakwana yega yega 1/30 yechipiri), asi muPAL-based countries, pane mapuranga makumi maviri nemaviri akaratidzwa mashure ose (1 chimiro chakakwana chakaratidzwa zvose zvechipiri chechipiri). Mapuranga aya anogona kuratidzwa achishandisa nzira ye Interlaced Scan kana kuti Progressive Scan nzira.
Zvisinei, sezvo firimu inodururwa pamapuranga makumi maviri nemasere nechipiri (1 firimu yakakwana inoratidzirwa yese ye 24 yechipiri), kuitira kuti iratidze firimu pane inoratidzira firimu rekuona terevhizheni, mapepa 24 epakutanga anofanira kushandurwa kuva makumi matatu makumi matatu nemaitiro anozivikanwa se 3 : 2 pulldown.
Chii Chinodzosera Mudikanwi Chaizvo
Nemazuva ano terevhizheni ekuratidzira maitiro, LCD, Plasma, uye DLP, uyewo ma-dis-based formats, zvakadai seBlu-ray Disc (pamwe chete neyezvino inonzi HD-DVD), chimwe chinhu chakapinda muchitamba chinokanganisa mafaira Vhidhiyo yehutano inoratidzwa pahwindo: Refresh Rate. Kudzorera purogiramu inomiririra kangani nguva iyo TV chaiyo, mavhidhiyo ekuratidzira, kana mufananidzo wechinyorwa wakarongedzwa unogadziridzwa zvakare yese yechipiri. Mhedziso ndeyekuti kana nguva yakawanda yechinyorwa "ichizorodzwa" chepiri yechipiri, iyo inotonhora chifananidzo chiri mumashoko ekufambisa kutsvaira uye kuderedza kupera.
Mune mamwe mazwi, chifananidzo chinotaridzika zviri nani nekukurumidza chipikicha chinogona kuzvisimbisa. Kuvandudza mitambo yemavhevhizheni nemamwe mavhidhiyo evhidhiyo anoenzaniswa mu "Hz" (Hertz). Semuenzaniso, terevhizheni ine 60hz yerefesheni yekuvandudza inomiririra kugadzirisa zvakare kwechiso chemufananidzo kanomwe makumi matanhatu nechipiri. Somugumisiro, izvi zvinoreva zvakare kuti rimwe rega revhidhiyo (mumutsetse wega 30 nechiratidzo chechipiri) rinodzokororwa kaviri pamakumi matanhatu nerimwe rechipiri. Nokutarira mathemati, munhu anogona nyore kuona kuti mamwe mafiramu anotarisa anorevei kune mamwe maitiro ekuvandudza.
Frame Rate vs Refresh Rate
Chii chinoita kuti zvinhu zvivhiringidze pfungwa yekuti zvikamu zvakasiyana zvakasiyana uye zvakangwara zvinoratidzirwa rwechipiri chese, zvichienderana nekuti kangani nguva firimu inodzokororwa imwe imwe neimwe / 24, 1/25, kana kuti 1 / 30th yechipiri kuti ienzanise nhamba yekuvandudza ye Terevhizheni inoratidza.
Terevhizheni dzine pikicha yavo inozorodza mano. Vhidhiyo yeTV yezororo rinowanzowanikwa mubhuku rekushandisa kana pane peji yemagetsi webhupu peji.
Nhamba yakawanda yekufambisa kwemaserevhizheni nhasi ndeye 60 Hz yeNTSC-based systems uye 50 Hz yePAL-based systems. Zvisinei, nekuiswa kwevamwe vatambi vechi Blu-ray Disc neHD-DVD vanogona kubudisa mamiriro makumi maviri nemasere pirigiramu yemavhidhiyo yechipiri, panzvimbo yehutori hwemhando 30 pamusana wevhidhiyo yemavhidhiyo, matsva matsva ekuvandudza ari kushandiswa nevamwe vanoita terevhizheni vanoita kuti agone zviratidzo izvi muchidimbu chechibalo chemasvomhu.
