Fahamka Ultra HDTV
Ultra HDTV, oo sidoo kale loo yaqaan 4K TV, waa nooc telefishin ah oo leh xallin ka sareysa HDTV-yada caadiga ah. Halka HDTV-yadu ay leeyihiin xallinta 1920x1080 pixels, Ultra HDTV-yadu waxay leeyihiin xallinta 3840x2160 pixels, taas oo macnaheedu yahay inay soo bandhigi karaan afar jeer in ka badan HDTV-yada.
Tani waxay keenaysaa sawir fiiqan oo faahfaahsan, gaar ahaan shaashadaha waaweyn.
Ultra HDTV-yadu waxay sidoo kale inta badan leeyihiin astaamo kale oo horumarsan, sida kala duwanaansho firfircoon (HDR) iyo gamut midab ballaadhan, taasoo kor u qaadi karta khibradda daawashada.
Ultra HDTV waa tignoolajiyada telefishin ee qeexan oo bixisa afar jeer xallinta muuqaalka telefishanka caadiga ah. Waxa kale oo loo yaqaan 4K UHD, maadaama ay leedahay xallinta 3840 x 2160 pixels.
Tani waxay ka dhigan tahay in sawirku yahay mid fiiqan oo faahfaahsan, taas oo u oggolaanaysa waayo-aragnimo daawasho badan.
Intaa waxaa dheer, qaar ka mid ah moodooyinka Ultra HDTV waxay sidoo kale bixiyaan teknoolojiyad dheeri ah sida HDR (kala duwanaansho firfircoon oo sarreeya) iyo qiime cusub oo cusub, taasoo sii kordhinaysa tayada sawirka.
Ultra-HDTV, oo sidoo kale loo yaqaan 4K UHD, waa nooc ka mid ah tignoolajiyada soo bandhigista telefishinka oo bixiya xallinta 3840 x 2160 pixels, taas oo afar jeer ka ah 1080p Full HD. Tani waxay ka dhigan tahay in Ultra-HD TV-yadu ay soo bandhigi karaan tafaasiil iyo muuqaalo ka sii fiican marka loo eego HDTV-yada caadiga ah.
Marka lagu daro xallinta sare, Ultra-HD TV-yadu waxay inta badan leeyihiin sifooyin kale oo horumarsan sida kala duwanaansho firfircoon (HDR) iyo gamut midab ballaaran, taas oo sii wanaajisay khibradda daawashada.
Telefiishanka Qeexida aadka u sarreeya waa tignoolajiyada telefishan oo bixisa xalin sare iyo tayada muuqaal ka wanaagsan ta telefishin dhaqameedka heerka sare ah. Waxaa caadi ahaan loo yaqaan 4K ama 8K telefishan, taas oo macnaheedu yahay inay leeyihiin cufnaanta pixel sare marka loo eego telefishanka qeexan sare.
Telefishinada 4K caadi ahaan waxay leeyihiin 3840 x 2160 pixels, halka telefishinada 8K ay leeyihiin 7680 x 4320 pixels.
Telefishinadan waxay isticmaalaan tignoolajiyada bandhig ee horumarsan sida OLED ama QLED si ay u bixiyaan isbarbardhig ka wanaagsan iyo midabka midabka.
Telefishinada qeexitaankoodu aadka u sarreeyaa waxay u baahan yihiin xawaarahooda xawaaruhu sarreeyaan iyo xawaareynta processor-ka si ay xog badan uga baaraandegaan si ay u bixiyaan xallin sare iyo tayada muuqaal wanaagsan.
