ʻAe wale nō i ka neʻeʻana o nā mea a pau mai nā hiʻohiʻona analog e like me nā hiʻohiʻona e makemake ai i nā lekiō kiʻekiʻe loa. He 16: 9 ōna hiʻohiʻona hiʻohiʻona, e like me ka nānāʻana i kahi kiʻi kiʻi kiʻiʻoniʻoni, a ke loaʻa nei iā lākou me nā pale hoʻonā kiʻekiʻe loa, nā mea e hoʻohālike me ka mālamalama, ka lanu, a me nā mea kiko'ī. ʻO ka hoʻolālā he mea kānaluaʻo ka HDTV nui nui loa.
He aha kaʻokoʻa o nā hopena?
Ma keʻano laulā,ʻo kaʻoi aʻe o ka hoʻonāʻana o kahi TV,ʻo kaʻoi aku ka maikaʻi o ke kiʻi a me ke kiʻekiʻe o ka helu uku. No laila, inā e kūʻai anaʻoe no kahi TV, ponoʻoe eʻike i ka hopena o ka manaʻo palekana a me nā mea āu e loaʻa nei no kāu kālā.
ʻO nā'ōlelo hoʻokūkū HDTV kūpono he 720p, 1080i, a me 1080p-ka helu no ka helu o nā laina e hana i ke kiʻi, aʻo ka leka e wehewehe ana i keʻano o ke kiʻi i hoʻohanaʻia e ka TV e hōʻike i ke kiʻi: holomua a iʻole e pākuʻi. ʻO ka hopena no nā mea e pili ana i nā laina hou. Heʻano like kēia i nā kiʻi pūnaewele a pehea e hoʻoholo ai ka dpi i ka maikaʻi o ka peʻa.
- 720p he hoʻolālā kiʻi o 1280 pixels ma 720 mau laina. 720p ka hopena o ka HDTV mua. Aia nō ia i kēia manawa aʻaʻole naʻe i maʻalahi e like me ka manawa ma mua i ka ihoʻana o nā kumukūʻai ma nā 1080 TV. Ma ka hoʻohālikelike, heʻelua manawa o ka wikiwiki 720p o kahi kiʻi analog TV.
- 1080i he hoʻonāʻana o 1920 mau pika me 1080 laina laina. Eia naʻe, ua pākuʻiʻia i penaʻia nā laina i ka nānā ma nāʻaoʻaoʻelua o 540 laina i kēlā me kēia. Hiki maikaʻi kaʻilikai kiʻi no ka hoʻolōʻihi i nā mea āpau aʻaʻole naʻe e like me ka mea e makemakeʻia ana no nā mea wikiwiki. ʻO 1080i ka pahuhopu i nā HDTV akāʻaʻole'ē aʻe. ʻAʻole iʻoi aku kona maikaʻi ma mua o nā 720p TV.
- Loaʻa i ka helu 1080p o ka 1920 e 1080 pixels, a he'ōleka holomua,ʻaʻole i pili, no laila e hāʻawiʻia ke kiʻi me kahi 2.07 miliona pika. ʻO kēia keʻano o ka hōʻailona kūʻai nui loa o ka TV a hāʻawiʻia i keʻano maikaʻi loa o nā hiʻohiʻonaʻekolu i hōʻikeʻia maʻaneʻi.
ʻO wai ka hōʻailona HDTV iʻoi aku ka maikaʻi-720p, 1080i a iʻole 1080p?
Ke manaʻo neiʻo ia i kēia mau hōkeo TVʻekolu ma kāu ke kumukūʻai,ʻo ka 1080p TV ka koho maikaʻi . ʻO ka 720p a me 1080i nāʻenehana kahiko e hoʻonanea ana i nā TV pāʻani kiʻekiʻe. Hāʻawiʻo ia i kaʻike maikaʻi loa a me ka nānāʻana, a ua nui ka 1080p mau mea i waho ma laila. Eia naʻe, inā e kūʻai anaʻoe i kahi TV i 32 mau 'īniha a iʻole liʻiliʻi,ʻaʻoleʻoe eʻike i ka likeʻoleʻana o nā kiʻi ma nā kiʻi 1080p a me 720p.
ʻO ka Future o ke Kūlana Kiʻekiʻe Loa
ʻAʻole kū mālie kaʻenehana, no laila eʻikeʻoe i kekahi mau TV hoʻonā kiʻekiʻe loa ma ka mākeke. Ua puka mai nā 4K TV i kēia manawa, aʻaʻole e lōʻihi ma mua o ka hikiʻana o nā papa he 8K. Ināʻaʻoleʻoe i kaʻokiʻana i kaʻenehana, he mea nui ia iāʻoe-aʻo kāu hōʻemi hoʻonuiʻole-ʻo ka UHD (ultra high definition)ʻaʻole pono ke kūʻaiʻia i kēia manawa no ka mea,ʻaʻohe nui o nā mea e hiki ai iā lākou ke kiʻekiʻe nā hopena.
- 4K UHD : Aia 4K mau wikiō i kēia manawa, akā, he mea kūʻai. Aia i kēia mau TV he 3840 pika i nā laina 2160.
- 8K UHD : Aia ma hope o ka wāwae o 4K, 8K UHD e hiki koke mai. ʻAʻole hiki ke loaʻa nā waihona no 8K TV. Hāʻawi nā 8K TV i 7680 pixels e kahaha nei ma nā laina 4320.
No ka Wide-Screen Benemua
ʻO ka hoʻomaikaʻi houʻana o nā HDTV ma luna o nā analog TV,ʻo ia ka pākea nui ma mua o ka pākuhi. ʻO ke kiʻi ākea ka mea maikaʻi no ko mākou mau maka - keʻike nei mākou i nā kiʻi ākea ākea o nāʻaoʻao ākea ma mua o ka hōʻailona kūlahi o ka analog TV. ʻO ko mākou mau maka ke nānā maikaʻi mai ka hema a me ka pololei ma mua aʻe ma luna a hiki i lalo. Hiki i ka 'ākea ke hōʻike i nā meaʻoi aʻe o ka nānā, kahi nui no nā hāmeʻa a me nā kiʻiʻoniʻoni. Loaʻa i nā HDTV a pau ka lālā o ka hiʻohiʻona ākea, no lailaʻaʻole kēiaʻano hoʻonui iʻoi aku ka maikaʻi o ka wikiō.
