1080p thiab Blu-duab Disc Players
Nco ntsoov tias ntawm Blu-Ray, cov ntaub ntawv ntawm lub disc yog nyob rau hauv 1080p / 24 hom ntawv (Ceebtoom: Muaj qee cov qauv ntawm cov ntsiab lus muab tso rau hauv Blu-ray disc nyob rau hauv 720p / 30 lossis 1080i / 30, tab sis cov muaj kev zam, tsis yog txoj cai). Feem ntau cov Blu-ray Disc players muaj peev xwm tawm tau 1080p / 24 rau ib lub TV uas tau tshaj nyob hauv daim ntawv sau ua haiv.

Txawm li cas los xij, muaj ntau yam kev hloov ntawm qee cov players ua tiav txoj hauj lwm no. Cov nram qab no yog ob qho kev nthuav tswv yim yav dhau los los ntawm ob tug neeg uas tsis nyob rau hauv ntau lawm tiam sis tseem siv tau.
Thawj tus qauv yog cov LG BH100 Blu-duab tshav / HD-DVD combo player (tsis ntev lawm) . Txij li, thaum lub sij hawm ntawm nws tso, tsis yog txhua tus HDTVs yuav tso saib 1080p / 24, thaum LG BH100 txuas nrog HDTV uas tsis muaj 1080p / 24 tawm tswv yim thiab tso tawm muaj peev xwm tab sis tsuas yog muaj peev xwm 1080p / 60/30 los yog 1080i muaj peev xwm , LG BH100 yuav xa nws 1080p / 24 teeb liab los ntawm lub disc mus rau nws tus kheej video processor uas ces outputs ib lub teeb liab 1080i / 60. Nyob rau hauv lwm yam lus, tus neeg ua si no tsuas yog tsim tawm 1080p teeb liab yog tias TV yog 1080p / 24 tshaj.

Txawm li cas los xij, yog tias nws pom tias HDTV tsis tuaj yeem ntsuas 1080p lub teeb liab, Samsung BD-P1000 tsuas yog siv nws tus kheej tsim 1080i lub teeb liab thiab kis tawm cov teeb liab los ntawm HDTV, cia lub HDTV ua lwm yam kev ua.
Cia li nrog LG BH100 yav dhau los. Qhov kawg 1080p zaub hom nyob ntawm seb qhov deinterlacing processor yog siv los ntawm lub HDTV rau lub kauj ruam kawg. Qhov tseeb, nyob rau hauv Samsung rooj plaub, nws yuav hais tias ib HDTV meej tau zoo dua 1080i-rau-1080p deinterlacer tshaj li Samsung tau, nyob rau hauv cov ntaub ntawv twg koj yuav pom zoo tshwm sim siv lub deinterlacer ua rau hauv HDTV. Qhov tseeb, nyob rau hauv Samsung rooj plaub, nws yuav hais tias ib HDTV meej tau zoo dua 1080i-rau-1080p deinterlacer tshaj li Samsung tau, nyob rau hauv cov ntaub ntawv twg koj yuav pom zoo tshwm sim siv lub deinterlacer ua rau hauv HDTV.
