Bokosi lapamwamba limakulitsa luso la TV. Ma TV akale sangavomereze zizindikiro za DVB-T2. Makanema amakono amawulutsidwa motere.

Pankhaniyi, ndikofunikira kulumikiza bokosi lokhazikika lomwe limatha kuzindikira chizindikiro cha digito ndikuchisintha kukhala analogi. Palinso mabokosi apamwamba a DVB-C ( chingwe TV ), DVB-S ( satellite TV ) ndi mabokosi apamwamba omwe ali ndi njira zophatikizira. Mabokosi a Smart set-top ( TV-Box ) ayenera kuikidwa m’gulu lapadera. Amatha kulumikiza TV iliyonse ku intaneti. [id id mawu = “attach_7346” align = “aligncenter” wide = “800”]

Kodi mukufunikira chiyani kuti mulumikize bokosi lapamwamba ku TV?

DVB-T2 ndi DVB-S2 seti-pamwamba mabokosi amafuna tinyanga ntchito molondola. Zofunikira ziyenera kuyang’aniridwa ndi alangizi kapena anthu omwe ali ndi chidziwitso ndi zipangizozi: khalidwe la chizindikiro limadalira malo, chiwerengero cha nyumba zapafupi, momwe tinyanga zimayendera ndi zina.

Kuchuluka kwa kutumiza kwa TV set-top box – chingwe

Mu zida, kuwonjezera pa seti-pamwamba bokosi palokha, inu mukhoza kuwona zingwe zingapo kulumikiza zosiyanasiyana TV. Mwachitsanzo, zidazo zitha kukhala ndi chingwe cha HDMI, RCA, SCART ndi S-Video Pa HDMI mawonekedwe pali mitundu ingapo:

1. HDMI 1.2 – imakupatsani mwayi wotulutsa chithunzi cha FHD.
2. HDMI 4 – imakupatsani mwayi wowonetsa zithunzi za 4K pamlingo wa 30fps.
3. HDMI 0 – imakupatsani mwayi wotulutsa zithunzi za 4K pamlingo wa 60fps.

HDMI ndi mawonekedwe a digito omwe amakulolani kulumikiza bokosi lokhazikitsira ku ma TV atsopano, komanso lili ndi mizere yozungulira yozungulira. Kwa ma TV akale, pali mawonekedwe a analogi a SCART, omwe amawoneka ngati cholumikizira chachikulu cha makona anayi, S-VIDEO, chomwe chimawoneka ngati cholumikizira chakuda chokhala ndi pulagi pakati ndi RCA, yomwe imawoneka ngati mitundu itatu yamitundu yambiri (yachikasu, yoyera ndi red) mapulagi a tulip.
