Momwe mungalumikizire bwino bokosi lapamwamba la digito ndikukhazikitsa wolandila

Kulumikiza ndi kukonza bokosi lapamwamba la kanema wawayilesi sikuyenera kukhala vuto kwa wogwiritsa ntchito pophunzira mwatsatanetsatane komanso kutsatira mosamalitsa malangizo ndi malangizo atsatanetsatane omwe aperekedwa m’nkhaniyi.

Zida zofunikira zolumikizira bokosi la TV set-top: kuwunika kwamavidiyo

Kuti mutha kuwulutsa mumtundu wa digito pa TV yakale kapena yatsopano, mufunika kugula zida zina:

• seti-pamwamba bokosi ndi thandizo kwa mtundu DVB-T2 ;
• chingwe chodalirika chokhala ndi zolumikizira zoyenera;
• antenna yotumiza chizindikiro cha TV.

Bokosi lapamwamba (lolandila) la kanema wawayilesi wa digito

Kufunika kogula bokosi lapamwamba la digito kapena wolandila kumagona chifukwa zimathandiza kubisa chizindikiro cha TV cha digito chomwe chalandilidwa pa TV.

Makanema ena a TV opangidwa pambuyo pa 2012 ali kale ndi chochunira cha digito monga momwe zimakhalira. Izi zimathetsa kufunika kogula cholandila chowonjezera – mutha kuyamba kukonza antenna nthawi yomweyo.

Ngati TV ilibe chochunira digito, pamakhala kofunikira kugula bokosi lakunja lapamwamba. Mtundu wolandila uyenera kuganizira zochepera zomwe zili mulingo waposachedwa:

1. Kutha kuthandiza DVB-T2 . Zitsanzo zapa TV zitha kukhala ndi chochunira cha digito cha mtundu wakale wa DVB-T polandila chizindikiro cha TV, koma iyi ndi mtundu wakale ndipo sichingakhale yoyenera m’mikhalidwe yatsopano.
2. Kukhalapo kwa chithandizo cha kanema mumtundu wa mp4 . Imakulolani kusewera makanema apamwamba kwambiri.

Bokosi lapamwamba litha kupatsidwa zina zowonjezera zoyenera kwa ogwiritsa ntchito polumikiza ma TV akale kwa wolandila:

1. Kukhalapo kwa USB . Kukhalapo kwa cholumikizira ichi kumathandizira kulumikiza flash drive ndi makanema kwa wolandila kuti awonere pa TV yayikulu. Pankhaniyi, palibe chifukwa cholumikizira intaneti.
2. Pulogalamu yoyimitsa kuwulutsa kwa TV panthawi yowulutsa pompopompo ndikujambulitsa pa hard drive kuti muwonekere pambuyo pake.
3. Thandizo lolumikizira ku rauta . Ndizotheka kulumikiza pogwiritsa ntchito Wi-Fi kapena kudzera pa LAN (mawaya).
4. Opaleshoni System Android . Chifukwa cha pulogalamuyi, TV yakale yakunyumba ikhala yokwanira kupanga malo osangalatsa a multimedia.

Pogwirizanitsa zipangizo zamakono zamakono zamakono , palibe chifukwa chowonjezera ndalama zogulira bokosi lokwera mtengo kwambiri, chifukwa TV idzakhala ndi machitidwe ake ogwiritsira ntchito. Izi zimapangitsa chipangizochi kukhala pakati pa multimedia. Zikatere, wailesi yakanema ya digito ipezeka ngakhale ndi mlongoti wotchipa womwe umathandizira mtundu wa DVB-T2.
