Chinhu chikuru. Yakakura kupfuura iwe yaunofungidzira kana iwe uchifunga zvinorehwa. Zvikazo, kana zvakadaro, hauna kunyatsoteerera, digital migration ishanduko kubva paanalogue TV kuenda kudhijitari yeterrestrial TV kutepfenyura, idzo nyika dzepasi rose dzinotarisirwa kutora. Zvakauya sei?
In 2006, member countries of the International Telecommunication Union (ITU), in Geneva, Switzerland, signed an agreement to move from analogue to digital broadcasting by June 2015, the deadline for Digital Switch Over (DSO). Nigeria, for a variety of reasons, did not meet the deadline and has set another one for June 2017.Kutama kwedhijitari kunosanganisira kufambiswa kwemasaini eterevhizheni edhijitari pamusoro penyika kubva kumaseti kuenda kune vanogamuchira kumba.. Kana DSO ikaitika, muoni weTV anozoda kuva ne-set-top box (STB) kana kushandisa dhijitari TV kuti ugamuchire masevhisi eterevhizheni. A Set-Pamusoro Bhokisi ndiyo inowanzonzi decoder. Nekuwana Set Top Bhokisi rinoenderana neDVB-T2, tekinoroji yechizvarwa chechipiri (analogue inoshandisa iyo DVB-T kana T-1 siyana), uine kana usina kunyorera pamwedzi kana nedhijitari terevhizheni, muoni weterevhizheni achakwanisa kugamuchira chiratidzo kana DSO ichiitika, zvichitevera kudzimwa kweanalogue. Izvi zvinoreva kuti muoni haakwanisi kuona terevhizheni yeanalogue kana asati atama.. Kana iwe uchida kuramba uchiona TV kana DSO ikaitika, uchafanira kutenga Yemahara-ku-Air STB/decoder (kutenga-kamwe chete uye hapana kunyorera pamwedzi), Iyo Yakabatanidzwa Digital Terevhizheni seti kana inobhadhara-TV STB/decoder (izvi zvinouya nekunyoreswa kwepamwedzi). DVB (Digital Vhidhiyo Nhepfenyuro) ndiyo chiyero cheterevhizheni yedhijitari yakagamuchirwa munyika zhinji muITU Dunhu 1, uko Africa inowira. DVB-T, iyo inomirira Digital Vhidhiyo Broadcasting Terrestrial, ndiyo yekutanga DVB chiyero chiri kutsiviwa neDVB-T2. DVB-T2 inomirira Digital Video Broadcasting (Chizvarwa chechipiri cheTerestrial), hurongwa hutsva hunopa rubatsiro rwekushanda kwepamusoro-soro uye kushanda kwepamusoro. DVB-T2 haisi shure inowirirana DVB-T. Saizvozvo, DVB-T vanogamuchira havagoni kugamuchira DVB-T2 zviratidzo, uyewo DVB-T2 haigoni kugamuchira zviratidzo zveDVB-T. Izvi zvinoreva kuti vagari vemunyika umo kutama kunonzi kwave kuwanikwa muna Chikumi 2015 deadline, asi paT-1 tekinoroji ichafanira kutenga DVB-T2 vanogamuchira vanotsigira iyo DVB-T2 chiyero.. Kusarudza chiratidzo chedhijitari nhepfenyuro, munhu anoda kuva ne digital TV. Digital TV iTV ine inbuilt digital tuner. Asi kana mumwe achine analogue TV, mumwe achada kuwana dhijitari inogamuchira muchimiro cheseti-yepamusoro bhokisi, iyo inoshandura masaini kubva kuterevhizheni yedhijitari kuita fomu inogona kutariswa pane yechinyakare analogue terevhizheni. Izvi zvinoreva here kuti tave kubhadhara kuti titarise machannel atanga tichiwana pachena pasi petepfenyuro yepasi? Kune marudzi maviri emapaketi ebasa rekutepfenyura papuratifomu yepasi: i.e.. Yemahara-kumhepo uye Pay TV. Iwo Mahara-ku-Air chiteshi ndeaya aunogamuchira usingabhadhare kana kubhadhara muripo wepamwedzi kuti ugamuchire. Nhepfenyuro idzi dzicharamba dzakasununguka kunyange mushure mekutama kubva mukutepfenyura kweanalogue kuenda kudigital. Pay-TV inoda kuti unyore uye ubhadhare mari yekunyoresa kuti utarise chiteshi chakabatana seDStv kana GOtv.. In analogue kutepfenyura, chiratidzo chinofambiswa semafungu anoenderera, nepo kutumirwa kwedhijitari kunosanganisira kutapurirana kwechiratidzo sedhizaini. Ye digital TV, iyo siginecha yakavharirwa uye inogona kudzvanywa kuti ibvumire mamwe machanera kutepfenyurwa. Digital migration inopa huwandu hukuru hwezvikamu kupfuura analogue. Kune imwe, inova nechokwadi chemhando yepamusoro yekuona uye inopa mamwe masevhisi seredhiyo, Teletext, interactive services, mitambo, nerutsigiro rwevasingaoni neinternet. Pamusoro pe, inobvumira kugovaniswa kwezvivakwa kuburikidza nekushandisa masaini ekuparadzira masisitimu uye inopa mikana mikuru yezvakawanda zvemukati kugadzirwa zvemukati., izvo zvinopa mikana yebasa yakawanda kune vanogadzira zvemukati. Nenzira iyoyo, inobetsera nenzira isiri duku kugarikano youpfumi hwenyika dziri kutama.
