Uyini imvamisa we-TV

Kasibili isiphi isiteshi sethelevishini abazalwa presents yeviyo umsakazo amaza esukela imitha noma decimeter amagagasi futhi lenzelwa ukudluliselwa image futhi umsindo amasignali. Kulesi zokugcina zilethwe umthengi noma ikhebula opharetha amasevisi noma nge ukusakaza nge-satellite, ngabanye noma antenna ngokuhlanganyela.

Kuyini ukuvama isiteshi se-TV

Ithelevishini isiteshi amaza - uhlobo ecacisiwe izixhumanisi idivayisi transceiver okuyinto ahlelwe ngqo imishini ezokuxhumana. Lokhu Lidlulisela uthumela isignali digital ukuze kungaphefumuli eyamukelayo oguqula bayifaka isithombe kusikrini se-TV. Kubalulekile ukuqaphela ukuthi opharetha iziteshi zokusakaza off emoyeni ngokwakho ikhebula inethiwekhi yayo, futhi uma kudingeka, kalula ukushintsha ukuvama iziteshi TV. Ngenxa yalesi sizathu-ke kubaluleke kakhulu ukwazi izixhumanisi esiqondile transceiver. Lokhu kuzosiza umsebenzisi ukumisa izinhlelo ezidingekayo ngokushesha futhi ngendlela efanele, futhi engakutholi obuntofontofo kuzo. Izimo yokugcina kuhlobene yokuthi amaza isiteshi sethelevishini ezindaweni ezahlukene zingahluka.

imvamisa isiteshi se-TV: Izici Key

Omunye izici ezibaluleke kakhulu kulokhu uhla, ebalulwe GHz. Ngokwesibonelo, ukubaluleka eziyinhloko imvamisa lesizinda esiphelweni «Ku» kamabonakude satellite «C». Lesi sakamuva isetshenziswa ngokuyinhloko ezimotweni amadala. Ibanga «Ku» yena, namuhla a yesimanje ezokuxhumana kumadivayisi ezinkulu kanti esetshenziswa kabanzi. Njengoba kushiwo ngaphambili, no-opharetha ngamunye ngezikhathi ukushintsha imvamisa isiteshi, okufaka imvamisa iziteshi digital ithelevishini, okuyinto luhambisana nomthwalo olubekhona ekutholeni amadivayisi nemingcele entsha.

Ukubeka amaza isiteshi se-TV

Ezimweni eziningi, umshini owamukelayo isignali angase ngokuzenzekelayo vulela iyiphi ether ukusakaza. Lokhu kudinga ukuba unikeze kuphela amandla owamukelayo kanye TV, bese ucindezela ku-elawulwa kude noma iyiphi inkinobho inombolo. I umamukeli angeke uhambe ngokuzenzakalelayo ibe "isiteshi scan" Imodi futhi ngokuzimela ukukhethela kordinaty edingekayo. Umsebenzisi kungaba kuphela ukugcina izinhlelo zethelevishini ngokungenanjongo imvamisa itholiwe futhi uqale ukujabulela okusezingeni eliphezulu ikhwalithi yesithombe.
