Kule ndaba, kuyacaca kuyinto umbuzo kanjani ukukhetha umamukeli. Ukuze uthenge ungazange ukudanisa, kubalulekile ukufunda wonke umehluko wemisindo nemiqondo yamagama.

Kungani udinga umlinganisi?

Receiver - msindo multi-umzila nge decoders digital alalelwayo video ukusakaza. Ngaphambili, lapho ezivamile babe CRT TV, Analogue yezokusakaza u - Imininingwane badlula eseduze ithelevishini umbhoshongo. Ngokuba abanjalo "teleyaschika" izinga isignali eyamukelekayo eyanele ukuthola kancane eliphezulu isithombe ngaphezulu noma.

Okwesibili, ulwazi waqala ukumela ikhodi kanambambili - ". Ithelevishini digital" amadijithi 0 no 1. Ngakho, igama elithi Konke lokhu kwakudinga kudalwa yezokusakaza ubuchwepheshe obusha - digital, elikwaziyo ukuncela odlala kuphela.

Indlela ukukhetha umlinganisi?

Okwamanje, ethandwa kakhulu futhi inzuzo kuyinto digital TV Isamukeli DVB-T2 format. yesimanje "teleyaschika" kukhona kakade imishini kakhulu esakhelwe yalolu hlobo. onobuhle okunjalo ziphawulwe logo - isifinyezo DVB-T2 kudivayisi ngokwayo noma ebhokisini noma butterfly isithombe. Kuzo zonke ezinye izimo kuyodingeka ukuthola imishini eyengeziwe. Uma ukhetha i-main Isiqalo sedijithali yayo ishidi idatha, kwaboniswa ukuthi kuthatha ncamashi ifomethi DVB-T2, kwazise ziningi eziningana esezikhulile yezokusakaza ubuchwepheshe (DVB-C, DVB-T, DVB-S). Ngaphezu kwalokho, qiniseka ukuthi imishini asekelwe ifomethi ye-MPEG-2 kanye-MPEG-4 - izindlela eziyisisekelo sezihambile kwevidiyo isethulo. Lawa ehilelekile ezimbili ezibaluleke kunazo zonke lapho kudingeka uqiniseke ngaphambi kokuthenga.

Paid noma iziteshi zamahhala?

Kumele kukhunjulwe ukuthi ikhadi ezithile ukunika ukufinyelela kuphela eziteshini ezithile. Uma uhlela isikhathi ukushintsha umhlinzeki futhi kwenziwe kutholakale ukuze ubuke ezinye iziteshi ezikhokhelwayo, kufanele uthole umamukeli ifakwe slot for CI mojuli. Kulokhu, ungenalo ukushintsha isiqalo njalo, ngokushesha ngangokunokwenzeka ukuthenga ukubhalisa entsha. Uma ungazizwa like ukukhokha imali ukubukwa iziteshi yangasese TV, ukuthenga owamukelayo sedijithali TV ngaphandle kwalezi amamojuli. Izindleko ezinjalo amabhokisi set-top ngenxa yesizathu esisodwa noma ezimbili ayizinkulungwane ngezansi.

Ukuba khona interface

Ukuba khona nezixhumi ezengeziwe, ezifana USB, E-the sata, Sata noma yocezuningi, ungakwazi ukwandisa ukusebenza aduduze uthenge wena. Ukuze unqume ukuthi izixhumi ewusizo ezengeziwe ukunikela ufunde sinako abakudingayo:

• -USB isetshenziswa ukuxhuma flash ngemoto, omakhalekhukhwini kanye namanye amadivayisi ngokusebenzisa i-USB ikhebula ngqo umamukeli. Ngokuvamile, lezi aduduze ungadlala umculo, amavidiyo kanye nezinye amafayela kusuka yenethiwekhi yakho.
