Sesebelisoa sa A / B ke thepa ea thelevishene e thusang haholo ho lumella lisebelisoa tse peli tsa RF (radio frequency) / coaxial hore li hokahane ho kenyelletso e le 'ngoe ea RF / coaxial. E lumella hore u fetole pakeng tsa lipontšo tse peli tsa coaxial ho bonts'a sehlabelo se le seng. Ka lihlahisoa tsa RF ho e-na le lihlahisoa tse tharo tse nang le mebala ea RCA , e kopana le cable ea 75 Ohm.
Liphetoho tsa A / B li fapana ka mokhoa; tse ling li na le li-casing tse bonolo, tsa tšepe, ha tse ling li le polasetiki tse nang le matla a ho laola.
Liphetoho tsa A / B li sebelisoa joang?
Mona ho na le maemo a mararo a tloaelehileng ao u ka sebelisang phetolelo ea A / B:
- U na le HDTV, ngolisa cable ea analog, 'me u sebelise antenna. Kaha boholo ba HDTV bo na le tlatsetso e le 'ngoe ea RF, u tla hloka phetoho ea A / B ho kopanya thaba ea analog le antenna ho kenya RF ho HDTV . Phello e ne e tla ba bokhoni ba ho fetola lipontšo tse peli tsa RF ntle le ho thibela lisebelisoa.
- O na le DTV ea analog mme o sebelisa DTV converter, antenna le VCR. U batla ho tsoela pele u shebeletse TV mocha o mong ha VCR e tlaleha ka e 'ngoe. Kaha ho na le converter ea DTV e laolang letšoao le kenang ho VCR, u tla hloka lisebelisoa tse peli ho etsa hore sena se etsahale: phetoho ea A / B le sekhahla. Kopanya antenna ho e arohaneng, e arohanang karolo e le 'ngoe ho tse peli. Likhoele tse peli li tsamaea litseleng tse fapaneng ho fihlela li kopane hape ho chencha A / B. Bala ho eketsehileng ka boemo bona .
- O batla ho shebella mehloli e 'meli ea lik'hamera ka ponts'oa e le' ngoe ea ho shebella. Khamera e hlahisitsoe ke RF, kahoo o hloka khalase ea coaxial. Pontšo ea ho shebella e na le letsoho le le leng feela la coaxial. Kopanya k'hamera e 'ngoe le e' ngoe ho A / B e le hore u ka fetola pakeng tsa kamera ea pele le ea bobeli.
