Shanduro yeA / B inobatsira chaizvo kutengesa terevhizheni inobvumira maRF maviri (redio frequency) / coaxial madivayiri kuti aungane kune rimwe RF / coaxial input. Iko inokubvumira kushandura pakati pezviratidzo zviviri zvakasiyana zvakasiyana-siyana pamusana pekuona kuratidzwa. NeRF maitiro panzvimbo pematatu mavara-akaiswa maRCAs , inosanganiswa ne 75-Ohm cable.
A / B kushanduka kunosiyana mumutauro; vamwe vane nyore, metallic casings, asi vamwe vari mapurasitiki nechekudzivirira masimba.
Ko A / B Inoshandiswa Sei?
Heano zvinhu zvitatu zvinowanzoitika maungashandisa kuchinja kweA / B:
- Iwe une HDTV, nyora kubhadharo yeAnalogog, uye shandisa antenna. Sezvo vazhinji vane HDTV vane ruzivo rumwe rweRF, iwe unoda kuchinja kweA / B kuti ubatanidze cable yeanalog uye antenna kusvika kuRF kupinda paHTTV . Chigumisiro chaizova kukwanisa kuchinja pakati pezviratidzo zviviri zveRF pasina kubvisa cables.
- Iwe une DTV yeAnalogo uye unoshandisa DTV converter, antenna, uye VCR. Iwe unoda kuramba uchiona TV pane imwe kero apo VCR inonyora pane imwe. Tichifunga kuti DTV converter inodzora signal inosvika kuVCR, iwe unotofanira kunyanya zvinhu zviviri kuti izvi zviitike: kuchinja kweA / B uye kuparadzanisa. Gadzirai antenna kune anoparadzanisa, iyo inoparadzanisa imwe nzira muzvikamu zviviri. Tsamba idzi mbiri dzinoenda munzira dzakasiyana kusvikira dzasanganiswa paA / B switch. Verenga zvakawanda pamusoro penyaya iyi .
- Iwe unoda kutarisa mapikicha maviri ekamera pane kuratidzwa kumwe chete kuratidzwa. Iko kamera yakabuda ndeye RF, saka unoda kanda coaxial. Chiratidziro chinotarisa chinongova chete coaxial input. Unganidza kamera imwe neimwe kuA / B yekuti iwe unogona kuchinja pakati pekutanga kera uye yechipiri.
