Utshintshi lwe-A / B luncedo oluthe luncedo kakhulu kumabonwakude olwenza iiRF ezimbini (ii-frequency zomsakazo) / ii-coaxial zixhobo ukudibanisa kwi-RF eyodwa / coaxial input. Ikuvumela ukuba uguqule phakathi kweempawu ezimbini ezihlukeneyo ze-coaxial kwisiboniso esisodwa sokubukela. Ngeziphumo ze-RF kunokuba zifakelwe izixhobo ezintathu ze- RCA , zixhuma kwi-cable-75 Ohm.
Utshintshi lwe-A / B luhluke kwisitayela; Ezinye zilula, i-metallic casings, kanti ezinye iiplastiki ezikwazi ukulawula ukude.
Ukutshintshwa kwe-A / B Kusetyenziswa njani?
Nazi izinto ezintathu eziqhelekileyo apho ungasebenzisa ukutshintsha kwe-A / B:
- Unayo i-HDTV, ubhalisele kwikhebula le-analog, kwaye usebenzise i-antenna. Ekubeni ama-HDTV amaninzi anegalelo elilodwa le-RF, kufuneka uguqule i-A / B ukuxhuma i-analog cable kunye ne-antenna kwi-input ye-RF kwi- HDTV . Isiphumo siyakwazi ukuguqula phakathi kweempawu ezimbini zeRF ngaphandle kokunqamula iicingo.
- Unayo i-analog DTV kwaye usebenzise umguquleli we-DTV, i-antenna kunye neVCR. Ufuna ukuqhubeka ubukela iTV kwikane enye ngelixa iVCR irekhoda kwenye. Ngenxa yokuba umguquli we-DTV ulawula isangeniso esingenayo kwi-VCR, unokwenene ufuna iifowuni ezimbini ukwenzela ukuba kwenzeke oku: ukutshintsha kwe-A / B kunye ne-splitter. Xhuma i-antenna kwi-splitter, eyahlula igalelo elinye kwizinto ezimbini. Iimbalo zombini zihamba ngeendlela ezihlukeneyo kude zidibene kwakhona kwi-A / B. Funda kabanzi malunga nale meko .
- Ufuna ukubeka esweni iifayile ezimbini zekhamera kwisiboniso esisodwa sokubukela. Imveliso yekhamera yiRF, ngoko ufuna ikhebula coaxial. Umboniso wokubukela unomnikelo owodwa we coaxial. Xhuma nganye ikhamera kwi-A / B ukuze utshintshe phakathi kwekhamera yokuqala kunye neyesibini.
