Naphezu kokuthuthuka okusheshayo kwamadivayisi ahlakaniphile afana nomakhalekhukhwini, i-TV isewumshini kagesi odingekayo emindenini, futhi isilawuli kude, njengemishini yokulawula ye-TV, ivumela abantu ukushintsha iziteshi ze-TV ngaphandle kobunzima.
Naphezu kokuthuthuka okusheshayo kwamadivayisi ahlakaniphile afana nomakhalekhukhwini, i-TV iseyinto edingekayo kagesi emindenini.Njengemishini yokulawula ye-TV, abantu bangashintsha kalula iziteshi ze-TV.Ngakho-ke isilawuli kude sikubona kanjani isilawuli kude se-TV?
Ngokuqhubeka kobuchwepheshe, izinhlobo zezilawuli kude ezingenazintambo nazo ziyakhula.Ngokuvamile kunezinhlobo ezimbili, enye iyiremote ye-infrared, enye i-radio shake mode.Ezimpilweni zethu zansuku zonke, esetshenziswa kakhulu imodi yesilawuli kude se-infrared.Sithatha isilawuli kude se-TV njengesibonelo, ake sikhulume ngomgomo wayo wokusebenza.
Isistimu yesilawuli kude ngokuvamile yakhiwa i-transmitter (isilawuli esikude), isamukeli neyunithi yokucubungula emaphakathi (CPU), lapho umamukeli ne-CPU ziku-TV.Isilawuli kude se-TV esijwayelekile sisebenzisa i-infrared ray enobude begagasi obungu-0.76 ~ 1.5 microns ukuze sikhiphe ulwazi lokulawula.Ibanga layo lokusebenza lingamamitha angu-0 ~ 6 kuphela futhi lisakazeka ngomugqa oqondile.Kumjikelezo wangaphakathi wesilawuli esikude, esihambisana nokhiye ngamunye kusilawuli esikude, isifunda sangaphakathi sisebenzisa indlela ethile yokubhala ikhodi ukuze ihambisane naso.Uma ukhiye othize ucindezelwa, isifunda esithile sesekethe sixhunyiwe, futhi i-chip ingakwazi ukubona ukuthi iyiphi isekethe exhunyiwe futhi ihlulele ukuthi yimuphi ukhiye ocindezelwe.Bese, i-chip izothumela isignali yokulandelana kwekhodi ehambisana nokhiye.Ngemva kokukhulisa nokushintshashintsha, isignali izothunyelwa ku-diode ekhipha ukukhanya futhi iguqulelwe kusignali ye-infrared ukuze ikhiphe ngaphandle.Ngemva kokuthola isignali ye-infrared, umamukeli we-TV uyayidiliza futhi ayicubungule ukuze abuyisele isignali yokulawula, futhi athumele isignali kuyunithi yokucubungula emaphakathi, eyenza imisebenzi ehambisanayo njengokushintsha amashaneli.Ngakho, siyaqaphela umsebenzi wokulawula kude we-TV.
Isilawuli kude se-infrared sinezinzuzo eziningi.Okokuqala, izindleko zesilawulikude se-infrared ziphansi futhi kulula ukwamukelwa ngumphakathi.Okwesibili, isilawuli kude se-infrared ngeke sithinte indawo ezungezile futhi ngeke siphazamise ezinye izinto zikagesi.Ngisho nemishini yasendlini ezindlini ezahlukene, singasebenzisa uhlobo olufanayo lwesilawuli kude, ngoba isilawuli kude se-infrared asikwazi ukungena odongeni, ngakho-ke ngeke kube khona ukuphazamiseka.Okokugcina, ukulungiswa kwesifunda sesistimu yokulawula kude kulula, ngokuvamile singayisebenzisa ngaphandle kokulungisa iphutha, inqobo nje uma sixhuma ngendlela efanele ngokuvumelana nesifunda esicacisiwe.Ngakho-ke, isilawuli kude se-infrared sisetshenziswe kakhulu ezintweni zethu zikagesi zasendlini.
Ngokufika kwenkathi yobuhlakani, imisebenzi ye-TV iya ngokuya ihlukahluka, kepha isilawuli kude siya ngokuya silula.Awekho izinkinobho eziningi kakhulu ngaphambili, futhi ukubukeka komuntu.Kodwa-ke, noma ngabe ikhula kanjani, isilawuli kude, njengesisetshenziswa sikagesi esibalulekile sokusebenzisa ikhompyutha yomuntu, kumele singabuyiseleki.
