Nangona uphuhliso olukhawulezayo lwezixhobo ezihlakaniphile ezifana neefowuni eziphathwayo, iTV isesona sixhobo sombane esiyimfuneko kwiintsapho, kunye nolawulo olukude, njengesixhobo sokulawula i-TV, ivumela abantu ukuba batshintshe iziteshi zeTV ngaphandle kobunzima.
Nangona uphuhliso olukhawulezayo lwezixhobo ezihlakaniphile ezifana neefowuni eziphathwayo, iTV isesona sixhobo sombane esiyimfuneko kwiintsapho.Njengesixhobo sokulawula umabonwakude, abantu banokuwatshintsha ngokulula amajelo kamabonwakude.Ke iremote control iluqonda njani ulawulo olukude lweTV?
Ngenkqubela phambili yetekhnoloji, iintlobo zolawulo olukude ezingenazingcingo nazo ziyanda.Kukho iindidi ezimbini, enye yi-infrared remote control, enye yimowudi yokulawula ukushukuma kwerediyo.Kubomi bethu bemihla ngemihla, eyona isetyenziswa kakhulu yimowudi yolawulo olukude lwe-infrared.Ukuthatha ulawulo olukude lweTV njengomzekelo, makhe sithethe ngomgaqo wayo wokusebenza.
Inkqubo yokulawula kude ngokubanzi iqulunqwe ngumthumeli (isilawuli esikude), umamkeli kunye neyunithi yokucubungula ephakathi (CPU), apho umamkeli kunye ne-CPU zikwiTV.Umlawuli okude we-TV jikelele usebenzisa i-infrared ray kunye nobude be-wavelength ye-0.76 ~ 1.5 microns ukukhupha ulwazi lolawulo.Umgama wayo wokusebenza yi-0 ~ 6 yeemitha kuphela kwaye isasazeke ngomgca othe ngqo.Kwisekethe yangaphakathi yolawulo olukude, oluhambelana nesitshixo ngasinye kwisilawuli esikude, isiphaluka sangaphakathi samkela indlela ethile yokurekhoda ukuhambelana nayo.Xa isitshixo esithile sicinezelwe, isiphaluka esithile kwisiphaluka sixhunyiwe, kwaye i-chip inokubona ukuba yeyiphi isiphaluka edibeneyo kwaye igwebe ukuba yiyiphi iqhosha eliciniweyo.Emva koko, i-chip iya kuthumela isignali yokulandelelana kwekhowudi ehambelana nesitshixo.Emva kokukhulisa kunye nokumodareyitha, isignali iya kuthunyelwa kwi-diode ekhupha ukukhanya kwaye iguqulelwe kwisignali ye-infrared ukuze iphume ngaphandle.Emva kokufumana isignali ye-infrared, umamkeli weTV uyayidiliza kwaye ayiqhubele ukubuyisela umqondiso wokulawula, kwaye ithumela umqondiso kwiyunithi yokucubungula ephakathi, eyenza imisebenzi ehambelanayo njengokutshintsha amajelo.Ke, siyawuqonda umsebenzi wolawulo olukude lweTV.
Ulawulo olukude lwe-infrared luneenzuzo ezininzi.Okokuqala, iindleko zolawulo olukude lwe-infrared zisezantsi kwaye kulula ukuba zamkelwe luluntu.Okwesibini, ulawulo olukude lwe-infrared aluyi kuchaphazela indawo engqongileyo kwaye aluyi kuphazamisana nezinye izixhobo zombane.Kwanakwizixhobo zendlu ezindlwini ezahlukeneyo, sinokusebenzisa uhlobo olufanayo lolawulo olukude, kuba ulawulo olukude lwe-infrared alukwazi ukungena eludongeni, ngoko ke akuyi kubakho ukuphazamiseka.Ekugqibeleni, i-remote control system yesekethe i-debugging ilula, ngokuqhelekileyo sinokuyisebenzisa ngaphandle kokuphazamiseka, nje ukuba sidibanisa ngokuchanekileyo ngokwesekethe echaziweyo.Ke ngoko, ulawulo olukude lwe-infrared lusetyenziswa ngokubanzi kwizixhobo zethu zasekhaya.
Ngokufika kwexesha elikrelekrele, imisebenzi yeTV iya isiba yintlupheko, kodwa ulawulo olukude luba lula ngakumbi.Akukho maqhosha amaninzi kakhulu ngaphambili, kwaye inkangeleko yenziwe ngabantu.Nangona kunjalo, nokuba iphuhla njani na, ulawulo olukude, njengesixhobo sombane esibalulekileyo ekusebenzisaneni kwabantu nekhompyuter, kufuneka ingabinandawo.
