Isilawuli kude se-TV siyingxenye ebalulekile yeuhlelo lokuzijabulisa lwasekhaya, okuvumela abasebenzisi ukuthi baguqule kalula iziteshi, balungise ivolumu, futhi bazule kumamenyu.Manje okuyisisekelo emakhaya amaningi, irimothi ye-TV ihambe ibanga elide kusukela yasungulwa ngawo-1950s.Lesi sihloko sizocubungula umlando wesilawuli kude se-TV, sigqamisa ukuthuthukiswa kwayo okubalulekile futhi sihlole ukuvela kwayo kumarimothi ahlakaniphile anamuhla.
Izinsuku Zokuqala:I-TV yemishiniIzilawuli kude
Isilawuli kude sokuqala se-TV, esibizwa ngokuthi “Lazy Amathambo,” yethulwa nguI-Zenith Radio Corporationngo-1950. Lolu cingo lwaluxhunywe kumabonakude ngentambo ende, evumela abasebenzisi ukuthi bashintshe iziteshi futhi balungise ivolumu bekude.Kodwa-ke, ucingo olungemuva lwaluyingozi futhi lwaba yisixazululo esingalungile.
Ukubhekana nalolu daba,ZenithunjiniyelaEugene Polleyithuthukise i-“Flash-Matic,” isilawuli kude sokuqala se-TV esingenantambo, ngo-1955.I-Flash-Matic wasebenzisa aithoshi eliqondisayoukwenza kusebenze amaseli ezithombe esikrinini sikamabonakude, okuvumela abasebenzisi ukuthi bashintshe amashaneli futhi bathulise umsindo.Naphezu kobuchwepheshe bayo obudala, i-Flash-Matic yayinemikhawulo, kuhlanganise nokuphazanyiswa ukukhanya kwelanga neminye imithombo yokukhanya.
Ubuchwepheshe be-infrared kanye ne-Universal Remotes
Ngo-1956, uRobert Adler, omunyeUnjiniyela weZenith, yethule isilawuli kude se-"Space Command", esasebenzisa ubuchwepheshe be-ultrasonic.Irimothi ikhipha imisindo ephezulu, ethathwe umbhobho kumabonakude, ukuze ilawule ukusebenza kwayo.IUmyalo wesikhalayayinokwethenjelwa kakhulu kuneFlash-Matic, kodwa iimisindo yokuchofoza ezwakalayookukhiqiziwe kwathathwa njengohlupho kwabanye abasebenzisi.
Ubuchwepheshe be-infrared (IR) baqalwa ngeminyaka yawo-1980, bagcina buthathela indawo ama-remote ultrasonic.Lokhu kuthuthukiswa kuxazulule inkinga yomsindo wokuchofoza futhi kwathuthukisa ukwethembeka kukonke kwezilawuli kude.Izilawuli kude ze-infrareddlulisa isignali yokukhanya engabonakali kumamukeli kumabonakude, okuvumela abasebenzisi ukuthi balawule imisebenzi ehlukahlukene.
Ngalesi sikhathi, i-isilawuli kude sendawo yonkekwabuye kwathuthukiswa.Okokuqalaokukude kwendawo yonke, i-CL9 “CORE,” yasungulwa nguUSteve Wozniak, umsunguli weI-Apple Inc., ngo-1987. Lo mshini ungase uhlelwe ukuba ulawule izinto eziningi zikagesi, njengamathelevishini, ama-VCR, nezidlali ze-DVD, kusetshenziswa irimothi eyodwa.
Ukuphakamaye-Smart Remotes
Ngokufika kukamabonakude wedijithali nama-smart TV ekhulwini lama-21, izilawuli kude ziye zaba yinkimbinkimbi kakhulu.Amarimothi ahlakaniphile anamuhla ngokuvamile afaka inhlanganisela yezinkinobho ezivamile, izikrini zokuthinta, kanyeubuchwepheshe bokubona izwi, okuvumela abasebenzisi ukuthi balawule amathelevishini abo, kanye namasevisi okusakaza-bukhoma namanye amadivayisi axhunyiwe, kalula.
Amarimothi amaningi ahlakaniphile aphinde asebenzise ubuchwepheshe befrikhwensi yomsakazo (RF) ngaphezu kwamasignali e-infrared.Lokhu kuvumela abasebenzisi ukuthi balawule amadivayisi angekho kulayini wokubona oqondile, njengalawo afihlwe kumakhabethe noma ngemuva kwezindonga.Amanye amarimothi ahlakaniphile angalawulwa ngeizinhlelo zokusebenza ze-smartphone, ithuthukisa ngokuqhubekayo ukusebenza kwazo.
Ikusasaye-TV Remote Controls
Njengoba ubuchwepheshe buqhubeka nokuthuthuka, isilawuli kude se-TV kulindeleke ukuthi sithuthuke eduze kwakho.Ngokuthuthuka okuqhubekayo kwamakhaya ahlakaniphile kanye neI-inthanethi Yezinto(IoT), izilawuli kude zingase zihlanganiswe kakhudlwana ekuphileni kwethu kwansuku zonke, okusivumela ukuba singagcini nje ngokulawula amathelevishini ethu kodwa futhi nezibani zethu, ama-thermostat, nezinye izinto zasendlini.
Sengiphetha, isilawuli kude se-TV sesihambe ibanga elide kusukela ekuqaleni kwayo, sishintsha sisuka emshinini olula siye ethuluzini elithuthukisiwe elithuthukisa amandla ethu.isipiliyoni sokuzijabulisa sasekhaya.Kusukela ekuqaleni okuthobekile kwama-Lazy Bones kuya kumarimothi ahlakaniphile anamuhla, isilawuli kude se-TV silokhu sijwayelana nezidingo ezishintshayo zabasebenzisi, okuyenza ibe yingxenye ebalulekile yokuphila kwethu.
