Usakhumbula ezo ntsuku zozuko kwihlabathi leNokia, kwaye yabizwa ngokuba yinkosi yefowuni ye-N95? Kwi-1995, kwakukho ii-portals ezininzi kwixesha le-2G kunye nesofthiwe yentlalontle yavela. Kwi-2000, kwixesha le-3G yeefowuni ezihlakaniphile, isofthiwe yentlalontle yaba ngukumkani. Kwi-2013, ngexesha le-4G, ukusasazwa okubukhoma kunye neevidiyo ezimfutshane zazidume ngokulinganayo, kwaye ukuhamba kolwazi kwaba yinto eshushu. Ukujonga ngasemva hayi kude izolo, ubomi bedijithali buzolile beza kuthi, kunye neefowuni eziphathwayo, iTV nayo iphucula. Iseti kamabonakude eyayikhe yamnyama namhlophe endaweni yayo kwafakwa umabonakude we LCD ngombala, nto leyo esivumela ukuba sibukele ihlabathi ekhaya. Phakathi kwabo, iteknoloji kunye nesantya sophuhliso lweTV yodwa inesibheno esikhulu, kodwa namhlanje ndifuna ukuthetha malunga neteknoloji yeTV, kodwa ulawulo olukude oluhamba nalo.
Uphuhliso lolawulo olukude lunokulandelwa emva phaya kwiminyaka yoo-1950.
Ngomnyaka we-1950, umphathi omkhulu wezobuchwephesha uJohn McDonald wacela umngeni kwiinjineli zakhe ukuba zize nesixhobo esinokuvala izibhengezo zentengiso okanye sizithumele kwelinye ijelo.
Ulawulo olukude lwazalwa.
Ekuqaleni, inokutsalelwa kuphela kwiTV yakho. Kwiminyaka emihlanu kamva, u-Eugene Polley, injineli kwinkampani enye, waphuhlisa isixhobo sokuqala esingenazingcingo esilawulwa ngokukhanya esibizwa ngokuba yi-flashmatic, esamenza ukuba abe ngutata wolawulo olukude lwethelevishini.
Kodwa izixhobo, ezinokutshintsha izitishi kunye nokulungelelanisa umthamo, azisetyenziswanga ngokubanzi kuba kunzima ukuzilawula.

Emva koko, ngo-1956, uRob Adler waphuhlisa iZenith Space Command elawulwa kude. Isebenzisa umgaqo we-ultrasound ukulungelelanisa umthamo kunye nejelo. Isitshixo ngasinye sikhupha i-frequency eyahlukileyo, kodwa isixhobo sixhomekeke kukuphazamiseka okuqhelekileyo kwe-ultrasonic.
Ukuza kuthi ga ngo-1980, i-remote control ye-infrared yazalwa, kwaye ngokuthe ngcembe yathatha indawo yesixhobo sokulawula i-ultrasonic. Ulawulo olukude lwe-infrared kukusetyenziswa kokukhanya kwe-infrared ukuhambisa imiyalelo, oko kukuthi, singawona maqhosha amade aqhelekileyo olawulo olude.
Uphuhliso lolawulo olukude ukuza kuthi ga ngoku, abavelisi abaninzi bolawulo olukude baqalise imisebenzi eyahlukeneyo, kubandakanya nolawulo lwelizwi, okwaziwa ngokuba yiBluetooth yolawulo olukude, kufuneka nje ucofe isitshixo selizwi solawulo olukude ukuthetha nomabonwakude, ukuqondwa kweTV kuya kwenziwa. ngaxeshanye. Kodwa ngokuqinisekileyo loo nto ayizange ilufezekise usukelo lwezandla de ezinye iibhrendi zaqala ukunika amandla okusebenzisana nelizwi elikude elikuvumela ukuba ulawule iTV yakho ngelizwi lokuvuka ngaphandle kokufumana ukude.
