Tseem nco ntsoov tias hnub muaj koob meej nyob hauv ntiaj teb ntawm Nokia, thiab tau raug hu ua huab tais ntawm N95 xov tooj txawb?Xyoo 1995, muaj ntau lub portals hauv 2G era thiab social software tau tshwm sim.Xyoo 2000, hauv 3G era ntawm cov xov tooj ntse, social software tau los ua vaj ntxwv.Nyob rau hauv 2013, nyob rau hauv lub era ntawm 4G, nyob streaming thiab luv luv yeeb yaj duab tau sib npaug zos, thiab cov ntaub ntawv txaus los ua ib tug kub lub ntsiab lus.Saib rov qab tsis deb nag hmo, lub neej digital ntsiag to tuaj rau peb, thiab cov xov tooj ntawm tes, TV kuj tau kho dua tshiab.Ib zaug monotonous dub thiab dawb TV teeb tau raug hloov los ntawm cov xim LCD TV, tso cai rau peb saib lub ntiaj teb hauv tsev.Ntawm lawv, thev naus laus zis thiab kev nrawm ntawm kev txhim kho ntawm TV ib leeg muaj qhov kev thov zoo, tab sis hnub no kuv xav tham txog tsis yog TV thev naus laus zis, tab sis cov chaw taws teeb tswj uas mus nrog nws.
Kev txhim kho ntawm cov chaw taws teeb tswj tuaj yeem taug qab rov qab mus rau xyoo 1950s.
Xyoo 1950, zenith electronics ceo John McDonald tau tawm tsam nws cov engineers kom tuaj nrog ib lub cuab yeej uas tuaj yeem kaw cov kev tshaj tawm lossis xa lawv mus rau lwm qhov.
Cov chaw taws teeb tswj tau yug los.
Thaum xub thawj, nws tsuas yog xaim rau koj lub TV.Tsib xyoos tom qab, Eugene Polley, ib tug engineer ntawm tib lub tuam txhab, tsim thawj lub teeb-beam tswj wireless ntaus ntawv hu ua flashmatic, uas tau txais nws lub npe ntawm leej txiv ntawm lub TV chaw taws teeb tswj.
Tab sis cov khoom siv, uas tuaj yeem hloov cov channel thiab kho qhov ntim, tsis tau siv dav vim tias lawv nyuaj rau tswj.

Tom qab ntawd, xyoo 1956, Rob Adler tau tsim Zenith Space Command chaw taws teeb tswj.Nws siv lub hauv paus ntsiab lus ntawm ultrasound los kho cov ntim thiab channel.Txhua tus yuam sij emits ntau zaus, tab sis cov cuab yeej raug cuam tshuam los ntawm ultrasonic.
Txog xyoo 1980, cov chaw taws teeb tswj infrared tau yug los, thiab nws maj mam hloov lub tshuab tswj ultrasonic.Infrared chaw taws teeb tswj yog kev siv lub teeb infrared los xa cov lus qhia, uas yog, peb yog cov nyees khawm ntev tshaj plaws ntawm cov chaw taws teeb tswj.
Kev txhim kho kev tswj chaw taws teeb kom deb li deb, ntau lub tuam txhab ntawm cov chaw taws teeb tswj tau pib ua haujlwm sib txawv, suav nrog lub suab tswj, tseem hu ua Bluetooth lub suab tswj chaw taws teeb, tsuas yog xav tau nias lub suab yuam sij ntawm cov chaw taws teeb tswj los tham nrog TV, kev lees paub TV yuav ua haujlwm. tib lub sijhawm.Tab sis qhov ntawd yeej tsis ua tiav lub hom phiaj ntawm tes dawb kom txog rau thaum qee lub npe pib muab lub suab sib tham nyob deb uas tso cai rau koj tswj koj lub TV nrog cov lus tsa suab yam tsis tas yuav nrhiav chaw taws teeb.
