Lub TV tej thaj chaw deb tswj yog ib qho tseem ceeb ntawm covkev lom zem hauv tsev, tso cai rau cov neeg siv siv zog hloov cov channel, kho qhov ntim, thiab taug kev los ntawm cov ntawv qhia zaub mov.Tam sim no ib qho tseem ceeb hauv tsev neeg feem ntau, TV tej thaj chaw deb tau los ntev txij li nws tau tsim nyob rau xyoo 1950.Tsab ntawv xov xwm no yuav piav qhia txog keeb kwm ntawm TV chaw taws teeb tswj, qhia txog nws qhov kev txhim kho tseem ceeb thiab tshawb nrhiav nws cov kev hloov pauv mus rau hauv cov chaw taws teeb ntse niaj hnub no.
Hnub Nyoog Kawg:Mechanical TVCov chaw taws teeb
Thawj TV chaw taws teeb tswj, dubbed lub "Tub nkeeg pob txha," tau qhia los ntawmZenith Radio Corporationxyoo 1950. Cov cuab yeej tau txuas nrog lub TV los ntawm lub cable ntev, tso cai rau cov neeg siv hloov cov channel thiab kho qhov ntim ntawm qhov deb.Txawm li cas los xij, txoj hlua txuas ntxiv yog qhov muaj kev phom sij txaus ntshai thiab ua pov thawj tias yog qhov tsis yooj yim.
Los daws qhov teeb meem no,ZenithengineerEugene Polleytsim lub "Flash-Matic," thawj wireless TV chaw taws teeb tswj, hauv 1955.Lub Flash-Matic siv acoj teeb nyemtxhawm rau qhib photocells ntawm lub TV lub vijtsam, tso cai rau cov neeg siv hloov cov channel thiab kaw lub suab.Txawm hais tias nws cov thev naus laus zis tshiab, Flash-Matic muaj kev txwv, suav nrog kev cuam tshuam los ntawm hnub ci thiab lwm qhov chaw teeb pom kev zoo.
Infrared Technology thiab Universal Chaw Taws Teeb
Xyoo 1956, Robert Adler, lwm tusZenith engineer, qhia txog "Space Command" chaw taws teeb tswj, uas siv tshuab ultrasonic.Cov chaw taws teeb tso tawm suab nrov, uas tau khaws los ntawm lub microphone hauv TV, los tswj nws txoj haujlwm.CovSpace CommandNws ntseeg tau ntau dua li Flash-Matic, tab sisaudible clicking suabnws tsim tau suav hais tias yog ib qho teeb meem los ntawm qee cov neeg siv.
Infrared (IR) thev naus laus zis tau nthuav tawm hauv xyoo 1980, thaum kawg hloov cov chaw taws teeb ultrasonic.Qhov kev nce qib no tau daws qhov teeb meem ntawm lub suab nrov thiab txhim kho tag nrho kev ntseeg siab ntawm cov chaw taws teeb tswj.Infrared chaw taws teebxa cov teeb liab pom tsis pom mus rau lub receiver ntawm lub TV, tso cai rau cov neeg siv los tswj ntau yam haujlwm.
Thaum lub sijhawm no, lubuniversal chaw taws teeb tswjkuj tau tsim.Thawjuniversal chaw taws teeb, CL9 "CORE," tau tsim los ntawmSteve Wozniak, co-founder ntawmApple Inc., xyoo 1987. Cov cuab yeej no tuaj yeem tsim los tswj ntau yam khoom siv hluav taws xob, xws li TV teeb, VCRs, thiab DVD players, siv ib qho chaw taws teeb.
Sawvntawm Smart Remotes
Nrog rau qhov tshwm sim ntawm digital TV thiab ntse TVs nyob rau hauv lub xyoo pua 21st, cov chaw taws teeb tswj tau dhau los ua neeg ntse dua.Niaj hnub no cov chaw taws teeb ntse feem ntau muaj kev sib xyaw ua ke ntawm cov nyees khawm, touchscreens, thiablub suab paub technology, tso cai rau cov neeg siv tswj lawv cov TV, nrog rau cov kev pabcuam streaming thiab lwm yam khoom siv txuas nrog, yooj yim.
Ntau lub chaw taws teeb ntse kuj tseem siv xov tooj cua zaus (RF) thev naus laus zis ntxiv rau cov teeb liab infrared.Qhov no ua rau cov neeg siv los tswj cov khoom siv uas tsis nyob hauv txoj kab ncaj nraim ntawm qhov pom, xws li cov khoom zais hauv cov txee lossis tom qab phab ntsa.Qee cov chaw taws teeb ntse tseem tuaj yeem tswj tau ntawmsmartphone apps, ntxiv txhim kho lawv functionality.
Lub neej yav tom ntejntawm TV tej thaj chaw deb tswj
Raws li kev siv thev naus laus zis txuas ntxiv mus, TV chaw taws teeb tswj yuav tsum tau hloov zuj zus mus nrog nws.Nrog kev txhim kho txuas ntxiv ntawm cov tsev ntse thiab covInternet ntawm Yam(IoT), cov chaw taws teeb tswj yuav dhau los ua kev sib koom ua ke hauv peb lub neej niaj hnub, tso cai rau peb tswj tsis tau peb lub TV nkaus xwb tab sis kuj peb lub teeb, ntsuas kub, thiab lwm yam khoom siv hauv tsev.
Hauv kev xaus, TV cov chaw taws teeb tswj tau los ntev txij li nws pib, hloov los ntawm cov cuab yeej siv tshuab yooj yim mus rau cov cuab yeej siv siab heev uas txhim kho peb cov khoom.kev lom zem hauv tsev.Los ntawm qhov pib txo qis ntawm Lazy Bones mus rau qhov ntse ntse chaw taws teeb niaj hnub no, TV chaw taws teeb tswj tau txuas ntxiv hloov mus rau cov kev xav tau ntawm cov neeg siv hloov pauv, ua rau nws yog ib feem tseem ceeb ntawm peb lub neej.
