Lub chaw taws teeb tswj TV yog ib qho tseem ceeb ntawm cov khoom siv TVkev lom zem hauv tsev, uas tso cai rau cov neeg siv hloov cov channel yooj yim, kho qhov ntim, thiab mus saib cov ntawv qhia zaub mov. Tam sim no yog ib qho tseem ceeb hauv feem ntau tsev neeg, lub chaw taws teeb TV tau mus ntev heev txij li thaum nws pib xyoo 1950. Tsab xov xwm no yuav tshawb nrhiav txog keeb kwm ntawm lub chaw taws teeb TV, qhia txog nws cov kev txhim kho tseem ceeb thiab tshawb nrhiav nws cov kev hloov pauv mus rau hauv cov chaw taws teeb ntse niaj hnub no.
Cov Hnub Thaum Ntxov:TV tshuabCov chaw taws teeb tswj
Lub chaw taws teeb tswj TV thawj zaug, hu ua "Cov Pob Txha Tub nkeeg," tau qhia los ntawmZenith Xov Tooj Cua Corporationxyoo 1950. Lub cuab yeej no tau txuas rau lub TV los ntawm ib txoj hlua ntev, uas tso cai rau cov neeg siv hloov cov channel thiab kho qhov ntim ntawm qhov deb. Txawm li cas los xij, txoj hlua txuas tom qab yog qhov txaus ntshai rau kev ntog thiab tau ua pov thawj tias yog qhov kev daws teeb meem tsis yooj yim.
Yuav kom daws tau qhov teeb meem no,Qhov Zoo Tshaj Plawstus kws ua haujlwmEugene Polleyxyoo 1955, nws tau tsim lub "Flash-Matic," thawj lub chaw taws teeb tswj TV wireless.Lub Flash-Matic siv ib qhoteeb pom kevkom qhib cov photocells ntawm lub vijtsam TV, 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 cov kev txwv, suav nrog kev cuam tshuam los ntawm lub hnub ci thiab lwm yam teeb pom kev zoo.
Kev Siv Tshuab Infrared thiab Universal Remotes
Xyoo 1956, Robert Adler, lwm tusTus kws ua haujlwm Zenith, tau qhia txog kev tswj chaw taws teeb "Space Command", uas siv thev naus laus zis ultrasonic. Lub chaw taws teeb tso tawm cov suab nrov siab, uas tau khaws los ntawm lub microphone hauv lub TV, los tswj nws cov haujlwm.Kev Tswj Xyuas Chawtau txhim khu kev qha dua li Flash-Matic, tab sissuab nrov nrovnws tsim tawm tau suav hais tias yog kev thab plaub los ntawm qee tus neeg siv.
Cov thev naus laus zis infrared (IR) tau tsim tawm xyoo 1980, thiab thaum kawg tau hloov chaw tswj ultrasonic. Qhov kev nce qib no tau daws qhov teeb meem suab nrov thiab txhim kho kev ntseeg tau ntawm cov chaw tswj.Cov chaw taws teeb infraredxa ib lub teeb liab uas tsis pom mus rau lub receiver ntawm lub TV, cia cov neeg siv tswj tau ntau yam haujlwm.
Thaum lub sijhawm no,kev tswj chaw taws teeb thoob ntiaj tebkuj tau tsim tawm. Thawj zaugchaw taws teeb tswj thoob ntiaj teb, lub CL9 "CORE," tau tsim los ntawmSteve Wozniak, tus koom tsim ntawmKua Inc.., xyoo 1987. Lub cuab yeej no tuaj yeem raug tsim los tswj ntau yam khoom siv hluav taws xob, xws li cov TV, VCR, thiab DVD players, siv ib qho chaw taws teeb tswj.
Kev Sawv Rov Losntawm Cov Chaw Tswj Xyuas Ntse
Nrog rau kev tshwm sim ntawm cov TV digital thiab cov TV ntse hauv xyoo pua 21st, cov chaw taws teeb tswj tau dhau los ua qhov nyuaj dua. Cov chaw taws teeb tswj ntse niaj hnub no feem ntau muaj kev sib xyaw ua ke ntawm cov nyees khawm ib txwm muaj, kov tau, thiabkev siv tshuab paub lub suab, tso cai rau cov neeg siv tswj lawv cov TV, nrog rau cov kev pabcuam streaming thiab lwm yam khoom siv txuas nrog, tau yooj yim.
Ntau lub chaw taws teeb ntse kuj siv cov thev naus laus zis xov tooj cua zaus (RF) ntxiv rau cov teeb liab infrared. Qhov no ua rau cov neeg siv tswj tau cov khoom siv uas tsis nyob hauv kab pom ncaj qha, xws li cov uas zais rau hauv txee lossis tom qab phab ntsa. Qee lub chaw taws teeb ntse tuaj yeem tswj tau los ntawmcov apps ntawm xov tooj ntse, ntxiv txhim kho lawv cov kev ua haujlwm.
Yav Tom Ntejntawm TV Chaw Taws Teeb Tswj
Raws li thev naus laus zis txuas ntxiv mus, qhov chaw taws teeb tswj TV yuav hloov zuj zus nrog nws. Nrog rau kev txhim kho ntawm cov tsev ntse thiabInternet ntawm Tej Yam(IoT), cov chaw taws teeb tswj yuav koom ua ke ntau dua rau hauv peb lub neej txhua hnub, tso cai rau peb tswj tsis yog peb lub TV xwb tab sis kuj tswj peb lub teeb, thermostats, thiab lwm yam khoom siv hauv tsev.
Xaus lus, lub chaw taws teeb tswj TV tau mus ntev heev txij li thaum nws pib, hloov pauv los ntawm lub cuab yeej siv yooj yim mus rau lub cuab yeej siab heev uas txhim kho peb covkev lom zem hauv tsevTxij li thaum pib ntawm Lazy Bones mus rau cov chaw taws teeb ntse niaj hnub no, lub chaw taws teeb tswj TV tau hloov kho tas li rau cov kev xav tau ntawm cov neeg siv, ua rau nws yog ib feem tseem ceeb ntawm peb lub neej.
