Kontroolka fog waa aaladda gudbinta bilaa-waayirka ah ee adeegsata tignoolajiyada casriga ah ee codaynta dijitaalka ah si ay u codeeyaan macluumaadka badhanka, oo ku sii daaya hirarka iftiinka iyada oo loo marayo diode infrared ah.Mowjadaha iftiinka waxaa loo beddelaa calaamadaha korantada ee qaataha infrared-ka ee soo-dhowrka, oo uu dejiyo processor-ku si uu u jajabiyo tilmaamaha u dhigma si loo gaaro shuruudaha hawlgalka ee loo baahan yahay ee lagu xakameynayo qalabka sida sanduuqyada set-top.
Lama hubo cidda ikhtiraacay kontoroolka fog ee ugu horreeya, laakiin mid ka mid ah kontaroolada fog ee ugu horreeya waxaa sameeyay hal-abuure lagu magacaabo Nikola Tesla (1856-1943) oo u shaqeynayay Edison oo sidoo kale loo yaqaanay hal-abuure xariif ah 1898 (US Patent No. 613809) ), oo loo yaqaan "Habka iyo Qalabka lagu Xakamaynayo Mechanism of Baabuur ama Baabuurta".
Kantaroolka fog ee ugu horreeya ee loo isticmaalo in lagu xakameeyo telefishinku wuxuu ahaa shirkad koronto oo Mareykan ah oo la yiraahdo Zenith (hadda ay heshay LG), taasoo la allifay 1950-meeyadii oo markii hore la xiray.Sanadkii 1955-tii, shirkaddu waxay soo saartay qalab wireless-ka laga hago oo la yiraahdo "Flashmatic", laakiin qalabkani ma kala saari karo in iftiinka iftiinka uu ka soo baxayo kontoroolka, sidoo kale wuxuu u baahan yahay in la is waafajiyo si loo xakameeyo.Sannadkii 1956kii, Robert Adler waxa uu soo saaray kontarool fog oo loo yaqaan "Zenith Space Command", kaas oo sidoo kale ahaa qalabkii ugu horreeyay ee casriga ah ee kantaroolka fog ee wireless-ka.Waxa uu isticmaalay ultrasound si uu u hagaajiyo kanaalka iyo mugga, badhan kastana waxa uu soo daayay soo noqnoqosho kala duwan.Si kastaba ha ahaatee, qalabkani waxa kale oo laga yaabaa in uu dhibsado ultrasoundka caadiga ah, dadka iyo xayawaanka qaarkood (sida eeyaha) ayaa maqli kara codka ka soo baxaya kontoroolka fog.
Sanadihii 1980-meeyadii, markii aaladaha semiconductor ee dirida iyo helitaanka fallaadhaha infrared la sameeyay, waxay si tartiib tartiib ah u beddeleen aaladaha xakamaynta ultrasonic.In kasta oo hababka kale ee gudbinta bilaa-waayirka ah sida Bluetooth-ka ay sii wadaan in la horumariyo, tignoolajiyadan ayaa ilaa hadda si weyn loo isticmaalo.
