文章讨论了用Wi-Fi转TTL电路替代电视机红外接收电路,在智能手机中增加Wi-Fi控制电视机的应用程序,使电视机具有被智能手机Wi-Fi控制的功能。文中给出了Wi-Fi转TTL的电路,智能手机应用程序设计方法和程序框图。本文还讨论了智能手机通过Wi-Fi对家中多台电视机遥控的方法,以及如何应对空中一般性的电磁干扰,为减少家庭中红外遥控器的种类和数量提供了一种方法。
The article discusses the use of Wi-Fi to TTL circuits instead of TV infrared receiving circuits, adding Wi-Fi to smart phones and controlling TV applications that make TVs feature Wi-Fi controlled by smartphones. The article gives the Wi-Fi to TTL circuit, smart phone application design methods and block diagrams. This article also discusses ways in which smartphones can remotely control multiple TVs in their home via Wi-Fi and how to cope with the general electromagnetic interference in the air, providing a way to reduce the number and type of infrared remote controllers in the home.
