Hi and thanks to all Bros/Sis who replied to my thread.
First of all, the reason why i need to locate the schematic of a universal remote control was to understand in detail the circuitry on how the remote control works.The reason being I am currently trying to design some hardware which will automatically pause the hi-fi/dvd or mute the tv upon the arrival of an incoming call.I had already design the front part which consistutes of a phone detector circuit which will trigger the RF TX upon arrival of the telephone ringing, an RF RX will be placed in another room which the theather system is lcoated.Upon recieving the signal,"something needs to happen" to trigger the mute or pause.
Anybody can give me some idea how i could design the last part.My initial idea was to integrate a universal remote control to the RF RX but i do not know how i can do it.Please englighten.
Hey Yong
