You prefer it .
Yeah. Uh as you know , I am mister Ramaro. I am an expert in uh industrial design of all electronic devices and I previously devised many uh  like digital calculators and electronic calculators.  So now I'll briefly describe the working design of our remote control. Well , as you know the basic function of remote control is sending some message to the the device , like T_V_ or V_C_R_ or D_V_D_ player etcetera. So we will have a p portable device which will send message to the the main device like T_V_. So we need to have some energy source to do what  to do the functions , what we want on this portable device.  And usually this  so to do these functions we need an interface , which basically some kind of pressing buttons or keys or like moving jack or something like that. And then these messages  these key buttons can be transferred into some kind of message and then it will process by the chip and then it will generate some information to the main device. It's generally in the form of infrared or some kind of s sensor information. Then we will have the main control in the main device to do the particular action what we want. So , basically we need uh since we are focusing on our interface device  remote control mainly the energy source like the battery and then we have user interface like uh the keypad and you know buttons we want , and then we have some chip , it's mainly digital signal processing chip because since we are  I am one doing mostly digital uh devices we ought to have some kind of processor which take care of all these functions and put it in some digital format. And then we'll have the infrared L_E_D_ source which sends the information to the main device. Then we'll have switch in our main uh um device to do particular operations , and we ought to do different codes for different T_V_s ,
Mm-hmm.
so some T_V_s will have different encryption codes for doing s s uh channel changing and these things.
