we were planning to construct a device that functions as a tv receiver connected to the audio video ports of a crt tv set that connects to an external bluetooth device. the said device uses bluetooth for receiving. do i need to convert the received bluetooth signal to a tv signal? if so, how do i do this? i was just wondering if i could use my old crt tv as my cellphone screen or to connect it to my computer. hehehe... help me out and be easy with terms please.....
