LRP: Control data
HRP: Video & Audio data
Wireless TV is similar to the walkie-talkie. We must match the channel of Tx & Rx module.
There are 4 HRP channel(A1~A4). We use only A2 channel and 3 LRP channel like this [60.32㎓],
[60.48㎓],[60.64㎓].
First thing, the LRP channel setting has to be matched in wired mode. There are not only channel
but also mac address that Tx/Rx modules have it’s own for preventing wireless interference.
Set the LRP channel and share the mac address each other, that’s called pairing.
After pairing, Antenna search and set the wireless path by LRP and then send video & audio data to
HRP channel.
