<h1> rpidatv Transmitter installation </h1>
```
sudo apt-get update && 
sudo apt-get install rpi-update && 
sudo rpi-update && 
sudo apt-get install apt-transport-https && 
sudo apt-get install git && 
git clone git://github.com/f5oeo/rpidatv && 
cd rpidatv/src && 
make -j 4
```

<h1> leandvb rtlsdr receiver installation </h1>
`./install.sh`   
This install leandvb : a simple dvb-s receiver with rtl-sdr usb dongle
([leandvb dvb-s receiver](http://www.pabr.org/radio/leandvb/leandvb.en.html))    
You can run the receiver : `./scripts/leandvb2video.sh`

<h1>Hardware</h1>
Plug a wire on GPIO 12, means Pin 32 of the GPIO header ([header P1](http://elinux.org/RPi_Low-level_peripherals#General_Purpose_Input.2FOutput_.28GPIO.29)): this act as the antenna. Length depend on transmit frequency, but with few centimeters it works for local testing.

<h1>Short manual</h1>
<h2> General </h2>
rpidatv is located in /bin folder
