I creating video sender (transmitter) and receiver.
The rf section working good. Working up to 10km.
video signal (camera) -> ad -> coder (compresser) -> digital radio tx digital radio rx -> decoder/error correction -> da -> analog video signal
What the prefered video coder/decoder, ad/da pair for composite video signal?
Aspect: total transmitting delay no longer that 200ms.
If the signal lost any time, then decoder detect it, and freeze prev frame.
I use PAL video camera width 25-30fps.
My radio is working up to 128/256kbit/s. Max real data rate is 90-180kbit/s.
This design make for RC airplane. Airplane use an camera. Remote station is controlling the airplane.
