Video wireless transmission

HI everyone,
I am trying to design a video (analog VGA video) wireless communication system for my UAV . I want to convert the analog video signal to digital and transmit it. But I cant find a suitable RF module and that can meet my spec.

Requirements:
Transmission data rate : >25Mbps or >4Mbps (if video compression is used)
Transmitting range : 5 -10km
Modulation : OFDM or other better option
Transmitting Freq. : 900Mhz or 2.4Ghz

Could u guys suggest any components that i can use. And how do i do the video compression (in firmware or hardware)?

Regards,
Alex
