transmitter wireless digital video

HI
I want to ask about some circuits which used in designing wireless digital video transmitter
or sites which can help us in design.

In general such design must consist of two major part. First one is some king of MPEG encoder, and the second modulator with HF PA. Each of them is quite complicated.

and I think most important is the frenquency response of your transmitter,if you use FM to transmit the video.because the video has about 8MHz bandwidth.

I am interested too in short range (metres) wireless video. Any info on this argument?

thx a lot!
