Help with Design of Wireless Transceiver of S Video + Audio

Hello Everyone,

I am in Canada and currently I have this project to complete.
I want to transmit the s video + the audio L and R. The other end should receive back the s video + the audio L and R.

I know the S video has mainly the critical Y and C signal. In total, I would have to transmit 4 unique signals. As such I was thinking of OFDM to allow the broadcast of multiple signals.

As such, I guess
I would convert all 4 signals into 4 digital output,
send it into a IFFT block,
parallel to serial
guard interval insertion

transmit the OFDM signal
receive the OFDM signal

guard interval removal
serial to parallel
FFT the data
then digital back to analog


I just like to get exactly/most of the data back (that's why i'm using OFDM currently). This device would ideally be used for transmitting from tv to pc (with tv tuner card). I know I should not even try to design everything from scratch. I need to process everything like real time + fast.

I do not know the baud rate for s video. Can you guys recommend any modules/pieces I should get to satisfy my requirements?

I can spend at least 500 - 1000
