Gnuradio / USRP for Demodulating Multiple NTSC Streams

GNU Radio
1

Hello,

I would like to demodulate multiple NTSC video streams in real time from
2,000 to 2,100 Mhz. Video signals (haven’t located audio yet but could
do without it) are centered around 12 Mhz apart. Ideally, this would be
8 or so simultaneous streams. I would settle for a single stream with a
straightforward way of selecting another frequency. This is for a
mobile application.

I have looked at:

  1. Dedicated RF to Video demodulation hardware. For 2.4Ghz this is
    readily available and dirt cheap but I have only been able to find one
    device in the frequency range I am interested in. That device for
    2-2.1Ghz lists for over $1,000 CDN.

  2. Use of wide band receivers as front ends to gnuradio. This appears
    to require IF output and even if I do find a portable radio that has IF
    it is not clear that to me if that solution will work even for one
    stream.

  3. Use of USRP and gnuradio. This seems to be the best option so far.
    Current USRP is USB based which will work with my laptop. USRP2 would
    require purchase of mobile device with gigabit interface.

Is there something else I should look at? Can dedicated 2.4Ghz
demodulation hardware be converted to 2-2.1Ghz? Is USRP or USRP2 my
best option?

Thanks,

John
