Saw this on Slashdot:
High Definition TV has been successfully captured in its native data stream from an over the air broadcast by a software defined radio that is Free and open source from the GNU Software Defined Radio project.
This is a terrific development. As you may already know GNU Radio is a general purpose radio that is entirely open source. So not only can this device act like any other wireless device, it is not proprietary either. This means that you can capture HDTV signals with an open-source device which is not beholden to special interests and their broadcast flag which will otherwise be rammed down our throats by 2007. This is a classic example of information wanting to be free.
