Sunday, July 14, 2002: 2:00 pm (Area "B"): The GNU Radio project is building a platform for experimenting with software radios - systems where the actual waveforms received and transmitted are defined by software, not special purpose hardware. One of their projects is building an all-software ATSC (HDTV) receiver. An all-software free ATSC receiver would allow among other things the construction of the mother of all "personal video recorders." Think Tivo or Replay on steroids. The folks from the Broadcast Protection Discussion Group (BPDG) have other ideas. They'd like to lock up the cleartext signal and make sure that only members of their club would be allowed to build receivers, modulators, and storage devices for digital TV. A discussion of where this is all likely to head. Panel participants include GNU Radio technical representative Eric Blossom and Lodrina Cherne from the EFF.
