Sirius satellites radio's David Frear spoke at the Bernstein Conference today, and covered SIRIUS video and bandwidth:
Video and additional bandwidth are basically tied at the hip. Sirius has developed a hierarchical modulation, which they now refer to as (thankfully) "Overlay Modulation". Overlay Modulation allows Sirius to in effect increase the use of their current bandwidth by 25%.
It is this additional capacity that will allow Sirius to offer three live video channels. They will also have some capacity to spare, enabling them to tweak other content as opportunity arises.
Frear indicated that these services may be available as early as the end of the year.
