The 20.3.1 Update thread
highlighted a mysterious new field showing up on the System Info Screen -- Collab Slice.
TiVo was issued a patent today (July 2, 2013) that seems to have solved this mystery. Collab Slice
refers to TiVo's proprietary distributed database system that provides a central database resident on servers that contains objects. These program objects are gathered together into a distribution package called "slices" and distributed by a range of techniques including private data channels in digital television signals.
