There are actually three levels of functionality which could usefully be
distinguished:
(1) The automatically scrolling program guide provided on a dedicated channel in
most cable systems. The viewer has no control over the information display
whatsoever. It just scrolls slowly along.
(2) The interactive program guides provided on many first generation cable boxes.
The viewer can call up a grid display at will, and can scroll forward and backward
through both channels and time slots. The viewer can also call up textual
descriptions of programs in the grid and can tune directly to a program in the grid
with a single remote control click if it is in the current time slot.
(3) The more sophisticated program guides available on the Internet and on some
satellite and cable systems, which provide search and filtering facilities of the
sort described in Martin Spamer's message.
