Abstract

A program time guide for an interactive viewing system allows a user to control the time and channels for which program information is displayed. The user can navigate through the program time guide to identify and select desired programs. The program time guide displays information for various types and sources of programming by assigning each program source a channel number. Selecting a program on a particular channel causes the system to tune to an associated frequency to receive video signals, launch a computer executed application which generates displayed information, or to perform some other activity associated with that channel or program.
