<p>A time-shift buffer of recorded programming whose time of recording extends between a predetermined lower limit up to the present time is navigated by the user by means of a displayed clock face in selecting a desired program for immediate or deferred playback. Rewinding of hands on the clock face, under user control, causes the minute hand to enter a sector of the clock face representative of a time interval during which incoming programming was recorded. An identifier of the program is displayed in concert with the clock hand positioning, so that the user may at any point in the navigation select the currently-identified program for playback.</p> |
