A data feed is monitored to determine whether a condition is satisfied. If
the condition is satisfied, an alert is initiated to attract a user's
attention. Thereafter, playback mode is entered causing the example
system to playback a short period of time-compressed data that occurred
just prior to the event occurring to set context for the user. Once the
playback signal has caught up with the real-time data feed, the data is
output at normal levels. Other configurations, which are described
herein, are also possible.
