<p>Based on local detection of input events (fig.2 250) at a subscriber unit (fig.1 102,103), presentation of subscriber-targeted information (e.g., audio or visual data) may be quickly halted in response to a barge-in request indicated by an input event. The determination whether a given input event constitutes a valid barge-in request is preferably based on input event prioritization data provided to the subscriber from, for example, a server running one or more applications currently communicating with the subscriber unit. Furthermore, detection of an input event indicative of a barge-in request at a subscriber unit causes the subscriber unit to transmit a message to the source of the subscriber-targeted information (e.g., the server) (fig.3 340), which message in turn causes the information source to discontinue presentation of the subscriber-targeted information. In this manner, the present invention provides a technique for quickly responding to barge-in requests regardless of the delay characteristics of the underlying communication system.</p> |
