<p>A querying device, such as a user interface (21), generates a query (202) for media content information from the Content Directory Service (CDS, 55) of a serving device (MS-a). A device providing a Query Estimation Service (QES, 70) also receives the query (203) and provides an estimate of at least one parameter of the response (204). This can include the expected time that the serving device (MS-a) will take to respond. The querying device provides feedback to the user corresponding to the delay, such as an appropriate form of graphical display.</p> |
