METHOD FOR SENSING USER PRESENCE FOR BUDDY LIST APPLICATIONS

摘要

A method and system for sensing and reporting various types of user presence using "buddy list" applications. A buddy list client senses various types of user presence of a user and sends status information corresponding to the sensed user presence to a server. The buddy list client also receives status information from the server corresponding to various types of user presence information of buddies, and displays a buddy list indicating the various types of user presence information of the buddies. This can be implemented on an IPTV client in order to sense and display presence information relating to a user watching television.
