Abstract

Systems and methods according to the exemplary embodiments provide for chat session handling in IPTV systems. A chat server can be configured to forward text messages associated with a particular chat session toward an IPTV terminal for output thereon. Chat message entry can be performed by using a wireless text entry device, e.g., a mobile phone. An IPTV control server can be configured to recognize a request for a chat session which involves output of chat messages on an IPTV terminal, and to verify that the user has a linked mobile phone and IPTV subscriptions.
