摘要： A receiver (Figure 2), receives IP session announcement signals from a terrestrial digital video broadcasting system. Each IP session announcement (RM) includes information concerning announcements on an immediately lower level as well as information identifying the quantity of announcement data, such as the number of announcement messages, and a timeout value. The quantity data tells the receiver how many messages XI to X3 it needs to receive (C) before it has received all the relevant announcement messages. The timeout value informs the receiver how long it can wait before again receiving the messages X1 to X3 (which may have changed in content by then). After initially receiving the messages X1 to X3, the receiver may sleep (E), or it may receive announcement messages from another channel Y (D).

摘要： Improved systems and methods for establishing peer-to-peer calls such as voice over IP calls and video over IP calls. In various embodiments of the invention, SMTP messages are exchanged between devices using a SMTP server, with the SMTP messages including IP address information. With this arrangement, the need for SIP service providers can be eliminated. In other embodiments of the present invention, SMS messages including IP address information are transmitted between devices during a GSM or other type of telephone call, enabling the call to 'migrate' to a VoIP or video over IP call.

摘要： The invention relates to signalling in broadcast and multicast environments. For a service in the broadcast is defined an indicator, which is formulated into a unique indicator. The indicator is mapped into one time-slot in a signalling channel. A notification relating to the service is transmitted during the said time-slot. The notification is used for enabling the receiver for receiving said service, wherein the receiver may be turned off at other times.
