Abstract: The present invention relates to a conferencing architecture, and also to a logic control module and a conferencing module. The conferencing architecture, logic control module and conferencing module grant some of a group of terminal users communication rights to communicate together. The conferencing architecture includes both the logic control module and the conferencing module. The logic control module is in communication with the group of terminal users, and maintains a list of at least one predetermined criterion and associated communication rights. The logic control module monitors status of the terminal users and, upon a change of status of at least one of the terminal users, if the change of status corresponds to at least one of the predetermined criterion, generates a message for modifying the communication rights accordingly. The conferencing module receives the message and changes the communication rights amongst the terminal users in accordance with the message.

Abstract: A method, system, and service provider for program-on-demand service in a telecommunications network, wherein a Session Initiation Protocol (SIP) terminal sends to a service provider, preferably over an HTTP link, a program request for a plurality of selected programs. The service provider determines which content provider stores the first program, and establishes an SIP session between that content provider and the SIP terminal, session which is used for streaming the first selected program to the SIP terminal, preferably using Real-Time Protocol (RTP). At the termination of a first program, the service provider releases the first SIP session and establishes a second SIP session between the SIP terminal and a second content provider storing the second program. The service provider may have a Web Server for selecting programs, and may be connected to an SIP functionality having a Parlay/SIP converter and an SIP server for handling SIP sessions using Parlay/OSA-based messages.
