摘要

The invention relates to a system for activating an IP television service (IPTV) in an IMS architecture network (2) from a terminal (10) of a user having subscribed to at least one television channel with said service. According to the invention, the system comprises, in the IMS architecture network (2), an IP television server (23) containing subscription information associating the user with the at least one channel, and information on the reception capacity required for the at least one channel, and the terminal (10) comprises means for transmitting a message towards the server (23), requesting activation of the television service and containing reception capacity information provided by the terminal (10). The server (23) can check the compatibility between the reception capacity information received from the terminal (10) and the reception capacity information required for the at least one channel, and if the compatibility is confirmed, can send a message in response to the activation request message, to the terminal (10), said response message containing an IP address of the at least one channel. The invention can be applied to IP networks enabling audiovisual data to be broadcast in the IMS.
