Method implemented by a communication device (121; 122) of a communication system, said communication device being connected via a communication network to other communication devices (131; 141) of said communication system, characterized in that, on detection of a change in availability of at least one of its hardware resources, the change in availability being linked to the connection of the communication device to the communication network and/or to a change in use of the hardware resources and/or connection/disconnection of a cable, the communication device carries out an advertisement phase comprising the following steps: - obtaining a list of possible local services corresponding to actions which said communication device is able to implement using its hardware resources, the possible local services being services comprising at least one of the following functions: - processing audio and/or video content, - making audio and/or video content available for display, - storing audio and/or video content, - configuring said communication device, - updating firmware of said communication device, - accessing online games, - accessing websites; - obtaining a list of hardware resources of said communication device which are necessary for offering said local services, the hardware resources being at least one tuner and/or at least one data storage space and/or at least one communication interface and/or an integrated webcam and/or at least one component dedicated to a particular processing operation; - obtaining a list of available local services among the possible local services, based on the hardware resources which are necessary for offering said local services and based on the actual availability of its hardware resources, the communication device taking into account a schedule of reservations of local services of said communication device, so that, when the schedule shows that hardware resources should be occupied for a period of time which starts in a time less than a predefined threshold, said communication device considers that said hardware resources are not available; and - advertising, via the communication network, the obtained list of available local services, in order to allow at least one manager device to display generally available services within the communication system with the aid of lists of available local services advertised by the communication devices of said communication system. - obtaining a list of possible local services corresponding to actions which said communication device is able to implement using its hardware resources, the possible local services being services comprising at least one of the following functions: - processing audio and/or video content, - making audio and/or video content available for display, - storing audio and/or video content, - configuring said communication device, - updating firmware of said communication device, - accessing online games, - accessing websites; - obtaining a list of hardware resources of said communication device which are necessary for offering said local services, the hardware resources being at least one tuner and/or at least one data storage space and/or at least one communication interface and/or an integrated webcam and/or at least one component dedicated to a particular processing operation; - obtaining a list of available local services among the possible local services, based on the hardware resources which are necessary for offering said local services and based on the actual availability of its hardware resources, the communication device taking into account a schedule of reservations of local services of said communication device, so that, when the schedule shows that hardware resources should be occupied for a period of time which starts in a time less than a predefined threshold, said communication device considers that said hardware resources are not available; and - advertising, via the communication network, the obtained list of available local services, in order to allow at least one manager device to display generally available services within the communication system with the aid of lists of available local services advertised by the communication devices of said communication system.
