This invention relates to a method of managing a media system (103, 201, 208) with a group identifier in a network (210) of media systems. The invention further relates to a media system for managing a network of media systems with a group identifier. The media system can be may be a set-top box, a TV, a PC, a DVD player, a radio, a screen, a camera or a VCR. Said method includes the steps of determining a status of the network, wherein the status represents the group identifier, presence and/or absence of at least one media system; and determining the group identifier for at least one media system based on the determined status. Said step of determining the group identifier comprises the alternative four steps of resetting the group identifier, when said media system is disconnected from the network; or giving an existing group identifier to a first media system (201), when said media system without a group identifier is connected to a second media system (202) having said existing group identifier; or keeping separate group identifiers to a third (203) and a fourth media system (204), when the third and the fourth media system are connected to the network; or giving a first group identifier specified by a user, when a fifth media system (205) is connected to the network to one or more media systems where none of these has a group identifier, and assigning the first group identifier to all of said media systems. Said method further includes the step of: giving a second group identifier specified by a user to a sixth media system (206). Hereby, it is made easy for a user to add, move and remove media systems without the user interaction, since the media systems themselves determine the group identifiers.
