The present invention relates to a method for filtering and storing information about content, which is available on a network device in a network, wherein said network further comprises network rendering devices adapted for rendering content, the method comprising filtering the information by removing information about content, which cannot be rendered by at least one of said network devices adapted for rendering content, storing the filtered information and making it available on the network. When the network is a UPnP network, then control points have faster reaction times when they browsethe content directory service, the content directory being the stored filtered information. Further, less load on the content directory service, the control point and the network is obtained when thecontrol point browses the content directories. Further, the content presented to the user on the user screen of a control point only comprises content, which can be used.
