Abstract: In order to provide a content managing module (100, 102) as well as a method for controlling interactive applications, wherein a first data stream (D1) comprising at least one first interactive application with first interactive content is received, the first data stream (D1) being transmitted on at least one first channel, wherein it is possible to prevent a lack of interactive content stream when a consumer or user changes channel (and somewhat later changes back) while watching interactive content, it is proposed to keep receiving the first interactive content when switching (s) from the first channel to at least one second channel on which a second data stream (D2), in particular comprising at least one second interactive application with second interactive content, is transmitted.

Abstract: This invention relates to a method and a system for evaluating proximity. A reference object is moved such that it enters at least two different proximity areas of two different proximity indicators, whereby proximity indications are generated. The time difference between the indications is measured. If the time difference is within predefined range it is ascertained that the reference object is within a well defined area. Thus, the fact that the speed of movement of a physical object is significantly limited is used for obtaining reliable proximity evaluations.

Abstract: In Authorized Domains the management of which devices that can access content is a key issue. The Authorized Domain must be limited to a relatively small group of devices to get a solution that is acceptable to both content providers and users. However, current solutions are typically either to rigid to be future proof and user friendly or not effective enough in limiting the size of the Authorized Domain. This invention provides a user-friendly, flexible and yet effective method of managing the size of an Authorized Domain. The method proposes to group devices in the Authorized Domain into clusters, if a predetermined requirement is met, and to limit the number of clusters. Such a predetermined requirement could be a proximity requirement.
