Abstract
A pervasive information retrieval system is disclosed in consumer electronics and home entertainment for retrieval of audio and visual information but also information containing text, pictures etc. in a multi user and multi domain environment comprising a plurality of physically distributed sub-domains having different rendering units, such as loudspeakers, television screens etc. The user is enabled to “grab” an ongoing information rendering experience, such as listening to a piece of music or to a broadcasted radio channel, watching a film or a broadcasted television programme, move to another sub-domain and “throw” the experience onto that sub-domain, where the experience will continue without the need to further operate the rendering units in the selected sub-domain.

1-30. (canceled)
Information retrieval system (AVRS) comprising
- at least one data communication network (DCN) communicating with at least two sub-domains (SUB A, SUB B, . . . SUB m), being physically distributed spaces,
- a plurality of units of information (UOI) accessible via said data communication network (DCN),
- each sub-domain comprising one or more rendering units (ARU, VRU) for outputting said units of information (UOI) to a user,
- at least one user activated unit (UAU1, UAU2, UAU3, . . . , UAUn) by means of which a user defined pointer (UDP) relating to a sub-domain may be established by a user (“grab”),
- at least one sub-domain selector for establishment under control by said user of an association between at least one selected sub-domain (SUB A, SUB B, . . . SUB M) and said user defined pointer (UDP) for subsequent rendering in said selected sub-domain (“throw”) of the units of information (UOI) being rendered in the sub-domain related to the user defined pointer (UDP) at the time of the establishment of said user defined pointer (UDP) and access control means for controlling the access of at least two users to the system,
- the access control means being adapted to receive unique identification data from a user and based thereon selectively allow the user to have access to at least parts of the system
- wherein the access control means may selectively allow the rending of units of information (UOI) in a specific sub-domain,
- the access control means further comprising, for at least some of the sub-domains of the system, a defined hierarchy of users, the access control system being adapted to allow said rendering only in case said sub-domain is not in use for rendering units of information (UOI) by another user having a superior hierarchy position.
Information retrieval system (AVRS) comprising
- at least one data communication network (DCN) communicating with at least two sub-domains (SUB A, SUB B, . . . SUB m), being physically distributed spaces,
- a plurality of units of information (UOI) accessible via said data communication network (DCN),
- each sub-domain comprising one or more rendering units (ARU, VRU) for outputting said units of information (UOI) to a user,
- wherein at least one of the sub-domains further comprises means for presenting one or more selectable content suggestions to a user, each content suggestion representing at least one of said units of information (UOI), the system further comprising content suggestion control means for generating said one or more content suggestions to each separate user from stored data relating to each user of the system, the content suggestion control means comprises means for collecting and storing user behaviour data relating to rendering of units of information (UOI) within the system, said user behaviour data including associated information identifying at least the user, the unit of information (UOI) and the sub-domain of the system at which the units of information (UOI) was rendered, and the content suggestion control means further comprises means for evaluating said stored user behaviour data and provide content suggestions based on said evaluation.
