Abstract: An audio stream server (115) comprises a request processor (203) which receives an audiovisual stream request for an audiovisual stream from a communication unit (101). The request comprises a location indication for the audiovisual stream. A selection processor (205) selects a group of stream feed units (103) from a plurality of stream feed units in response to the location indication and a stream data processor (207) receives audiovisual streams from at least one stream feed unit of the group of stream feed units (103). A stream generation processor (209) then generates an audiovisual stream for the communication unit (101) from the received audiovisual stream and a stream transmit processor (211) transmits the generated audiovisual stream to the communication unit (101). The communication unit (101) and/or the stream feed units (103) may specifically be user equipments of a cellular communication system. The invention may allow an audio stream for a given real world location to be provided on request e.g.

Abstract: A method of generating a user profile initially comprises receiving (201, 203) characterising data, and optionally user preferences, for content items. The characterising data describes characteristics, such as content or context characteristics, of each content item. The content items are then clustered (205) into content item clusters in response to characterising data associated with each content item. For each content item cluster, cluster characterising data is determined (207) in response to characterising data and possibly user preferences associated with each content item in the content item cluster. First characterising data is then received (209) for a first content item and a first content item cluster is selected (211) in response to a comparison of the first characterising data and the cluster characterising data of each content item cluster. A user profile is then generated (211) for the first content item in response to first cluster characterising data of the first content item cluster.
