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.
