Providing a real world audiovisual stream to a communication unit

An audio stream server 115 comprises a request processor (203 fig.2), which receives a request for an audiovisual stream from a communication unit 101. The request includes a location indication for the audiovisual stream. A selection processor (205 fig.2) 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 fig.2) receives audiovisual streams from at least one stream feed unit of the group of stream feed units 103. A stream generation processor (209 fig.2) then generates an audiovisual stream for the communication unit 101 from the received audiovisual stream and a stream transmit processor (211 fig.2) transmits the generated audiovisual stream to the communication unit 101. The communication unit 101 and/or the stream feed units 103 may 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. using an existing cellular communication system.
