Abstract: Bandwidth use between an access provider system (14) and a user computer (10) is adapted to an amount of subscription quotum that has been used by a subscriber. Quotum use information is representative of an amount of data that has been exchanged between the user computer (10) and an access provider system (14) since a predetermined time point. A request is received for retrieving media information from the network (16) and for rendering that media information at the user computer (10). In response to the request a selection is made between a plurality of versions of the requested media information, dependent on the quotum use information. Different versions require respective different data rates for transmission from the access provider system (14) to the user computer (10). The more quotum has been used, the lower the data rate of the selected version.
