Abstract
The invention relates to mobile devices (1) able to receive and reproduce information, for example as sound. The invention is particularly applicable to small mobile devices with no or inconvenient user interfaces. In order to update filter blocks to select message streams, filter blocks are transmitted from a separate transmitter, and recorded in memory (11). The filter blocks then control a filter (9) to replay messages from selected message streams on the output device or devices (19,21) of the mobile device (1).
