Even when digital media of the respective devices are not media of common codec, the digital media can be reproduced in other device. A digital medium is provided to a providing destination device which reproduces the digital medium upon receiving it. Before providing the digital medium, a codec which can be used in the providing destination device is reported to the providing source device (step 22 ). The provision of the digital medium is directly performed without performing conversion if the codec is a predetermined common codec. If the codec is not the common codec, it is converted into a medium format of the common codec. Alternatively, if the codec can be used by the providing destination device, the codec is directly used in the medium format (steps 23 - 26 ).
