• comparing the information acquired with the capability of the mobile terminal to determine whether or not conversion of the content is necessary;
• and
• converting, in case it is determined that the conversion is necessary, one or more of the codec, bit rate, resolution and file format of the content to generate content adapted to the capability of the mobile terminal and transmitting the so generated content to the mobile terminal over the radio network.
