A wireless receiver, in the form of a mobile telephone, includes a DAB receiver and a GSM/GPRS transceiver which enables bi-directional point-to-point data communications via a service provider. The DAB receiver is arranged to receive media data from an over-the-air broadcast channel, the media data primarily representing television and radio streams. In order that the streams can be decoded and decrypted by media playing software on the wireless receiver, a provisioning operation is employed to provide NSC header files and DRM licenses to users in response to them making content requests. The header files and licenses are sent over a separate data channel and in advance of the broadcast content.
