DECODING MEDIA CONTENT AT A WIRELESS RECEIVER |
摘要 |
A wireless receiver (17), in the form of a mobile telephone, comprises a DAB receiver (31) and a GSM/GPRS transceiver (29) which enables bi-directional point-to-point data communications via a service provider (55). The DAB receiver (31) 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 (47) on the wireless receiver (17), a provisioning operation is employed to provide NSC header files and DRM licences 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.
