In a "mobile television" broadcast network (eg. DVB-H or 3G WLAN), targeted advertising and marketing messages are sent to users of mobile multi-media devices 6 according to profile information 23, with a preallocated amount of resources being used for messages in order to view the content from source 12. Upon request by user 6 for content from 12, account management system 10 and content management system 20 determine if the content delivery can be "sponsored" by the provider 18, ie. the required resources can be offset instead of user 6 paying for all of the content via a subscription fee, and forms a message packet with embedded DRM keys if so. Feedback from the user can also be rewarded with free or subsidised content. This allows provider 18 to carry out a message delivery campaign based on eg. users' demographics or purchase history, provides an improved audience model compared to eg. Nielsen ratings, and makes viewers more valuable to the content provider compared to traditionally broadcasting the same advertising messages to all viewers. |
