BROADCAST DATA NETWORK SYSTEM

摘要

The invention relates to a system and method for the selective transmission of data to individuals or groups of viewing locations to thereby allow at selected times at least, the targeting of data which is more focussed or targeted to viewers at said locations. This is achieved by detecting and processing data which is indicative of the interaction of viewers with the receiving apparatus at each location and using this possibly in combination with other data, to assess characteristics of the viewers and then select the data to be transmitted to them.
