Abstract
The invention is generally but not exclusively concerned with problems associated with production of interactive television, particularly an interactive televised auction, where input must be obtained from a plurality of users and broadcast output must be provided based on live user input. However, solutions provided by aspects of the invention are not limited to such a use and may be more generally applied.
