Abstract
A system and method for allowing an end-user to interact with a system in order to execute an application. Multiple application packets are broadcast to a plurality of end-users, such that the upstream transmission of data from end-users is greatly reduced. Each end-ser further receives media packets, whereas visual objects relating to the application can be displayed on an end-user display unit with visual objects originating from the media packets.
