A system and method implemented in an interactive television system for scheduling delivery of modules of interactive television applications from a broadcast station to a receiving station. In one embodiment, the system calculates a start time from a predetermined end time and transmission interval for a module. In other embodiments, a transmission interval may be calculated instead of being predetermined, or all of the scheduling information may be explicitly provided to the broadcast station. The module is packetized and transmission of the packets for the module is begun at the corresponding start time. All of the packets except the last packet are transmitted within the transmission interval (i.e., between the start time and the delivery time.) The greater the transmission interval, the greater the flexibility the broadcast station has to schedule delivery of the packets and modules. The last packet is held until the scheduled delivery time and is then transmitted. Because a module is considered to have been delivered to the receiving station when the last packet is received, the delivery time of the module is controllable to within the limits of the last packet's delivery.
