1. Method for transmitting receiver resident software module updates in a video transmission system comprising the steps of:
- providing an announcement of an interactive television service on a first predefined IP multicast address;
providing a trigger for at least one of said interactive television service and a content transmission on a first range of IP multicast addresses;
providing an announcement of a receiver resident software module update on a second predefined IP multicast address different from said first predefined IP multicast address, said announcement describing a download address of an upcoming download of said receiver resident software module update, said download address being chosen from among a second range of IP multicast addresses, exclusive of the first range;
providing said download of said receiver resident software module update on said download address, said first and said second ranges of IP multicast addresses are split according to data type, said data type being one of said at least one of said interactive television service and a content transmission or said receiver resident software module update.

Abstract
The invention concerns a method for transmitting binary data in a video transmission system. The method comprises the steps of providing ATVEF announcements on a first predefined IP multicast address; providing ATVEF trigger and/or content transmission on a first range of IP multicast addresses; providing non-ATVEF announcements on a second predefined multicast address different from said first address; and providing non-ATVEF data transmission on a second range of IP multicast addresses, exclusive of the first range. The invention also concerns an emitter and a receiver for implementing the method.
