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.
