摘要： 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.

摘要： The interactive multimedia devices is based on network structures involving: a broadcasting network (120) and a return path network (140). On the broadcasting network, the interactive data are multiplexed with the broadcast audiovisual signals so as to offer interactivity to connected end-users on the return path network. The information provided by the viewers is homogenized owing to a standardized format stored in the terminals and in the service provider viewer database. In this way, it is possible to select a specific terminal or a category of viewers by using their profiles and not by using their physical addresses and to allow the viewer to react in a very short time in an interactive application mainly for interactive applications dedicated to commercial purposes. To address specific sociological profile, and to save bandwidth, a criteria file called a filter is attached to the digital data multiplexed with the audiovisual signals. Then, each operational interactive terminal receives the digital data with an attached filter. The interactive terminal applies the script of the filter to the criteria included in the filter and to the criteria contained in the viewers profile registered during the installation phase in order to enable the interactive connection.
In another implementation, a plurality of filters, let's say a number N, is associated with a single interactive application. In such case, the comparison continues until one of the N filters match the profile stored in the terminal permanent memory. If one of the filters matches the viewer's profile, the interactive application is executed, else the application is ignored. In this way, a plurality of categories of viewers can interact. A plurality of filters can be associated with an interactive application with different contents. To each filter corresponds a content. These contents are displayed if the corresponding filters match the viewers profile.
