摘要： The invention relates to a process for controlling the flow of information exchanged between at least one station for transmitting interactive programmes and a plurality of interactive terminals.
According to the invention, during each interactive programme, each terminal is sent a group of data intended to set up a protocol for establishing interactive communications between said transmission station and said terminals.

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.
