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. To address specific sociological profiles, and to save bandwidth, 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 viewer's profile.

摘要： The invention relates to a process for allocating bandwidth to a plurality of data streams on a communication channel of a broadcasting network. The bandwidth of each stream transmitted from a communication office is defined by an effective allocation value.
This value depends on a predefined allocation value and is recalculated when the transmission of another stream is modified. The effective allocation value for each stream is calculated as a function of strategies and can be adjusted as a function of the actual transmission of the data on the communication channel.
The subject of the invention is also the communication office which allocates the bandwidths of each stream according to the process.
