Abstract: An improved interactive network system is provided that allows the Network Operator to control the transfer of information to and from the network end users, the system preferably using triggers or markers embedded within the programming broadcast to users via the network. As a consequence of this system, the Network Operator is able to efficiently garner revenues from third parties transacting business over the network and to control the look and feel of programming offered to network users. Additionally the system can be used as a means of limiting network access, filtering programming, providing on-screen graphics or audible signals for particular programming types or providers, bookmarking programming, profiling network users, targeting advertising, and simplifying network transactions.

Abstract: The invention relates to a process for controlling the flow of information exchanged between at least one station for transmitting interactive programs and a plurality of interactive terminals. According to the invention, during each interactive program, 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.
