As television programs increases, it becomes necessary to find means for rapidly accessing the users' preferred programs. Furthermore, television programs are addressed to different types of users such as children and adults. The proposed system processes a program grid comprising at a higher level the whole information on programs and at a lower level, information specific to a users group as well as parameters defining a user profile. The parameters are divided into several sets of parameters, each set corresponding to a filter layer allowing selecting a category or categories of required information. The first layer, defining a global restrictive filter, is defined by an administrator of the system and the following layers, defining a filter specific to a users group and containing filtering short commands, are defined by at least one member of the users group. |
