Abstract

As the offer of television programs increases, it is imperative to find means to gain access rapidly to the emissions one prefers. Furthermore, the offer is not addressed always to all users, for example, when it concerns emissions for adults.

The objective of the invention is to propose a processing system of a television program grid comprising above the group of information of the television offer and below the information particular to a group of users. Each user group has a set of parameters that are divided into several sets, each set corresponding to a filter layer allowing to select the category or categories of desired information.

Claims

1. A processing system of a television program grid comprising on one side the information of the television channels information, and on the other part the channels information particular to a group of users as well as parameters defining a user profile, these parameters are divided into several sets of parameters, each set corresponding to a filter layer allowing to select the category or categories of desired information, characterized in that, the first layer defining a global restrictive filter (CF) is defined by the manager of the system and the following layers defining a filter particular to a group of users contain filtering short commands and defined by at least one member of the group of users.

2. A system according to claim 1, characterized in that the following layers comprises parameters associated to one or several of the activation or disconnection functions of filtering of information categories.

3. A system according to claim 2, characterized in that these functions comprise the adding, the suppression or the definition of one or several information categories.

4. A system according to claim 3, characterized in that these functions are activated by specific keys on a remote control.

5. A system according to claims 1 to 4, characterized in that the following layers comprise an intermediate layer (IF1 . . . IFn) and a user layer (U1 . . . Un).

6. A system according to claim 5, characterized in that the intermediate layer and the global layer are protected by a same password.

7. A system according to any of the previous claims, characterized in that when starting the system it selects the user group having the most restrictive filtering.
