Abstract
The invention consists of a method for controlling the use of a device for viewing audiovisual transmissions, aiming to limit the duration of viewing audiovisual transmissions during determined time periods. The method comprises steps of inserting and displaying a first and a second duration, which define a maximum viewing time. The method also comprises a step of displaying values of binary indicators associated with determined time periods, and a step of inserting a binary indicator value for each time period, the binary value allocating the first or the second duration at this time period in order to define the viewing duration authorized during this time period. The invention also relates to the viewing device for implementing the method and a graphics interface for presenting parameters of the method.
