- the values of E2 are modified by adjustment of the audio and / or video parameters, according to the user criteria retrieved by the PFS platform.
- Step E'2 being optional, it is shown in dashed line in FIG.
- the modification E'2 comprises a modulation, with respect to a predetermined threshold which is a function of said at least one user criterion of the terminal, of the value of the audio and / or video parameter (s) that have been set at the end of step E2.
- the modulation implemented with respect to a predetermined threshold consists, for example:
- n predetermined 1 values of the audio and / or video parameters set according to the content
- the number of increments or decrementations to be performed is also possibly predetermined according to the profile of the user.
- the user UT has previously declared to the platform PFS that it is visually impaired, if for example two values VV and VV 3 were respectively allocated in step E2 to the contrast video parameters PV1 and PV 3 of color saturation, two predetermined multiplication coefficients are applied to the values VVi and VV 3 before sending, at E3, the adjustment instruction IRG.
- the modification E'2 comprises a replacement of the value of the audio and / or video parameter or parameters which have been set at the end of the step E2, by another value which is a function of at least one criterion related to the user of the terminal.
- these criteria are in the form of rules that complement or replace the automatic adjustments implemented in the device 100 of FIG.
- the user can impose on the device 100 a setting value of certain audio / video parameters, for example the volume and the brightness.
- the adjustment values are selected by the user by moving for example a cursor associated with each parameter.
- the user can impose on the device 100 a contrast value that he has the possibility of incrementing or decrementing according to his needs.
- the user can impose on the device 100 a value of low frequencies and a value of high frequencies, that he has the possibility of incrementing or decrementing according to his needs .
- Agnes has a small hearing loss on a particular frequency band. Agnippo configures her system so that the vocal frequencies of the contents that intervene in this band are shifted so that she can hear them better. Martin does not fully trust so-called "all-public" content for his children. He then configures his system so that all the unsuitable scenes are artificially masked by an automatic adaptation of the volume (cut sound) and the brightness of the image (black screen). Martin is thus more serene and reassured.
