Managing ambient light according to the programme

A method for managing ambient light, implemented in a set-top box which is connected to a viewing device and to a lighting device arranged to adjust ambient light, the management method comprising the steps of:

• detecting a start of a broadcasting of a first current programme;
• accessing a light parameter base comprising reference values of light parameters associated with programme metadata;
• selecting, in the light parameter base, first current values of said light parameters, which are associated with programme metadata corresponding to the first current programme;
• transmitting a first command to the lighting device, such that the lighting device adjusts the ambient light according to said first current values of the light parameters,
• the light parameter base comprising first reference values of the light parameters associated with first programme metadata, said first reference values being defined by the user, the set-top box being arranged to:
• receive a second command from a user who wishes to adjust the ambient light while a second current programme is being broadcast;
• producing second current values of the light parameters according to the second command;
• transmitting a third command to the lighting device, such that the lighting device adjusts the ambient light according to said second current values;
• storing the second current values in the light parameter base by associating them with metadata of the second current programme, such that the first reference values thus comprise the second current values, and the first programme metadata thus comprise said metadata of the second current programme.
