CA 2487396

An audio controller (8) controls audio reproduction characteristic and a video controller (11) controls video reproduction characteristic. A sight line detector (14) detects whether the user sight line is directed to a display (13) of a television receiver. According to a detection signal from the sight line detector (14), a judgment section (15) judges whether the current state is a normal viewing state, ~two-things at a time~ state, or the ~concentration~ state and generates a control signal for controlling the reproduction characteristic according to each of the states. When the ~two- things at a time~ state is judged to have been changed to the ~concentration~ state, the sound volume is reduced so that automatically switched to the state not causing interference.

Selon l'invention, une commande audio (8) commande une caract~ristique de reproduction audio et une commande vid~o (11) commande une caract~ristique de reproduction vid~o. Un d~tecteur de ligne de vision (14) d~tecte la ligne de vision de l'utilisateur lorsqu'elle est dirig~e sur un ~cran (13) d'un r~cepteur de t~l~vision. Selon un signal de d~tection ~mis par le d~tecteur de ligne de vision (14), une section d'~valuation (15) ~value si l'~tat courant est un ~tat de vision normal, un ~tat <= deux choses en mÚme temps >= ou un ~tat de <= concentration >= et ~met un signal de commande afin de commander la caract~ristique de reproduction en fonction de chaque ~tat. Lorsque l'~valuation de l'~tat <= deux choses enmÚme temps >= r~v­le qu'il a ~t~ chang~ en ~tat de <= concentration >=, le volume sonore est diminu~ de fa×on qu'il bascule automatiquement dans l'~tat n'entra¹nant pas de brouillage.
