ABSTRACT:
Reproducing characteristics of an audio sound are controlled by an audio controller8and reproducing characteristics of a video image are controlled by a video controller11. Whether or not a viewpoint of the user is directed to a display13side of a television receiver is detected by a viewpoint detector14. On the basis of a detection signal from the viewpoint detector14, a discriminating unit15discriminates which of a normal monitoring state, a “while watching” state, and the “concentration” state the present state corresponds to, and generates a control signal to control the reproducing characteristics so as to be adaptive to the state. If it is determined that the present state changes from the “while watching” state to the “concentration” state, a sound volume is reduced and the reproducing characteristics are automatically switched so as not to obstruct the concentration.
