Abstract
Reproducing characteristics of an audio sound are controlled by an audio controllerand reproducing characteristics of a video image are controlled by a video controller. Whether or not a viewpoint of the user is directed to a displayside of a television receiver is detected by a viewpoint detector. On the basis of a detection signal from the viewpoint detector, a discriminating unitdiscriminates 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.
