<p>A television receiver includes a character generator (63) for generating a character signal suitable for displaying a menu of various processing control choices, such as processing for monaural, stereophonic or second audio program reproduction, "on-the-screen" of a picture tube, and a control unit (53) for dynamically altering the contents of the menu in response to the signal conditions of a received television signal, such as the presence or absence of stereophonic or second audio program information. As a result, confusion to a user in selecting (59) a processing mode which is rendered ineffectual due to a particular signal condition is minimized.</p> |
