Abstract
Abstract The present invention relates to a television set, supplied with a remote control unit, comprising a reduced number of command keys for controlling the functions in a plurality of functional modes, among which a first mode dedicated to controlling the normal television reception (TV), and/or a second mode for controlling the teletext reception (TXT), and/or a third mode for controlling the functioning of an auxiliary device (VTR) connected to the television set, and in which one of the keys (DISP) is provided for activating the display on the television screen of a plurality of useful symbols for controlling the functions; the characterising principle of the invention consists in the fact that the symbols are represented by symbolic complex figures united in a plurality sequences corresponding to said functional modes and that each sequence is displayed according to the functional mode in use and said symbolic complex figures are displayed in such a way so as not to substantially disturb the viewing of the image reproduced on the television screen, even though being clearly visible, and that they comprise all the symbols necessary for the control of all the provided functions of the selected operating mode.
