Abstract
A television channel selection monitoring apparatus for identifying the broadcast channel to which a television receiver means is tuned at any given time is disclosed. Instead of relying for the channel identification on the local oscillation frequency at the tuner of such television receiver means, the apparatus of the present invention utilizes the recognition of the channel identification number superimposed on the video signal received through the selected channel so that the image of the superimposed channel number may appear, for a certain duration following the channel selection, at a predetermined area of the image corresponding to the video signal.
