Abstract
A television (TV) receiver which receives TV signals in a plurality of TV frequency bands includes apparatus for developing an accentuated and uncontaminated on-screen tuning indication. Specifically, a blanking device is responsive to a tuning signal for eliminating the display of a portion of the TV picture for the duration of a pulse signal. The pulse signal is delayed in time relative to a deflection signal by a time related to the tuning signal so that a blanked bar is generated in the TV picture. A tuning indicator device causes a predetermined display unaffected by the TV picture during the blanked portion of the TV picture.
