ABSTRACT:
A composite video signal including a timing component and a caption video signal having no timing component are combined to form a resultant video signal for application to a television receiver. The caption signal is produced by a character generator that is normally synchronized with the timing component of the composite video signal. A substitute timing signal is supplied to the character generator and also added to the player output signal under conditions which interrupt the timing component of the composite video signal whereby captions may be continuously displayed on the television receiver notwithstanding partial or total interruption of the composite video signal.
