ABSTRACT:
A system (1) for reproducing picture signals from a record carrier (3) in the form of a tape on which the reproduced picture signals are stored in juxtaposed inclined tracks comprises a character generator (23) for inserting character signals into reproduced picture signals. The character generator (23) is enabled to insert character signals depending on a starting-pulse edge (S1 S2, S3) generated by means of a control device (25), which edge is generated at a time interval from a position-pulse edge (P1, P2, P3) which is each time generated by means of a pulse generating device (11) at the beginning of the scan of an inclined track. The line pulses (H) extracted from the reproduced picture signals are applied to the control device (25), which comprises a detector device (35) for detecting in each picture signal the same number line pulse, and the control device (25) generates the starting-pulse edge for the character generator (23) depending on each time the same detected line pulse, which ensures that insertion of the character signals by this generator is always started at the same line.
