VIDEO DISC PLAYER HAVING IMPROVED SQUELCH SYSTEM

摘要

Suppression circuits are placed an either side of the signal processor to eliminate distorted pictures or noise on the screen during transient conditions. These circuits are actiavated by a microprocessor in the recorder control unit. The suppressor before the video processor is active in the transition from pause to replay. The other suppressor cancels picture output when a new disc is being started, and covers the time from bringing the stylus onto the disc and establishing a steady signal condition. During the suppression times the control unit establishes the necessary control signals for steady operation.
