Abstract
A television receiver includes conventional systems for receiving a broadcast type signal and displaying the received signal upon a cathode ray tube. Vertical and horizontal scan system oscillators and controls produce vertical and horizontal scan signal synchronized to the reference sync signals. A scan clock system cooperates with the horizontal oscillator and control system to produce horizontal scan related signals which are synchronized to the CRT scan.
