Schaltungsanordnung und Verfahren zur Erzeugung von Vertikal- und Horizontal-Synchronsignalen für eine Zeichenerzeugungsschaltung

摘要

The circuit includes a vertical synchronizing signal generator (100) for generating a vertical synchronizing signal by receiving a composite signal and a horizontal synchronizing signal generator (200) for generating the horizontal synchronizing signal by counting 4fsc clock pulses using the vertical synchronizing signal as a reset signal. This allows characters to be generated without frame jitter.
