Abstract
A novel on-screen display system for TV incorporated into an application-specific MCU (microprocessor control unit) is described. It uses the PLL (phase-locked loop) technique and is compatible with all currently known scanning standards which are detected automatically. The circuit is developed so that the characters are stable regardless of system change. Special techniques are used to minimize the horizontal jitter of the display
