Patent ID: 8643781

Claim:
A system for driving a plurality of different types of video devices, the system comprising: a System on a Chip (SoC) that includes: a Liquid Crystal Display (LCD) controller circuit configured to drive the different types of video devices including at least digital visual interface (DVI) driving circuit and video graphics array (VGA) driving circuit, and generate digital video data, a first synchronization signal for controlling a first characteristic of the digital video data, and a second synchronization signal for controlling a second characteristic of the digital video data; and a delay circuit configured to variably delay the first synchronization signal and the second synchronization signal relative to the digital video data to generate a delayed first synchronization signal and a delayed second synchronization signal, the delayed first synchronization signal and the delayed second synchronization signal compensating a delay caused by a Digital-to-Analog Converter (DAC) converting the digital video data to analog video signal.
