Abstract
A video processing device includes a processor, a voltage conversion circuit, and a Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs (SCART) chip. The processor is operable to process video signals, and control a GPIO (general purpose input output) pin to output different mode controlling signals according to different video signal formats. The voltage conversion circuit connected to the GPIO pin is operable to receive the mode controlling signals, and output different voltage signals according to the different format controlling signals. The SCART chip connected to the voltage conversion circuit is operable to receive the video signals and the voltage signals, and process the video signals according to the corresponding voltage signals.
