摘要

PURPOSE: A system and method for protecting the output of a video card is provided to overcome a software attack, especially for the case of attack performed by a defective application executed on a user's machine. CONSTITUTION: A graphic processor unit(308) processes the video data rendered to a monitor. A video memory(310) operatively linking with the graphic processor unit(308) stores the data processed or to be processed by the graphic processor unit(308). A display converter(312) converts the digital data into a used signal when the data is rendered to the monitor. A decoder decodes the pixel data provided to the display converter.
