Abstract
A method and apparatus for processing video and graphics data is accomplished by receiving display data that includes at least one of video data and graphics data. If the display data includes video data, the video data is converted into graphics formatted video data when a first control signal is in a first state. The graphics formatted video data, which is now in a format consistent with the computer monitor (e.g., an RGB video format), is then provided to the computer monitor based on the enablement of the first control signal. Alternately, or in addition to, the graphics data may be provided to the computer monitor. If the display data includes graphics data, i.e., computer generated data for display on a computer monitor, the graphics data is converted into video formatted graphics data when a second control signal is in a second state. In this conversion, the graphics data, which is in a RGB format, is converted into a video format, e.g., a YUV data format. Having made the conversion, the video data and/or the video format graphics data is provided to a television based on the second control signal.
