An integrated graphics processor provides a type of universal programmable synchronization signal generation that provides a plurality of different formats of display synchronization signals. In one embodiment, the integrated graphics processor includes a graphic and video blender that mixes image layers together prior to output for display. The graphics and video blender receives graphics and video data obtained from a frame buffer that may contain multiple formats of data, such as data in different color spaces, such as in a YUV color space (i.e., as per ITU-R BT709 or ITU-R BT 601), and in RGB color space. The integrated graphics processor also includes an integrated (internal or on-chip) programmable embedded synchronization signal generator operatively coupled to the graphic and video blender, to provide a plurality of different formats of display synchronization signals for blended information based on a type of display device. Accordingly, the integrated graphics processor can be programmed to provide suitable luma and chroma display information for different types of display devices, such as standard television displays, HDTV displays, and other displays that may require, for example, embedded synchronization signals, an embedded multilevel synchronization signal, or a separate synchronization signal.
