Systems and methods for rendering graphical data

A device for enabling production of a composite digital video data stream, the composite digital video data stream containing pixel data corresponding to an image to be rendered and being formed from multiple digital video data streams, each of the multiple digital video data streams being provided by a graphics pipeline, each graphics pipeline being configured to process pixel data corresponding to at least a portion of the image to be rendered, said device comprising:

• means for receiving the multiple digital video data streams, a first of the multiple digital video data streams containing processed pixel data corresponding to at least a portion of the image to be rendered, a second of the multiple digital video data streams containing processed pixel data corresponding to at least a portion of the image to be rendered and a chroma-key value associated with at least some of the processed pixel data;
• means for combining the multiple digital video data streams into the composite digital vide data stream by referencing the chroma-key values;
• means for selectively providing an output composite video data stream as a stereo video data stream;
• and
• a left channel and right channel;
• wherein said means for selectively providing an output composite video data stream comprises:
• means for allocating pixel data corresponding to each of the multiple digital video data streams to the left channel and the right channel based upon the chroma-key values of the pixel data.
