Patent ID: 7030891

Claim:
A method for producing a composite digital video data stream, the composite digital video data stream containing pixel data corresponding to an image to be rendered, said method comprising the steps of: receiving 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; combining the multiple digital video data streams into the composite digital video data stream by referencing the chroma-key values; and selectively providing an output composite video data stream as a stereo video data stream; wherein the step of selectively providing an output composite video data stream comprises the steps of: providing a left channel and right channel; and 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.
