Abstract:
1. 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 overscanned information contained in pixel data of the composite digital video data stream.
