ABSTRACT:
A preferred method includes the step of receiving multiple digital video data streams. Preferably, a first of the multiple digital video data streams contains processed pixel data corresponding to at least a portion of the image to be rendered, and a second of the multiple digital video data streams contains processed pixel data corresponding to at least a portion of the image to be rendered as well as information, such as a chroma-key value, associated with at least some of the processed pixel data. The embodiment also preferably includes the step of combining the multiple digital video data streams into the composite digital video data stream by referencing the chroma-key values. Devices also are provided.
