Abstract
A method is provided in one example and includes receiving overlay data at a dual frame buffer module, which interacts with a video data buffer and an alpha data buffer. The method can also include storing the overlay data as a first video data in the video data buffer if an indicator is not present in the overlay data; and storing the overlay data as a second video data in the alpha data buffer if the indicator is present. In more specific implementations, the indicator is a pixel in a non-viewable area of the overlay data.
