This implementation uses seven pixels in the corner of the active video. The red and green values of these pixels are set to 0, and the blue values are set to 0 or 1 each frame. Each frame an additional blue pixel within the region is set to 1 to increment the checksum from 0 to 7. The advantage of this implementation is that each pixel's maximum value is (R 0, G 0, B 1). The disadvantage is that it requires a larger checksum region where these pixels will effectively appear black and cannot be used for other video content.
