Abstract
A separate data stream allows encoding of an overlay image, which is to be superimposed on images of a video sequence. The pixels of the overlay image can be transparent or have a text color, a shadow color, or an intermediate color either between the text color and the shadow color, or between the shadow color and the color of the corresponding pixel in the underlying video image. The intermediate colors provide for antialiasing. In addition, a color selection circuit allows selection of the next color from a pool of 9 colors, using a 3-bit field.
