摘要：
Graphics in the same compressed digital format as that of a target video image are combined, on the fly, by an application. Combination is performed by frame modification or overlay techniques. In the preferred embodiment, the compressed video image format conforms to an MPEG-2 compression standard. A base image is produced by an I-frame, and MPEG-2 graphics elements formed either by modifying the I-frame or overlaying the I-frame with one or more P-frames.
