Abstract

The subtitle data encoding apparatus according to the present invention is used in a video image transmission system. The apparatus creates loading blocks from relative position information by sampling an input bit stream at a frame interval. The loading block corresponds to a pixel data block and contains changeover position information which updates a change position, delays the update operation and sets the length of the delay. The address used to access a color lookup table for displaying subtitle data is changeable at the change position to access different display data stored therein. The pixel data block is encoded from subtitle data and the loading blocks and pixel data blocks are combined for transmission. The changeover position information can also be used to progress a color-wipe operation.
