Abstract: The present invention provides a multiplexing device, multiplexing method, and multiplexing program that allow an optional character string to be easily multiplexed with video online. The multiplexing processing unit multiplexes a dummy character string with the respective encoded data for video and audio. The multiplexed data are stored in the multiplexed data storage unit. The multiplexing processing unit stores the position (first dummy point) in which the dummy character string data were stored in the dummy point storage unit. The character string substitution processing unit substitutes the dummy character string data for the optional character string data to be inserted that has been input from the character string input unit on the basis of a first dummy point. The substituted multiplexed data are output as a multiplexed file from the file generation processing unit.

Abstract: An image processing system which efficiently generates a desired special effect with a simple circuit. In order to add special effects to a given source picture, a target area specifying unit first specifies a target area, as part of the given source picture, which is to be subjected to a special effect generation process. The source image is coded by an image data coding unit, and the resultant coded data is then modified by a target data relocation unit, Here, part of the coded data, or target data in the target area, is extracted and relocated from its original field to a different field of the coded data. An image data transmission unit transmits the coded bitstream which contains the relocated target data. At the receiving ends, a target data extraction unit extracts the target data from the received coded bitstream, which is then saved into a target data storage unit.
