Abstract
For an image data such as a motion picture image data composed of three hierarchical layers formed of slices, each of which having a plurality of macroblocks and one picture having a plurality of the slices, a synchronous word is adaptively inserted to each header of the slices and the picture according to a characteristic of the image data. It is possible to effectively perform the localization of errors. A synchronous word multiplexing system for coded image data inputs and codes image data, converts the coded data to a variable-length coded data, divides the image coded data into a plurality of data signals, and multiplies a synchronous word per a predetermined divided unit. Further, a timing signal for multiplexing synchronous words to the image coded data is generated based on a characteristic data, and the timing of multiplexing synchronous words is controlled based on characteristics of the image data.
