Abstract: A system and method for searching for image data using a keyword. The system and method perform the operations of: inputting a search word, determining whether the search condition of the inputted search word is a basic search, converting the inputted search word into a code, searching for a sequence header (SH) of compressed image data, and comparing the search word, which has been converted into code, with an information code stored at the sequence header (SH) in order to determine whether the inputted search word is present. The system and method further perform the operations of storing a picture number of the sequence header (SH) if the search word is present, searching for image data corresponding to the stored picture number, determining whether found image data is a still picture or a moving picture, and if the image data is a still picture, displaying the still picture, or if the image data is a moving picture, reproducing the moving picture.
