摘要: PROBLEM TO BE SOLVED: To provide a system and method for protecting multimedia data in certain format transmitted via communication channel.SOLUTION: In computer implementation method, series of video images is logically divided into plurality tiles, each tile has position that defined within the images, continuously identical between continued images. One or more tiles image are encoded using first compression format, remaining second format. The depends on before by and/or forward error correction (FEC) code generated FEC to client together with format.SELECTED DRAWING: Figure 10a
