Abstract
According to the present invention, there is provided a coding apparatus including an input unit for inputting image data, a coding unit for coding the image data input by the input unit, and an error detection/correction coding unit for performing error detection coding or correction coding of the image data coded by the coding unit, the coding unit coding the image data by selectively using first and second coding modes based on different coding methods, and the error detection/correction coding unit performing different error correction and correction coding operations depending on the coding mode. In addition, there is provided a decoding apparatus for inputting coded data which is coded by selectively using first and second coding modes based on different coding methods and has undergone different error correction coding operations depending on the first and second coding modes, and coding mode data indicating a specific one of the first and second coding modes by which the coded data has been coded, and decoding the coded data, including a detection unit for detecting the coding mode data, and an error code correction unit for performing error code correction of the coded dat…
