Provided is a method and apparatus for compressing a text and an image. When compressing the text and image, it is possible to group valid lines with data into each line having a common element, and compress and encode the data of the valid lines. Accordingly, it is possible to reduce a data loss that may occur in a tactical communication environment with a poor channel state due to a bit sleep or a burst error. In the case of the text, it is possible to perform lossless compression on only a valid line with data and thereby improve compression efficiency. In the case of the image, it is possible to perform loss compression on valid lines, and then restore the partially damaged data using an ECC even when data is partially damaged. Accordingly, it is possible to improve compression efficiency and the entire data transmission success rate.
