An apparatus and method of intraframe encoding of digital frequency-domain data. The data comprises a plurality of slices each having a plurality of blocks. Each block has a DC component and a plurality of AC components. A first DC component value of each slice is encoded. Each subsequent DC component value of each slice is represented as the difference between it and the DC component value preceeding it. For lossless encoding, the initial DC component value of each slice and the differences are encoding using Golomb-Rice.
