<p>The nature of entropy coding is such that a corrupt JPEG image cannot be decompressed beyond the point of corruption unless it contains restart markers. A restart marker stops and restarts the entropy coding algorithm so that, if a JPEG image is corrupted, decompression can resume at the next marker. Thus, adding more restart markers improves the fault tolerance of the JPEG image, but adding too many restart markers can adversely affect the compression ratio and performance.</p>

<p>In typical JPEG images, an MCU (Minimum Coded Unit) is the minimum set of interleaved "data units" (8x8 DCT blocks if the image is lossy or samples if the image is lossless) necessary to represent at least one data unit per component. (For example, an MCU in an interleaved lossy JPEG image that uses 4:2:2 subsampling consists of two luminance blocks followed by one block for each chrominance component.) In single-component or non-interleaved JPEG images, an MCU is the same as a data unit.</p>
