A single pass through the data for one or more of the components in an image.
A marker segment that contains a start-of-scan marker and associated scan parameters that are
coded at the beginning of a scan.
One of the lossless or DCT-based coding processes defined in this Specification in which
each component of the image is encoded within a single scan.

The storage location where an index is stored which identifies the value of the conditional
probability estimate used for a particular arithmetic coding binary decision.
A progressive coding process in which the coefficients are coded with reduced

The coded representation from which the tables used in the encoder and decoder are
generated and their destinations specified.

data of another encoder process.

above (in lossless mode coding).
