Zusammenfassung:	A method of selecting transform segments from a data stream (426), the stream comprising a plurality of blocks each comprising a plurality of transform segments, is disclosed. The selection reorders the transform segments in a block, and comprises, for each said block, steps of selecting a first set of transform segments (426-432) suitable for direct inverse transformation to form a first data segment, selecting a second transform segment (1612) which is directly inverse transformable given availability of the first set (426-432), identifying a third transform segment (1608, 1610) which is not directly inverse transformable given availability of the first set (426-432) and the second transform segment (1612), and selecting a fourth transform segment (1610, 1608) which is required to support direct inverse transformation of the third transform segment (1608, 1610).
