Abstract
A method of selecting transform segments from a data stream ( ), 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 ( ) suitable for direct inverse transformation to form a first data segment, selecting a second transform segment ( ) which is directly inverse transformable given availability of the first set ( ), identifying a third transform segment ( ) which is not directly inverse transformable given availability of the first set ( ) and the second transform segment ( ), and selecting a fourth transform segment ( ) which is required to support direct inverse transformation of the third transform segment ( ).
