摘要：Video data encoding apparatus in which arrays of video data are reordered forentropy encoding includes a frequency domain converter for generating a frequency

domain representation of data derived from an input video signal, the frequency domainrepresentation including an array of plural frequency domain coefficients in respect ofeach image area. The apparatus includes a selector for selecting a reordering patternfrom a set of two or more candidate reordering patterns, for use in reordering the arrayof frequency domain coefficients. The apparatus includes a data scanner for changing theorder of the frequency domain coefficients according to the selected reordering patternso as to generate reordered coefficients. The apparatus further includes an entropyencoder for entropy-encoding the reordered coefficients.
