Claim 18:
19. A method, comprising:
decoding, in a first decoding mode, to decode an array of sample values, at least in part, from sample range flags in an input data stream each indicative of whether one or more sample values of the array of sample values lie in a predetermined range of sample values;
predicting the state of a group of the sample range flags for a given array of sample values, the group being at least a subset of the sample range flags; and
decoding the given array of samples values in a second encoding mode in which the data decoder is configured to detect in the input data stream a predetermined number of indicator flags, fewer than the group of sample range flags, indicating whether the predicted state of the group of sample range flags is the same as the actual state of the group of sample range flags for the given array of sample values.
