Claim 16:
17. A method, comprising:
deriving, from an array of sample values, sample range flags each indicative of whether one or more sample values of the array of sample values lie in a predetermined range of sample values;
encoding, in a first encoding mode, the array of sample values, at least in part, by encoding the sample range flags to an output data stream;
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;
comparing the predicted state of the group of sample range flags with the actual state of the respective sample range flags for the given array of sample values; and
in response to the comparing step, encoding the given array of samples values in a second encoding mode by encoding to the output data stream a predetermined number of indicator flags, fewer than the group of sample range flags, to indicate 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.
