Abstract:
A method comprising:associating a plurality of first counters with a plurality of pixel byte values, each counter associated with several pixel byte values; incrementing a count in each first counter upon an occurrence of an associated pixel byte value in a first idle frame; selecting a first set of pixel byte values based on the counts in the first counters; associating each of the first set of pixel byte values with one of a plurality of second counters; incrementing a count in each second counter upon an occurrence of the associated pixel byte value in a second idle frame; selecting a second set of pixel byte values based on the counts in the second counters; associating each of the second set of pixel byte values with a code; and compressing a subsequent idle frame by replacing at least a minimum number of the second set of pixel byte values in the subsequent idle frame with the associated code.
