DEVICE AND METHOD FOR ENCODING AND DECODING INITIAL DATA Russian patent published in 2017 - IPC H03M7/30 H03M7/40 H04N19/91 

FIELD: physics.

SUBSTANCE: encoder (20) for encoding data (D1, 10) to obtain corresponding encoded data (E2, 30) containing information about the frequencies, probabilities, or range values of different symbols to be represented in the encoded data (E2, 30), wherein the said information indicates the symbols, to which the said frequencies, probabilities, or range values relate, wherein the encoder (20) is able to include additional information into the encoded data (E2, 30), indicating, whether the encoded data (E2, 30) include information about the frequencies, probabilities, or range values for the said different symbols.

EFFECT: increasing the efficiency of the encoded data compression.
