  • Source coding to provide for robust error recovery
    Patent number: 6170074
    Abstract: Data is encoded to maximize subsequent recovery of lost or damaged compression constants of encoded data. In one embodiment, a compression constant is used to define a randomization pattern and the data is randomized using the randomization pattern. In one embodiment, a bit reallocation process and code reallocation process are performed on the data to randomize the data.
