Abstract:
1. A method comprising: receiving a block of transform domain coefficients and corresponding error flags, wherein at least one coefficient is erroneous due to transmission of the coefficients; estimating an initial value for each erroneous coefficient; decoding the erroneous coefficients of the block into estimated pixel values using the initial values of the coefficients to create predicted decodings of the block where there are errors in the coefficients and decoding non-erroneous coefficients of the block into error-free pixel values using received values of the coefficients to create partial decodings of the block where there are no errors in the coefficients; updating the value for each erroneous coefficient based on the partial and predicted decodings of the block; and updating the estimated pixel values of the block using the updated values of the coefficients.
