The present invention relates to a method for processing a compressed digital image. A random access table is stored for each image block. The random access table comprises bit buffer state information in the beginning of a block in the bit stream and an indicator for defining a position at which reading of data from the bit stream is to be continued. The bit buffer state information of a block is retrieved from the random access table in response to a need to decode at least portion of the block. A desired number of coefficients following the DC coefficient is decoded on the basis of the retrieved bit buffer state information and information read from the encoded bit stream starting from the position defined on the basis of the indicator. |
