    • 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.
    • 本发明涉及一种处理压缩数字图像的方法。 为每个图像块存储随机访问表。 随机访问表包括比特流中的块的开始处的比特缓冲器状态信息和用于定义要继续从比特流读取数据的位置的指示符。 响应于需要解码块的至少一部分,从随机访问表中检索块的比特缓冲器状态信息。 基于检索到的比特缓冲器状态信息和从基于指示符定义的位置开始从编码比特流读取的信息来解码遵循DC系数的期望数量的系数。
