标准范围

ISO/IEC 22091:2002规定了无损压缩算法，以减少表示数据记录和文件标记所需的8位字节的数量。该算法被称为流无损数据压缩算法(SLDC)。ISO/IEC 22091:2002基于ISO/IEC 15220。它通过添加控制符号来扩展该算法，该控制符号允许不同大小和可压缩性的记录以及文件标记被有效地编码成输出流，该输出流几乎不需要或不需要用于以后解码的附加控制信息。根据ISO/IEC 11576分配给该算法的数字标识符是6。

ISO/IEC 22091:2002 specifies a lossless compression algorithm to reduce the number of 8-bit bytes required to represent data records and File Marks. The algorithm is known as Streaming Lossless Data Compression algorithm (SLDC).

ISO/IEC 22091:2002 is based on ISO/IEC 15220. It extends that algorithm with the addition of control symbols that allow records of different sizes and compressibility, along with File Marks, to be efficiently encoded into an output stream which requires little or no additional control information for later decoding.

The numerical identifier according to ISO/IEC 11576 allocated to this algorithm is 6.
