  • Publication number: 20170134121
    Abstract: The present embodiments provide a method and an apparatus for determining a frame boundary of an FEC frame, and a decoding system. The method includes receiving data, where the data includes N+P consecutive symbols, N consecutive symbols constitute a first data block, and N consecutive symbols constitute a second data block; obtaining s parameter values corresponding to the first data block. The method also includes determining a first iterative item and a second iterative item and determining, according to the s parameter values corresponding to the first data block, s parameter values corresponding to the second data block. Additionally, the method includes determining, according to the s parameter values corresponding to the second data block, whether the second symbol is a frame boundary of an FEC frame.

  • Patent number: 7755787
    Abstract: A method for managing a plurality of printers shared among at least one user is provided. At least two of the plurality of printers are of the same model. The method includes configuring the at least two of the plurality of printers to report a common serial number by setting a serial number flag in a memory unit of the printer to a predefined value. When a computer is connected to the printer, the printer reports the common serial number to the computer.
