Abstract

A method and corresponding apparatus first encodes digital data by grouping the data into a data segment. A particular length of the data segment is placed into check information encoded within the data segment. The encoded data segments are then transmitted from a first computer to a second computer that receives and decodes the data segments. The second computer decodes the received data segments dependent on the particular length information that was placed in the check information during encoding of the data segment. Decoding dependent upon the particular length information provides dependable synchronization and improved resistance to the introduction of errors, accordingly.
