Abstract
A digital encoding subsystem encodes binary input data, which comprises payload data. The subsystem facilitates the preservation of the payload data destined for a temporary holding media, such as a transmission media or a storage media. A scrambler receives and scrambles given binary input data to produce given scrambled data. A criteria checker determines whether the given scrambled data satisfies desired criteria. The criteria may comprise a k-constraint, which represents the maximum number of consecutive zeros in a block of the given scrambled data. A de-scrambler receives and unscrambles the given scrambled data to produce given output data. A scramble modifier may be provided which changes the given scrambled data until the given scrambled data satisfies the desired criteria.
