FIELD: physics, computing science.
SUBSTANCE: invention relates to coding, decoding and code transformation, and can be used for correction of digital bit stream read out from the drive's head of DVD. Technical result is simplification of device making stochastic correction of RLL (2,10) rule errors in the bit stream of DVD. The device contains sequential synchronous data shift register, register of shift's inhibit, control logic with error detection chains, set for detection of the errors of RLL (2,10) rule and with error correction chains, logic element AND.
EFFECT: simplification of device, which carries our probabilistic error correction of RLL (2,10) rule in the bit stream of DVD.
