Patent ID: 8392801

Claim:
A decoding device that performs data reproduction by performing error correction of predicted data using coded data, the decoding device comprising: a coded data receiver that receives a first signal including transmitted first coded data, which includes a first error correction code based on original data; a prediction value generating part that generates predicted data; a preset value generating/updating part that performs a process for generating or updating a preset value indicating a degree of reliability of error correction; a decoding part that performs a decoding process based on the preset value and the predicted data, and the first coded data; and an addition request determining part that performs a process for determining whether or not there is a need to request second coded data based on a result of the decoding process of the decoding part, wherein the preset value generating/updating part performs the process for updating the preset value based on a result of a previous decoding process if the decoding part determines to perform a decoding process with the second coded data.
