A decoding device is provided, which can minimize the number of coded data addition requests by the decoding device, reduce processing time to prevent delay, and minimize frame rate reduction. The decoding device performs data reproduction by performing error correction of data of a predicted image using coded data which is an error correction code generated based on original data. The decoding device includes a coded bit receiving part, a preset value generating/updating part, a decoding part that performs a decoding process based on a preset value or a predicted value, and coded bits, and a bit addition request determining part that determines whether or not there is a need to request additional coded bits from decoding process results from the decoder. When it is determined to perform a decoding process with additional coded data, the preset value generating/updating part updates the preset value based on previous decoding process results.
