Zusammenfassung:The present technology pertains to an encoding device, an encoding method, a decoding device, a decoding method, and a program that enable encoding with high transmission efficiency by controlling polarity deviation. The technique comprises: a scrambling unit for scrambling an input data string; a calculation unit that calculates a first polarity deviation of the data string scrambled by the scrambling unit; a determination unit that determines whether to invert the data string scrambled by the scrambling unit, based on the first polarity deviation calculated by the calculation unit and a second polarity deviation calculated at a point in time before the first polarity deviation; and an adding unit that inverts or does not invert the data string scrambled by the scrambling unit, adds a flag indicating a result of the determination, and outputs the data string, based on the result of the determination by the determining unit. The present technology can be applied to a device that performs communication accordi
