ENCODING DEVICE, ENCODING METHOD, DECODING DEVICE, DECODING METHOD, AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2022/004376

Kind Code:

A1

Abstract:

The present technology relates to an encoding device, an encoding method, a decoding device, a decoding method, and a program which enable encoding in which running disparity is controlled and transmission efficiency is high. The present technology is provided with: a scrambling unit that scrambles an input data sequence; a calculation unit that calculates a first running disparity for the data sequence scrambled by the scrambling unit; a determination unit that determines whether to invert the data sequence scrambled by the scrambling unit, on the basis of the first running disparity calculated by the calculation unit and a second running disparity calculated at a time point before the first running disparity; and an addition unit that, on the basis of the determination result by the determination unit, inverts or does not invert the data sequence scrambled by the scrambling unit, and outputs the data sequence with a flag indicating the determination result added thereto. The present technology can be applied to a device that performs communication according to SLVC-EC specifications.
