Encoding devices, methods and programs that encode with high transmission efficiency by controlling a running disparity are disclosed. In one example, an encoding device includes a scrambling circuit that scrambles an input data string, a calculation circuit that calculates a first running disparity of the scrambled data string, a determination circuit that determines whether or not to invert the scrambled data string on the basis of a first running disparity calculated by the calculation circuit and a second running disparity calculated at a time point before the first running disparity, and an addition circuit that inverts or non-inverts the scrambled data string on the basis of a determination result by the determination circuit, adds a flag indicating the determination result, and outputs the data string. The technology can be applied to devices that perform SLVS-EC standard communication.

Encoding device, encoding method, decoding device, decoding method, and program

The technology relates to an encoding device, an encoding method, a decoding device, a decoding method, and a program enabling encoding with favorable transmission efficiency with a controlled running disparity. A calculation section divides inputted data into N or M bits to calculate a first running disparity of an N or M bit data string. A determination section determines whether the data string is inverted based on the first running disparity calculated by the calculation section and a second running disparity calculated therebefore. An addition section inverts or non-inverts the data string based on a determination result by the determination section to add a flag indicating the determination result for outputting. The determination section determines not to perform inversion when the data string is a control code. The addition section adds the flag assigned to the control code. The technology is applicable to a device communicating in an SLVS-EC specification.

Encoding and decoding devices, methods and programs are disclosed. In one example, decoding is provided by dividing input data into data strings of N bits, the data strings including a first data string, calculating a running disparity for the data strings, determining whether the first data string is to be inverted based upon the calculated running disparity, setting a flag for the first data string to a first value when it is determined that the first data string is not to be inverted, and setting the flag for the first data string to a second value and inverting the first data string when it is determined that the first data string is to be inverted, and outputting the first data string. The technology is, for example, applicable to a device communicating in an SLVS-EC specification.
