Patent ID: 8363751

Claim:
A communication method comprising: (a) dividing, in a communication device, one bit data group into a plurality of bit groups, the one bit data group being taken out from a plurality of bit data groups defined by a communication protocol for transmitting predetermined information, wherein inverting a value of a bit in the one bit data group modifies a representation of the information in the one bit data group without exerting an influence on the predetermined information; (b) determining whether or not the values of the bits are all the same in each bit of the bit data group of the plurality of bit groups divided into in step (a); (c) inverting at least one of the values of the bits of the bit group determined in step (b) that the values of the bits are all the same; and (d) arranging the plurality of bit groups, each of which has at least one of the values of the bits inverted in step (c), in the plurality of bit data groups except the one bit data group at regular intervals.
