Patent ID: 8036302

Claim:
An apparatus with communication capability connected to another apparatus through a communication path to communicate with the other apparatus, comprising: a receiving unit that receives specific data from the other apparatus; an optimization processing unit that determines optimal setting information about a preemphasized component of the specific data; and a transmitting unit that transmits the optimal setting information to the other apparatus, wherein for a first specific data item in the specific data transmitted in such a manner that one bit of the logical value 1 and one bit of the logical value 0 are alternately transmitted with the preemphasized component and a second specific data item in the specific data transmitted in such a manner that a plurality of bits of the logical value 1 and a plurality of bits of the logical value 0 are alternately transmitted, the optimization processing unit compares the amplitude of the first specific data item with the amplitude of the second specific data item to determine the optimal setting information about the preemphasized component such that the amplitude of the first specific data item equals the amplitude of the second specific data item.
