Patent ID: 7499514

Claim:
A reception apparatus which receives, using a clock of a predetermined frequency as a reception clock, predetermined data transmitted thereto using a clock of a frequency equal to that of the reception clock as a transmission clock, comprising: a decision section for deciding, where a sample value obtained by sampling a signal representative of the predetermined data in accordance with a cycle which depends upon the reception clock is within an intermediate range between a first range within which the value of a noticed bit can be decided to be 1 and a second range within which the value of the noticed bit can be decided to be 0, the value of the noticed bit as a value opposite to the value of the immediately preceding bit; and an acquisition section for acquiring the predetermined data based on a result of the decision by said decision section; wherein the predetermined data have a synchronizing signal part and an information signal part, the synchronizing signal part including a pattern of 1 and 0 which is not included in the information signal part; and wherein, when said decision section settles the value of a bit depending upon the synchronizing signal part and is to decide the value of a bit following the settled bit, when the sample value is within the intermediate range between the first and second ranges, then said decision section decides the value of the noticed bit as a value opposite to the value of the immediately preceding bit.
