A communication system, reception apparatus and method, recording medium and program are provided. A technique is provided wherein, even where means for synchronizing a reception clock with a transmission clock is not available, data transmitted can be received accurately with a high transmission capacity assured. The frequency of a transmission clock used by an apparatus of the sender side of data is set equal to that of a reception frequency used by an apparatus on the receiver side. If a sampling timing and a changing point of the value of transmission data do not coincide with each other, then the value of 1 or 0 of a noticed bit is decided from a sample value. However, if they coincide with each other, then the sample value assumes an intermediate value different from 1 and 0, and the value of the noticed bit is decided as a value opposite to the value of the immediately preceding bit.
